The second radial force roller set 17 also controls the radial clearance of the wheel 19 and is able to withstand greater radial forces. The first radial force roller set 16 and the second radial force roller set 17 are distributed left and right, so that the normal rotation of the wheel 19 body can be realized. A wedge groove is formed at the connection of the inner ring 14 and the outer ring 15 for mounting the third axial force roller set 18. The third set of axial force rollers 18 controls the axial clearance of the wheel 19 and is capable of withstanding greater axial forces. The outer side of the inner ring is sleeved with wheels 19. The third set of axial force rollers 18 is square in cross section. The third axial force roller set 18 is placed so as to increase its axial bearing force so that no looseness occurs in the axial direction, and the opposite corners of the square can function to support the wheels 19, improving structural stability. The two opposite vertex angles of the third set of square axial force rollers 18 respectively abut the bottom of the wedge-shaped groove and the inner wall of the wheel 19. Balls are provided between one of the two opposite corners of the third set of axial force rollers 18 and the inner wall of the wheel 19. Balls are provided between the other of the two opposing top corners of the third set of axial force rollers 18 and the bottom of the wedge-shaped groove. The balls play a role in supporting the device in a radial rolling manner while supporting the wheels 19, so that the connection between the wheels 19 and the device is smoother, and the radial stability of the device is ensured. The balls can define the wheel 19 in the axial direction. A seal ring 20 and a mounting groove 22 for mounting an oil seal 21 are formed at the connection of the inner ring 14 and the outer ring 15 to the wheel 19. The mounting groove 22, the first groove, the second groove and the wedge-shaped groove are mutually communicated to form a through groove together. The seal ring 20 is located between the oil seal 21 and the inner ring. Through oil blanket 21 and sealing washer 20, realized double seal, thoroughly solved dustproof effect poor, the problem of lubricating oil seepage. The middle part of the fixed end cap 12 is provided with a threaded cavity 122, and the threaded cavity 122 is used for installing the oil nozzle 23.
