Problems solved by technology

However, the installation of these wedge bearing assemblies on the shaft is difficult because the inner ring tends to rotate with the nut without moving the inner ring axially relative to the sleeve, and the tightness of the nut is not easily determined, which results in the Either too tight or not tight enough, the axial fixation of the nut relative to the sleeve is difficult

Embodiment Construction

[0017] Such as Figure 1-3 As shown, a wedge bearing assembly 10 is mounted on a shaft 12 having a longitudinal axis 14 . The bearing assembly 10 includes an adapter sleeve 16 that frictionally fits the shaft 12, an inner race 18 that presses the adapter sleeve 16 against the shaft 12, and a lock nut assembly that includes an axial Securely secure and engage the lock nut 20 of the inner race 18. Turning the lock nut 20 in a first rotational direction draws the inner race 18 over the adapter sleeve 16 to mount the bearing assembly 10 to the shaft 12 . Turning the lock nut 20 in a second, opposite rotational direction pushes the inner race 18 away from the adapter sleeve 16 to remove the bearing assembly 10 from the shaft 12 .

[0018] A cylindrical adapter sleeve 16 extends along the axis 14 of the shaft 12 between the first and second ends 22, 24 of the adapter sleeve and has a radially inwardly facing surface 26 and a radially outwardly facing surface 26. Surface 28. The ...

Abstract

A wedge-type bearing assembly includes a split cylindrical adapter sleeve for wrapping around a shaft. The sleeve has a radially outwardly facing tapered surface. An inner ring encircles the adapter sleeve and has a radially inwardly facing surface engaging the tapered surface of the adapter sleeve. In one embodiment, a visual indicator fixed to a lock nut connecting the adapter sleeve and inner ring indicates when the adapter sleeve is sufficiently tightened onto the shaft. In another embodiment, a positive locking key prevents rotation of the inner ring relative to the adapter sleeve.

Description

technical field [0001] The technical field of the invention is bearings and, in particular, shaft mounted wedge bearing assemblies. Background technique [0002] It is generally known to mount a bearing assembly on a shaft using a set of screws or an eccentric collar which locks the inner race of the bearing assembly to the shaft. In such a design, the inner race of the bearing assembly extends longitudinally along the shaft and is received within a mechanism that seals the inner race to the shaft and locks the bearing assembly to the shaft. [0003] It is also known to provide bearing assemblies with an inner ring having a tapered bore extending through the inner ring and loosely surrounding the shaft. The design of such bearing assemblies also includes a cylindrical wedge or a tapered mounting adapter sleeve, which is also placed on the shaft. The sleeve has a longitudinally extending slot that allows the sleeve to be placed on the shaft but provides a compressive force ...
