BEARING ASSEMBLY
First Claim
1. A bearing assembly comprising:
- a split cylindrical adapter sleeve for wrapping around a shaft, said sleeve having a radially outwardly facing surface including a radially outwardly opening circumferential groove formed at one axial end of said sleeve and a tapered section extending from said circumferential groove toward an opposing axial end of said sleeve, said tapered section having a first diameter proximal said circumferential groove which is greater than a second diameter proximal said opposing axial end of said sleeve;
an inner ring encircling said adapter sleeve and having a radially inwardly facing surface between axial ends of said inner ring engaging said tapered section of said adapter sleeve, said inner ring including inner threads formed in said radially inwardly facing surface proximal one of said axial ends of said inner ring; and
a lock nut encircling the shaft and having a radially inwardly depending hook engaging said circumferential groove, and having a radially outwardly facing surface including outer threads threadably engaging said inner threads formed in said radially inwardly facing surface of said inner ring, wherein rotation of said lock nut in one direction of rotation draws said inner ring over said adapter sleeve to compress said adapter sleeve and fix said inner bearing ring relative to the shaft, and rotation of said lock nut in a second direction urges said inner ring off of said adapter sleeve to allow expansion of the adapter sleeve and release said inner bearing ring relative to the shaft.

Abstract
A wedge-type bearing assembly that is easily dismounted from a shaft includes an adapter sleeve, an inner ring, and a lock nut. The split cylindrical adapter sleeve wraps around a shaft, and has a radially outwardly facing surface including a tapered section. The threaded inner ring encircles the adapter sleeve, and includes a radially inwardly facing surface engaging the tapered section of the adapter sleeve. The lock nut is fixed axially relative to said the sleeve and threadably engages the inner ring, wherein rotation of the lock nut in one direction of rotation draws the inner ring over the adapter sleeve to fix the inner bearing ring relative to the shaft, and rotation of the lock nut in a second direction urges the inner ring off of the adapter sleeve to release the inner bearing ring relative to the shaft.

17. A bearing assembly comprising:
-
a split cylindrical adapter sleeve for wrapping around a shaft, said sleeve having a radially outwardly facing surface including a radially outwardly opening circumferential groove formed at one axial end of said sleeve and a tapered section extending from said circumferential groove toward an opposing axial end of said sleeve, said tapered section having a first diameter proximal said circumferential groove which is greater than a second diameter proximal said opposing axial end of said sleeve;
an inner ring encircling said adapter sleeve and having a radially inwardly facing surface between axial ends of said inner ring, said radially inwardly facing surface of said inner ring defining a tapered bore mating with said tapered section of said adapter sleeve, said inner ring including inner threads formed in said radially inwardly facing surface proximal one of said axial ends of said inner ring;
an outer ring radially spaced from said inner ring;
a plurality of rollers interposed between said inner and outer rings;
a lock nut encircling the shaft and having a radially inwardly depending lip engaging said circumferential groove, and having a radially outwardly facing surface including outer threads threadably engaging said inner threads formed in said radially inwardly facing surface of said inner ring, wherein rotation of said lock nut in one direction of rotation draws said inner ring over said adapter sleeve to compress said adapter sleeve and fix said inner bearing ring relative to the shaft, and rotation of said lock nut in a second direction urges said inner ring off of said adapter sleeve to allow expansion of the adapter sleeve and release said inner bearing ring relative to the shaft; and
locking structure engaging said lock nut and said inner ring which locks said lock nut relative to said inner ring to prevent unintended rotation of said lock nut relative to said inner ring. - View Dependent Claims (18, 19, 20)
