The R60 track track roller is an important load-bearing component of the HYUNDA excavator chassis. It consists of track wheels, support shafts, left and right support seats, and seal components. The supporting shaft is fixed on the trolley frame through left and right supporting seats. The press-fitted shaft sleeves in the holes of the wheel body cooperate with the supporting shaft to rotate. A sealing component is installed between the rotating wheel body and the fixed left and right supporting seats to maintain the supporting shaft. Sealing with lubricating oil in shaft sleeve and other parts.
The sealing assembly is composed of a pair of double-conical metal material sealing rings and two nitrile rubber fixed compression rings.
The rubber rings are respectively installed in the sealing seat openings of the wheel body and the support seat. Since the metal seal ring is pressed by the rubber ring to ensure that the annular blades are tightly engaged during rotation, the seal is a floating seal type.
R60 track roller material
60R60 track roller wheel materials are generally 50Mn, 40Mn2, etc. The main process is casting or forging, machining, and then heat treatment. The hardness of the surface of the wheel after quenching should reach HRC45 ~ 52 to increase the wear resistance of the wheel surface. The processing precision of roller axles is relatively high. Generally, CNC machine tools are required to meet the requirements. The material is more than 40Mn2. After processing, it is also required to be quenched and heat treated, and the hardness reaches about HRC42.
