Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing example:

[0015] The present invention replaces the current snap-ring type spring steel retaining ring with the retaining ring and its assembly process provided below to realize the axial positioning of the bearing on the shaft parts and finally fix the bearing.

[0016] Referring to Fig. 3, the retaining ring 4 provided by the present invention is a closed-loop body, one end of which is provided with an inner tapered surface 4a, and the material is low carbon steel. For ease of assembly, the inner hole of the retaining ring 4 can be slightly larger than the inner hole of the bearing it is positioned on. In order to meet the requirements of good plasticity, easy deformation and more economical, the material of the retaining ring is best to choose No. 10 or No. 20 low-carbon steel, which is directly cut without heat treatment. The inner tapered surface 4a provided on the reta...

Abstract

A method of fixing a bearing at axis parts is that a low carbon steel closed-ring retainer ring is adopted and designed; the retainer ring, a bearing and other relevant parts are installed at the axis parts according to the assembling sequence; the circle of the retainer ring is pressed uniformly and synchronously along the radial direction to ensure that the retainer ring is extruded and transmuted inside a retainer ring installing slot to be filled in an actually existent axial gap at the position. The present invention solves the problem that the usual method adopts a clasp-type spring steel retainer ring to position the bearing, so the axial gap caused by the error accumulation of an assembling chain results in the axial move of the bearing to influence the product performance. The present invention is especially conducive to the prompt assembly of the axis parts with compact structure and relevant parts and can reduce the axial size precision requirement to other relevant parts.

Description

technical field [0001] The invention relates to axial positioning and fixing of rolling bearings. Background technique [0002] The structure of the parts where the shaft parts are located is relatively compact, and the axial positioning of the bearing 3 is realized by installing a snap ring type spring steel retaining ring 2 (as shown in Figure 1) on the shaft parts 1, as shown in Figure 2. Since the machining error of the parts involved in the dimensional chain can only be controlled within a reasonable range, the axial gap on the parts where the shaft parts are located is unavoidable. This can cause the bearing to move axially, affecting the performance of the product. Contents of the invention [0003] The purpose of the present invention is to provide a method for fixing bearings on shaft parts, so as to eliminate the axial clearance that can cause the bearings to move after assembly, and facilitate the rapid assembly of compact shaft parts and other related parts. ...
