摘要
轨道交通产品轴承拆卸方法和拆卸装置的研究,对于轨道交通产品制造尤其是产品检修的效率、质量提升具有重要意义.本文针对国内某型地铁车轴轴承的拆卸难题,通过对现有拆卸方法的研究和分析,设计了一种可自适应调节角度的拆卸装置.同时,通过构建三维模型开展关键结构部件的有限元分析,对拆卸装置的刚度和强度进行验证,并完成应用实例验证.应用结果表明,该拆卸装置能够有效提升工作效率,保证了该型地铁轴承拆卸的完整性,有效避免了拉伤轴承及车轴.
Abstract
The research on the bearing dismounting method and device for rail transit cars is very important to the efficiency and quality of rail transit product manufacturing and maintenance.Aiming at the bearing dismounting problem of a certain domestic rail transit car,this paper designs a self-adaptive dismounting device based on the analysis of the existing bearing dismounting methods.Finite element analysis of the key structural components is carried out by constructing a three-dimen-sional model,and the stiffness and strength of the device are verified through application.The application results show that the dismounting device can effectively improve the working efficiency,ensure the integrity of the bearing,and effectively a-void the strain of the bearing and the axle.
