摘　　要：单一通过调整主轴导向套长度和空心主轴位置,往往难以达到理想间隙控制效果。对此,提出基于失效概率的新能源电机轴瓦间隙自动控制技术。该技术通过对新能源电机运行机理的深入分析,合理设计轴瓦配合间隙,并基于配合间隙区间优化机组轴线的位置,分析稳定状态,并通过极限状态函数和强度失效阈值,自动控制轴瓦间隙。测试结果显示,采用该技术调整轴瓦间隙后,摩擦力显著降低,具备较为理想的间隙控制效果。适用于新能源电机应用需求,提升运行效率。Simply adjusting the length of the spindle guide sleeve and the position of the hollow spindle often fails to achieve the desired clearance control effect.In response,a new energy motor bearing clearance automatic control technology based on failure probability was proposed.This technology conducts in-depth analysis of the operating mechanism of new energy motors,reasonably designed the clearance between the bearing shells,optimized the position of the unit axis based on the clearance interval,analyzed the stable state,and automatically controled the clearance between the bearing shells through the limit state function and strength failure threshold.The test results show that after adjusting the clearance between the bearing shells using this technology,the friction force is significantly reduced,and it has a relatively ideal clearance control effect.It’s suitable for the application needs of new energy motors and improving operational efficiency.
