Abstract
The utility model discloses a shaft liner. The shaft liner comprises a cylindrical sleeve, wherein a shaft hole is formed in the middle of the sleeve; the shaft hole comprises small holes and a big hole; the small holes are formed in the two ends of the sleeve and the big hole is formed in the middle; annular positioning grooves are formed in the outer walls of the two ends of the sleeve; sealing steps are arranged on the inner walls; sealing rings are arranged inside the sealing steps. According to the utility model, the shaft hole with different diameters is arranged in the middle of the cylindrical sleeve, the small holes are formed in the two ends of the sleeve, and the big hole is formed in the middle, so that when the shaft liner is used, the contacting area between a shaft and the shaft liner can be reduced, the friction can be effectively reduced, the problem of serious abrasion can be avoided, the service life can be prolonged, and the production cost can be lowered; in addition, the annular positioning grooves are formed in the outer walls of the two ends of the sleeve, which is beneficial to the mounting and fixing of the shaft liner; the sealing rings are arranged on the inner walls of the two ends of the shaft liner, so that the liner can be guaranteed to be sealed in the working process, and dust, impurities and the like can be prevented from entering a bearing.
Description
Technical field
The utility model relates to mechanical Component field, relates in particular to a kind of muff.
Background technique
In the time that machinery is moved, axle High Rotation Speed, in order to improve the stability of axle, avoids axle because frictional heat causes wearing and tearing, improves the working life of axle, all can fix a lining at the skin of axle, and axle is protected.But be arranged at present the lining outside axle, in the time of axle High Rotation Speed, and serious wear between axle, working life is short, in use for some time, liner wear is serious for machinery equipment, just needs to change, and user cost is high, and the installation and removal of lining all very bother, and waste a large amount of manpowers.
Model utility content
The purpose of this utility model has been to provide a kind of muff that can reduce wearing and tearing, long service life, and easy for installation, cost of production is low, has saved user cost.
The technical solution adopted in the utility model is as follows:
A kind of muff, comprises cylindrical sleeve, and described sleeve center is provided with axis hole, described axis hole is made up of aperture and macropore, and sleeve two ends are aperture, and centre is macropore, described sleeve two ends outer wall is provided with annular positioning groove, and inwall is provided with sealed step, is provided with seal ring in sealed step.
The twice that described large bore dia is hole diameter.
Described large hole depth is 3/5 of cylindrical sleeve height.
The degree of depth of described sleeve two ends aperture is the same.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is by arranging the different axis hole of diameter at cylindrical sleeve center, sleeve two ends are aperture, centre is macropore, in use, can reduce the area of contact between axle and muff, effectively reduce friction, avoid the problem of serious wear, increase the service life, reduced cost of production; Meanwhile, on the outer wall of sleeve two ends, be provided with annular positioning groove, be conducive to the installation of muff with fixing, easy to use; At the inwall at muff two ends, seal ring is set again, makes lining in work, ensure sealing, prevent that dust impurity etc. from entering into bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model will be further described.
Referring to accompanying drawing, a kind of muff, comprises cylindrical sleeve 1, described sleeve center is provided with axis hole 2, and described axis hole 2 is made up of aperture 3 and macropore 4, and sleeve 1 two ends are aperture 3, centre is macropore 4, and macropore 4 diameters are the twice of aperture 3 diameters, and described is large, 4 degree of depth are cylindrical shroud, 3/5 of 1 height, the degree of depth of sleeve two ends aperture is the same, and described sleeve 1 two ends outer wall is provided with annular positioning groove 5, inwall is provided with sealed step 6, is provided with seal ring 7 in sealed step.In use, axle only contacts with aperture 3 inwalls at sleeve 1 two ends muff of the present utility model, can reduce the area of contact between axle and muff, effectively reduces friction, avoids the problem of serious wear, increases the service life, and reduces production costs; Meanwhile, on sleeve 1 two ends outer wall, be provided with annular positioning groove 5, be conducive to the installation of muff with fixing; At the inwall at muff two ends, seal ring 7 is set again, makes lining ensure sealing in when work, prevent that dust impurity etc. from entering into bearing.
