Abstract
Abstract A nut is provided for preloading a sleeve which is wedged between a tubular member and a shaft. The nut, which is threadedly received on the tubular member, has a resilient, radially inwardly extending portion to engage the end of the wedge sleeve. When the nut is tightened on the tubular member, the inwardly extending portion of the nut is deflected to produce a stress-created force on the wedge sleeve, continuously urging the wedge sleeve toward a tightening position between the tubular member and the shaft.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
In apparatus to mount a tubular member on a shaft comprising a wedge sleeve received between said tubular member and said shaft, a nut received on said tubular member and in threaded engagement therewith, said nut having a radially inwardly extending resilient member rigidly connected thereto to engage the outer end of the wedge sleeve as the nut is advanced and to advance the wedge sleeve between the tubular member and the shaft, the improvement wherein said tubular member has a tapered surface facing said nut and said nut has a complementary tapered surface to engage and overlay the tapered surface on the tubular member when the nut is tightened on the tubular member to impose a positive limit to expansion of the tubular member by the wedge sleeve.
Claim 2
Dependent Claim
129 words
In apparatus to mount a tubular member on a shaft comprising a wedge sleeve received between said tubular member and said shaft, a nut received on said tubular member and in threaded engagement therewith, said nut having a radially inwardly extending resilient member rigidly connected thereto to engage the outer end of the wedge sleeve as the nut is advanced and to advance the wedge sleeve between the tubular member and the shaft, the improvement wherein said tubular member has a tapered surface facing said nut and said nut has a complementary tapered surface to engage and overlay the tapered surface on the tubular member when the nut is tightened on the tubular member to impose a positive limit to expansion of the tubular member by the wedge sleeve.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1 wherein said tubular member is the inner race of a bearing.
Claim 4
Dependent Claim
155 words
In apparatus to mount a tubular member on a shaft comprising a wedge sleeve received between said tubular member and said shaft, a nut received on said tubular member and in threaded engagement therewith, said nut having a radially inwardly extending resilient member rigidly connected thereto to engage the outer end of the wedge sleeve as the nut is advanced and to advance the wedge sleeve between the tubular member and the shaft, the improvement wherein said tubular member has a tapered annular surface facing upwardly and outwardly toward the nut, and said nut has a complementary tapered annular surface facing downwardly and inwardly toward the tubular member, said tapered surface on the nut engaging and overlaying said tapered surface on the tubular member to impose an increasing radial inward force on the tubular member as the nut is tightened on the tubular member to prevent expansion of the tubular member by the wedge sleeve.
Claim 5
Dependent Claim
155 words
In apparatus to mount a tubular member on a shaft comprising a wedge sleeve received between said tubular member and said shaft, a nut received on said tubular member and in threaded engagement therewith, said nut having a radially inwardly extending resilient member rigidly connected thereto to engage the outer end of the wedge sleeve as the nut is advanced and to advance the wedge sleeve between the tubular member and the shaft, the improvement wherein said tubular member has a tapered annular surface facing upwardly and outwardly toward the nut, and said nut has a complementary tapered annular surface facing downwardly and inwardly toward the tubular member, said tapered surface on the nut engaging and overlaying said tapered surface on the tubular member to impose an increasing radial inward force on the tubular member as the nut is tightened on the tubular member to prevent expansion of the tubular member by the wedge sleeve.
