Patent number: 4189961Abstract: The speed reduction means comprises a stationary hollow cylindrical body supporting for rotation about a common axis coaxially arranged rotary input body and rotary output body. A primary set of power transmitting balls is arranged at regular intervals in two mutually shifted rows forming a zig-zag pattern between the power input rotary body and the power output rotary body. A secondary set of power transmitting balls arranged at regular intervals in a single row is disposed between the power output body and the two rows of balls in the primary set. The bearing surface of the power input body defines an eccentric portion which compresses at one point the primary set of balls in radial direction thus displacing the secondary set of balls in axial direction to meander between the two rows of balls.Type: GrantFiled: June 29, 1977Date of Patent: February 26, 1980Inventors: Toshio Yamashita, Hisashi Kaburagi
