Abstract
The invention discloses a shaft sleeve. The shaft sleeve is composed of a shaft sleeve body, an oil groove and oil injection holes. The oil groove is formed in the inner surface of the shaft sleeve, and extends inwards to the position close to the other end of the shaft sleeve body from one end of the shaft sleeve body, the oil injection holes are evenly distributed in the same outer surface of the longitudinal extension direction of the shaft sleeve body and penetrate one side of the shaft sleeve body, gaskets and screws are arranged in the oil injection holes, the length of the screws is smaller than the thickness of the shaft sleeve body, and a wear-resisting coating is arranged on the inner surface of the shaft sleeve body.
Description
Technical field
The present invention relates to a kind of machine components, specifically a kind of axle sleeve, belong to machinery field.
Background technology
Axle sleeve is a vitals in mechanical design field, and axle sleeve is generally arranged at its protective effect of countershaft in rotating shaft.Owing to rotating shaft and axle sleeve are in continuous frictional rotation during supporting the use, thus high temperature can be produced when rotated, lubricating oil between rotating shaft and axle sleeve is deteriorated, lubricant effect is greatly reduced, dust and the produced miscellaneous bits of friction also can gradually accumulate, during life-time service, axle sleeve its be easily worn, can produce abnormal sound, service life is shorter.
Summary of the invention
It is an object of the invention to overcome defect present in prior art, it is provided that a kind of axle sleeve, wear-resisting, the most easy to wear.Technical solution of the present invention is as follows:
A kind of axle sleeve, forms including axle sleeve main body, oil groove and oil filler point；Described oil groove is located at the inner surface of axle sleeve and is extended inwardly to the other end position near axle sleeve main body by one end of axle sleeve main body, described oil filler point is positioned on the outer surface that the lengthwise bearing of trend of axle sleeve main body is identical and is uniformly distributed and runs through axle sleeve body side, pad and screw it is provided with in described oil filler point, described screw length is less than the thickness of axle sleeve main body, inner surface in axle sleeve main body is provided with wear-resistant coating, and described wear-resistant coating is WC height dense ceramic layers.
The WC gauge of described WC height dense ceramic layers is 20-40 μm, and volume fraction reaches more than 90%, is organized as pearlite, and structure distribution in pelletized form between fine and close WC grain.
Described oil groove is rectangular.
Described oil groove is helically arranged on axle sleeve body inner surface, and described gasket material is rubber.
The invention have the benefit that and wear-resistant coating is set by the inner surface at sleeve body, improve its wearability, the most easy to wear, abnormal sound will not be produced.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is oil filler hole structure figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described, it is clear that described is only a part of embodiment of the present invention.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
As depicted in figs. 1 and 2: a kind of axle sleeve, form including axle sleeve main body 1, oil groove 2 and oil filler point 3；Described oil groove 2 is located at the inner surface of axle sleeve and is extended inwardly to the other end position near axle sleeve main body 1 by one end of axle sleeve main body 1, described oil groove 2 is rectangular, described oil groove 2 is helically arranged on axle sleeve main body 1 inner surface, described oil filler point 3 is positioned on the outer surface that the lengthwise bearing of trend of axle sleeve main body 1 is identical and is uniformly distributed and runs through axle sleeve main body 1 side, pad 4 and screw 5 it is provided with in described oil filler point 3, described pad 4 material is rubber, described screw 5 length is less than the thickness of axle sleeve main body, inner surface in axle sleeve main body 1 is provided with wear-resistant coating, described wear-resistant coating is WC height dense ceramic layers, the WC gauge of described WC height dense ceramic layers is 20-40 μm, volume fraction reaches more than 90%, it is organized as pearlite between fine and close WC grain, and structure distribution in pelletized form.
WC good toughness, resistance to shock loads and abrasion resistance are good, be combined with matrix and there is preferable resistance to corrosion, and it is good with iron and steel wettability, chemical stability and the wearability of WC height dense ceramic layers are good, have low-friction coefficient, high rigidity, low-surface-energy and low thermal conductiv-ity.
Above-described detailed description of the invention; the purpose of the present invention, technical scheme and beneficial effect are further described; it is it should be understood that; the foregoing is only the detailed description of the invention of the present invention; the protection domain being not intended to limit the present invention; all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, should be included within the scope of the present invention.
