Arrangement for clamping inner bearing race to non-circular section shaft and for preventing axial load in the bearing, axial creep and rotational knock

Abstract From the Canadian patent

Each end of a roller is defined by a stub shaft that is non-circular in cross section and supported from a side wall for rotation by a ball bearing having an inner, race containing a mounting hole that is shaped complementary to and located , on, the stub shaft. The inner race is clamped from moving axially or radially relative to, the shaft, thereby preventing the bearing from knocking against the stub shaft during, operation. According to one embodiment of the invention the outer race of the, bearing is mounted within a complementary shaped bore of a sleeve that has a cylindrical exterior surface and is, in turn mounted for axial movement in a , cylindrical bore of a bearing housing …
