摘　　要：轮边减速器作为重型或新能源车辆重要的减速增扭传动结构之一,其箱体是齿轮传动系统内部载荷和车架连接外部载荷的重要承载体,箱体结构设计合理和强度性能满足是轮边减速器平稳运行的重要保证。基于箱体三维几何结构和有限元分析方法,建立集“模型-强度评判-运转”的箱体结构分析方法,综合研究了箱体的结构强度及密封性。结果表明,采用组合计算的载荷和强度评判准则下的箱体具有足量的设计强度和刚度,可以支撑内场传动系统的平稳运行和抵抗外载荷作用变形;足量的螺栓分布和合适的螺栓型号可以保证箱体结合面接触面均匀分布,且不发生漏油现象;箱体试验结果与理论分析基本吻合。提出的结构强度分析方法为箱体的结构设计提供了技术参考。The wheel reducer is one of important transmission structures of heavy or new energy vehicles for increased torque and reduces speed.The gearbox mainly carries the internal load from gear transmission and the external load from frame connection.The reasonable design and strength performance of the gearbox are important guarantees for the smooth operation of the wheel reducer.Based on the three-dimensional geometric structure of the gearbox and the finite element analysis method,a structural strength analysis method integrating"model-strength evaluation-running"is established and the structural strength of the gearbox is investigated comprehen⁃sively.The results show that the box under the load and strength evaluation criteria of combined calculation has sufficient design strength and stiffness,which can support the smooth operation of the infield transmission system and resist the deformation caused by external load.The distributed contact area of the joint surface of gearboxes is ensured by the sufficient distribution and strength of bolts,and no oil leakage occurs in the gearbox.The operation⁃al experiment result of gearboxes is in agreement with the above theoretical analysis.The proposed structural strength analysis method provides a technical basis for the structural design of the gearbox.
