Abstract:
A method of mounting a bearing onto a shaft, said method comprising the steps of:a) supporting a shaft having a shoulder, a tapered surface adjacent to said shoulder and a threaded portion adjacent to said tapered surface; b) sliding a first shim onto said shaft until said first shim abuts said shoulder, said first shim having a predetermined thickness; c) sliding a bearing onto said tapered surface, said bearing having an inner race, an outer race and a plurality of roller elements positioned therebetween; d) tightening a lock nut onto said threaded portion of said shaft to expand said inner race and force said inner race into contact with said first shim, thereby preloading said bearing; e) connecting said outer race of said bearing to a motor and operating said motor at a predetermined speed; f) measuring a torque required to rotate said outer race of said bearing; and g) comparing said measured torque to a predetermine torque range to determine if said bearing is precisely preloaded.
