Abstract
The utility model provides a cylindrical roller bearing capable of improving the lubricating property of the bearing. The cylindrical roller bearing comprises a bearing inner ring, a bearing outer ring, a cylindrical roller and a holder, wherein a corresponding cylindrical roller groove is arranged on the bearing inner ring or the bearing outer ring, and the cylindrical roller is arranged in the cylindrical roller groove arranged on the bearing inner ring or the bearing outer ring. The cylindrical roller bearing is characterized in that the holder is the holder capable of improving the lubricating property, the periphery of a pocket hole of the holder is provided with an arc groove, the arc groove is stored with lubricating agent, and the lubricating agent is directly contacted with the outer diameter and the end face of the cylindrical roller bearing, so that the lubricating effect of the bearing can be improved. Within the maintenance period of the bearing, the arc groove is always stored with the lubricating agent. According to the cylindrical roller bearing, the lubricating effect of the bearing can be improved.
Description
Technical field
The utility model relates to a kind of roller bearing, particularly discloses a kind of roller bearing that improves the bearing lubrication performance.
Background technique
Roller bearing generally is comprised of the outer ring of bearing, inner ring, cylindrical roller and the retainer of bearing.Bearing inner race band rib or two kinds of structures of bearing outer ring band rib are wherein arranged, and in the process of bearing operation, the end face of cylindrical roller contacts with the rib of lasso, is more difficult at this separate lubrication, and this situation easily causes the inefficacy of bearing.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and the handling characteristics of comprehensive roller bearing discloses a kind of roller bearing that improves the bearing lubrication performance.The surrounding of the utility model in the retainer pocket hole of roller bearing is designed with the arc groove of kind of lubricant storage, by design of the present utility model, realizes directly lubricated cylindrical roller of oiling agent, reaches the effect that improves the bearing lubrication performance.
the utility model is achieved in that a kind of roller bearing that improves the bearing lubrication performance, comprise bearing inner race, bearing outer ring, cylindrical roller and retainer, be provided with corresponding cylindrical roller groove on bearing inner race or bearing outer ring, cylindrical roller is placed in the cylindrical roller groove of bearing inner race or bearing outer ring, it is characterized in that: described retainer is for improving the retainer of bearing lubrication performance, the pocket hole surrounding of retainer has arc groove, described arc groove stores oiling agent, described oiling agent directly and external diameter and the end contact of cylindrical roller, and then the lubrication effect of raising bearing.In maintenance period, store all the time oiling agent at bearing in described arc groove.
The beneficial effects of the utility model are: the utility model utilizes the arc groove kind of lubricant storage of retainer pocket hole surrounding to guarantee that bearing lubricant directly contacts with cylindrical roller, and then the lubrication effect of raising bearing.
