Abstract
The invention relates to a ball bearing with good heat dissipation performance and belongs to the technical field of bearings. The ball bearing comprises an inner ring, balls, a cage and an outer ring. The balls are hollow and are disposed at intervals. The cage comprises a ring type upper frame and positioning blocks evenly disposed at the lower end of the upper frame. The bottoms of the positioning blocks are concave to form grooves matched with the balls. The positioning blocks are provided with hemispheric concave surfaces. The outer ring is hollow. The inner surface of the outer ring is provided with an outer ball track. The lower part of the outer ball track is provided with a flange. The outer ring sleeves the inner ring. The balls are arranged between the outer ball track and an inner ball track and are embedded in the grooves of the positioning blocks. The cage is disposed between the outer ball track and the inner ball track. The ball bearing is simple, compact and reasonable in structure, rapid and convenient to assemble, reliable in connection, low in mass and thermal capacity, and capable of avoiding a ball bearing seizure phenomenon, reducing frictional force of machines and prolonging the service lifetime of the bearing.

Background technique
Bearing rises fixing in mechanical transmission course and reduces the parts of load friction factor, alternatively, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.
Existing ball bearing mass ratio is heavier, and ratio of heat capacities is comparatively large, the phenomenon that ball bearing is killed easily occurs, improves the frictional force of machinery, shorten the working life of ball bearing, greatly reduce the reliability of ball bearing work.
In view of this, the present inventor develops a kind of ball bearing of good heat dissipation specially, and this case produces thus.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect mentioned and deficiency, and a kind of ball bearing of good heat dissipation is provided.
The technological scheme that the present invention realizes the employing of its object is as follows.
A ball bearing for good heat dissipation, comprises inner ring, ball, supporting frame and outer ring;
Described inner ring comprises pedestal and the cylinder of concentric setting; Described pedestal is arranged on the upper-end surface of cylinder; Described cylindrical hollow is arranged, and the outer side surface of cylinder is provided with interior raceway;
Described ball is hollow shape; And described ball interval is arranged;
Support frame as described above comprises in circular upper frame and the positioning block being distributed on upper frame lower end; Bottom described positioning block, indent forms the groove adapted with ball; Described positioning block has hemispherical concave surface;
Described outer ring hollow is arranged, and the internal surface of outer ring is provided with outer raceway;
Flange is provided with below described outer raceway; Described outer ring sleeve is located at inner ring outside; Described ball is arranged between outer raceway and interior raceway; Support frame as described above is arranged between outer raceway and interior raceway, and ball is embedded at the groove of positioning block.
Described pedestal radial equipartition has washer; Described washer interval is arranged; The base diameter of washer is less than the internal diameter of outer ring; The top diameter of washer is greater than the internal diameter of outer ring.
Described positioning block interval is arranged, and the spacing of adjacent positioned block is greater than the diameter of ball.
After adopting such scheme, this ball bearing structure is simple, compact and reasonable, fast easy to assembly, connect reliable, quality and thermal capacity little, can avoid occurring the phenomenon that ball bearing is killed, reduce the frictional force of machinery, extend the working life of bearing, substantially increase the reliability of bearing working, be easy to use and promote.
