Installation, Operation and Maintenance

Installation

Sequence of operations

1. Check that the shaft end is running true.
   

2. Fit the keys into keyways and lubricate the shaft (eg. with Molykote etc.)
   

3. Place the turbo coupling on the shaft (see fig. 6).
   

4. Using the mounting spindle and the thrust disc, the turbo coupling is mounted on the shaft, (Fig. 7). 
   The coupling hub must press against either the shaft; collar or face of the shaft end dependant on the variant
   

5. The coupling must be fixed axially by means of holding screw, lock washer and retaining ring. 
   Rotation of the retaining ring is prevented by a locking pin or a spring washer. (Figs. 8 and 9).
   

6. Mounting the hub of the connecting coupling.

Figures 6 to 11

Unsuitable mounting aids (eg. pressure plates, hammer, welding torches etc.) must not be used. (Figs. 10 and 11)

Alignment

Always remember that only a perfect alignment of motor and gear shafts ensures a smooth running of the turbo coupling and a long life for the whole unit.

Sequence

1. The driving machine must be mounted in its final position. The foundation bolts must be firmly tightened.
   

2. Fit the flexible element in the connecting coupling.
   

3. Push the motor up to the driven machine. To allow the motor to be correctly aligned, the feet should be adjusted by means of shims or foil plates. Locking plates and adjusting bolts on the foundations are an advantage for sideward adjustment.

There are several possibilities for aligning by means of depth gauge is sufficient. A more precise alignment by means of a dial gauge is also possible. This method is shown in Fig. 13.

Figure 12 and 13

Flexible Couplings; alignment value and tolerances.

Figure 14

The alignment tolerance for the various types and sizes of couplings are listed in the table.

To eliminate axial restraint forces, the dimension "L" must be maintained under all circumstances.

Both the driving and driven shafts should align in operation. When aligning, the extension of the shafts due to warming-up in operation must be taken into account.

When the motor foot bolts and flange bolts of the connecting coupling have been tightened, the alignment should be rechecked.

Permissible alignment tolerances
(Valid for all connecting couplings).

Dial gauge readings via radial displacement of the shaft, (measured in the area of the flexible seal) and deviations in trim (measured at the largest diameter) All values in mm.

The flexible connecting couplings can only take up a limited shaft extension.
We recommend that the value 0 should be aimed for, for wear reasons.

Filling Fluids and Quantities

The oil filling has a considerable influence on the torque transmitted by the turbo coupling.

The quantity of fluid to be filled into every coupling is given in the order confirmation or the filling quantity can be estimated in accordance with the motor power.

The exact quantity to be filled should be determined from the actual power transmitted or by measuring the coupling slip and motor current.

Normal operating conditions

The following operating fluids have proved satisfactory under normal operating conditions:

Viscosity	:	ISO VG 22
		ISO VG 32
Pour point	:	below -24deg C (-11,2 deg F)
Viscosity on starting	:	< 15 000 mm2/sec.
Flash point	:	> than or equal to 175 deg C (347 deg F)

Refined product, highly resistant to ageing. Compatibility with seal materials of Perbunan or Viton.

Exceptional operating conditions
Often, in the course of completing an order or during tests, special operating conditions are determined. If conditions should change, we ask that you should refer to us.

Important exceptional conditions can be:
high ambient temperature,
high starting frequency,
high moment of inertia.
For such applications, a mineral oil should be selected with particularly good oxidation resistance.

Starting and operating at low ambient temperatures :
The pour point of the mineral oil should be similar to or below the lowest coupling starting temperature.

Application in explosion-proof areas :
Dependent on the explosion-protection requirements special criteria are to be considered for oil filling determination. For this case the guide values in the filling quantity tables on page 8 and 9 are not suitable. In few cases the filling quantity specified by the supplier (in the order confirmation or on the labels) is to be observed.

The greater the filling volume, the greater the motor load on starting and the smaller the slip for the same torque transmission and thus the greater the slipping torque.

Water used as operating medium :
Please refer to our supplement No. 3.626-7432 e which describes specifically the difference between water coupling and the oil couplings outerhed in this manual.

When using high-flash paint pressure fluids :
The seal material must be Viton. The filling quantities will differ from those used for mineral oils (ask Voith for details).

The manufacturer's usage directions should be followed. Fluids on a phosphoric acid ester basis must not be allowed to escape into the environment. Any such fluid that escapes should be absorbed with sand and destroyed by high-temperature combustion. In order that the fluid in the coupling does not spray out through the fusible plug, we recommend the fitting of a thermostatic switching element.

Special instructions apply to applications for underground mining.

Special requirements for high-flash point pressure fluids :
Viscosity: up to approx. 35 mm²sec. at 40 deg C (104 deg F)
Highly resistant to ageing and compatible with Viton as sealing material.

