Setting of wheel hub assembly having a spacer therein

摘要

A method for setting a wheel hub assembly having a spacer therein, mounted on an axle, shaft or spindle or includes a cap a shaft is disclosed. The method is used on a wheel hub assembly having a spacer and bearings therein mounted on the axle, shaft or spindle. A retaining nut on the wheel hub assembly is tightened to the manufacture's specified torque for a particular wheel hub assembly for securing said assembly together. The wheel hub of the hub assembly is rotated when the nut is torqued to set the bearings. The retaining nut is loosened after rotating and the endplay within the wheel hub assembly is measured using an endplay measuring tool. The torque on the retaining nut is then adjusted to obtain a desired endplay measurement for the wheel hub assembly. The resultant torque on the nut at the desired endplay measurement is different from the manufacturer specified torque for the wheel hub assembly.

1. A method of setting a wheel hub assembly having a spacer therein on a shaft, axle or spindle comprising:
accessing a wheel hub assembly having a spacer and at least one bearing therein mounted on a shaft, axle or spindle; torquing a retaining nut on the wheel hub assembly to a specified torque for said wheel hub assembly, said torque specified by a manufacturer of said wheel hub assembly as a final desired torque, said retaining nut securing said assembly together, wherein a compressive load is applied to said spacer and said at least one bearing; rotating a wheel hub of said wheel hub assembly to set said at least one bearing; reducing the torque on said retaining nut after said rotating step to a torque less than said specified torque; measuring endplay within said wheel hub assembly using an endplay measuring tool by applying a force to said tool to move said hub in a first axial direction until a cessation of movement of said hub at a first position, applying a force on said tool in a second axial direction opposite to said first axial direction until a second cessation of movement of said hub at a second position, determining a first measurement at said first position and a second measurement at said second position to measure relative movement between a structure of said tool and said shaft to determine said endplay of the bearing by comparing said first measurement to said second measurement; and adjusting the torque on said retaining nut to obtain a desired endplay measurement of said wheel hub assembly, wherein the resultant torque on said retaining nut at said desired endplay measurement is different from said specified torque for said wheel hub assembly.
