[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Spherical plain bearings are a type of spherical sliding bearings that can rotate and swing at any angle during movement. Because of their large load capacity, impact resistance, corrosion resistance, wear resistance, self-alignment, and good lubrication, some rail vehicle anti-roll torsion bars use them to replace rubber joint structures.
[0003] The performance and service life of the spherical bearing are greatly affected by the sealing effect. Once the seal fails, dust enters or lubricating grease is lost, the wear of the spherical bearing will be accelerated. Therefore, the bearing seal is an important component of the structure. In the prior art, during the transportation and assembly of the anti-roll torsion bar with the vehicle body, the excessive swing of the connecting rod will collide with the torsion arm. If it is not properly protected, the bearing seal will be damaged, thereby reducing the service life of the bearing. The practicability is insufficient. Therefore, it is necessary to redesign a torsion bar bearing for track equipment to address the above problems. Utility Model Content

[0024] The ends of the two connecting blocks 8 are fixedly connected with a connecting sleeve 9, the outer wall of the shaft sleeve 1 is fixedly installed with a connecting sleeve 11, and the outer wall of the connecting sleeve 11 is fixedly installed with multiple adjusting rods 12, and the outer wall of each adjusting rod 12 is slidably installed with a sealing sleeve 13, and the end of each adjusting rod 12 is fixedly installed with a limit plate 14 that cooperates with the sealing sleeve 13, and the inner wall of each limit plate 14 is connected to the outer wall of the sealing sleeve 13 through an adjusting mechanism. The adjusting mechanism includes an adjusting spring 15 installed on the outer wall of the adjusting rod 12, and the two ends of the adjusting spring 15 are respectively connected to the outer wall of the sealing sleeve 13 The wall and the inner wall of the limit plate 14 are elastically connected. The limit plate 14 can limit the sealing sleeve 13 to prevent it from detaching from the outer wall of the adjusting rod 12. The inner wall of the sealing sleeve 13 is provided with a mounting groove, and a sealing ring 16 is installed inside the mounting groove. A plurality of cleaning brushes 10 are fixedly installed on the inner wall of the connecting sleeve 9. Each cleaning brush 10 and the sealing ring 16 are made of vulcanized rubber.
