ABSTRACT:
Thermal expansion within a gearbox causes relative motion of all of the component parts therein. For gearboxes having components made of different materials, differential thermal expansion may alter the clearances between meshing gears and give rise to increased backlash. The gearbox comprises a compensation member arranged to move one end of an axle having a first gear therein in response to changes to temperature so as maintain the first gear in substantially temperature invariant engagement with a second gear.
