Apparatus for mounting a bearing or other device and tapered adapter onto a shaft

Abstract

An assembly and method is provided for properly securing a device such as a bearing, pulley, sheave or the like to a shaft wherein a split tapered adapter is received about the shaft, the adapter having a first end of lesser diameter, a second end of greater diameter, and a tapered surface therebetween, and threads defined about the first end of the adapter, a locknut is in threaded engagement with the first end of the adapter and a device received about the adapter. The locknut has a set of set screws carried therethrough and spaced therearound which are controlled such that the force developed thereby is adequate to clamp the adapter to the shaft and seat the device on the adapter yet is inadequate to move the device toward the second end of the adapter. A second plurality of set screws may be received through said locknut which generate adequate force to move the device up the adapter to achieve a predetermined location of the device. Alternatively, the locknut may be turned a predetermined member of degrees of rotation to force the device up the adapter by a predetermined amount. The adapter and locknut are also claimed.

Dependencies are inferred from the claim text.
