摘要

A coupling device for power transfer between drive and driven shafts (25, 26) coaxially arranged with each other for relative rotation, which includes an inner member (11) mounted on one end of the drive shaft (25) for rotation therewith and having an eccentric cylindrical support portion (11a) the central axis (A) of which is radially displaced from the central axis (B) of the drive shaft, an outer cylindrical casing (12) coaxially connected to one end of the driven shaft (26) for rotation therewith and being arranged in surrounding relationship with the support portion (11a) of the inner member, the casing having a number of internal teeth (12b) formed therein, and an inscribed gear (13) rotatably carried by the support portion (11a) of the inner member and being in meshing engagement with the internal teeth (12b) of the casing to transfer the power only from the drive shaft (25) to the driven shaft (26) in response to the difference in rotational speed between the shafts, and a separator rotatably carried by the support portion of the inner member and having a guide portion disposed between a portion of the external teeth and a portion of the internal teeth to maintain the meshing engagement of the external teeth with the internal teeth at their other portions.
