Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] As shown in the figure, the rubber bearing of this embodiment includes a metal bearing sleeve 1 and a rubber bushing 2 arranged in the metal bearing sleeve. Convex 3.

[0014] In the rubber bearing of this embodiment, the anti-loosening protruding strips provided can provide the rubber bushing with a thrust in the circumferential direction during operation, thereby offsetting the frictional force exerted by the rotating shaft on the rubber bushing in the circumferential direction, and avoiding the friction between the rubber bushing and the metal bearing. There is a tendency of relative movement between the sleeves, which reduces the static friction between the two, thereby eliminating the problem that the rubber lining falls off under force during use.

[0015] As an improvement to this embodiment, the rubber bushing is composed of four-lobed a...

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 [0001] The invention relates to a bearing, in particular to a rubber bearing. Background technique [0002] Rubber bearings are bearings with rubber as the main component to support the shaft. In the rubber bearings in the prior art, the rubber lining and the metal outer ring are generally made into one by bonding or hot-melting, but this connection method is less reliable, and the rubber lining is prone to loosening during use. Shedding problem. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a rubber bearing to solve the problem that the rubber inner lining in the existing rubber bearing is easy to fall off. [0004] The rubber bearing of the present invention comprises a metal bearing sleeve and a rubber bush arranged in the metal bearing sleeve, and the inner wall of the metal bearing sleeve is provided with anti-loosening protrusions embedded in the rubber bush in the radial direction.
