Abstract
The invention discloses a shaft sleeve which comprises a shaft sleeve body, wherein a through hole is formed in the middle of the shaft sleeve body; a crack is arranged in the shaft sleeve body; the crack is not parallel to the rotation center of the shaft sleeve body. According to the shaft sleeve, as the crack is not parallel to the rotation center of the shaft sleeve body, friction, consistent with the rotating direction of a spindle, is applied to the shaft sleeve body due to the rotation of the spindle when the shaft sleeve body is used, and the friction tends to enlarge the crack; as the contact surface of the spindle and the shaft sleeve body is a straight line parallel to the rotation center of the shaft sleeve body, the distances between the force bearing points on the straight line and the corresponding crack are not consistent, and the force moments are not consistent. Therefore, the trend of enlarging the crack in the shaft sleeve body slows down. The shaft sleeve is excellent in heat dissipation performance and has low possibility of deformation.
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 on-deformable axle sleeve.
Background technique
In prior art, rotating shaft generally all is arranged in bearing by axle sleeve, generally, rotating shaft is in movement process, cause wearing and tearing because of long-term wearing and tearing, just must change axle and axle sleeve when the gap of axle and axle sleeve hole may wear to a certain degree, and therefore better bearing uses axle sleeve just can reduce the wearing and tearing of bearing simultaneously.But the heat dispersion at this axle sleeve is poor, in recent years, had a kind of axle sleeve that is provided with opening on the axle sleeve body on market, the rotating center of described opening and axle sleeve be arranged in parallel; This axle sleeve with opening can effectively discharge the heat produced 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 the use, opening can be increasing, make the rotation of axle or bearing produce deviation, affect machining accuracy.
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 on-deformable axle sleeve.
For achieving the above object, the technical solution used in the present invention is: a kind of axle sleeve comprises the axle sleeve body; The middle part of described axle sleeve body is provided with through hole; Be provided with crack on described axle sleeve body; The rotating center of described crack and axle sleeve body is not parallel.
Preferably, described crack is to be formed by cuboid and the cutting of axle sleeve body.
Preferably, described crack is comprised of the opening of multistage bending.
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 the axle sleeve body is in use because of the rotation of rotating shaft, make the axle sleeve body be subject to the frictional force consistent with the 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 the axle sleeve body can be slack-off; Perfect heat-dissipating of the present invention, and not yielding.
The 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;
The second embodiment's that accompanying drawing 2 is axle sleeve of the present invention stereogram;
Wherein: 1, axle sleeve body; 2, through hole; 3, crack.
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, comprise axle sleeve body 1; The middle part of described axle sleeve body 1 is provided with through hole 2; Be provided with crack 3 on described axle sleeve body 1; Described crack 3 is not parallel with the rotating center of axle sleeve body 1.
As shown in Figure 1, described crack 3 is to be formed by cuboid and 1 cutting of axle sleeve body.
As shown in Figure 2, described crack 3 is comprised of the opening of multistage bending.
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 the axle sleeve body is in use because of the rotation of rotating shaft, make the axle sleeve body be subject to the frictional force consistent with the 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 the axle sleeve body can be slack-off; Perfect heat-dissipating of the present invention, and not yielding.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the 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)
