Rotating mechanism fitted to lever arm comprises rotating part connected coaxially by transmission arm to second rotating part, transmission arm articulated by ball joint on frame

摘要

The mechanism comprises a first rotating part (1) which is connected coaxially by a transmission arm (2) to a second rotating part (3) for the transmission of a torque from one part to the other. The transmission arm is connected to each rotating part near their periphery. The transmission arm is articulated in a ball joint (5,6) on a frame (4).
