Technical Field
The utility model relates to a thrust wheel field specifically is an excavator thrust wheel.
Background
The thrust wheel is one of four wheels and one belt of a chassis of the crawler type engineering machine, and mainly has the function of supporting the weight of the excavator and the bulldozer and enabling the crawler to advance along the wheel. The wheel body, the thrust wheel shaft, the shaft sleeve, the sealing ring, the end cover and other related components. The thrust wheel can be divided into a single-side thrust wheel and a double-side thrust wheel; the supporting wheel for the excavator and the supporting wheel for the bulldozer are generally black paint, and the supporting wheel for the bulldozer is generally yellow paint. The material of the wheel body of the thrust wheel is generally 50Mn, 40Mn2 and the like, the main process comprises casting or forging, machining and heat treatment, and the hardness of the quenched surface of the wheel is HRC45-52 so as to increase the wear resistance of the surface of the wheel. The machining precision requirement of the thrust wheel shaft is higher, and the requirement can be met only by machining with a numerical control machine tool. The material is more than 40Mn2, and is also subjected to quenching heat treatment after processing, and the hardness reaches about HRC 42.
The side cover of the existing excavator thrust wheel is easy to wear and has poor sealing performance, so that the development of the excavator thrust wheel with the side cover which is not easy to wear and has good sealing performance is urgently needed aiming at the current situation, so that the defects in the current practical application are overcome, and the current requirements are met.
