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 follower configured to extend through an opening in a cover connected to a wheel hub, the cover covering the wheel hub such that the cover inhibits access to an end of a shaft of the wheel hub assembly, said follower configured to contact said end through said opening;
said follower received in a holder engageable with the cover such that said follower is movable relative to said cover and said holder to allow said follower to extend from said holder to contact the end of the shaft;
a frame having a measurement probe attached thereto, said probe configured to contact said follower and measure relative movement of said follower 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; and
a handle connected to said frame, 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 follower configured to extend through an opening in a cover connected to a wheel hub. The cover covers the wheel hub such that the cover inhibits access to an end of a shaft of the wheel hub assembly, and the follower is configured to contact the end through the opening. The follower is received in a holder engageable with the cover such that the follower is movable relative to the cover and the holder to allow the follower to extend from the holder to contact the end of the shaft. A frame has a cavity receiving a measurement probe extending outwardly from the cavity. The probe contacts the follower and is configured to measure movement of the follower 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.

13. A method for determining an endplay of a bearing of a wheel hub assembly mounted on a shaft, the method comprising;
-
extending a follower through an opening in a hub cover covering a hub of the wheel hub assembly and extending away from the hub, the follower contacting 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 follower; applying a force to the apparatus to move the hub in a first axial direction until a cessation of movement of the hub, determining a first measurement of the probe; applying a force to the apparatus 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 follower by the probe to determine an endplay of the bearing by comparing the first measurement to the second measurement. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A system for use in measuring an endplay of a bearing of a wheel hub assembly, the system comprising:
-
a follower configured to extend through an opening in a cover connected to a wheel hub, the cover covering the wheel hub such that the cover inhibits access to an end of a shaft of the wheel hub assembly, said follower configured to contact said end through said opening; said follower received in a holder engageable with the cover such that said follower is movable relative to said cover and said holder to allow said follower to extend from said holder to contact the end of the shaft; a frame having a measurement probe attached thereto, said probe configured to contact said follower and measure relative movement of said follower 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; andwherein said frame is spaced from said follower when said follower contacts the shaft to allow said frame to move toward and away from said follower and to allow said probe to measure movement of said frame relative to said follower.
