Abstract
The utility model relates to a kind of macropore thin-wall bearing, comprise bearing outer ring, bearing inner race, retainer, steel ball, described retainer is arranged between bearing outer ring and bearing inner race, described steel ball is arranged in the mounting hole of retainer, described mounting hole is coated with wearing layer with contacting on wall of steel ball, and the quantity of described steel ball is 20-25.The steel ball quantity of this macropore thin-wall bearing is 20-25, make bearing inner race and bearing outer ring substantially in completely spherical state, bearing capacity is strong, contacting of mounting hole and steel ball is coated with wearing layer on wall, can not cause the mounting hole of retainer to become large because bearing uses for a long time, there is the phenomenon that steel ball rocks, extended the working life of bearing.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of macropore thin-wall bearing.
Background technique
Thin-wall bearing precision is high, very quiet and bearing capacity is very strong, the bearing capacity of existing macropore thin-wall bearing is inadequate on the market, and use after a period of time at bearing, there will be retainer and steel ball to cause wearing and tearing because of transition friction, have a strong impact on the working life of thin-wall bearing.
Model utility content
The purpose of this utility model is in order to solve the existing defect of thin-wall bearing in prior art, to provide a kind of bearing capacity strong, the macropore thin-wall bearing of long service life.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of macropore thin-wall bearing, comprise bearing outer ring, bearing inner race, retainer, steel ball, described retainer is arranged between bearing outer ring and bearing inner race, described steel ball is arranged in the mounting hole of retainer, described mounting hole is coated with wearing layer with contacting on wall of steel ball, and the quantity of described steel ball is 20-25.
Above-mentioned a kind of macropore thin-wall bearing, described wearing layer is chromium coating.
Above-mentioned a kind of macropore thin-wall bearing, described wearing layer is steel plating layer.
Above-mentioned a kind of macropore thin-wall bearing, is equipped with oil resistant rubber layer on the inwall of described bearing outer ring, the outer wall of bearing inner race.
The beneficial effects of the utility model are: the steel ball quantity of this macropore thin-wall bearing is 20-25, make bearing inner race and bearing outer ring substantially in completely spherical state, bearing capacity is strong, contacting of mounting hole and steel ball is coated with wearing layer on wall, can not cause the mounting hole of retainer to become large because bearing uses for a long time, there is the phenomenon that steel ball rocks, extended the working life of bearing.
Brief description of the drawings
Fig. 1 is explosive view of the present utility model;
Fig. 2 is ssembly drawing of the present utility model.
Embodiment
For making that structure characteristic of the present utility model and effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1 and Figure 2, a kind of macropore thin-wall bearing, comprise bearing outer ring 1, bearing inner race 2, retainer 3, steel ball 4, retainer 3 is arranged between bearing outer ring 1 and bearing inner race 2, steel ball 4 is arranged in the mounting hole 5 of retainer 3, as improvement of the present utility model, mounting hole 5 is coated with wearing layer 6 with contacting on wall of steel ball 4, and the quantity of steel ball is 20-25.
In the utility model, wearing layer 6 is preferably chromium coating or steel plating layer.
Further, on the outer wall of the inwall of bearing outer ring 1, bearing inner race 2, be equipped with oil resistant rubber layer, in lubricated process, reduce the corrosion of lubricant oil to bearing outer ring 1 and bearing inner race 2.
The steel ball quantity of this macropore thin-wall bearing is 20-25, make bearing inner race 2 and bearing outer ring 1 substantially in completely spherical state, bearing capacity is strong, contacting of mounting hole 5 and steel ball 4 is coated with wearing layer 6 on wall, can not cause the mounting hole 5 of retainer to become large because bearing uses for a long time, there is the phenomenon that steel ball 4 rocks, extended the working life of bearing.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
