XDE400轮毂驱动单元集成设计模型

400吨级矿用自卸车轮毂驱动的大扭矩高承载（输出扭矩1.6×10^6 Nm，承重630 T）及体积空间（齿圈最大径向1143mm）受限等特点，轮毂驱动单元设计采用集成化设计方法，建立模型包含电机结构：电机定子，转子，电机壳体，电机轴等,减速机结构：结构件参数、行星排参数、花键参数、轴承类型、密封类型；根据轮毂驱动在主机上的应用，设置输入输出、径向力等信息，并明确行星齿轮传动与电机、机架、轮胎及制动器连接界面约束关系及特征状态空间。在有限元中，对机架、轮毂、壳体等部位进行多目标拓扑优化分析，达到减速机高刚度轻量化的设计要求。在多工况复合载荷谱下，轴承寿命不低于50000小时，齿轮、轴等部件的安全系数大于1，实现驱动行星齿轮传动系统集成设计。 数据量43.8MBFeaturing high torque and high load capacity (output torque: 1.6×10^6 Nm, load-bearing capacity: 630 T) of the 400-ton-class mining dump truck hub drive, as well as limited installation space (maximum radial dimension of the gear ring: 1143 mm), the hub drive unit adopts an integrated design methodology. The established model covers the motor structure including motor stator, rotor, motor housing, motor shaft, etc., and the reducer structure including structural component parameters, planetary gear train parameters, spline parameters, bearing types and seal types. Based on the application of the hub drive on the main machine, parameters such as input/output and radial force are configured, and the constraint relationships and characteristic state spaces of the connection interfaces between the planetary gear transmission and the motor, frame, tire and brake are clarified. Finite element analysis (FEA) is conducted to perform multi-objective topological optimization on components such as the frame, hub and housing, so as to meet the design requirements of high stiffness and lightweight for the reducer. Under the composite load spectrum of multiple working conditions, the bearing life is no less than 50000 hours, and the safety factors of components such as gears and shafts are greater than 1, thus realizing the integrated design of the driving planetary gear transmission system.