High-flash point pressure fluids for general application (not for mining operations below ground) :
BP Olex SF-D 0207 ZF
Mobil control fluid HFD 46 (starting temperatures not below -20 deg C [-4 deg F]).

Mineral oils for normal operating conditions :

Filling and Filling Control

Figure 15

The correct oil filling level is important for the trouble-free operation of every Voith Turbo coup- ling. For this reason we recommend that the oil level be checked at regular intervals.

Warning: Voith Turbo couplings may only be filled to a maximum of 80% of their total capacity. No attempt should be made to top up the filling by rotating the secondary parts or by pouring oil through the fusible plug screw bore, since any excess oil, when heating up, would tend to build up an inadmissible pressure inside the coupling while in operation.
Damage (from simple leakage up to complete mechanical breakdown) to the Voith Turbo coupling could be the result.

Filling and checking of the filling level are carried out as follows :

Horizontally installed couplings :

Filling :
1 .Remove the filling plug
2. Remove the topmost fusible plug.
3. Fill the coupling with the prescribed quantity of oil.
4. Rotate the coupling until oil just begins to spill out of the fusible plug hole.
5. To provide a means of checking the oil level, make a mark on the coupling and another mark opposite to it on the driven machine or guard with the coupling in this position.
6. Replace the filling plug and fusible plug and tighten.

Checking :
1. Remove the filling plug and topmost fusible plug.
2. Turn the coupling until the checking marks (see 5 above) are in line with one another.
3. Top up if necessary.
4. Close the openings oil tight.

By means of our sight glass (for turbo couplings from size 366) a check of the filling quantity is possible without opening the turbo coupling. Also please refer to print CR 160.

Important :
Screw the sight glass into the turbo coupling axially only.
For sizes 366 and 422 a subsequent installation is possible by replacing the sight glass by a blind screw. For sizes 487 to 1150 a standard sight glass is available.

Vertically installed couplings :

Filling :
1. Remove the filling screw.
2. Mount the filling control device (see installation plan, special accessory Item No. 1300).
3. Fill the coupling with the prescribed quantity of oil.
4. Mark the level of the oil in the gauge pipe or on the gauge hose on the coupling.
5. Close the filling plug.
6. Remove the filling control device and close off the valve with a screwed plug.

Checking :
1. Remove the filling screw.
2. Mount the filling control device.
3. Check the filling level against the marks.
4. Top up if necessary.
5. Close the filling plug.
6. Remove the filling control device and close off the valve with a screwed plug.

With multiple-motor drives, the oil fillings of the different turbo-couplings must be matched so as to obtain proper load distribution.

Warning!
The load matching check should still be made even when the motors used are identical and the same turbocouplings are used (due to tolerance characteristics).

Such load distribution can best be achieved by connecting an ammeter in series with each motor. Should
the readings on the ammeters differ, the oil fillings should be corrected until each motor draws approximately the same current from the mains.

Please note:
A sufficiently sized oil catch pan should be placed underneath the turbo coupling for filling and draining, to prevent that oil gets in the soil.

Commissioning

Note: When switching off the unit, do not touch the turbo-coupling without protecting your hands, since it may be hot.

Figure 16

The turbo couplings can principally be driven in either direction. When the installation is switched on for the first time it is important to cheek that the coupling runs in the direction required by the installation. When using a turbo coupling, the squirrel-cage motor is usually switched on directly. If the capacity of the mains supply makes a star-delta starting circuit necessary then the switch-over from star to delta must be made as rapidly as possible, at the latest after 3 seconds.

The machine protection laws require that a suitable anti-contact guard must be fitted. For details see section on Maintenance.

Cleaning the external coupling:

It is not allowed to clean the turbo-coupling by means of high-pressure cleaning equipment. It may happen that the grease in the dust lips or shaft sealing rings may be washed out or pressed underneath the sealing lip, which would cause leaks or destroy the shaft sealing ring.

When the motor rated speed has been reached, the driven machine must start to turn. If this does not happen, the cause can be excessive stiffness, or a jammed machine which must be repaired immediately.

Each turbo coupling is checked for leakage before it leaves the factory and must not lose any oil.

To ensure that the oil filler plug is closed to an oil-tight seal, and that no leaks are present, make a seal leakage test with a strip of clean paper as shown in Figure 16. Any oil spray will then become visible on the paper.

Only original sealing rings in perfect condition, and which are not deformed should be used for filling and fusible plugs. Tightening torques and dimensions of sealing rings see table in Filling and Filling Control section.

Maintenance

When the requirements for size, installation, alignment and filling have all been correctly complied with, then Voith Turbo couplings require virtually no maintenance and require virtually no operational supervision.

