Abstract

The utility model relates to an articulated bearing, which comprises an inner ring and an outer ring, wherein the spherical outside surface of the inner ring is convexly arc; the middle upper part of the inner wall of the outer ring is a concavely arc spherical inside surface; the spherical inside surface is suitable for being matched with the spherical outside surface; the lower part of the inner wall of the outer ring is linear; and the spherical inside surface and the spherical outside surface are subjected to phosphorization treatment. The articulated bearing is simple in structure, and by adoption of the special structure, the articulated bearing has the advantages of a radial spherical plain bearing and an angular-contact articulated bearing, so that the bearing can bear a radial load and axial loads in any direction.

Description

A kind of joint shaft bearing

Technical field

The utility model relates to a kind of joint shaft bearing.

Background technique

Joint shaft bearing mainly is comprised of inner ring and the outer ring by inner ball surface by outer spherical surface, can bear larger load; Joint shaft bearing can be divided into plain radial bearing, angular contact articulated bearing, thrust articulated bearing, spherical plain bearing rod end etc., plain radial bearing can bear radial load and the less thrust load of either direction, and angular contact articulated bearing can bear radial load and a direction thrust load.

The model utility content

Technical problem to be solved in the utility model provide a kind of simple in structure, possess the joint shaft bearing of the advantage of plain radial bearing and angular contact articulated bearing simultaneously.

In order to address the above problem, the utility model provides a kind of joint shaft bearing, comprising: inner ring 1 and outer ring 2; The outer spherical surface of inner ring 1 is convex, and the middle and upper part of outer ring 2 inwalls is the inner ball surface of concave arc shape; Described inner ball surface is suitable for matching with outer spherical surface, and the bottom of described outer ring 2 inwalls is shape linearly.Described internal and external spherical surfaces adopts phosphatization to process, and makes to have good lubricity between the sphere.

The utility model has positive effect with respect to prior art: joint shaft bearing of the present utility model is simple in structure, the special structure of employing makes this joint shaft bearing have simultaneously the advantage of plain radial bearing and angular contact articulated bearing, makes this bearing can bear radial load and either direction thrust load.

Description of drawings

For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein:

Fig. 1 is the structural drawing of joint shaft bearing of the present utility model.

Embodiment

See Fig. 1, the joint shaft bearing of present embodiment comprises: inner ring 1 and outer ring 2; The outer spherical surface of inner ring 1 is convex, and the middle and upper part of outer ring 2 inwalls is the inner ball surface of concave arc shape; Described inner ball surface is suitable for matching with outer spherical surface, and the bottom of described outer ring 2 inwalls is shape linearly.Described internal and external spherical surfaces adopts phosphatization to process, and makes to have good lubricity between the sphere.

Joint shaft bearing of the present utility model adopts special structure to make this joint shaft bearing have simultaneously the advantage of plain radial bearing and angular contact articulated bearing, makes this bearing can bear radial load and either direction thrust load.

Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.

Claims

1. a joint shaft bearing is characterized in that comprising: inner ring and outer ring; The outer spherical surface of inner ring is convex, and the middle and upper part of outer ring inwall is the inner ball surface of concave arc shape; Described inner ball surface is suitable for matching with outer spherical surface; Described internal and external spherical surfaces adopts phosphatization to process.
