Abstract

The utility model relates to a rolling bearing comprising a bearing body and a plurality of roller balls. The outer wall of the outer ring of the bearing body is provided with at least an annular shallow slot; accordingly, high molecular compound material ring which is a little convex to the independent outer side of the outer ring is embedded in each annular shallow slot, which forms integration. When the rolling bearing of the utility model is deformed under heating in work, the high molecular compound material ring expands; the rolling bearing is tightly attached to a hole of an outer shell, which can prevent the outer ring from moving and deforming; the bearing is easy to implement radial interference compensation in work; thus, the service life of the rolling bearing is improved.

Description

Rolling bearing with compensate function

The utility model relates to a kind of rolling bearing.

Rolling bearing in use tends to occur: occur looseningly between bearing outer ring and the shell aperture that cooperates, and then cause bearing or shell aperture infringement, to the shell aperture of light alloy material more so, can cause the motion inefficacy when serious.So existing rolling bearing is shorter working life.

Although cause the reason of foregoing problems a lot: bearing itself and shell aperture be expanded by heating at work, and heat distortion amount is inconsistent between the two, obviously is one of chief reason.

The purpose of this utility model is exactly in order to address the above problem, and a kind of rolling bearing with compensate function of long service life is provided.

Technical solution of the present utility model:

A kind of rolling bearing with compensate function, it includes bearing support and a plurality of ball, it is characterized in that on the outer ring outer wall of bearing support, having at least one annular shallow slot, correspondingly, the polymer composite ring of ring outer wall outside separately the summary of all splicing in each annular shallow slot is protruded, they are an integral body.

The utility model has the multiple tracks annular shallow slot first on the housing washer outer wall, correspondingly, the polymer composite ring of in each annular shallow slot, all having spliced, rolling bearing then of the present utility model, during temperature distortion, its polymer composite ring expands at work, fit tightly with shell aperture, can prevent the outer ring creeping deformation, make bearing realize the radial interference compensation at work expediently, thus the working life of improving rolling bearing.

Fig. 1 is a partial structurtes schematic representation of the present utility model.

As Fig. 1, the utility model includes the rolling bearing of being made up of bearing support 1 and a plurality of ball 2, characteristics of the present utility model are, on 3 outer walls of the outer ring of bearing support 1, have at least one annular shallow slot 4, correspondingly, the polymer composite ring 5 of outer ring 3 outer walls is protruded in separately the summary of all splicing in each annular shallow slot 4, and they are an integral body.

In the utility model, the quantity of the annular shallow slot 4 on 3 outer walls of bearing support 1 outer ring is decided with the bearing size as required, and it can be 1 road or 2 roads or 3 roads or multiple tracks.When rolling bearing of the present utility model is installed,, can be pressed in the shell aperture with a special mounting angle for guaranteeing not damage polymer composite ring 5.Because the external diameter of selected polymer composite ring 5 can be consistent in the larger context with the thermal expansion coefficient of the shell aperture internal diameter of light alloy, thereby when this bearing directly is pressed into bearing hole, rolling bearing is engaged in obtains interference, the working life of improving bearing effectively in the bigger scope.

Claims

1, a kind of rolling bearing with compensate function, it includes bearing support and a plurality of ball, it is characterized in that on the outer ring outer wall of bearing support, having at least one annular shallow slot, correspondingly, the polymer composite ring of ring outer wall outside separately the summary of all splicing in each annular shallow slot is protruded, they are an integral body.

2,, it is characterized in that quantity or 1 road or 2 roads or 3 roads of the annular shallow slot on the outer ring outer wall of bearing support by the described rolling bearing of claim 1 with compensate function.
