Technical Field
The present invention relates to a shaft sleeve, and more particularly, to a sliding shaft sleeve having a long durability and a long life.
Background
The sliding shaft sleeve is a cylindrical mechanical part sleeved on the rotating shaft and is a component of the sliding bearing. Typically, the sleeve is an interference fit with the bearing seat and a clearance fit with the shaft. Partial shaft sleeve can be in its wall trompil in order to reach the function of self-lubricating, and the downthehole graphite post that fills in to reach the effect of self-lubricating. However, when the surface of the graphite column is worn to be smoother, the self-lubricating effect is gradually lost, the use is limited, and the overall effect is not good. Accordingly, the invention provides a sliding shaft sleeve which is durable and has long service life.
Disclosure of Invention
The present invention is directed to overcome the above-mentioned deficiencies of the prior art and to provide a durable and long-life sliding bush, which has a self-lubricating characteristic and is durable and long-life.
In order to solve the technical problem, the invention aims to realize that: the invention relates to a durable and long-life sliding shaft sleeve which comprises an inner sleeve, wherein a plurality of graphite columns are embedded in the inner sleeve, an outer sleeve is arranged on the inner sleeve, a bushing is arranged between the outer sleeve and the inner sleeve, bosses which are matched with the graphite columns one by one are distributed on the inner wall surface of the bushing, the bosses are abutted against the graphite columns, the bushing is formed by splicing at least three arc-shaped lining plates which extend along the axial direction of the bushing, an elastic body is arranged between every two adjacent arc-shaped lining plates, and adjusting screws with end portions respectively abutted against the arc-shaped lining plates are in threaded connection with.
The invention is further configured to: and positioning grooves for embedding the end parts of the elastic bodies are respectively formed in two sides of the arc-shaped lining plate.
The invention is further configured to: the elastic body is a compression spring.
The invention is further configured to: the adjusting screw is a set screw buried in the outer sleeve.
The invention is further configured to: the lining is formed by splicing four arc lining plates which extend along the axial direction of the lining.
In conclusion, the invention has the following beneficial effects: according to the durable long-life sliding shaft sleeve, the adjusting screw is screwed in, so that the adjusting screw pushes the arc-shaped lining plate, the boss pushes the graphite column, the graphite column is pushed out of the inner wall surface of the inner sleeve in a micro-scale manner, self-lubrication is formed between the graphite column and the shaft body again, the service life is prolonged, and the sliding shaft sleeve is durable, reliable, complete in overall function and high in practicability.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
In order that those skilled in the art will better understand the novel teachings of the present invention, preferred embodiments of the present invention are described below with reference to specific examples, but it should be understood that these descriptions are only intended to further illustrate the features and advantages of the present invention, and not to limit the patent claims of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention will be further described with reference to the accompanying drawings and preferred embodiments.
Example 1
Referring to fig. 1, the durable long-life sliding shaft sleeve that this embodiment relates to, including inner skleeve 1, inlayed a plurality of graphite columns 2 on the inner skleeve 1, be equipped with outer sleeve 3 on the inner skleeve 1, outer sleeve 3 with be equipped with bush 4 between inner skleeve 1, the internal face cloth of bush 4 have with the boss 5 of 2 matches one by one of graphite columns, the 5 butt of boss graphite column 2, bush 4 comprises four petals along 6 amalgamations of its axial extension's arc welt, adjacent two be equipped with elastomer 7 between arc welt 6, threaded connection has the adjusting screw 8 of tip butt arc welt 6 respectively on the outer skleeve 3.
Preferably, the elastic body 7 is a compression spring.
Further, the adjusting screw 8 is a set screw embedded in the outer sleeve 3.
In this embodiment, the adjusting screw 8 is further screwed into the outer sleeve 3, so that the arc-shaped lining plates 6 forming the lining 4 are gathered towards the central axis of the inner sleeve 1, the boss 5 extrudes the graphite column 2, and the graphite column 2 is properly pushed forwards, so that the graphite column 2 is slightly pushed out of the inner wall surface of the inner sleeve 1 to form contact with the shaft body, and a self-lubricating effect is achieved.
And in the process that the arc-shaped lining plates 6 converge towards the central axis of the inner sleeve 1, the distance between every two adjacent arc-shaped lining plates 6 is reduced, the elastic body 7 (namely, the compression spring) is compressed, and the arc-shaped lining plates 6 are kept not to deviate.
The adjusting screw 8 is a set screw and is embedded in the outer sleeve 3, so that no convex part is arranged on the outer surface of the sliding shaft sleeve, and the subsequent installation is convenient.
Example 2
Referring to fig. 1, in addition to embodiment 1, the durable and long-life sliding shaft sleeve according to the present embodiment is further configured such that positioning grooves 9 into which the end portions of the elastic bodies 7 are inserted are respectively opened at both sides of the arc-shaped liner 6. Through the arrangement of the positioning groove 9, the elastic body 7 is used for positioning and mounting, and the position deviation of the elastic body when being extruded is avoided.
According to the durable long-life sliding shaft sleeve, the adjusting screw is screwed in, so that the adjusting screw pushes the arc-shaped lining plate, the boss pushes the graphite column, the graphite column is pushed out of the inner wall surface of the inner sleeve in a micro-scale manner, self-lubrication is formed between the graphite column and the shaft body again, the service life is prolonged, and the sliding shaft sleeve is durable, reliable, complete in overall function and high in practicability.
