Apparatus for preloading a bearing
First Claim
1. An apparatus for providing a preload to a bearing within a wheel hub assembly comprising:
- an attaching member releasably, threadably, and directly attachable to a circumferential outside surface of an exposed end of a threaded shaft of an axle or spindle of the wheel hub assembly, the shaft having a longitudinal axis, wherein a proximal direction extends toward a frame from said shaft, a distal direction being opposite from the proximal direction and extending toward the shaft from said frame;
said frame axially separated from, and coupled to, said attaching member to allow said frame to move relative to said attaching member in an axial direction along the longitudinal axis;
a plurality of extensions extending from said frame axially past said attaching member in the distal direction towards the wheel hub assembly, said plurality of extensions being configured to contact at least one of a wheel hub or a bearing of said wheel hub assembly when said attaching member is attached to said threaded shaft;
an adjustment mechanism configured to move said frame and said plurality of extensions axially towards said wheel hub assembly to apply a preload to a bearing within said wheel hub assembly; and
said adjustment mechanism located axially proximal relative to said frame and said attaching member, said frame located axially proximal to said attaching member and between said adjustment mechanism and said attaching member, said attaching member located between the shaft and said frame when said attaching member is attached directly to said threaded shaft.

Abstract
An apparatus for preloading a bearing includes an attaching member, a frame, a plurality of extensions, and an adjustment mechanism. The attaching member is releasably attachable to a threaded shaft of an axle or spindle of a wheel hub assembly. The frame is axially separated from, and coupled to, the attaching member to allow the frame to move relative to the attaching member in an axial direction along the longitudinal axis. The plurality of extensions is configured to contact at least one of a wheel hub or a bearing of the wheel hub assembly when the attaching member is attached to the threaded shaft. The adjustment mechanism is configured to move the frame and the plurality of extensions axially towards the wheel hub assembly to apply a preload to a bearing within the wheel hub assembly.

12. An apparatus for providing a preload to a bearing comprising:
-
a frame supporting an attaching member releasably, threadably, and directly attachable to a circumferential outside surface of an exposed end of a threaded shaft of an axle or spindle to allow said frame to move relative to said attaching member and in an axial direction along a longitudinal axis of the shaft, wherein a proximal direction extends toward said frame from said attaching member, a distal direction being opposite from the proximal direction and extending toward the attaching member from said frame; a plurality of extensions extending from said frame in the distal direction past said attaching member towards a wheel hub assembly, said extensions being configured to contact at least one of a wheel hub or a bearing of said wheel hub assembly when said attaching member is directly attached to said threaded shaft; and an automated adjustment mechanism configured to move said frame and said plurality of extensions axially towards said wheel hub assembly to apply a preload to a bearing within said wheel hub assembly. - View Dependent Claims (13, 14, 15, 16, 17)
