Problems solved by technology

[0002] At present, the elastic rubber bearings used in traditional automobile steering gears have no restrictions on the end face of the cage assembly due to the cylindrical structure of the elastic ring. This structure has a failure mode in which individual cages are deformed or damaged by force during assembly. Due to improper operation or irregular chamfering of the shaft, there will also be problems such as the detachment of the cage assembly, which will lead to rework or scrap of the steering gear

Abstract

The invention discloses a dual-flange outer ring elastic rubber bearing which comprises a rubber cover and a framework embedded to the outer ring of the rubber cover, wherein an elastic ring is arranged in the rubber cover, a retainer assembly is arranged in the elastic ring, the retainer assembly comprises a plastic retainer and a needle roller, two sides of the elastic ring are provided with flanges, and the flanges are of annular flange structures. According to the manner, the elastic bearing can achieve the effect that the plastic retainer assembly is protected from falling-off and damage during assembly and bearing installation since the retainer assembly is held in the elastic ring, thus optimizing the process and installation performances of products.

Description

technical field [0001] The invention relates to the technical field of steering gear bearings, in particular to an elastic rubber bearing with double-rib outer rings for automobile steering gears. Background technique [0002] At present, the elastic rubber bearings used in traditional automobile steering gears have no restrictions on the end face of the cage assembly due to the cylindrical structure of the elastic ring. This structure has a failure mode in which individual cages are deformed or damaged by force during assembly. Due to improper operation or irregular chamfering of the shaft, there will also be problems such as the detachment of the cage assembly, which will lead to rework or scrap of the steering gear. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a double-rib outer ring elastic rubber bearing, which can protect the cage from being damaged and fall off, and reduce the scrap rate in the assembl...
