Abstract

The utility model relates to a non-directional roller bearing which is characterized by comprising a shell, an outer ring and an inner ring. The outer ring is mounted in the shell through a clamp spring, the inner ring is mounted in the outer ring, the inner surface of the outer ring is of a concave spherical structure, and the outer surface of the inner ring is of a convex spherical structure embedded to the concave spherical structure of the outer ring. The outer surface of the inner ring is connected with the inner surface of the outer ring through a universal structure, so that the outer ring and the shell are changed along with rails of a fork arm carrier of a forklift when a bearing shaft mounted on the inner ring is fixed, and damage of the bearing is avoided.

Description

A kind of non-directional roller bearing

Technical field

The utility model relates to a kind of roller bearing, particularly a kind of non-directional roller bearing.

Background technique

The car goods shelf is in the lateral translation process of the left and right sides, because the restriction of unbalance loading or machining accuracy aspect, the translation of goods shelf often can not remain on a parallel position with the axis of bearing, often causes bearing in use to lose efficacy prematurely and damages.

Summary of the invention

The technical problem that the utility model will solve provides a kind of non-directional roller bearing of long service life.

For solving the problems of the technologies described above; The technological scheme of the utility model is: a kind of non-directional roller bearing; Its innovative point is: comprise shell, outer ring and inner ring, through jump ring the outer ring is installed in the said shell, in the said outer ring inner ring is installed; The internal surface of said outer ring is the concave spherical surface structure, and said inner ring outer surface is the protruding spheric structure with outer ring concave spherical surface structure tabling.

The advantage of the utility model is: the inner ring outer surface for the protruding spheric structure of outer ring concave spherical surface structure tabling; Both connect through universal structure; Make and to be installed in bearing shaft on the inner ring under the situation of fixed-site; Realize that outer ring, shell change with the track of fork of forklift truck frame, avoid the damage of bearing.

Description of drawings

Fig. 1 is the utility model non-directional roller bearing structural representation.

Embodiment

As shown in Figure 1, comprise shell 1, outer ring 2 and inner ring 3, through jump ring 4 outer ring 2 is installed in the shell 1, inner ring 3 is installed in the outer ring 2.

Outer ring 2 with the concrete link structure of inner ring 3 is: the internal surface of outer ring 2 is the concave spherical surface structure, and inner ring 3 outer surfaces are the protruding spheric structure with outer ring 2 concave spherical surface structure tablings.Both constitute universal linkage structure, make to be installed in bearing shaft on the inner ring 3 under the situation of fixed-site, realize that outer ring 2, shell 1 change with the track of fork of forklift truck frame, avoid the damage of bearing.

Claims

1. non-directional roller bearing; It is characterized in that: comprise shell, outer ring and inner ring; Through jump ring the outer ring is installed in the said shell; In the said outer ring inner ring is installed, the internal surface of said outer ring is the concave spherical surface structure, and said inner ring outer surface is the protruding spheric structure with outer ring concave spherical surface structure tabling.
