Abstract
The utility model discloses a shock-proof shaft sleeve. The shaft sleeve comprises a shaft sleeve body and a shaft hole, wherein the shaft hole is formed in the middle of the shaft sleeve body; the shaft sleeve body comprises a left half shaft sleeve body and a right half shaft sleeve body; the left half shaft sleeve body and the right half shaft sleeve body are butted through flanges, and respectively comprise an outer layer, a shock-proof layer and an inner layer; the shock-proof layer is positioned between the outer layer and the inner layer; the outer layer, the shock-proof layer and the inner layer are fixed through bolts; the abutting ends of the left half shaft sleeve body and the right half shaft sleeve body are provided with positioning sheaths and positioning grooves matched with the positioning sheaths respectively; lined rings are arranged on the outer layers at the open ends of the left half shaft sleeve body and the right half shaft sleeve body respectively; sealing grooves are formed in the inner layers of the open ends of the left half shaft sleeve body and the right half shaft sleeve body respectively. The shaft sleeve can prevent displacement caused by the reason that the shaft sleeve vibrates up and down together with a shaft, improves the integral stability, prolongs the service life, and is simple in structure, convenient to mount and replace and low in failure rate.
Description
Technical field
The utility model relates to mechanical accessory field, relates in particular to a kind of against shock axle sleeve.
Background technique
Axle sleeve refers to the sleeve on screw shaft or stern tube shaft; it is a vitals in mechanical field; conventionally be arranged in rotating shaft; countershaft shields; rotating shaft, in movement process, causes damage 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 simultaneously; and needn't change bearing, therefore use axle sleeve just can reduce the wearing and tearing of bearing.
But axle sleeve is in During Process of Long-term Operation, because axle sleeve and axle exist seismism in being used in conjunction with process, in rotation process, axle sleeve can be followed axle vertical tremor together, affect whole stability, more easily cause the wearing and tearing of axle sleeve, also can't be permanent working life.In addition, journal surface is subject to the effect of extruding force and the composite machine power of expansion set, will cause its permanent deformation, diameter reduction, and then cause mechanical expansion drive fit dynamics not reach the power that tightens of requirement, between axle sleeve and main shaft, there is matching gap, also easily cause the wearing and tearing of axle sleeve, reduction of service life.
Model utility content
The purpose of this utility model has been to provide a kind of against shock axle sleeve, in use, prevent axle sleeve follow axle together vertical tremor cause axle sleeve displacement, improve whole stability, extend the working life of axle sleeve, simple in structure, install and change conveniently, failure rate is low, axle sleeve hole is not yielding.
The technical solution adopted in the utility model is as follows:
A kind of against shock axle sleeve, comprise sleeve body and axis hole, axis hole is positioned at the middle part of sleeve body, described sleeve body comprises left demifacet sleeve body and right-half plane sleeve body, left demifacet sleeve body and right-half plane sleeve body dock by flange, described left demifacet sleeve body and right-half plane sleeve body all comprise skin, shakeproof layer and internal layer, shakeproof layer is positioned in the middle of outer and internal layer, described skin, shakeproof layer and internal layer are bolted, the locating slot that the butt end of described left demifacet sleeve body and right-half plane sleeve body is respectively equipped with location sheath and coordinates with location sheath, on the opening end skin of described left demifacet sleeve body and right-half plane sleeve body, be respectively equipped with grommet, on internal layer, be respectively equipped with sealed groove.
Described flange is provided with bolt mounting holes and positioning spline.
Described shakeproof layer is made by rubber material.
Described grommet and the skin of sleeve body are casting integrated moulding.
Described sealed groove is set to chamfering form.
Described chamfering is 45 degree chamferings.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is by arranging left and right two halves over glaze body, left and right two halves over glaze body connects by flange, two halves over glaze body butt end, left and right is provided with location sheath and locating slot, can effectively prevent axle sleeve displacement, reduce vibrations, simultaneously, in sleeve body, set up shakeproof layer, with bolt, be fixed, can obviously improve the shake-proof ability of axle sleeve, improve whole stability, skin at axle sleeve is provided with grommet, make to improve the intensity of axle sleeve, prevent that axle sleeve is out of shape in the process of using, extend the working life of axle sleeve, reduce costs, the sealed groove of chamfering form is set at the opening end of axle sleeve, make axle sleeve in work, guarantee sealing, control dust impurity etc. enters in bearing and goes, simple in structure, install and change conveniently, failure rate is low.
