ABSTRACT:
A compressor includes a power transmission mechanism. The power transmission mechanism includes a shaft, and a first rotation member fixed to the shaft. The first rotation member includes a plurality of accommodation portions. The power transmission mechanism also includes a second rotation member rotatably arranged around the periphery of the first rotation member. The second rotation member has an inner surface facing the first rotation member, and the second rotation member includes a plurality of recessed hollows formed in the inner surface. The compressor further includes a plurality of balls. During operation, a first portion of each of the balls is positioned within a corresponding one of the accommodation portions, and a second portion of each of the balls is positioned within a corresponding one of the hollows, such that a rotational motion of the second rotation member is transmitted to the first rotation member via the balls. The compressor also includes a ring plate adapted to apply a predetermined amount of force to the balls. The predetermined amount of force is sufficient to maintain the balls within their corresponding accommodation portion. Moreover, the second rotation member includes one or more stopper portions which prevent the balls from moving in an axial direction within their corresponding hollow.
