Abstract
The invention discloses a shaft sleeve. The shaft sleeve comprises a shaft sleeve body and a long-strip hole, wherein a shaft sleeve hole is formed in the middle part of the shaft sleeve body; a crack is formed in the shaft sleeve body; the crack is formed in a manner that the crack and the rotating center of the shaft sleeve body form an angle; the long-strip hole is formed in a manner that the long-strip hole and the crack form an angle, and the long-strip hole penetrates through the crack. The shaft sleeve has the advantages that the heat dissipating performance is good and the shaft sleeve hole is difficultly deformed.
Description
Technical field
The present invention relates to a kind of improvement of axle sleeve, refer in particular to a kind of perfect heat-dissipating, and the on-deformable axle sleeve of axle sleeve hole.
Background technique
In prior art, rotating shaft is generally all arranged in bearing by axle sleeve, generally, rotating shaft is in movement process, because of long-term wearing and tearing, cause wearing and tearing, when the gap of axle and axle sleeve hole may wear to a certain degree, just must change axle and axle sleeve simultaneously, and needn't change bearing, therefore use axle sleeve just can reduce the wearing and tearing of bearing.But the heat dispersion at this axle sleeve is poor, in recent years, on market, had a kind of axle sleeve that is provided with opening on axle sleeve body, the rotating center of described opening and axle sleeve be arranged in parallel; This axle sleeve with opening can effectively discharge the heat producing in friction process, makes split bush because of temperature overheating, not make axle or bearing infringement, has also facilitated interpolation lubricant oil simultaneously.But in long-term use, opening can be increasing, make the rotation of axle or bearing produce deviation, affect machining accuracy.For this reason, we have researched and developed a kind of perfect heat-dissipating, and the on-deformable axle sleeve of axle sleeve hole.
Summary of the invention
The present invention seeks to provides a kind of perfect heat-dissipating in order to overcome the deficiencies in the prior art, and the on-deformable axle sleeve of axle sleeve hole.
For achieving the above object, the technical solution used in the present invention is: a kind of axle sleeve, comprises axle sleeve body, strip hole; The middle part of described axle sleeve body is provided with axle sleeve hole; On described axle sleeve body, be provided with crack; The angled setting of rotating center of described crack and axle sleeve body; Described strip hole and crack are angle setting, and through crack.
Preferably, described crack is comprised of the opening of multistage bending.
Preferably, the end parts parallel of described strip hole and axle sleeve body, and be positioned at the middle part of axle sleeve body.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Axle sleeve of the present invention, because the rotating center of crack and axle sleeve body is not parallel, and axle sleeve body is in use because of the rotation of rotating shaft, make axle sleeve body be subject to the frictional force consistent with rotating shaft sense of rotation, these frictional force have the trend that crack is increased, because rotating shaft and the surface of contact of axle sleeve body are parallel and a straight line of the rotating center of axle sleeve body, like this, the stressed distance to reflection crack of each point on described straight line is inconsistent, and moment is also inconsistent, thereby the crack increase tendency on axle sleeve body can be slack-off; Meanwhile, arranging of described strip hole can increase the deformability of axle sleeve body and recovery capability, after axle sleeve body distortion, can automatically recover in time; Perfect heat-dissipating of the present invention, and axle sleeve hole is not yielding.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The first embodiment's that accompanying drawing 1 is axle sleeve of the present invention stereogram;
Wherein: 1, axle sleeve body; 2, axle sleeve hole; 3, crack; 4, strip hole.
embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
A kind of axle sleeve of the present invention, comprises axle sleeve body 1, strip hole 4; The middle part of described axle sleeve body 1 is provided with axle sleeve hole 2; On described axle sleeve body 1, be provided with crack 3; Described crack 3 becomes 45 degree settings with the rotating center of axle sleeve body 1; Described strip hole 4 is 90 degree settings with crack 3, and through crack 3; In the present embodiment, described crack 3 is formed by a plane and the cutting of axle sleeve body; The opening that certain described crack 3 also can be provided with multistage bending forms; The end parts parallel of described strip hole 4 and axle sleeve body 1, and be positioned at the middle part of axle sleeve body 1.
Axle sleeve of the present invention, because the rotating center of crack and axle sleeve body is not parallel, and axle sleeve body is in use because of the rotation of rotating shaft, make axle sleeve body be subject to the frictional force consistent with rotating shaft sense of rotation, these frictional force have the trend that crack is increased, because rotating shaft and the surface of contact of axle sleeve body are parallel and a straight line of the rotating center of axle sleeve body, like this, the stressed distance to reflection crack of each point on described straight line is inconsistent, and moment is also inconsistent, thereby the crack increase tendency on axle sleeve body can be slack-off; Meanwhile, arranging of described strip hole can increase the deformability of axle sleeve body and recovery capability, after axle sleeve body distortion, can automatically recover in time; Perfect heat-dissipating of the present invention, and axle sleeve hole is not yielding.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
