Abstract
A disclosed bush comprises a cylindrical bush body, the inner wall of the bush body is provided with radial annular grooves and axial grooves perpendicular to the radial annular grooves, the side wall of the bush body is provided with an oil injection hole communicated with the annular grooves, and two ends of the bush body is provided with seal grooves. By arranging the radial annular grooves and the axial grooves perpendicular to the radial annular grooves at the inner wall of the bush, the contact area of the bush inner wall and a shaft is effectively reduced, the frictional force between the bush and the shaft is reduced, wearing of the bush during usage is reduced to a certain degree, and the service life of the bush is prolonged. Also by arranging the oil injection holes at the side wall of the bush, lubricating oil is facilitated to be added, the lubrication effect is good. By arranging the seal grooves at two ends of the bush body, the leakproofness between the bush and the shaft during usage is improved.
Description
Technical field
The present invention relates to mechanical fitting field, relate 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.
Summary of the invention
The object of this invention is to provide a kind of rational in infrastructure, wear and tear little, lubricity good, the lining of long service life.
The technical solution used in the present invention 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, beneficial effect of the present invention is as follows:
The present invention 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 invention;
Fig. 2 is sectional view of the present invention;
Fig. 3 is left view of the present invention.
Embodiment
The invention will be further described for structure embodiment and accompanying drawing 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.
3. lining according to claim 1, is characterized in that: described axial notch has four, is arranged in parallel.
