Heavy transmission shaft middle bracket assembly with rubber vulcanized on bearing outer ring

Abstract

The invention discloses a heavy transmission shaft middle bracket assembly with rubber vulcanized on a bearing outer ring, and relates to the field of middle support assemblies; the heavy transmissionshaft middle bracket assembly comprises a fixed support and a ball bearing, the outer ring of the ball bearing is vulcanized with a rubber buffer pad at a low temperature, so that the ball bearing and the rubber buffer pad form an integrated structure; and the ball bearing is directly mounted and fixed with the fixed support through the rubber buffer pad. The heavy transmission shaft middle bracket assembly has the beneficial effects that the machining and assembling procedures of three parts, namely a bearing seat and a snap ring, are reduced, the assembling period is shortened, and the partproduction procedure is simplified; the weight of the middle support assembly is reduced, and the cost of the middle support assembly is reduced; the rubber buffer pad and the bearing are of an integrated structure, interference fit does not exist between the bearing and the rubber buffer pad, the working clearance of the bearing can be effectively controlled, the service life is prolonged, the bearing is reliably fixed, and the bearing is prevented from being disengaged from the rubber buffer pad.

Description

technical field [0001] The invention relates to the field of intermediate bracket assemblies, in particular to a heavy-duty drive shaft intermediate bracket assembly in which rubber is vulcanized on the outer ring of a bearing. Background technique [0002] In the existing heavy-duty transmission shaft intermediate support assembly, the rubber buffer pad of the support is generally vulcanized on the outer circle of the bearing seat, and the inner circle of the bearing seat is assembled with the bearing, and the bearing is blocked and fixed by the left and right snap rings. This structure has the following disadvantages: [0003] 1. Parts processing and assembly are cumbersome. In the existing structure, the rubber pad needs to be vulcanized on the bearing seat first, and then the bearing is pressed into the bearing seat. After that, snap rings are installed on the left and right sides of the bearing to block the bearing. The bearing seat needs to be processed. Assemble bear...

AI Technical Summary

Problems solved by technology

[0003] 1. Parts processing and assembly are cumbersome. In the existing structure, the rubber pad needs to be vulcanized on the bearing seat first, and then the bearing is pressed into the bearing seat. Afterwards, snap rings are installed on the left and right sides of the bearing to block the bearing. The bearing seat needs to be processed. Assemble bearings and snap rings;

[0004] 2. The weight is heavy, the bearing seat is processed by steel thick-walled pipe lathe, and the parts are heavy;

[0005] 3. The cost is high. To assemble the bearing, one more bearing seat is required, and two snap rings total three parts