The temperature is highly dependent on the local operating conditions (number of starts, mass being accelerated and ambient temperature) and when in continuous operation the temperature should not exceed 85 deg C (185 deg F). To provide good cooling conditions the ventilation of the turbo coupling must not be hindered by closed surface protective guards. We recommend that all guards be constructed from expanded metal or perforated metal sheet.

For reasons of demonstration, the photos in this section do not show any guards.

A regular oil change is not necessary. Depending on the thermal stress to which the oil is subjected, the same oil filling may be used for several years. We recommend however, that the oil be checked for ageing after approximately 15,000 hours of operation, and changed if necessary.

If the flexible material of the connecting coupling suffers high wear (this should be checked periodically) the alignment should be checked and corrected where necessary.

If the fusible safety plugs have melted due to overloading or jamming of the driven machine, the coupling must be filled with new oil. It is very important that only genuine Voith fusible safety plugs be used.

After the fusible safety plugs have melted, shut off the unit to prevent the bearings from running dry.

Care must be taken to select the correct melting point fusible safety plugs.

Please note the admissible temperature limit in each case when using in an explosion-proof area.

Melting Point	Colour
110 deg C (230 deg F)	yellow
140 deg C (284 deg F)	red
160 deg C (320 deg F	green
180 deg C (356 deg F)	blue

By using our "Thermal warning equipment", the melting of the fusible safety plugs can be prevented. Remaduning by the manufacturer is only required on subsequent installation to be carried out on coupling size 274.

Warning!
The fusible safety plugs must not be exchanged for solid screws under any circumstances.
If the coupling has heated up considerably, or when the safety plugs have melted, the bolts around the circumference should be tightened.

Dismantling

Figure 17

For dismounting the turbo coupling the drive motor must be disconnected and withdrawn.

After removing the holding screws and holding disc, the turbo coupling can be withdrawn.

Warning!
The withdrawal may only be made via the steel coupling hub, with the aid
of a screw extractor. Never withdraw by means of the housing.

To ensure that the screw extractor is not applied with a bending moment, which would cause it to tip and gauge, it must be applied immediately beside the hexagonal head and the thread must be lubricated (e.g. Molycote, oil).

Repairs

Whenever possible couplings needing repair should be returned to the factory and otherwise only be repaired by correctly instructed skilled personnel.

Normally the individual parts are balanced and are interchangeable. In cases where a particularly smooth, even running is necessary, the turbo coupling is completely balanced and the parts are marked at the factory.

Dismantling :

Drain the oil out of the coupling. When the parts have been marked and the peripheral screws have been removed, the primary wheel and the casing can be removed. To prevent damage to the sealing surfaces, the removal should not be made with the aid of chisels, or screwdrivers or similar tools. Only pulling screws may be used. The parts should be carefully cleaned and the sealing surfaces carefully inspected. They may be cleaned and re-polished by means of a piece of emery cloth wrapped round a flat file.

The shaft seals should now be removed and the roller bearings, which for sizes 366 and above are fitted by means of spacer rings (spring plate) in the primary wheel and the casing should be withdrawn from the coupling hub.

If the spacer rings have been pressed into the Silumin due to poor alignment, then the seating surface can be re-turned and a steel band inserted. For this purpose however, the turbo coupling must be returned to the manufacturer.

We recommend that all shaft seals and gaskets be renewed at each dismantling.

Reassembly

Prior to pressing in the shaft sealing rings, their seating in the coupling easing and primary wheel should be coated with a sealing compound (e.g. Atmosit no Hylomar). see fig 20).

When inserting the spacer rings (Fig. 21) care must be taken to ensure that they are correctly seated. To prevent axial movement, depending on the size and type, either a groove or a cap is provided as support for the spacer ring (Fig. 22).

After inserting the ball bearing (Fig. 23) the coupling hub with the attached secondary wheel is mounted into the coupling easing (Fig.24). Subsequently, install the secondary hub with the attached secondary wheel in the coupling casing. For sealing the outer flange, place a soft woolen thread (1 00% shearing wool) coated with soft soap, or Hylomar sealing compound and Fluiflex teflon cord (1 mm diameter) on the sealing surface inside the bolt hole circle; the ends should cross (as shown in Fig. 25 and 26). The sealing surfaces must be in perfect condition. The sealing compound should be evenly applied so that the wool thread or Teflon cord is not pressed outwards by excess of sealing compound into the bolt holes during assembly.

Allow 5-10 minutes drying time for the sealing compound and then assemble the parts slowly.

After the primary wheel has been pressed on (Fig. 27) and attached to the coupling casing, the turbo coupling is again ready to go into operation.

The sealing of the "delayed filling" chamber cover of the types TV and TVV should also be checked (fig 28).

