Abstract
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.
Claims6
A gear equipment for transmitting rotating motion, comprising a first and a second parallel confronting disc-like transmission member rotating about parallel offset axes, the confronting faces of the transmission members being provided with face transfer grooves in which there are positioned anti-frictionally disposed transfer elements, in the form of balls, a guide gear including a guide plate which is disposed between the transmission members and which retains the balls uniformly spaced angularly in a circle, and means mounting the guide plate for rotation about a fixed axis parallel to said axes of the transmission members.
