支重轮是履带式工程机械底盘四轮一带中的一种,它的主要作用是支撑着挖掘机与推土机的重量,让履带沿着轮子前进。基于精密的配件,细心的热处理和耐磨的油封系统,良好的内部油循环系统,保证了轮子的使用寿命。锻造处理制造的轮壳获得卓越的内部材质纤维流分布。

1. 轮体:采用淬透性好的40Mn2圆钢材料经锻造而成;调质+中频表面淬火的热处理工艺,保证其强度和耐磨性能。

2.轴:采用45#圆钢材料,调质+中频表面淬火的热处理工艺,表面硬度HRC52-60,硬化层深度可达3-6mm,综合机械性能优良。

3.浮动油封:采用高铬高钼合金,硬度HRC65-72,工作亮带粗糙度0.1um-0.2um。

4.O形密封圈:采用丁烯和丙烯腈经共聚而成的丁腈橡胶为原料生产而成,具有更好的耐油性和耐高温。

支重轮表面硬度为HRC50-56,深度8mm-12mm。
