PURPOSE:To surely transmit large torque, by transmitting the torque between output rings and output transmission rings through steel balls. CONSTITUTION:Both output connecting rings 6, 7 are turned with output rings 4, 5 respectively as an integral unit, and the integral action of the rings is performed in such a manner that a spot facing 17 is respectively formed on the peripheral surface of the output rings 4, 5 while a spot facing 18 is respectively provided on the internal peripheral surface of the output connecting rings 6, 7, here arranging steel balls 16 and calking the periphery of the spot facing 18 or adhesively attaching the steel balls 16 to be fixed. Torque between the output rings 4, 5 and the output connecting rings 6, 7 is transmitted through the steel balls 16. The torque, which can be transmitted, is determined by the rigidity of the steel ball 16, and the very large torque can be transmitted. While the spot facing 17 formed on the output rings 4, 5 causes a fine change of sectional area, generating a stable pre-load obtained by the output rings 4, 5. |
