Abstract

The utility model relates to the technical field of bearings, in particular to an inwards-concave roller bearing. The inwards-concave roller bearing comprises a bearing, wherein a retainer is arranged in the bearing; a roller is arranged on the retainer; and the shape of the retainer is inwards concave. According to the inwards-concave roller bearing, the retainer is designed to be inwards concave, and during mounting, through elasticity of the retainer, the roller bearing is quickly and conveniently arranged on at a position requiring mounting, and has a good using effect.

Description

The concave roller bearing
Technical field
The utility model relates to technical field of bearings, especially a kind of concave roller bearing.
Background technique
Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Present roller bearing mostly is greatly plane type, and trouble is installed, and working efficiency is low.
The model utility content
The deficiency of trouble is installed in order to overcome existing roller bearing, and the utility model provides a kind of concave roller bearing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of concave roller bearing, comprise bearing, and be provided with retainer in the described bearing, described retainer is provided with roller, and the shape of described retainer concaves.
The beneficial effects of the utility model are, this concave roller bearing is designed to concave with retainer, when installing, utilize the elasticity of retainer, and roller bearing is installed in needs the position of installing, and rapid and convenient is installed, and using effect is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Among the figure 1, bearing, 2, retainer, 3, roller.
Embodiment
Be structural representation of the present utility model such as Fig. 1, a kind of concave roller bearing comprises bearing 1, is provided with retainer 2 in the described bearing 1, and described retainer 2 is provided with roller 3, and the shape of described retainer 2 concaves.
This concave roller bearing is designed to concave with retainer 2, roller 3 is installed on the retainer 2, when bearing 1 is installed, utilize the elasticity of retainer 2 self, bearing 1 is installed in the position that needs installation, the installation process rapid and convenient, using effect is good.
