Description
Technical field
The utility model relates to a kind of mechanical fitting, and being specifically related to can axial displacement ceramic ball bearing.
Background technique
Bearing is a kind of important spare part in contemporary machinery, and its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.
The thermal expansion coefficient of ceramic ball is little, bearing ball will be caused to expand because of the reason of temperature in high temperature environments, substantially increase the serviceability temperature of whole bearing like this, the temperature of plain bearing at about 160 degree, ceramic ball can reach more than 220 degree.Ceramic ball has oil-free self lubrication attribute, and ceramic ball friction factor is little, so ceramic ball bearing has very high rotating speed.Ceramic ball can not add any grease, even if that is grease is killed, bearing still can operate, and doing so avoids in plain bearing because the generation of the bearing premature failure phenomenon caused killed by grease.Adopt the bearing of ceramic ball, can make to insulate between the Internal and external cycle of bearing, because ceramic ball is insulator, by ceramic ball between the Internal and external cycle of bearing, just can reach the effect of insulation, so just enable bearing use under the environment of conduction.
Also must have dimensional stability at different temperatures as bearing material, to ensure that bearing is under the working environment of temperature variation, keep accurate size and to coordinate accurately, also must possess anticorrosive, anti-resolving power in particular circumstances.Lasso and rolling element point of contact are subject to the effect of applied load and rotation, repeatedly produce contact and distortion, due to steel bearings own material performance characteristics, the principal mode of bearing failure is fatigue flake, fatigue life is short, application area is very limited, and stupalith has low density, moderate elasticity modulus, thermal expansion coefficient is little, hardness is high, high temperature resistant, corrosion-resistant, without advantages such as magnetic, ceramic ball bearing can significantly improve bearing touch fatigue life, the very big application expanding rolling bearing, various highi degree of accuracy can be widely used in, high rotating speed lathe, automobile, racing car, subway, motor, aeroengine, Petro-Chemical Machinery, the fields such as metallurgical machinery.
Bearing needs to adapt to high rotating speed, has and bears high load capacity, and the temperature that common bearing pivoting friction produces is high, and product consistency is low, and insufficient strength is high, and overall mechanical property is general, and it is not firm that retainer is connected with inner ring and outer ring, and ceramic ball can be caused cracked.
Model utility content
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, reasonable in design, easy to use can axial displacement ceramic ball bearing, it can adapt to higher rotation speed, have and bear high load capacity, be applicable to the environment of higher temperature, intensity is high, overall mechanical property is good, it is firm that retainer is connected with inner ring and outer ring, ceramic ball can be prevented cracked, long service life.
In order to solve the problem existing for background technique, the technical solution adopted in the utility model is: it comprises outer ring, inner ring, ball ball, retainer, skeleton, described ball ball is arranged between outer ring and inner ring, ball ball is full ceramic ball, retainer is provided with between outer ring and inner ring, ball ball is located in retainer, retainer partly wraps up ball ball, guidance spheres ball also holds it in bearing, the skeleton being convenient to load and unload is provided with between retainer and outer ring, a part for skeleton is between outer ring and inner ring, another part is located at the two ends up and down of retainer, outer ring is fixed in bearing support, outer ring and inner ring have a respective outer raceway and interior raceway respectively, face each other, respective concave surface is towards the other side, ball ball is arranged between raceway.
After adopting said structure, the utility model beneficial effect is: its structure is simple, higher rotation speed can be adapted to, have and bear high load capacity, be applicable to the environment of higher temperature, intensity is high, overall mechanical property is good, it is firm that retainer is connected with inner ring and outer ring, ceramic ball can be prevented cracked, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.

Description of reference numerals: outer ring 1, inner ring 2, ball ball 3, retainer 4, skeleton 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, this embodiment adopts following technological scheme: it comprises outer ring 1, inner ring 2, ball ball 3, retainer 4, skeleton 5, described ball ball 3 is arranged between outer ring 1 and inner ring 2, ball ball 3 is full ceramic ball, retainer 4 is provided with between outer ring 1 and inner ring 2, ball ball 3 is located in retainer 4, retainer 4 partly wraps up ball ball 3, guidance spheres ball 3 also holds it in bearing, the skeleton 5 being convenient to load and unload is provided with between retainer 4 and outer ring 1, a part for skeleton 5 is between outer ring 1 and inner ring 2, another part is located at the two ends up and down of retainer 4, outer ring 1 is fixed in bearing support, outer ring 1 and inner ring 2 have a respective outer raceway and interior raceway respectively, face each other, respective concave surface is towards the other side, ball ball 3 is arranged between raceway, such design can prevent the ball ball 3 of full ceramic material cracked, simultaneously that retainer 4 can be made to be connected with inner ring 2 and outer ring 1 is firm for skeleton 5.
Ball ball 3 is spheroids that stupalith is made, spheroid itself can bear the larger radial direction based on radial compound, axially two-way joint load and torque load, the further attribute of, oil-free self lubrication high temperature resistant in conjunction with stupalith, makes a kind of high-precision ceramic ball bearing capable of axial displacement have very high rotating speed and bears the feature of axial displacement.
This embodiment structure is simple, and can adapt to higher rotation speed, have and bear high load capacity, be applicable to the environment of higher temperature, intensity is high, and overall mechanical property is good, and it is firm that retainer is connected with inner ring and outer ring, ceramic ball can be prevented cracked, long service life.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
