The supporting wheel is one of the four wheels of the crawler construction machinery chassis. Its main function is to support the weight of the excavator and the bulldozer, so that the crawler can advance along the wheel. Based on precision accessories, careful heat treatment and wear-resistant oil seal system, good internal oil circulation system, ensure the service life of the wheel. The forging treatment manufactures the wheel housing to obtain superior internal material fiber flow distribution. 1. Wheel body: 40Mn2 round steel material with good hardenability is forged; Quenching and tempering + medium frequency surface quenching heat treatment process to ensure its strength and wear resistance. 2. Shaft: using 45# round steel material, tempering and quenching + medium frequency surface quenching heat treatment process, surface hardness HRC52-60, hardening layer depth up to 3-6mm, excellent comprehensive mechanical properties. 3. Floating oil seal: using high chromium and high molybdenum alloy, hardness HRC65-72, working bright band roughness 0.1um-0.2um. 4. O-ring: The use of butene and acrylonitrile by copolymerization of nitrile rubber as raw material production, with better oil resistance and high temperature resistance. The surface hardness of the supporting wheel is HRC50-56, and the depth is 8mm-12mm. Note: Our company can be customized according to user requirements and specific models.
