Example Embodiment

[0017] Example 1

[0018] A bearing axial pre-tightening mechanism includes a bearing cover, a pre-tightening cover, a pre-tightening screw and its lock nut; the end face of the bearing outer ring is axially positioned with the pre-tightening cover, and the pre-tightening screw pushes the bearing outer ring axially through the pre-tightening cover , Realize the axial preload of the bearing and lock it by the lock nut.

[0019] There is a threaded hole in the center of the bearing cover, and the pre-tightening screw is installed in the threaded hole in the center of the bearing cover. The edge of the pre-tightening cover has an annular boss, the inner diameter of the boss is larger than the outer diameter of the bearing inner ring, and the end surface of the bearing outer ring is pushed through the end surface of the boss.

[0020] The specific implementation process of this embodiment:

[0021] Install the bearing in the mounting hole of the rack, and cover the inner hole of the bear...

Abstract

The invention relates to an axial pre-tightening mechanism for a bearing, and belongs to the technical field of mechanical engineering. The axial pre-tightening mechanism for the bearing comprises a bearing cap, a pre-tightening cap, a pre-tightening screw and a lock nut of the pre-tightening screw. The end face of the outer ring of the bearing and the pre-tightening cap are positioned in the axial direction, the pre-tightening screw pushes the outer ring of the bearing in the axial direction through the pre-tightening cap, and thus the bearing is pre-tightened in the axial direction and locked through the lock nut. The axial pre-tightening mechanism for the bearing has the advantages of being scientific in design, convenient to use, easy to adjust, safe, reliable, capable of being widely used for installation pre-tightening of angular contact ball bearings, conical roller bearings and other bearings, and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a bearing axial pre-tightening mechanism. Background technique [0002] Bearings bearing axial loads, such as angular contact ball bearings and tapered roller bearings, require not only axial positioning but also axial preload during installation to ensure smooth operation and bearing life. [0003] At present, the axial preload of the bearing usually adopts two ways of washer adjustment and nut adjustment. These two adjustment methods all need to unload the bearing cap, and the process is complicated. The gasket adjustment is also restricted by the thickness of the single-piece gasket, and the preload effect is highly dependent on the worker's technology. Contents of the invention [0004] The present invention provides a bearing axial pre-tightening mechanism to solve the technical problems existing in the known technology. [0005] The purpose o...
