Abstract
The invention relates to a shaft sleeve which comprises a shaft sleeve body and is characterized in that the cross section of the shaft sleeve body is L-shaped; an oil groove is formed in the inner wall of the shaft sleeve body in the length direction of the shaft sleeve body; the two ends of the oil groove are limited in the shaft sleeve body; the two end faces of the shaft sleeve body are parallel; a groove is formed in the side wall of the end face with a smaller external diameter. When the rotary shaft of the shaft sleeve rotates at a high speed, lubricating oil in a spiral groove on the inner wall of the copper shaft sleeve plays a good self-lubricating cooling function.
Description
Technical field
The present invention relates to a kind of improvement of axle sleeve, particularly a kind of axle sleeve getting final product selflubricating and can lower the temperature again.
Background technique
At present, conventional axle sleeve, have plenty of the sidewall punching lubrication at axle sleeve, some sidewalls open groove, and these all need people's constantly lubricating oil filling, moreover sidewall opens the intensity that groove can reduce parts.For this reason we have developed a kind of can the axle sleeve that can lower the temperature again of selflubricating.
Summary of the invention
The present invention seeks to provide a kind of axle sleeve getting final product selflubricating and can lower the temperature to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of axle sleeve, comprises sleeve body, and the cross section of described sleeve body is L-shaped, and the inwall of described sleeve body is provided with oil groove along the length direction of sleeve body; The two ends of described oil groove all end at the inside of sleeve body; Two end faces of described sleeve body are parallel, and the sidewall of the end face that external diameter is little is provided with groove.
Preferably, described oil groove is arranged in the shape of a spiral.
Preferably, the cross section of described oil groove is circular arc, and the radius of described circular arc is less than the half of the wall thickness of sleeve body.
Preferably, the end of described oil groove is equal with the distance of the end face of corresponding sleeve body, and is greater than zero.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Axle sleeve of the present invention is when rotating shaft high speed rotating, and the lubricant oil in copper bush spiral inner wall groove plays good selflubricating cooling effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the plan view of axle sleeve of the present invention;
Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1;
Wherein: 1, sleeve body; 2, oil groove; 3, groove.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1,2 is a kind of axle sleeve of the present invention, comprises sleeve body 1, and the cross section of described sleeve body 1 is L-shaped, and the inwall of described sleeve body 1 is provided with oil groove 2 along the length direction of sleeve body 1; The two ends of described oil groove 2 all end at the inside of sleeve body 1; Two end faces of described sleeve body 1 are parallel, and the sidewall of the end face that external diameter is little is provided with groove 3; Described oil groove 2 is arranged in the shape of a spiral; The cross section of described oil groove 2 is circular arc, and the radius of described circular arc is less than the half of the wall thickness of sleeve body 1; The end of described oil groove 2 is equal with the distance of the end face of corresponding sleeve body 1, and is greater than zero.
In the present embodiment, as accompanying drawing 1, shown in Fig. 2, the distance of the end face of the sleeve body 1 that the end distance of described oil groove 2 is corresponding is equal and be greater than zero, and the radius of arc of described oil groove 2 is less than the half of the wall thickness of sleeve body 1, does not affect the intensity of axle sleeve, when rotating shaft high speed rotating in axle sleeve, lubricant oil in oil groove 2 can play good self-lubricating function, and resistance is little, and rotating shaft temperature also can reduce.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
