A threaded rod 24 is rotatably connected to the side surface of the clamping plate 23. A clamping plate 26 is threadedly connected to the surface of the threaded rod 24. One end of the threaded rod 24 penetrates through the outer bearing ring 1. Under the action of the threaded rod 24, the clamping plate 26 and the clamping plate 23 can clamp the convex block 22 tightly together, so that the outer bearing rings 1 can be combined to form a complete outer bearing ring 1 of the bearing. When the bearing needs to be used, the steel balls 5 are placed between the outer bearing ring 1 and the inner bearing ring 4, and the two outer bearing rings 1 and the inner bearing ring 4 are combined to form a complete bearing and placed inside the agricultural machinery for use. A sliding rod 25 is fixedly connected to the side surface of the clamping plate 23. The clamping plate 26 is slidably connected to the surface of the sliding rod 25. Under the action of the sliding rod 25, the clamping plate 26 will not rotate with the rotation of the threaded rod 24. A gasket 28 is arranged on the side surface of the outer bearing ring 1. The gasket 28 is a rubber pad. Under the action of the gasket 28, when the two outer bearing rings 1 are combined, there will be no phenomenon of rigid collision, avoiding the phenomenon that the service life is reduced due to the rigid collision of the outer bearing ring 1. A round rod 29 is fixedly connected to the side surface of the outer bearing ring 1. A round groove 27 is opened on the side surface of the outer bearing ring 1. The round rod 29 is inserted into the inside of the round groove 27. The gasket 28 is sleeved on the surface of the round rod 29. Under the action of the round rod 29 and the round groove 27, the outer bearing rings 1 can be initially clamped together, avoiding the phenomenon of misalignment during splicing. When the bearing needs to be disassembled, the threaded rod 24 is rotated, so that the clamping plate 26 moves away from the clamping plate 23 under the cooperation of the sliding rod 25, and then the convex block 22 is separated. The threaded rod 24 is rotated, so that the clamping plate 23, the clamping plate 26 and the convex block 22 are separated, and then the outer bearing rings 1 are separated, and then the bearing is disassembled. When installation is required, after placing half of the bearing in the appropriate position, the other half of the bearing is clamped together through the round rod 29 and the round groove 27. The gasket 28 is sleeved on the surface of the round rod 29 for positioning. The clamping plate 23 is fitted with the convex block 22. The threaded rod 24 is screwed, so that the clamping plate 26 moves towards the position of the clamping plate 23 under the cooperation of the sliding rod 25, and then the two outer bearing rings 1 of the bearing are fixed together, thus achieving the function of convenient disassembly.

A screw rod 32 is rotatably connected inside the rectangular groove 31. A slider is threadedly connected to the surface of the screw rod 32. A trapezoidal block 34 is fixedly connected to the side surface of the slider. Under the action of the trapezoidal block 34, the diameter of the bearing can be finely adjusted, so that it can be fixed more firmly inside the agricultural machinery. A fixing rod 33 is fixedly connected inside the rectangular groove 31. A slider is slidably connected to the surface of the fixing rod 33.

The cushion block 35 is a sponge block. Under the action of the cushion block 35, the trapezoidal block 34 will not directly contact the agricultural machinery, avoiding the phenomenon of rigid contact. A groove is formed on one side of the trapezoidal block 34 close to the outer bearing ring 1. A ball 36 is rotatably connected inside the groove. Under the action of the ball 36, the trapezoidal block 34 can move more smoothly on the surface of the outer bearing ring 1. When the bearing is installed inside the agricultural machinery and it is found that the bearing cannot be fixed firmly inside the agricultural machinery, turn the screw rod 32, so that the slider drives the trapezoidal block 34 to move under the cooperation of the fixing rod 33, and then the trapezoidal block 34 is clamped between the bearing and the agricultural machinery, so that the bearing is firmly fixed inside the agricultural machinery. Under the action of the ball 36, the trapezoidal block 34 can move more smoothly on the surface of the outer bearing ring 1. Under the action of the cushion block 35, the trapezoidal block 34 will not directly contact the agricultural machinery, avoiding the phenomenon of rigid contact, and thus achieving the effect of adjusting the bearing.

When the bearing needs to be disassembled, the threaded rod 24 is rotated, so that the clamping plate 26 moves away from the clamping plate 23 under the cooperation of the sliding rod 25, and then the convex blocks 22 are separated. The threaded rod 24 is rotated to separate the clamping plate 23, the clamping plate 26 and the convex blocks 22, and then the bearing outer ring 1 is separated, and then the bearing is disassembled. When installation is required, after placing half of the bearing in the appropriate position, the other half of the bearing is clamped together through the round rod 29 and the round groove 27, the gasket 28 is sleeved on the surface of the round rod 29 for positioning, the clamping plate 23 is fitted with the convex block 22, and the threaded rod 24 is screwed to make the clamping plate 26 move towards the position of the clamping plate 23 under the cooperation of the sliding rod 25, and then the two bearing outer rings 1 are fixed together, thus achieving the effect of convenient disassembly. When the bearing is installed inside the agricultural machinery and it is found that the bearing cannot be firmly fixed inside the agricultural machinery, the screw 32 is screwed to make the slider drive the trapezoidal block 34 to move under the cooperation of the fixed rod 33, and then the trapezoidal block 34 is clamped between the bearing and the agricultural machinery, and then the bearing is firmly fixed inside the agricultural machinery. Under the action of the ball 36, the trapezoidal block 34 can move more smoothly on the surface of the bearing outer ring 1. Under the action of the cushion block 35, the trapezoidal block 34 does not directly contact the agricultural machinery, avoiding the phenomenon of rigid contact, and thus achieving the effect of adjusting the bearing.
