Abstract
A gear train enables rotational drive in either sense of a driven member le preventing transmission of rotation in either sense from the driven to the driving member. Each member of the train comprises a pair of discs attached on their faces with each disc having asymmetric teeth on its periphery and each disc of the pair being a reflection about a diametral line of the other. The asymmetrics in each member of the train are different.
Claims5
A gear train in which rotation in either sense may be transmitted from a driving gear to a driven gear and transmission of rotation in either sense from the driven gear to the driving gear is blocked, wherein each gear comprises a pair of discs fastened together on their faces, each disc of each pair having assymetric teeth on its periphery and being a reflection about a diametral line of the other disc of the pair, the juxtaposed teeth of each assembled pair appearing symmetric when the assembled pair is viewed in plan.
