摘　　要：轮毂电机端盖总成单机压装效率低、工序分散。在分析轮毂电机端盖总成结构及压装工艺的基础上,设计“轴承-端盖-油封”一体式压装装置。压装装置中,轴承抓取机构利用O形圈与轴承内圈之间的摩擦力实现轴承的抓取。提出一种根据所需摩擦力大小,利用Lindley公式、经验公式等进行O形圈选型计算及沟槽设计的方法。根据仿真方案进行样机试制,结果表明:设计的轴承抓取机构能够实现轴承的稳定抓取压装以及压装后与轴承自动分离。The single machine press fitting efficiency of the end cover assembly of the wheel hub motor is low and the process is scattered.Based on analyzing the structure and press-fitting process of the end cover assembly of the wheel hub motor,a“bearing-end cover-oil seal”integrated press-fitting device was designed.In the press-fitting device,the bearing grasping mechanism used the friction between the O-ring and the bearing inner ring to grasp the bearing.A method for O-ring selection calculation and groove design using Lindley formulas and empirical formulas according to the required friction force was proposed.The prototype was trial-produced according to the simulation plan.The test results show that the designed bearing grasping mechanism can be used to realize the stable grasping and pressing of the bearing and the automatic separation from the bearing after pressing.
