Description

Technical Field

[0001] The utility model relates to the technical field of bushings, in particular to a bushing that is convenient for loading and unloading. Background Technique

[0002] A bushing is a mechanical component, usually used between a shaft and a bearing, or between a shaft and other components. The bushing can reduce the direct contact between the shaft and the bearing seat or hole, thereby reducing wear and extending the service life of the shaft and the bearing seat. Since the bushing is easier to install and replace relative to the shaft, the bushing can make the assembly of the shaft more convenient, and it is usually more economical to replace the bushing during maintenance than to replace the entire shaft or bearing seat.

[0003] At present, a part of the existing bushing designs adopt a press-fitting installation method. Although the press-fitting bushing is easy to install, once installed, it is difficult to disassemble during later replacement or maintenance, which is likely to cause damage to the shaft or the bushing. Moreover, the press-fitting installation requires a large force, which may cause deformation or damage to the bushing.

[0004] Therefore, those skilled in the art have provided a bushing that is convenient for loading and unloading to solve the problems raised in the above background technique. Content of the Utility Model

The fixed plates 304 are rotatably connected to the adjusting plate 301. A rotating plate 306 is provided on one side of the adjusting plate 301. A rotating seat 310 is fixedly connected to one side of the adjusting plate 301. The rotating seat 310 is rotatably connected to the rotating plate 306. A first magnet 307 is fixedly connected to the side of the rotating plate 306 away from the adjusting plate 301 at the rear end. Placing grooves 308 are opened at the four corners of the outer periphery of one side of the outer sleeve body 1. A second magnet 309 is fixedly connected to the inner bottom of the placing grooves 308. A rubber pad 305 is fixedly connected to the side of the adjusting plate 301 away from the fixed plate 304;

[0039] Specifically, the adjustment structure 3 facilitates the installation of the bushing and the bearing housing. The lubrication structure 4 facilitates the injection of lubricating oil between the bushing and the shaft. The fixed plate 304 facilitates the rotation of the connecting block 303 between the two fixed blocks 302 after the adjustment plate 301 moves, thereby changing the height of the adjustment plate 301 so that it can be better placed inside the bearing housing. The rotating plate 306 facilitates its rotation during loading and unloading, thereby driving the first magnet 307 to move. The rotating seat 310 facilitates the rotation of the rotating plate 306. The second magnet 309 facilitates restricting the position of the rotating plate 306 when it comes into contact with the first magnet 307, thereby fixing the adjustment plate 301. The rubber pad 305 facilitates increasing the friction between the adjustment plate 301 and the inner wall of the bearing housing.

[0040] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the lubrication structure 4 includes two oil storage channels 401. Oil outlets 402 are provided at the four corners inside the oil storage channels 401. The oil outlets 402 are connected to the oil storage channels 401 in a through manner.
