undercarriage track rollers production process

undercarriage track rollers is used to support the weight of the tractor while rolling on the track's guide rail (rail link) or track plate surface. It is also used to limit the track and prevent lateral slippage. When the tractor turns, the undercarriage track rollers forces the track to slide on the ground. The undercarriage track rollers is often in mud, water and dust, and withstands strong impact, so it is required to seal reliably and wear the wheel ring. The following to introduce the heavy wheel production process. The structure of the undercarriage track rollers is mainly divided into the wheel body, the undercarriage track rollers shaft, the shaft sleeve, the sealing ring and the end cap. The high quality undercarriage track rollers mainly depends on its steel performance, the undercarriage track rollers body material is generally 50Mn, 40Mn2, (MN: synonymous with fierce elements), the undercarriage track rollers production process is divided into casting or forging, mechanical processing, and then heat treatment, the hardness of the wheel surface quenching reaches HRC45-52, to increase the wear resistance of the wheel surface. The processing accuracy of the undercarriage track rollers is relatively high, and generally requires CNC machine tools to process in order to meet the requirements. The material 40Mn2 is more, and the hardness reaches about HRC42.
