ABSTRACT:
A new and unique bearing block for torque transmission is disclosed which comprises a bearing block body having two rectangular recesses at both the front and rear sides, said recesses extending at a right angle relative to one another and having plural substantially semi-circular ball rolling grooves on the inner wall of the recesses, a plurality of non-loading ball holes through the bearing block body, track shafts slidably inserted through the rectangular recesses with the corresponding ball rolling grooves provided on the side walls, retainers having plural slits, side covers with ball movement direction reversing U-shaped grooves and a number of balls adapted to circulate through the loading ball rolling grooves, the U-shaped grooves and the non-loading ball holes. As a typical practical application of the bearing block an improved Oldham coupling for torque transmission is disclosed according to another aspect of the present invention. This Oldham coupling is constructed such that the bearing block of the invention is operatively connected to an input shaft as well as to an output shaft. Specifically, the bottom portion of the one track shaft laterally slidably inserted through the one rectangular recess is fixedly connected to the input shaft, whereas the bottom portion of the other track shaft laterally slidably inserted through the other rectangular recess is fixedly connected to the output shaft.
