Gear transmission

摘要

Gear equipment for transferring rotary motion with torques of middle and high values. Between cooperating transmission members having offset parallel axes and confronting corresponding combined transfer grooves there are disposed anti-friction transfer elements in the form of balls. The transfer elements are rotatably disposed in equally angularly relationship in a circle in a guide gear which is rotatably mounted about a fixed axis between the transmission members. The guide cage may have uniformly circularly arranged inserts wherein the transfer elements are rotatably mounted.
