Abstract
The invention discloses a rubber bearing. The rubber bearing comprises a metal bearing sleeve and a rubber bush arranged inside the metal bearing sleeve, wherein dropping-preventing convex strips which are radially embedded into the rubber bush are arranged on the inner wall of the metal bearing sleeve. When the rubber bearing works, the arranged dropping-preventing convex strips can supply a circumferential thrust to the rubber bush, so that a circumferential friction force exerted by a rotating shaft onto the rubber bush can be counteracted, a relative movement trend between the rubber bush and the metal bearing sleeve can be avoided, a static friction force between the rubber bush and the metal bearing sleeve can be reduced, and accordingly, the problem that a rubber liner drops off under the action of a force in the using process is avoided; the rubber bush consists of four arc-shaped lining tiles, and when the rubber liner is expanded by heat in the working process, expansion clearances can accommodate expansion amounts of the lining tiles, so that the clearance between the rubber bush and the rotating shaft can be maintained, and increase of the friction force and aggravation of wearing between the rubber bush and the rotating shaft are prevented.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of rubber bush bearing.
Background technique
Rubber bush bearing take rubber as the bearing of main member, in order to play a supportive role to axle.Rubber bush bearing of the prior art, generally make one by bonding or hot melting way, but this Placement reliability is poor, in use easily occurs the problem of elastometric lining loose or dislocation between its elastometric lining and metal outer ring.
Summary of the invention
In view of this, the object of this invention is to provide a kind of rubber bush bearing, hold caducous problem to solve elastometric lining in existing rubber bush bearing.
Rubber bush bearing of the present invention, comprises metal shaft bearing sleeve and is arranged on the rubber bushing in metal shaft bearing sleeve, described metal shaft bearing sleeve inwall is provided with the anticreep raised line be radially embedded in rubber bushing.
Further, described rubber bushing is made up of pintongs arc lining tile, is provided with clearance for expansion between adjacent lining tile.
Further, the inwall of described rubber bushing is provided with spiral groove.
Beneficial effect of the present invention:
1, rubber bush bearing of the present invention, its anticreep raised line arranged operationally can provide the thrust of circumferencial direction to rubber bushing, thus the frictional force of rotating shaft to the circumferencial direction that rubber bushing applies can be offset, avoid the trend producing relative movement between rubber bushing and metal shaft bearing sleeve, reduce stiction between the two, thus eliminate the elastometric lining in use stressed problem come off.
2, rubber bush bearing of the present invention, its rubber bushing is made up of pintongs arc lining tile, in elastometric lining working procedure during expanded by heating, clearance for expansion can hold the swell increment of lining tile, thus the gap value between rubber bushing and rotating shaft can be kept, prevent frictional force between rubber bushing and rotating shaft from strengthening, wear and tear and aggravate.
Accompanying drawing explanation
Fig. 1 is the plan view of rubber bush bearing of the present invention;
Fig. 2 is the sectional view of Fig. 1 along A-A.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment rubber bush bearing, the rubber bushing 2 comprising metal shaft bearing sleeve 1 and be arranged in metal shaft bearing sleeve, described metal shaft bearing sleeve inwall is provided with the anticreep raised line 3 be radially embedded in rubber bushing.
The present embodiment rubber bush bearing, its anticreep raised line arranged operationally can provide the thrust of circumferencial direction to rubber bushing, thus the frictional force of rotating shaft to the circumferencial direction that rubber bushing applies can be offset, avoid the trend producing relative movement between rubber bushing and metal shaft bearing sleeve, reduce stiction between the two, thus eliminate the elastometric lining in use stressed problem come off.
As the improvement to the present embodiment, described rubber bushing is made up of pintongs arc lining tile, is provided with clearance for expansion 4 between adjacent lining tile.
The present embodiment rubber bush bearing, its rubber bushing is made up of pintongs arc lining tile, in elastometric lining working procedure during expanded by heating, clearance for expansion can hold the swell increment of lining tile, thus the gap value between rubber bushing and rotating shaft can be kept, prevent frictional force between rubber bushing and rotating shaft from strengthening, wear and tear and aggravate.
As the improvement to the present embodiment, the inwall of described rubber bushing is provided with spiral groove 5, can be lubricated by countershaft by spiral groove 5 comprehensively, effectively can reduce the frictional heat between rubber bushing and rotating shaft and wearing and tearing, be conducive to the long-range rubber bushing life-span.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
Claims (3)
