Problems solved by technology

[0003] The existing shaft sleeve and shaft need to be lubricated multiple times in the early, middle and late stages of running-in to ensure the rotation effect of the shaft in the shaft sleeve. The operation is cumbersome and complicated, and multiple maintenances are required, which reduces work efficiency. Therefore, the present invention proposes a radially embedded self-lubricating material maintenance-free bushing that can solve the above problems

Embodiment 1

[0030] A radially embedded self-lubricating material maintenance-free bushing, including a bushing base 10, a plurality of groups of through holes 20 evenly distributed on the wall of the bushing base 10, the through holes 20 are filled with solid self-lubricating medium, the inner wall of the bushing base 10 Several groups of diversion oil grooves 30 are evenly distributed, and the diversion oil grooves 30 are filled with grease lubricant;

[0031] The solid self-lubricating medium has a microporous structure, and the solid self-lubricating medium automatically overflows a small amount of liquid lubricating oil during the heating process of the shaft sleeve for oil lubrication;

[0032] The diversion oil groove 30 is viewed as a waist-shaped groove from above, and the depth of the diversion oil groove 30 gradually decreases from the middle to both ends, until both ends of the diversion oil groove 30 extend to the inner wall of the sleeve base 10;

[0033] Both sides of the di...

Embodiment 2

[0038] Garbage ring grooves 40 are provided on the inner walls at both ends of the shaft sleeve base 10 .

[0039] Specifically, it can make the shaft sleeve and the shaft work together to isolate the garbage on the shaft body, so that the garbage on the shaft body can enter the garbage ring groove 40, avoid being squeezed into the matching gap between the shaft and the shaft sleeve, and ensure normal operation. .

Embodiment 3

[0041] Miscellaneous outlets 41 are respectively arranged on both ends of the shaft sleeve base 10, and the miscellaneous outlets 41 communicate with the garbage ring groove 40;

[0042] The garbage chute is provided with a miscellaneous discharge mechanism, which includes a connecting plate 42, an arc groove 43, an arc spring 46, a miscellaneous pushing plate 44 and a push handle 45, and the garbage ring groove 40 is far away from the miscellaneous discharge port 41 at the maximum distance. One end is provided with a connecting plate 42, and two groups of arc-shaped grooves 43 are arranged symmetrically on the end surface of the shaft sleeve base 10. The two groups of arc-shaped grooves 43 take the connecting plate 42 as a symmetrical plane, and the two sides of the connecting plate 42 are provided with miscellaneous pushing plates 44. Push miscellaneous plate 44 bottom edge and side contact with rubbish ring groove 40 inner walls, be provided with arc spring 46 between miscel...

Abstract

The invention discloses a radially embedded maintenance-free shaft sleeve made of a self-lubricating material. The maintenance-free shaft sleeve comprises a shaft sleeve base body, a plurality of sets of through holes are evenly distributed in the wall of the shaft sleeve base body, the through holes are filled with solid self-lubricating media, a plurality of sets of flow guide oil grooves are evenly distributed in the inner wall of the shaft sleeve base body, and the flow guide oil grooves are filled with grease lubricants. The through holes are filled with the graphite solid self-lubricating media, the flow guide oil grooves are filled with the grease lubricants, trace liquid lubricating oil which can automatically overflow from the microcosmic porous graphite solid self-lubricating media in the heating process is used by the shaft sleeve for oil oil lubrication on a shaft, solid lubrication, grease lubrication and oil lubrication are achieved, in the assembling and using process of the shaft sleeve, the added grease lubricants and the solid self-lubricating media falling due to abrasion can fall into the flow guide oil grooves to be stored for a long time, the lubricating media do not need to be added multiple times in the later period, maintenance is easy and convenient, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of shaft sleeves, in particular to a radially embedded self-lubricating material maintenance-free shaft sleeve. Background technique [0002] The shaft sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is an integral part of the sliding bearing. Generally speaking, the shaft sleeve and the bearing seat adopt an interference fit, while the shaft sleeve adopts a clearance fit. [0003] The existing shaft sleeve and shaft need to be lubricated multiple times in the early, middle and late stages of running-in to ensure the rotation effect of the shaft in the shaft sleeve. The operation is cumbersome and complicated, and multiple maintenances are required, which reduces work efficiency. Therefore, the present invention proposes a radially embedded self-lubricating material maintenance-free bushing that can solve the above problems. Contents of the invention [0004] The purpose...
