Epicyclic gear train

摘要

The present disclosure relates to an epicyclic gear train comprising a driving pinion (3), driving a plurality of planetary gears (7). Each planetary gear rotates around a planetary axis (23), which has first (9) and a second (11) interconnected gears with different numbers of teeth. The first gear (9) meshes with a first ring gear (19), which is stationary, and the second gear (11) meshes with a second ring gear (25) which is thereby made to rotate about a central axis (21) of the planetary gearing. An adjusting arrangement is arranged to alter the distance between the central axis (21) and each planetary axis (23), such that gearing backlash can be substantially eliminated.
