Apparatus for mounting a bearing onto a shaft
First Claim
1. An apparatus for mounting a bearing onto a shaft comprising:
- a) a base plate;
b) a support mounted to said base plate and extending upward therefrom, said support capable of supporting a shaft, said shaft having a shoulder, a tapered surface adjacent to said shoulder and a threaded portion adjacent to said tapered surface, and a shim is positioned on said shaft adjacent to said shoulder, a bearing positioned adjacent to said shim, said bearing having an inner race, an outer race and a plurality of roller elements positioned there between, and a lock nut secured to said threaded portion of said shaft which contacts and mounts said inner race of said bearing;
c) a motor mounted to said base plate, said motor having an output shaft which is axially aligned with and connectable to said outer race of said bearing, said motor capable of rotating said outer race of said bearing at a predetermined speed;
d) a force sensor attached to said motor which is capable of measuring the amount of torque required to rotate said outer race at a predetermined speed; and
e) display means for providing a visual readout of said measured torque.

Abstract
An apparatus for mounting a bearing onto a shaft is disclosed. The apparatus includes a base plate and a support mounted to and extending upward from the base plate. The support is capable of supporting a shaft. The shaft has a shoulder, a tapered surface adjacent to the shoulder and a threaded portion adjacent to the tapered surface. A shim is positioned on the shaft adjacent to the shoulder and a bearing is positioned adjacent to the shim. The bearing has an inner race, an outer race and a plurality of roller elements positioned there between. The bearing is mounted onto the shaft by a lock nut which is secured to the threaded portion of the shaft and which contacts the inner race of the bearing. The apparatus further includes a motor mounted to the base plate. The motor has an output shaft which is axially aligned with and connectable to the outer race of the bearing. The motor is capable of rotating the outer race of the bearing at a predetermined speed. A force sensor is attached to the motor which is capable of measuring the amount of torque required to rotate the outer race at a predetermined speed. The measured torque is then visually displayed on a display unit. When the measured torque is within the predetermined torque range, the bearing will be mounted.
