Abstract

The utility model relates to the automobile air conditioner motor technology field, and specifically relates to a bearing vibration damping sleeve device used for an automobile air conditioner motor. The bearing vibration damping sleeve device comprises a bearing and a motor end cover, the bearing is sleeved with the motor end cover, a bearing vibration damping sleeve is disposed between the bearing and the motor end cover, the bearing vibration damping sleeve is combined with a radial vibration damping body and an axial vibration damping body, and the bearing vibration damping sleeve is prepared by high-quality silica gel materials. External shocks are buffered by installing the bearing vibration damping sleeve, prepared by the silica gel materials, between the bearing and the motor end cover, so that vibration damping effect is achieved, and the bearing vibration damping sleeve is simple in structure and convenient to install.

Description

A kind of for the bearing shock-reducing sleeve device on automobile air conditioner motor

Technical field

The utility model relates to automobile air conditioner motor technical field, is specifically related to a kind of for the bearing shock-reducing sleeve device on automobile air conditioner motor.

Background technology

At present, be all furnished with air-conditioning in nearly all automobile, and the most indispensablely in air-conditioning be and be motor, the quality of motor quality is directly connected to the normal operation of air-conditioning.Automobile most of the time of turning on the aircondition is all to exercise in way at vehicle, particularly in summer, turn on the aircondition and become a kind of custom of people, when Vehicle Driving Cycle, easily be subject to that external environment condition is poor, the large life-span that directly affects motor bearings of vibration, and the automobile air conditioner motor of current production exist between shock-reducing sleeve and bearing exist the middle radial error that runs up for a long time large, cause bearing clearance serious wear, make bearing nearly all have poor problem of a life-span, and this problem, be also the very large challenge that a lot of air conditioner motor manufacturers face.

Chinese patent Granted publication number: CN 202719136 U, a kind of motor bearings sealing shroud is disclosed, comprise the sealing shroud body being embedded in electric motor end cap upper bearing (metal) hole, sealing shroud body is tubular, in it, be provided with for bearings mounted cavity, sealing shroud body one end extends to form sealing ring to center around, the surface laminating of the inner hole wall of sealing ring and rotor output shaft.In electric machine rotation process; sealing shroud body has shock-absorbing and reduces the effect of noise; the dust in motor outside, steam all can keep off and cannot enter motor internal by sealed loop resistance simultaneously; thereby effectively protect motor, improve the useful life of motor, though this kind of sealing shroud can shock-absorbing play good effect with minimizing noise; but in permanent running at a high speed; owing to being subject to environment and self impact, tend to occur bearing clearance serious wear phenomenon, also can cause the poor problem of bearing life.

Summary of the invention

The utility model is in order to overcome the problems referred to above, provides a kind of simple in structure, good stability and for the bearing shock-reducing sleeve device on automobile air conditioner motor.

In order to achieve the above object, it is a kind of for the bearing shock-reducing sleeve device on automobile air conditioner motor that the utility model provides, comprise bearing and electric motor end cap, described bearing outside has electric motor end cap, between described bearing and electric motor end cap, be provided with bearing shock-reducing sleeve, described bearing shock-reducing sleeve is made by radial vibration-reducing body and axial vibration damping body respectively.

In order effectively to prevent bearing clearance wearing and tearing, the silica gel material that described bearing shock-reducing sleeve adopts is made.

The utility model beneficial effect is: by a bearing shock-reducing sleeve of being made by silica gel material is installed between bearing and electric motor end cap, cushion extraneous impact, thereby reach effectiveness in vibration suppression, and this bearing shock-reducing sleeve is simple in structure, easy for installation.

Accompanying drawing explanation

Fig. 1 is that the master for the bearing shock-reducing sleeve device on automobile air conditioner motor described in the utility model looks cutaway view;

Fig. 2 is that the structure of bearing shock-reducing sleeve described in the utility model is looked intention;

In figure: 1-radial vibration-reducing body, 2-axial vibration damping body, 3-bearing shock-reducing sleeve, 4-electric motor end cap, 5-bearing.

Embodiment

As shown in Figure 1, 2, a kind of for the bearing shock-reducing sleeve device on automobile air conditioner motor, comprise bearing 5 and electric motor end cap 4, described bearing 5 overcoats have electric motor end cap 4, and be provided with bearing shock-reducing sleeve 3 between bearing 5 and electric motor end cap 4, described bearing shock-reducing sleeve 3 is made by radial vibration-reducing body 1 and axial vibration damping body 2 respectively, and described radial vibration-reducing body 1 closely cooperates with dead eye inner cylinder face, bearing 5 external cylindrical surfaces respectively; Axial vibration damping body 2 closely cooperates with dead eye inner face, bearing face respectively, and the silica gel material that bearing shock-reducing sleeve 3 adopts is made, by the 1 buffering radial vibration of radial vibration-reducing body, axial vibration damping body 2 cushions axial vibrations, thereby reaches the damping effect of motor like this.

Claims

1. one kind for the bearing shock-reducing sleeve device on automobile air conditioner motor, comprise bearing and electric motor end cap, described bearing outside has electric motor end cap, it is characterized in that: between described bearing and electric motor end cap, be provided with bearing shock-reducing sleeve, described bearing shock-reducing sleeve is made by radial vibration-reducing body and axial vibration damping body respectively.

2. the bearing shock-reducing sleeve device on automobile air conditioner motor according to claim 1, is characterized in that: the silica gel material that described bearing shock-reducing sleeve adopts is made.
