[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Simply put, bearings are key components between two relatively moving objects that play a role in reducing friction, reducing wear, transmitting force and torque, and maintaining the normal working position and rotation accuracy of the shaft.

Manual intervention is required to remove the bearing from the equipment and manually add new lubricating oil, which is time-consuming and labor-intensive. Therefore, a sliding bearing with a lining structure is proposed to address the above problem. Utility Model Content

[0033] Working principle: When the bearing is in operation, the inner ring 1 will rotate with the connected device, thereby driving the ball 6 and the retainer 5 to rotate inside the inner ring 1 and the outer ring 3. When lubricating oil needs to be added to the inside of the bearing, the rotating ball 6 will pass through the steel ball 201 connected to the inner ring 1, which will squeeze the steel ball 201 and press the steel ball 201 into the inner ring 1. The squeezed steel ball 201 will move toward the inner ring 1, thereby squeezing the pressing pump 203. The pressing pump 203 will extract the lubricating oil in the lubricating oil storage tank 202 through the connecting pipe 204. The pressing pump 203 is an existing device. There is no need to elaborate on the arrangement. The extracted lubricating oil will be squeezed out from the L-shaped rubber outlet pipe 205, and the squeezed lubricating liquid will flow out through the rubber outlet groove 207. The flowing lubricating oil will be spread on the contact surface of the entire bearing through the rotating steel ball 201, ensuring that the lubricating oil can be evenly distributed inside the bearing, thereby maintaining a good lubrication state between the ball 6 and the inner and outer rings 3. The rebound force of the pressing pump 203 will drive the steel ball 201 to reset, and the limit groove 206 can provide space for the L-shaped rubber outlet pipe 205 to ensure the normal operation of the pressing pump 203. When it is necessary to heat the lubricating oil storage tank 202 When the lubricating oil is added, the user disengages the first clamping block 12 from the elastic sheet 15 and the two second clamping blocks 16 through the second limiting block 10, and the sealing cover 8 can be opened. When the sealing cover 8 is opened, the rotating shaft 17 will be driven to rotate, thereby stretching the torsion spring 18. The deformation of the torsion spring 18 can provide power for closing the sealing cover 8. After the sealing cover 8 is opened, the user uses an external tool to add the lubricating oil into the lubricating oil storage tank 202 through the rubber inlet pipe 7. After the addition is completed, when the user closes the sealing cover 8, the sealing gasket 20 will contact with the groove 19, and the sealing gasket 20 has good sealing performance. and elasticity, and can fit tightly to the surface of the groove 19 when under pressure to form an effective barrier. When the first card block 12 is inserted between the elastic sheet 15 and the two second card blocks 16, the elastic sheet 15 is squeezed and deformed, and at the same time drives the two second card blocks 16 to move along the surface of the first card block 12. As the first card block 12 continues to be inserted, the two second card blocks 16 will move to a position where they can lock the first card block 12. When the first card block 12 is locked, the elastic sheet 15 returns to its original state, thereby forming a stable locking state, which can prevent the sealing cover 8 from being accidentally opened.
