Abstract
The utility model belongs to the technical field of machinery, and particularly relates to an improved shaft sleeve. The technical problems of unreasonable design and the like of the prior art are solved. The improved shaft sleeve comprises a cylindrical sleeve body, wherein the side part of the sleeve body is provided with a side hole, a positioning body is fixed in the side hole, the outer end of the positioning body extends out of the side hole, and the hardness of the positioning body is greater than the hardness of the sleeve body. Compared with the prior art, the improved shaft sleeve has the advantages of reasonable design, simple structure, low manufacturing cost, high precision, wear resistance, and long service life.
Description
Technical field
The utility model belongs to field of mechanical technique, especially relates to a kind of improved type axle sleeve.
Background technique
In moving element, cause the wearing and tearing of part because of long-term friction, must renewal part when the gap in axle and hole may wear to a certain degree; Therefore the artificer select in design that hardness is lower for use, wear resistance preferably material be axle sleeve or lining, can reduce the wearing and tearing of axle and seat like this, when axle sleeve or liner wear to a certain degree changing; Can practice thrift like this because of changing the cost of axle or seat, in general, lining adopts interference fit with seat; And adopt Spielpassung with axle, and because no matter how still can't avoid wearing and tearing, can only life-saving; And axial workpiece for the wall thickness of economical with materials according to the thrust load design axle sleeve of bearing needs, is generally selected cast copper and bearing metal material comparatively speaking than being easier to processing for use; Axle sleeve has the opening and the branch of opening not, and these will be according to the needs of structure.General axle sleeve can not bear thrust load, maybe can only bear less thrust load.
For example, the Chinese patent document discloses a kind of axle sleeve [application number: CN200720022010.0], comprises that the axle sleeve front end is fixedly connected with nut through packing ring, has 2 bar holes on the flange plate of its rear end.
Technical problems such as though such scheme has good transmission property, and it is not high still to exist precision, not wear-resistant.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, low cost of manufacture, and validity is high, the improved type axle sleeve of wear-resistant long service life.
For achieving the above object; The utility model has adopted following technical proposal: this improved type axle sleeve; Comprise being body cylindraceous, the sidepiece of described body has side opening, at the side opening internal fixation positioning body is arranged; The outer end of described positioning body extends to outside the side opening, and the hardness of described positioning body is greater than the hardness of body.
In above-mentioned improved type axle sleeve, the outside, the two ends of described body is respectively equipped with outer chamfer surface; The inboard, two ends of described body is respectively equipped with interior chamfer surface.
In above-mentioned improved type axle sleeve, described positioning body links to each other with side opening through worm structure.
In above-mentioned improved type axle sleeve, the outer end of described positioning body is taper type.
Compared with prior art, the advantage of this improved type axle sleeve is: reasonable in design, simple in structure, and low cost of manufacture, validity is high, wear-resistant long service life.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, body 1, side opening 2, positioning body 3, outer chamfer surface 4, interior chamfer surface 5.
Embodiment
As shown in Figure 1, this improved type axle sleeve comprises being body 1 cylindraceous, the sidepiece of body 1 have side opening 2, at side opening 2 internal fixation positioning body 3 is arranged, the outer end of described positioning body 3 extends to outside the side opening 2, the hardness of described positioning body 3 is greater than the hardness of body 1,
The outside, two ends of body 1 is respectively equipped with outer chamfer surface 4; The inboard, two ends of body 1 is respectively equipped with interior chamfer surface 5, and positioning body 3 links to each other with side opening 2 through worm structure, and the outer end of positioning body 3 is taper type.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as body 1, side opening 2, positioning body 3, outer chamfer surface 4, interior chamfer surface 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
