Abstract:

A transmission comprising an outer hollow stationary casing having first and second open ends, an outer surface and a cylindrical inner surface. The inner surface has a circumferentially extending, uniformly shaped first zigzag groove. A first hollow cylindrical member is rotatably mounted coaxially within the casing and has an axially aligned output shaft which extends outwardly from the second end of the casing. The cylindrical member has a plurality of transversely extending parallel slots extending therethrough which register with the first zigzag groove. A second hollow cylindrical member is rotatably mounted coaxially within the first cylindrical member and has an output connector extending outwardly from the closed end thereof. A circumferentially extending, uniformly shaped second zigzag groove is formed on the outer surface of the second cylindrical member and registers with a portion of each slot. A bearing is operably journaled within each slot and is received between the first and second zigzag grooves to rotatably support and operably connect the second cylindrical member within the first cylindrical member and the first cylindrical member within the casing.
