Abstract:
1. A system for mounting a bearing assembly to a shaft wherein the bearing assembly comprises an inner ring and an outer ring concentrically disposed about the inner ring, with rotational elements disposed between the inner ring and the outer ring, the system comprising: an internal flange axially securable to the inner ring of the bearing assembly; an external flange secured to the internal flange via a plurality of fasteners, the external flange having an internal hydraulic chamber; a sleeve having a tapered outside diameter, the sleeve configured to be driven between the bearing assembly and the shaft; a piston configured to seal the internal hydraulic chamber and to drive the sleeve to an initial position between the bearing assembly and the shaft via a pressure loaded hydraulic fluid contained in the chamber; and means for securing the piston against the sleeve; wherein the external flange, the internal flange, and the piston are configured to remain in place secured solely to the inner ring during rotation of the shaft after the bearing assembly is installed on the shaft; wherein the external flange, the internal flange, and the piston rotate with the inner ring of the bearing assembly during rotation of the shaft after the bearing assembly is installed on the shaft; and wherein the piston is secured against the sleeve during rotation of the shaft after the bearing assembly is installed on the shaft.
