Abstract
The utility model discloses a sleeve, which comprises a cylindrical sleeve body, wherein a circular groove in the radial direction and an axial groove of the vertically radial circular groove; an oil hole is formed in the side wall of the sleeve body; the oil hole is communicated with the circular groove; seal grooves are formed in two ends of the sleeve body. According to the utility model, a radially circular groove and an axial groove of the vertically axial circular groove are formed in the inner wall of the sleeve, so that the contact area of the sleeve inner wall and a shaft is effectively reduced, the friction between the sleeve and the shaft is reduced; wear of the sleeve in the use process is reduced to some extent, and the service life of the sleeve is prolonged; the oil hole is formed in the side wall of the sleeve to facilitate the filling of lubricant; the lubrication effect is good; the seal grooves are formed in the two ends of the sleeve body, so that the air tightness of the sleeve with the shaft during use is improved.
Description
Technical field
The utility model relates to mechanical fitting field, relates in particular to a kind of lining.
Background technique
In the time that machinery is moved, axle High Rotation Speed, in order to improve the stability of axle, avoids axle because frictional heat causes wearing and tearing, improves the working life of axle, and all a lining is fixed in axle outside again, and axle is protected.Lining is the conventional parts that prevent axle wearing and tearing in current industry equipment field, and the internal face majority of current lining is a continuous surface, when use, area of contact between lining internal face and rotating shaft is larger, and friction is large, weares and teares comparatively serious, working life is short, and the replacement cycle is shorter.
Model utility content
The purpose of this utility model has been to provide a kind of rational in infrastructure, wear and tear little, lubricity good, the lining of long service life.
The technical solution adopted in the utility model is as follows to achieve these goals:
A kind of lining, comprise bush body cylindraceous, described bush body inwall is provided with toroidal cavity radially and the vertical diameter axial notch to toroidal cavity, bush body sidewall is provided with oil hole, described oil hole is communicated with toroidal cavity, and described bush body two ends are provided with seal groove.
Described toroidal cavity has two, is arranged in parallel.
Described axial notch has four, is arranged in parallel.
Described toroidal cavity and the cross section of axial notch are semicircle.
Described toroidal cavity is identical with the degree of depth of axial notch.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is by the axial notch to toroidal cavity at toroidal cavity radially of lining inwall setting and vertical diameter, can effectively reduce the area of contact of lining inwall and between centers, reduce the frictional force of lining and between centers, reduce to a certain extent lining wearing and tearing in use, thereby extended the working life of lining.On lining sidewall, be provided with oil hole simultaneously, the convenient lubricant oil that adds, lubrication effect is good.Simultaneously be provided with seal groove at bush body two ends, when improving lining and using and the sealing of axle.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is left view of the present utility model.
Embodiment
Structure embodiment and accompanying drawing are further described the utility model below.
Referring to accompanying drawing, a kind of lining, comprise bush body 1 cylindraceous, described bush body 1 inwall is provided with toroidal cavity 2 radially and the vertical diameter axial notch 3 to toroidal cavity 2, toroidal cavity 2 has two, be arranged in parallel, axial notch 3 has four, be arranged in parallel, the cross section of toroidal cavity 2 and axial notch 3 is semicircle, and the degree of depth is identical, and described bush body 1 sidewall is provided with oil hole 4, described oil hole 4 is communicated with toroidal cavity 2, and described bush body 1 two ends are provided with seal groove 5.When use, because toroidal cavity 2 radially of lining inwall setting and vertical diameter are to the axial notch 3 of toroidal cavity, the area of contact of lining inwall and between centers obviously reduces, the frictional force of lining and between centers reduces, reduce to a certain extent lining wearing and tearing in use, thereby extended the working life of lining.While needs, add lubricant oil by the oil hole 4 on lining sidewall in toroidal cavity 2, when rotation, lubricant oil can flow to axial notch, and it is convenient to add, and time saving and energy saving, lubrication effect is good.
Claims (5)
1. a lining, comprise bush body cylindraceous, it is characterized in that: described bush body inwall is provided with toroidal cavity radially and the vertical diameter axial notch to toroidal cavity, bush body sidewall is provided with oil hole, described oil hole is communicated with toroidal cavity, and described bush body two ends are provided with seal groove.
2. lining according to claim 1, is characterized in that: described toroidal cavity has two, is arranged in parallel.
