摘　　要：装载机驱动桥轮边减速机构主要存在行星轮的跨置和悬臂支承方式,分析了这两种支承方式下的系统变形导致的齿轮啮合错位,利用Romax传动系统设计分析软件,对齿轮副进行了TCA分析,说明了系统变形导致的齿轮载荷分布和强度差异,提出了行星轮跨置支承的优势,在考虑齿轮强度时,除齿轮自身宏观参数之外,还需从系统角度考虑机构变形的影响。Wheel loader axle final drive have cross support and cantilever support structure, this paper compare this two structures on gear mesh misplacement caused by the system deformation. Through TCA method by using romax software, the gear load distribution and strength have been presented , there is result that cross support is better.This paper offer that system deformation shall be considered in gear strength besides the gear parameter.
