Detailed Description
The principles and features of the present application are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the application and are not to be construed as limiting the scope of the application.
The embodiment of the application discloses a slewing bearing for wading.
Referring to fig. 1-2, a slewing bearing for wading comprises a slewing inner ring 1 and a slewing outer ring 2, wherein a sealing belt 3 is arranged at the top end of the slewing inner ring 1, one end of the sealing belt 3 is abutted against the outer wall of the upper end part of the slewing outer ring 2, a sealing ring 4 is arranged at the lower end part of the slewing inner ring 1, the sealing ring 4 comprises an upper sealing lip 41 and a lower sealing lip 42, the inner side surface of the upper sealing lip 41 is abutted against the side surface of the bottom end of the slewing outer ring 2, and the inner side surface of the lower sealing lip 42 is abutted against the bottom surface of the slewing outer ring 2.
One end of the sealing ring 4 adopts a double-lip structure to cooperate with protection, the upper sealing lip 41 mainly protects the inside, and the lower sealing lip 42 mainly protects the outside, so that the protection performance of the sealing ring 4 is further enhanced, sand and water are not easy to enter the slewing bearing raceway when the excavator is in wading operation, and good lubricating grease in the slewing bearing is not easy to run off; the sealing strip 3 inside adopts the single lip protection of vertical installation, and the compressive force is big, anti-drop effect is better.
The upper seal lip 41 and the lower seal lip 42 are made of elastic materials, and when the upper seal lip 41 and the lower seal lip 42 are abutted against the slewing outer ring 2, the upper seal lip 41 and the lower seal lip 42 tend to approach each other under the action of elastic force. The sealing ring 4 can be tightly attached to the rotary outer ring 2 during working, and the sealing effect is better.
The sealing belt 3 and the sealing ring 4 are made of rubber materials. The better rubber material is selected, the roughness of the friction surface of the sealing belt 3 and the sealing ring 4 is controlled, the abrasion loss of the sealing belt 3 and the sealing ring 4 caused by long-time friction is reduced, and the service lives of the sealing belt 3 and the sealing ring 4 are prolonged.
