Systems and methods for measuring bearing endplay
First Claim
1. A system for use in measuring an endplay of a bearing of a wheel hub assembly, the system comprising:
- a cap attachable to an end of a shaft of the wheel hub assembly;
a frame having a measurement probe attached thereto, said probe configured to contact said cap and measure relative movement of said cap to determine an endplay of a bearing of the hub assembly on the shaft;
said frame comprising a plurality of legs extending from said frame to a hub of the hub assembly mounted on said shaft and coupled to said bearing to support said frame relative to the hub;
a handle connected to said frame, said handle extending substantially perpendicularly relative to an axis of the shaft and extending to opposite sides of the axis; and
said frame, said plurality of legs and said handle sufficiently rigid to allow a user to apply a force to said handle to move the hub in an axial direction relative to the shaft until a cessation of movement of the hub relative to the shaft.

Abstract
A system for use in measuring an end play of a wheel hub assembly includes a cap attachable to a shaft of a wheel hub assembly. A frame has a cavity receiving a measurement probe extending outwardly from the cavity. The probe contacts the cap and is configured to measure movement of the cap to determine endplay of the bearing assembly on the shaft. The frame includes a plurality of legs extending from the frame to a hub mounted on the shaft and coupled to the bearing to support the frame relative to the hub. The handle is connected to the frame and extends substantially perpendicularly relative to an axis of the shaft and extends to opposite sides of the axis. The frame, the plurality of legs and the handle are sufficiently rigid to allow a user to apply a force to the handle to move the hub in an axial direction relative to the shaft until cessation of movement of the hub relative to the shaft.

12. A method for determining an endplay of a bearing of a wheel hub assembly mounted on a shaft, the method comprising;
-
attaching a cap to an end of the shaft; connecting a plurality of legs of an endplay measuring apparatus to a hub of the hub assembly mounted on the shaft; connecting a measurement probe to a frame of the apparatus; the probe contacting the cap; applying a force to a handle of the apparatus connected to the frame and the plurality of legs to move the hub in a first axial direction until a cessation of movement of the hub, the handle extending substantially perpendicularly relative to an axis of the shaft and extending to opposite sides of the axis; determining a first measurement of the probe; applying a force on the handle in a second axial direction opposite to the first axial direction until a second cessation of movement of the hub; determining a second measurement of the probe after the second cessation of movement; and determining a movement of the cap by the probe to determine an endplay of the bearing by comparing the first measurement to the second measurement. - View Dependent Claims (13, 14, 15, 16)

17. A system for use in measuring an endplay of a bearing of a wheel hub assembly, the system comprising:
-
a cap attached to an end of a shaft of a wheel hub assembly; a frame having a measurement probe connected thereto, said probe contacting said cap and configured to measure relative movement of said cap to determine an endplay of a bearing of said hub assembly on said shaft; said frame comprising a plurality of legs extending from said frame to a hub of said hub assembly mounted on said shaft and coupled to said bearing to support said frame relative to the hub; a handle connected to said frame, said handle extending substantially perpendicularly relative to an axis of said shaft and extending to opposite sides of the axis; said frame, said plurality of legs and said handle sufficiently rigid to allow a user to apply a force to said handle to move the hub in an axial direction relative to said shaft until a cessation of movement of said hub relative to said shaft; and said hub rotatable by said handle.
