Abstract

A rolling element shaft assembly includes a solid shaft having a first end and a second end, a tubular shaft configured to receive the shaft first end, and a bearing sleeve coupled to the solid shaft. The bearing sleeve includes a first portion defining a first edge, a second edge, and at least one first bearing aperture, and a second portion defining a third edge, a fourth edge, and at least one second bearing aperture. The first portion is configured to couple to the second portion about the solid shaft. The bearing sleeve further includes at least one first bearing disposed within the at least one first bearing aperture and at least one second bearing disposed within the at least one second bearing aperture.

First claim

Having thus described the invention, it is claimed:

1. A bearing sleeve for a rolling element shaft assembly having a solid shaft, the bearing sleeve comprising:
a first portion defining a first edge, and a second edge, each axially extending between a first portion first end and a first portion second end, and a first plurality of ball bearing apertures disposed between a first plurality of protrusions radially extending from an inner surface of the first portion, the first plurality of ball bearing apertures and the first plurality of protrusions are axially aligned and axially extend between the first portion first end and the first portion second end;
a second portion defining a third edge, and a fourth edge, each axially extending between a second portion first end and a second portion second end, and a second plurality of ball bearing apertures disposed between a second plurality of protrusions radially extending from an inner surface of the second portion, the second plurality of ball bearing apertures and the second plurality of protrusions are axially aligned and axially extend between the second portion first end and the second portion second end and are circumferentially spaced apart from the first plurality of ball bearing apertures and the first plurality of protrusions, the first portion configured to couple to the second portion about the solid shaft;
a first plurality of ball bearings received within the first plurality of ball bearing apertures and retained between the first plurality of protrusions, and a second plurality of ball bearings received within the second plurality of ball bearing apertures and retained between the second plurality of protrusions; and
at least one hinge coupled between the first edge and the third edge.

2. The bearing sleeve of claim 1 , further comprising:
at least one clip member extending from the second edge; and
at least one clip aperture formed in the fourth edge, the at least one clip aperture configured to receive the at least one clip member to couple the first portion and the second portion.

3. The bearing sleeve of claim 2 , further comprising:
at least one additional clip member extending from the fourth edge; and
at least one additional clip aperture formed in the second edge, the at least one additional clip aperture configured to receive the at least one additional clip member to couple the first portion and the second portion.
