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.

Preloading nut for wedge sleeve

A wedge-shaped sleeve is inserted between the inner race of a bearing and a shaft to clamp the bearing to the shaft. The sleeve, which is resilient with a longitudinal slit, has a rib thereon to engage a groove in the bearing race to hold the sleeve and bearing in assembled relation when the sleeve is relaxed. An alternative sleeve, which is split to constitute two separate halves, is disclosed. There is also shown a bearing mounted in a bore in which the tapered sleeve is received between the bore and the outer race of the bearing.
