Design for Gear and Component Interchangeability

Hansen Transmissions have standardized their gearboxes to be able to utilize a specific gear set or 'gear center distance', in different places depending on the ratio of the gearbox required and the load rating predicted to be encountered. This approach allows for versatility and 'multi-application' of standard gears in different stages of different size gearboxes.

It can be seen from the above table that, for example in a 'C' size gearbox, the low speed gear set (dark blue) is used as the high speed gear set in a 'L' and 'M' size gearbox which have much higher torque ratings. The same set of gears is also used as the first and second intermediate gear set, while moving through the range between 'C' and 'M'. With this technique manufacturing efficiency is increased and a large range of ratios is attained with minimum components. This versatility is where Hansen coined their slogan from, "Special for you, standard for us!"
