Abstract
The utility model relates to the technical field of bearings, and in particular relates to a dustproof bearing. The dustproof bearing comprises a bearing which is provided with bumps and an upper cover, wherein the central part of the upper cover is provided with a bearing hole, grooves are formed in the upper cover, the size of the grooves is greater than that of the bumps, and at least two sets of grooves and bumps are arranged. According to the dustproof bearing used, the upper cover is additionally arranged on the bearing and is installed through the grooves and the bumps on the bearing and the upper cover during use, so that the upper cover is stably installed. Dust and impurities are prevented from entering the bearing, so that the bearing is normally used, and a using effect is good.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of shield bearing.
Background technique
The situation that bearing in use there will be dust impurity to enter bearing inside, have no idea at present to prevent that dust impurity from entering bearing inside, will cause like this bearing minimizing in working life.
The model utility content
The deficiency that in order to overcome existing dust impurity, can enter bearing, the utility model provides a kind of shield bearing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of shield bearing, comprise bearing, described bearing is provided with projection, described bearing is provided with upper cover, described upper cover core is bearing hole, cover on described and be provided with groove, the size of described groove is greater than the size of projection, and described groove is at least 2 groups than the number of projection.
The beneficial effects of the utility model are, this shield bearing increases a upper cover when in use on bearing, utilize bearing and on the groove and the projection that cover install, the installation that guarantees upper cover is stable, and can completely cut off dust impurity and enter bearing, the use that guarantees bearing is normal, and using effect is good.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is upper cover schematic diagram of the present utility model;
Fig. 3 is bearing plan view of the present utility model;
Fig. 4 is upper cover plan view of the present utility model;
In figure 1, bearing, 2, projection, 3, upper cover, 4, bearing hole, 5, groove.
Embodiment
Structural representation of the present utility model as Fig. 1, a kind of shield bearing, comprise bearing 1, described bearing 1 is provided with projection 2, described bearing 1 is provided with upper cover 3, and described upper cover 3 cores are bearing hole 4, and described upper cover 3 is provided with groove 5, the size of described groove 5 is greater than the size of projection 2, and described groove 5 is at least 2 groups than the number of projection 2.
This shield bearing is installed a upper cover 3 above bearing 1, and projection 2 is installed on bearing 1, and groove 5 is installed on upper cover 3, and groove 5 and projection 2 corresponding positions are installed, and the size of groove 5 is slightly larger than projection 2, so just upper cover 3 can be arranged on bearing 1, and upper cover 3 not there will be rotation, so just can guarantee can not enter bearing inside in bearing 1, guarantee the normal use of bearing 1.
