Abstract

The invention discloses an impeller shaft sleeve with protruding ridges. The impeller shaft sleeve comprises a hollow cylindrical shaft sleeve body. The protruding ridges are arranged on the shaft sleeve body. The two ends of each protruding ridge extend to the two end faces, in the axial direction, of the shaft sleeve body. A check ring is arranged on the end face of one end of the shaft sleeve body. The protruding ridges and the check ring are arranged on the outer wall of the shaft sleeve, precise matching between the shaft sleeve and connecting pieces is achieved, and vibration and noise are reduced. Meanwhile, the shaft sleeve can be conveniently detached without damaging other parts; and by means of other improvements, the abrasion resistance of the shaft sleeve is improved, detaching is avoided, cost is saved, and the effect is improved.

Description

A kind of impeller axle sleeve being provided with fin
Technical field
The present invention relates to a kind of impeller axle sleeve being provided with fin。
Background technology
Axle sleeve is a common part in Machine Design; especially, in clutch, in order to position and protect impeller, axle sleeve is set in outside rotating shaft; countershaft plays a protective role; the outer end of axle sleeve is generally fixed by tensioner interference fit with connector, or what spline was fixed, but after axle sleeve weares and teares; when replacing pulled down by needs; then inconvenient, and it is easy to scratch connector, shorten the service life of connector。Additionally, due to rotating shaft and the continuous pivoting friction of axle sleeve, need between rotating shaft and axle sleeve to be lubricated fully, otherwise the rate of wear is quickly, service life is comparatively short, but on the lubricating oil inside contact surface that needs to add between rotating shaft and axle sleeve, need to be added after rotating shaft being separated with axle sleeve again, making complicated operation, efficiency is low。
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that a kind of convenient dismounting, installation, noise is little, long service life, the convenient oiling impeller axle sleeve being provided with fin。
For achieving the above object, the technical scheme is that and provide a kind of impeller axle sleeve being provided with fin, including the circumference axis of a cylinder body of hollow, described sleeve body is provided with fin, described fin prolongs described sleeve body axial direction and arranges, and described sleeve body one end end face is provided with back-up ring。
In order to make, install and being easy to operate, it is preferred that technical scheme is, the outer surface of described fin is concordant with the outer circumference surface of described back-up ring。
In order to reduce pivoting friction, it is preferred that technical scheme is, the inwall of described sleeve body is provided with helical form oil groove。
For the ease of oil addition, it is preferred that technical scheme is, described helical form oil groove extends from sleeve body one end to the other end。
In order to prevent chute, it is preferred that technical scheme is, the cross section of described fin is rectangle。
Advantages of the present invention and having the beneficial effects that: the present invention, by the fin being provided with on axle sleeve outer wall and back-up ring, is axle sleeve and connector precise match, reduces vibration and noise, and make axle sleeve conveniently to dismantle, can't damage other parts;And oil addition according to the helical groove extending to sleeve body end face, can improve the wearability of axle sleeve, it is to avoid dismounting, save cost, improve effect。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention。
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described。Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this。
As it is shown in figure 1, a kind of impeller axle sleeve being provided with fin, including the cylinder axis body 1 of hollow, described sleeve body 1 being provided with fin 2, described fin 2 prolongs described sleeve body 1 axial direction and arranges, and described sleeve body 1 one end end face is provided with back-up ring 4。
The outer surface of described fin 2 is concordant with the outer circumference surface of described back-up ring 4。
The present invention preferably technical scheme also includes being provided with helical form oil groove on the inwall 3 of described sleeve body 1。
The present invention preferably technical scheme also includes, and described helical form oil groove extends from sleeve body 1 one end to the other end。
The present invention preferably technical scheme also includes, and the cross section of described fin 2 is rectangle。
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention。
