Description
Technical field
The utility model relates to a kind of high-cooling property rolling bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be 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.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
Rolling bearing is in use because therefore the High Rotation Speed of rolling element can distribute higher heat, after heat passes to drive motor by transmission shaft, damage can be caused to drive motor, simultaneously due to rolling element heating, retainer deliquescing can be caused, cause retainer to be out of shape, affect the normal use of bearing.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high-cooling property rolling bearing, and this device has higher thermal diffusivity, avoids heat to accumulate on rolling element, improves working life.
For solving the problem, the utility model adopts following technological scheme:
A kind of high-cooling property rolling bearing, comprise inner ring, outer ring, rolling element and retainer, it is inner that described inner ring is arranged on described outer ring, described inner ring and described outer ring are coaxially arranged, described rolling element is connected between described inner ring and outer ring, described rolling element annular is provided with more than five, described retainer connects described rolling element successively, the thickness of described outer ring is greater than inner ring thickness, the both sides of described outer ring are provided with a ladder surface, the front-end face of described outer ring is provided with the first dissipating cover, the ear end face of described outer ring is provided with the second dissipating cover, described first dissipating cover has the first radiating groove, described first radiating groove annular is arranged, the center position of described second dissipating cover is provided with the mounting hole relative with described inner ring, the surface of described second dissipating cover is provided with the second radiating groove, described second radiating groove annular is arranged.
As preferred technological scheme, described first radiating groove and the second radiating groove are V-shaped groove.
As preferred technological scheme, described first dissipating cover and the second dissipating cover are aluminum.
As preferred technological scheme, the internal surface of described mounting hole is provided with sealing gasket, forms the gap of a 0.1mm-0.2mm between described sealing gasket and transmission shaft, by arranging sealing gasket, oarse-grained dust can be avoided to enter into Bearing inner, wearing and tearing are caused to bearing.
The beneficial effects of the utility model are: this device has higher thermal diffusivity, heat is avoided to accumulate on rolling element, improve the working life of bearing, the structure of this device is comparatively simple simultaneously, install more for convenience, when the slow-speed of revolution, also can remove the first dissipating cover and the second dissipating cover, meet and use needs, be applicable to promoting the use of.
