Abstract
The utility model discloses a ceramic bearing, including bearing inner race, bearing inner race, cage and roller, the bearing inner race inner wall is inlayed has ceramic raceway, and bearing inner race is made by ceramic material, and the roller comprises hollow cylinder roller and ceramic roller shell. The utility model provides a through inlaying ceramic raceway at the bearing inner race inner wall, the roller adopts the structure of compriseing hollow cylinder roller and ceramic roller shell, holder and bearing inner race adopt ceramic material to make, can realize the corrosion resistance of bearing under high A corrosive environment, and the service life of the bearing is extended, can restrain the increase of the roller load that arouses because of the centrifugal force effect in addition and skid when high -speed rotatory, the mechanism that roller adoption hollow rollers and ceramic roller sleeve combined together, the weight of roller has been reduced, centrifugal action to bearing inner race when consequently rotating can reduce, and then life prolongs greatly.
Description
Technical field
The utility model belongs to technical field of bearings, is specifically related to a kind of ceramic bearing.
Background technique
Bearing is that mechanical industry uses extensively, requires strict auxiliary equipment and basic part, the joint of machinery is called by people, using scope is extensive, usual bearing material mostly is structure of steel product, the Environmental Conditions of bearing is various, is especially being covered with the mal-condition of Korrosionsmedium, and the material bearing of structure of steel product easily corrodes, produce and damage point, shorten the working life of bearing.
Model utility content
For problems of the prior art, the purpose of this utility model is to provide a kind of ceramic bearing.
The utility model is realized by the following technical programs: described a kind of ceramic bearing, comprise bearing outer ring, bearing inner race, retainer and roller, it is characterized in that, described bearing outer ring inwall is inlaid with ceramic raceway, described bearing inner race is made up of stupalith, and described roller is made up of hollow cylinder roller and ceramic roller shell.
Described a kind of ceramic bearing, is characterized in that, described retainer is made up of stupalith, and described retainer is provided with the straight pocket hole of rectangular.
Described a kind of ceramic bearing, is characterized in that, described roller is provided with restraining groove.
Compared with prior art, the beneficial effects of the utility model are: reasonable in design, by at the ceramic embedded raceway of bearing outer ring inwall, roller adopts the structure be made up of hollow cylinder roller and ceramic roller shell, retainer and bearing inner race adopt stupalith to make, can be implemented in the corrosion resistance of high corrosive environment lower bearing, improve the working life of bearing, increase and the skidding of the roller load caused because of centrifugal action can be suppressed in addition when High Rotation Speed, the mechanism that roller adopts hollow rollers and ceramic roll sleeve to combine, reduce the weight of roller, can reduce the centrifugal action of bearing outer ring when therefore rotating, and then working life extends greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-bearing outer ring, 2-bearing inner race, 3-retainer, 4-roller, 5-pottery raceway, 6-roller, 7-roller shell.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, and provides embodiment.
As shown in Figure 1, a kind of ceramic bearing of the utility model, comprises bearing outer ring 1, bearing inner race 2, retainer 3 and roller 4, in order to improve the corrosion resistance of bearing, is applicable to the use of high corrosion working environment,
At the ceramic embedded raceway 5 of bearing outer ring 1 inwall, bearing inner race 2 adopts stupalith to make, roller 4 adopts the structure be made up of hollow cylinder roller 6 and ceramic roller shell 7, retainer 3 is made up of stupalith, retainer 3 is established the straight pocket hole of rectangular, be arranged on position on roller 6 to limit roller shell 7, roller 6 arranges restraining groove.
By at the ceramic embedded raceway 5 of bearing outer ring 1 inwall, bearing inner race 2 and retainer 3 adopt stupalith to make, roller 4 adopts the structure be made up of hollow cylinder roller 6 and ceramic roller shell 7, can be implemented in the corrosion resistance of high corrosive environment lower bearing, improve the working life of bearing, increase and the skidding of roller 4 load caused because of centrifugal action can be suppressed in addition when High Rotation Speed, the mechanism that roller 4 adopts hollow rollers 6 and ceramic roll sleeve 7 to combine, reduce the weight of roller 4, can reduce the centrifugal action of bearing outer ring 1 when therefore rotating, and then working life extends greatly.
