Abstract
The utility model discloses a novel bearing inner ring, belonging to the technical field of a bearing inner ring. The novel bearing inner ring comprises an inner ring body provided with a dustproof groove on the outer wall. The dustproof groove comprises a round table face and a cylindrical face, wherein the upper bottom face of the round table face is in butt joint with the cylindrical face in a matching manner; and the lower bottom face of the round table face is in butt joint with the outer wall of the inner ring body. According to the novel bearing inner ring provided by the utility model, the structure of the dustproof groove is improved, so that not only can the novel bearing inner ring be convenient to machine, but also a sealing ring cannot be cut. Therefore, the service life of the sealing ring is prolonged.
Description
Technical field
The utility model discloses a kind of novel bearing inner ring, belongs to the technical field of bearing inner race.
Background technique
All offer dustproof groove on the outer wall of bearing inner race, be used to install seal ring.Existing dustproof groove is mainly concave groove 1 structure, sees accompanying drawing 1 for details.In actual production and using, the not only difficult processing of the dustproof groove of this structure, and be easy to generate sawtooth, and the phenomenon of often appearance incised wound seal ring, thus seal ring was lost efficacy.
Summary of the invention
For addressing the above problem, it is a kind of easy to process that the utility model provides, and can not hurt the novel bearing inner ring of seal ring again.
For realizing above-mentioned purpose, the technological scheme that the utility model adopted is:
A kind of novel bearing inner ring comprises the inner ring body that offers dustproof groove on the outer wall, and said dustproof groove comprises round table surface, cylndrical surface, and wherein the upper bottom surface of round table surface cooperates butt joint with the cylndrical surface, and the bottom surface of round table surface cooperates butt joint with inner ring body outer wall.
A kind of novel bearing inner ring of the utility model has improved the structure of dustproof groove, has not only made things convenient for processing, and can not hurt seal ring, prolongs the working life of seal ring.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of existing bearing inner race;
Fig. 2 is the structural representation of the utility model.
