Description

Technical Field

[0001] The utility model specifically relates to a friction welding track roller. Background Art

[0002] At present, with the accelerated pace of construction, the use of excavators has become more and more frequent. The use of excavators has saved people a lot of labor and greatly accelerated the speed of people's construction. When the excavator is in use, the excavator's track wheels are an important part of the excavator. When the excavator's track wheels are in use, the excavator's track wheels are prone to wear under high-intensity operation, and the wear of the track wheels will cause the excavator to be unable to be used. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a friction welding track roller.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a friction welding supporting roller, including a wheel body, end covers are arranged at both ends of the wheel body, a support shaft is movably connected between the two end covers, the side walls of the two end covers are arranged with bearings, the outer side walls of the two bearings are arranged with floating oil seals, the floating oil seal is located between the end cover and the wheel body, an oil filling hole is opened at one end surface of the end cover, the oil filling hole is connected to the floating oil seal, and an oil pressure assembly is detachably installed in the oil filling hole.

[0005] Preferably, the oil pressure assembly comprises a pressure head and a pressure plate, and a compression spring is connected between the pressure head and the pressure plate.

[0006] Preferably, the pressure head and the oil filling hole are threadedly connected.

[0007] Preferably, O-rings are provided on both sides of the floating oil seal.

[0008] Preferably, the wheel body is formed by welding two wheel support members.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the friction welded track roller improves the load-bearing capacity of the wheel body, prolongs the ultimate service life of the track roller, and at the same time makes the track roller less likely to deform, crack or break.