Figure 19

Figures 20 to 28

Alignment of Flange Couplings with Internal Locking Elements

1. Release all screws on the locking element a few turns

2. The locking element should be lightly oiled only on outside and taper surfaces (not on inside) with an oil which does NOT contain Molybdnum Disulphide or any other high pressure additives. Thin engine oil e.g. 1OW or 32 grade hydraulic oil.

NO anti-seize, scuff or rust paste must be used on shaft surface.

3. Shaft and inside of locking element of coupling should be oil free or cleaned with thinners.

4. Place element in position in bore of coupling.

5. Slide both coupling and element onto shaft.

Example Size SLE 560-170/210 Locking Element

TIGHTENING PROCEDURE

Figure 29

1. Tighten screws 1,2,3, and 4 with allen key, by hand ; check run-out on outer face of coupling. This should be less than 0,08 mm. Tighten and or loosen relevant screws until this tolerance is achieved. Now tighten the rest of the screws by hand to the prescribed sequence - check run-out again.

2. If run-out has been maintained below tolerance, proceed to torque tighten screws with wrench to 75% of required torque to the prescribed sequence - check run-out again. If run-out has been maintained below tolerance, tighten all screws to full torque - check run-out again.

3. Should run-out exceed tolerance at any stage of the tightening procedure, then all screws are to be loosened - locking element to be 'cracked' as per paragraph 3 under removal and tightening procedure start again from beginning.

REMOVAL

1. Loosen all bolts and remove.

2. Screw bolts into threaded holes in front and centre ring.

3. Tighten bolts, in stages, in diagonally opposed sequence until the "crack", which signals the release of the tapers is heard. The removal process can now be completed by pushing the rings apart in the above manner until the element is loose on the shaft.

4. The coupling and element can now be removed from the shaft.

Determining the Quantity of Oil in a Voith Turbo Coupling with Sight Glass Fitted

When a Voith turbo coupling is first installed, the correct oil level should be determined by either measuring the motor current or performing trial start-ups of the machine until the desired result is obtained. Once the correct filling has been established, then one of the following methods may be adopted for future filling or checking.

METHOD 1

Immediately after installation and determination of correct oil filling as explained above, proceed as follows :

1.1. Locate the oil sight glass and rotate the coupling upwards until the sight glass changes colour. (Dark to light).

1.2. Slowly rotate the coupling in the opposite direction (downwards) until the sight glass again changes colour from light to dark.

1.3. With the coupling in this position, create a reference point by marking an arrow an either the gearbox, motor or coupling guard. Alternatively, determine the height of the sight glass from the floor or base plate.

1.4. The oil sight glass should always change colour as it is brought in line with the reference mark. If not, then the oil level must be adjusted accordingly.

METHOD 2

This method necessitates the use of "OIL FILLING CONTROL TABLES", available from Surtees and Son (Pty) Limited.

2.1. Rotate the coupling until the sight glass is at the top of the coupling.

2.2. Slowly rotate the coupling towards you watching the sight glass carefully.

2.3. Stop rotating the coupling the moment the sight glass changes colour. (Light to dark).

2.4. With the coupling in this position, count the number of bolts on the periphery of the shell between the sight glass and the vertical axis (TOP) of the coupling.

2.5. Using the correct "OIL FILLING CONTROL TABLE" For the coupling concerned, read off the corresponding oil quantity versus number of bolts counted.

2.6. Adjust the oil fill accordingly.

To Determine/Check the Quantity of Oil in a Voith Turbo Coupling

The most accurate method is to drain all the oil from the coupling and measure the volume of oil, using a known volume container. However, this method is time consuming, and depending on the location of the coupling may be very messy.

An alternative method for determining/checking the amount of oil without draining the coupling will now be described step by step (in this case, it is assumed that the coupling shaft is horizontal) :

(1) Rotate the coupling until the fusible plug is near the top side of the coupling.

(2) Remove the fusible plug.

(3) Rotate the coupling until oil is about to flow out of the fusible plug hole.

(4) With the coupling in this position, count the number of bolts between the fusible plug hole and the vertical axis of the coupling.

(5) Use the table or graph for the size coupling concerned to determine the corresponding amount of oil in the coupling.

Example 1 - 422 TV Coupling (see table 3-602-7803)

From the sketched example, it can be seen that there are seven bolts between the fusible plug hole and the vertical axis. From the horizontal column of the table read off the corresponding oil filling. Example 1 = 12 litres

Example 2 - 562 TV Coupling (see table 3-602-7802)

For nine bolts between fusible plug and vertical axis, the corresponding oil filling is 30 litres.

Example 3 - 620 TV Coupling (see table 3-602-8244)

For seven bolts the corresponding oil filling is 37 litres.

NOTE : The method described above is not very accurate, therefore, pay careful attention to the procedure to ensure that the results are not too inaccurate.
