Description
Technical field
This utility model relates to a kind of machine components, specifically a kind of axle sleeve, belongs to machinery field.
Background technology
Axle sleeve is a vitals in mechanical design field, and axle sleeve is generally arranged at its protection of countershaft in rotating shaft and makees
With.Owing to rotating shaft and axle sleeve are in continuous frictional rotation during supporting the use, thus high temperature can be produced when rotated so that
Lubricating oil deterioration between rotating shaft and axle sleeve, lubricant effect is greatly reduced, and dust and the produced miscellaneous bits of friction also can gradually amass
Tire out and, during life-time service, axle sleeve its be easily worn, abnormal sound can be produced, service life is shorter.
Utility model content
The purpose of this utility model is to overcome defect present in prior art, it is provided that a kind of axle sleeve, wear-resisting, is difficult to mill
Damage.Technical solutions of the utility model are 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 by axle sleeve
One end of main body extends inwardly to the other end position near axle sleeve main body, and described oil filler point is positioned at the lengthwise of axle sleeve main body and prolongs
Stretch and on the outer surface that direction is identical, be uniformly distributed and run through axle sleeve body side, in described oil filler point, be provided with pad and screw, institute
Stating the screw length thickness less than axle sleeve main body, the 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%, and fine and close WC is brilliant
Intergranular is organized as pearlite, and structure distribution in pelletized form.
Described oil groove is rectangular.
Described oil groove is helically arranged on axle sleeve body inner surface, and described gasket material is rubber.
The beneficial effects of the utility model are: arrange wear-resistant coating by the inner surface at sleeve body, improve it wear-resisting
Property, the most easy to wear, abnormal sound will not be produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is oil filler hole structure figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described, it is clear that described is only this reality
By novel a part of embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creation
Property work premise under the every other embodiment that obtained, broadly fall into the scope of this utility model protection.
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 sets
Inner surface at axle sleeve is extended inwardly to the other end position near axle sleeve main body 1, described oil groove by one end of axle sleeve main body 1
2 is rectangular, and described oil groove 2 is helically arranged on axle sleeve main body 1 inner surface, and described oil filler point 3 is positioned at the lengthwise of axle sleeve main body 1
It is uniformly distributed and runs through axle sleeve main body 1 side on the outer surface that bearing of trend is identical, in described oil filler point 3, be provided with pad 4 and spiral shell
Nail 5, described pad 4 material is rubber, and described screw 5 length is less than the thickness of axle sleeve main body, and the inner surface in axle sleeve main body 1 sets
Being equipped with wear-resistant coating, described wear-resistant coating is WC height dense ceramic layers, and the WC gauge of described WC height dense ceramic layers is 20-
40 μm, volume fraction reaches more than 90%, is organized as pearlite, and structure distribution in pelletized form between fine and close WC grain.
WC good toughness, resistance to shock loads and abrasion resistance are good, are combined with matrix and have preferable resistance to corrosion, and it
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, is entered the purpose of this utility model, technical scheme and beneficial effect
One step describes in detail, be it should be understood that and the foregoing is only detailed description of the invention of the present utility model, is not used to limit
Fixed protection domain of the present utility model, all within spirit of the present utility model and principle, any amendment, the equivalent made are replaced
Change, improvement etc., within should be included in protection domain of the present utility model.
