Abstract
The invention provides a shaft sleeve, comprising a cylindrical main body, a spiral oil guiding groove recessed on the inner wall surface of the main body, and a first through hole and a second through hole provided on the outer wall surface of the main body. The first through hole and the second through hole penetrate the main body and communicate with the oil guiding groove. According to the invention, the two through holes are arranged on the shaft sleeve, such that lubricating oil can be conveniently added through the through holes, and thereby the convenience of lubricating oil addition is improved. Also, because the spiral oil guiding groove is recessed on the inner wall surface of the main body, the contact area of the shaft sleeve and the shaft can be effectively reduced, such that the friction force of the shaft sleeve is reduced, and the service life of the shaft sleeve is prolonged.
Description
Technical field
The present invention relates to a kind of axle sleeve, belong to mechanical design field.
Background technique
Axle sleeve is vitals in the mechanical design field, and axle sleeve is arranged on its protective action of countershaft in the rotating shaft usually.Because rotating shaft and axle sleeve are in continuous frictional rotation in supporting using process, all just need guarantee lubricated fully between axle sleeve and rotating shaft.
In the existing technology, be employed in usually between axle sleeve and the rotating shaft and add lubricant oil.Owing to need lubricant oil be added on the inside surface of contact between rotating shaft and the axle sleeve, thus after need rotating shaft and axle sleeve being split when adding again toward inner interpolation, whole process operation is loaded down with trivial details, brings great inconvenience to the user.
And the internal face of axle sleeve of the prior art is a continuous face normally, so the surface of contact between sleeve lining face and the rotating shaft is bigger, thereby causes rotating shaft in the process that self pivots, and the wearing and tearing of axle sleeve and rotating shaft are also bigger.
In view of this, be necessary axle sleeve of the prior art is improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of axle sleeve rational in infrastructure, in order to reduce the frictional force of axle sleeve, on the sidewall of axle sleeve, oilhole is set simultaneously the working life of improving axle sleeve, to realize the selflubricating of axle sleeve.
For realizing the foregoing invention purpose, the invention provides a kind of axle sleeve, comprise body cylindraceous,
Be arranged with a spiral oil guide slot on the internal face of said body, the outer wall of said body offers first through hole and second through hole, and said first through hole and second through hole run through said body and be connected with said oil guide slot.
As further improvement of the present invention, the end, two ends of said oil guide slot is communicated with said first through hole and second through hole respectively.
As further improvement of the present invention, said oil guide slot edge is semicircle perpendicular to the sectional shape on the helical trajectory direction of said oil guide slot.
As further improvement of the present invention, the degree of depth that said oil guide slot is arranged with into the internal face of said body is 1/5 of a said base side wall thickness.
Compared with prior art, the invention has the beneficial effects as follows: through two penetration holes are set on the axle sleeve, can in penetration hole, add lubricant oil easily, improve the convenience of adding lubricant oil; Owing on the internal face of axle sleeve, be arranged with a spiral oil guide slot, can reduce the area of contact of axle sleeve and rotating shaft effectively, thereby reduce the frictional force of axle sleeve simultaneously, and the working life of having improved axle sleeve.

Embodiment
Below in conjunction with each mode of execution shown in the drawings the present invention is elaborated; But should be noted that; These mode of executions are not limitation of the present invention; The function that those of ordinary skills do according to these mode of executions, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Please join Fig. 1 to a kind of embodiment of a kind of axle sleeve of the present invention shown in Figure 3.In this mode of execution, a kind of axle sleeve 10 comprises body 1 cylindraceous, is arranged with a spiral oil guide slot 110 on the internal face 11 of said body 1.The outer wall 12 of this body 1 offers first through hole 111 and second through hole 121, and this first through hole 111 and second through hole 121 run through said body 1 and be connected with said oil guide slot 110.
In this mode of execution, the end, two ends of this oil guide slot 110 is communicated with said first through hole 111 and second through hole 121 respectively.Through such setting, can in first through hole 111 or second through hole 121, add lubricant oil, improved the convenience of adding lubricant oil, so just need axle sleeve 10 and rotating shaft not disassembled to add lubricant oil.Simultaneously, lubricant oil can be transported to lubricant oil on the internal face 11 of this axle sleeve 10 along spiral oil guide slot 110 equably, to realize the good lubrication to this axle sleeve 10.
To shown in Figure 5, in this mode of execution, these oil guide slot 110 edges are semicircle perpendicular to the sectional shape on the helical trajectory direction of said oil guide slot 110 in conjunction with Fig. 4.To be arranged with the degree of depth into the internal face 11 of said body 1 be 1/5 of said body 1 sidewall thickness to this oil guide slot 110 simultaneously.
Through this structure, can reduce the area of contact between rotating shaft (not shown) and this axle sleeve 10 effectively, thereby reduce the frictional force of this axle sleeve 10, and improve the working life of this axle sleeve 10.
The listed a series of detailed description of preceding text only is specifying to feasibility mode of execution of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any reference character in the claim be regarded as limit related claim.
In addition; Describing according to mode of execution though should be appreciated that this specification, is not that each mode of execution only comprises an independently technological scheme; This narrating mode of specification only is for clarity sake; Those skilled in the art should make specification as a whole, and the technological scheme among each embodiment also can form other mode of executions that it will be appreciated by those skilled in the art that through appropriate combination.
