Abstract

The utility model provides a shaft sleeve which comprises a cylindraceous body. The inner wall surface of the body is provided with a first groove, a second groove and a third groove which connects the first groove and the second groove concavely, the body is also provided with a first through hole and a second through hole, the first through hole penetrates through the body and is communicated with the first groove, and the second through hole penetrates through the body and is communicated with the second groove. Due to the fact that the two through holes are arranged in the shaft sleeve, lubricating oil can be easily added into the through holes, self-lubricating of the shaft sleeve is achieved, convenience of adding the lubricating oil is improved, and meanwhile a plurality of grooves are arranged on the inner wall surface of the shaft sleeve so that contacting area of the shaft sleeve and a rotating shaft is effectively reduced, and accordingly friction of the shaft sleeve is reduced, and service life of the shaft sleeve is prolonged.

Description

Axle sleeve

Technical field

The utility model relates to axle sleeve, belongs 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.

The model utility content

The purpose of the utility model 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 above-mentioned model utility purpose; The utility model provides a kind of axle sleeve; Comprise body cylindraceous, be concaved with first groove, second groove on the internal face of said body and connect the 3rd groove of said first groove and second groove that said body also offers first through hole and second through hole; Said first through hole runs through body and is connected with first groove, and said second through hole runs through body and is connected with second groove.

As the further improvement of the utility model, said first groove and second groove are arranged in parallel, and are periphery on the internal face of said body.

As the further improvement of the utility model, the bearing of trend of said the 3rd groove is identical with the lengthwise bearing of trend of said body.

As the further improvement of the utility model, the cross section of said the 3rd groove is semicircle.

As the further improvement of the utility model, said the 3rd groove and said first groove and the vertical setting each other of second groove.

As the further improvement of the utility model, said first groove, second groove and the 3rd groove are arranged with into the degree of depth of the internal face of said body consistent.

As the further improvement of the utility model, the width of said first groove and second groove is identical.

Compared with prior art, the beneficial effect of the utility model is: through two through holes are set, can in through hole, add lubricant oil easily on axle sleeve, realize the selflubricating of this axle sleeve, improve the convenience of adding lubricant oil; Because some grooves are set on the internal face of axle sleeve, can reduce the area of contact of axle sleeve and rotating shaft effectively, thereby reduce the frictional force of axle sleeve, the working life of having improved axle sleeve simultaneously.

Embodiment

Below in conjunction with each mode of execution shown in the drawings the utility model is elaborated; But should be noted that; These mode of executions are not the restriction to the utility model; The function that those of ordinary skills do according to these mode of executions, method, or structural equivalent transformation or substitute all belong within the protection domain of the utility model.

Please join a kind of embodiment of Fig. 1 to the utility model axle sleeve shown in Figure 3.Wherein Fig. 1 is the stereogram in a kind of embodiment of the utility model axle sleeve.In this mode of execution, axle sleeve 10, it comprises body 1 cylindraceous, the inside of this body 1 is hollow structure, in order to accommodate rotating shaft (not shown).

In this mode of execution, be concaved with first groove 111, second groove 121 on the internal face 11 of this body 1 and connect the 3rd groove 151 of said first groove 111 and second groove 121.This body 1 also offers first through hole 131 and second through hole 141, and this first through hole 131 runs through body 1 and is connected with first groove 111, and this second through hole 141 runs through body 1 and is connected with this second groove 121.

Through such setting, can in first through hole 131 or second through hole 141, add lubricant oil easily, improved the convenience of adding lubricant oil, so just need axle sleeve and rotating shaft not disassembled to add lubricant oil.

In conjunction with shown in Figure 4, in this mode of execution, this first groove 111 and second groove 121 are arranged in parallel, and are periphery on the internal face 11 of this body 1.The bearing of trend of the 3rd groove 151 is identical with the lengthwise bearing of trend of this body 1.The cross section of the 3rd groove 151 is semicircle.The 3rd groove 151 and first groove 111 and the 121 mutual vertical settings of second groove.Said first groove 111, second groove 121 and the 3rd groove 151 are arranged with into the degree of depth of the internal face 11 of said body 1 consistent.The width of this first groove 111 and second groove 121 is identical.

Owing on the internal face 11 of body 1, be concaved with first groove 111, second groove 121 and connect the 3rd groove 151 of said first groove 111 and second groove 121.Therefore reduced the area of contact of axle sleeve 10 effectively, thereby reduced the frictional force of this axle sleeve 10, realized the selflubricating of this axle sleeve 10, reduced the wearing and tearing of this axle sleeve 10, and improved the working life of this axle sleeve 10 with rotating shaft.
