SHAFT GEAR COMPRISING A CUP-SHAPED OUTPUT RING IN A BEARING RING

摘要

A shaft gear includes a housing in which a bearing gear is fixed, and a cup-shaped output ring driven about an axis and including a deformable wall which defines a geared flexible strip. The output ring is disposed inside of the bearing gear and is deformed by a rotating eccentric, whereby the geared strip revolves around a geared surface of the bearing gear. The geared strip and the geared surface have a truncated conoidal shape in order to minimize the risk of breaking-off the geared strip.
