Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figure 1 - Figure 4 shown, the present invention provides a bearing component capable of observing the grease filling amount, including an outer ring 9 of the bearing. An inner ring 8 of the bearing is arranged inside the outer ring 9 of the bearing. A cage 19 is arranged in the sandwich between the outer ring 9 of the bearing and the inner ring 8 of the bearing. A first end cover 1 is installed at one end of the outer ring 9 of the bearing, and a second end cover 6 is installed at the other end of the outer ring 9 of the bearing. One end of the inner ring 8 of the bearing is rotatably connected to the middle of the second end cover 6. First oil filling ports 5 are opened on the outer surface of the outer ring 9 of the bearing and on one side of the second end cover 6. A positioning collar 12 is fixedly connected to one end of the outer ring 9 of the bearing. A sealing ring 13 is fixedly connected to one side of the positioning collar 12. The sealing ring 13 is installed at one end of the first end cover 1. Bearing pads 3 are arranged at both ends of the cage 19. One side of the bearing pad 3 is fixedly connected to the inner side of the outer ring 9 of the bearing. Grease cups 4 are installed at one ends of the first oil filling port 5 and the second oil filling port 7.

[0024] A second oil filling port 7 is provided on one side of the second end cover 6, and a first oil filling port 5 is provided on the outer surface of the outer ring 9 of the bearing. Grease is filled into the interior of the outer ring 9 of the bearing through the second oil filling port 7 and the first oil filling port 5. An oil cup 4 is installed at one end of the second oil filling port 7 and the first oil filling port 5, which can be used to isolate external dust. A first end cover 1 is provided at one end of the outer ring 9 of the bearing. The first end cover 1 is hermetically connected to one end of the outer ring 9 of the bearing through a positioning collar 12 and a sealing ring 13, completely isolating the interior of the outer ring 9 of the bearing from the external air and preventing dust from entering and contaminating the grease. At the same time, the first end cover 1 is made of transparent glass material, and while isolating the external air, the grease filling amount inside the first end cover 1 can be observed to prevent overheating caused by excessive grease and increased running resistance, and insufficient bearing lubrication and bearing wear caused by too little grease.

[0025] Embodiment 2: As Figure 1 and Figure 4 shown, a fixed sleeve 11 is fixedly connected to the outer surface of the outer ring 9 of the bearing. A rotating block 14 is provided at one end of the fixed sleeve 11, and a connecting rod 2 is fixedly connected to the middle of the rotating block 14; a sliding groove 15 is provided on the outer surface of the rotating block 14, and a sliding convex ring 16 is rotatably connected to the inside of the sliding groove 15.

[0026] The overall effect achieved by the entire embodiment is that when the pressing plate 10 is rotated, the torsion spring 17 will generate a deformation force to prevent the pressing plate 10 from moving. By contacting the flexible pressing block 18 with one side of the first end cover 1, and the flexible pressing block 18 is made of an elastic material, the first end cover 1 and the outer ring 9 of the bearing can be tightly pressed, improving the sealing effect of the first end cover 1. When the first end cover 1 needs to be disassembled, the pressing plate 10 can be rotated, the connecting rod 2 and the rotating block 14 rotate, the sliding convex ring 16 rotates inside the sliding groove 15, driving the torsion spring 17 to generate a deformation force, and rotating the pressing plate 10 and the flexible pressing block 18 until they are separated from the first end cover 1 to disassemble the first end cover 1.

[0027] Usage method and working principle of the present device: When the pressing plate 10 is rotated, the torsion spring 17 generates a deformation force to prevent the pressing plate 10 from moving. By contacting the flexible pressing block 18 with one side of the first end cover 1, the flexible pressing block 18 is made of an elastic material, which can press the first end cover 1 between the first end cover 1 and the outer ring 9 of the bearing. The first end cover 1 is hermetically connected to one end of the outer ring 9 of the bearing through the positioning collar 12 and the sealing ring 13. At the same time, the first end cover 1 is made of transparent glass material, which can observe the filling amount of the grease inside the first end cover 1.
