Abstract

The utility model discloses an outer ring integrated tensioning wheel bearing for an automobile, which comprises a bearing outer ring (1), an inner ring (2), steel balls (3), a sealing element (4) and a retainer (5), wherein the bearing outer ring is sleeved on the inner ring through the steel balls and the retainer, and the sealing element is arranged between the bearing inner ring and the outer ring. The outer ring integrated tensioning wheel bearing for the automobile is characterized in that a shell is accommodated in the bearing outer ring to be integrated into a whole. The outer ring integrated tensioning wheel bearing for the automobile has a compact structural design; and the shell design is canceled, the bearing outer ring is designed to be of a shell shape, thus the influence of the matching of the shell and the bearing outer ring to a bearing backlash and a breakaway force between the shell and the bearing outer ring is avoided, and the shaking of the belt in an operating process is reduced, and the service life of the tensioning wheel bearing is prolonged.

Description

A kind of outer ring all-in-one car tension wheel shaft bearing

Technical field

The utility model relates to a kind of automobile tension wheel shaft bearing.

Background technique

The automobile tension wheel shaft bearing is as one of important accessory of motor, at present being widely used progressively.Its main effect is exactly the tension force that keeps belt, thereby makes the more effective work of motor.But; The usability of the automobile tension wheel shaft bearing on the existing market is not good, particularly uses being connected of standard rolling bearing outer ring and shell, directly influences the play of tension wheel shaft bearing assembling and pulling-out force between the two; If play does not have the bearing stuck phenomenon to occur; Traffic safety is brought very big potential safety hazard,, the phenomenon of bearing outer ring and shell slide relative will occur if pulling-out force between the two is too little; And the cooperation of standard rolling bearing outer ring and shell also makes the end face run-out of tension wheel shaft bearing increase, and increased the wearing and tearing of belt and the noise of motor simultaneously.

Summary of the invention

The utility model technical problem to be solved has provided the automobile tension wheel shaft bearing that a kind of compact structure, outer ring are integrated, avoid occurring the stuck and slide relative phenomenon of bearing.

A kind of outer ring all-in-one car tension wheel shaft bearing comprises bearing outer ring, inner ring, steel ball, Sealing and retainer.Bearing outer ring is provided with Sealing through steel ball, retainer and inner ring socket between bearing inner race and outer ring, it is characterized in that bearing outer ring comprises shell and becomes one.This structural design is compact; Cancelled design of shell, bearing outer ring is designed to shell shape, has avoided cooperating bearing clearance and the influence of pulling-out force between the two of shell and bearing outer ring; Simultaneously also alleviate belt rocking in the course of the work, prolonged the working life of tension wheel shaft bearing.
