摘要
针对合套挤压后整体式自润滑关节轴承存在的无载启动力矩过大的问题,以GE15DE1TK/HVS0型自润滑关节轴承为研究对象,采用有限元数值模拟技术对其力矩调整过程进行模拟分析,确定了滚轧工艺的参数范围,并估算了最终成形状态的无载启动力矩值。以模拟得到的滚轧力为依据,对该型轴承进行样件加工及工艺验证,通过标准力矩测量方法得到样品件的无载启动力矩,并将检测结果与模拟结果进行对比,以判断数值模拟方法的可靠性。对比结果表明,数值模拟结果与工艺试验结果之间的误差较小,所建立的有限元数值模型可以对整体式自润滑关节轴承滚轧工艺参数及无载启动力矩进行有效预测。
Aiming at the problem of excessive starting torque without loading of the integral self-lubricating spherical plain bearing after the sleeve extrusion,GE15 DE1 TK/HVS0 self-lubricating spherical plain bearing was taken as the research object,the simulation analysis of the torque adjustment process was carried out by the finite element numerical simulation technique,the parameter range of the rolling process was determined,and the starting torque without loading in the final forming state was estimated. On the basis of the simulated rolling force,the samples fabrication and the process verification of the spherical plain bearing were carried out. The starting torque without loading of the sample was obtained by the standard torque measurement method,and the measured results were compared with the simulation results to verity the reliability of the numerical simulation method. The comparison results show that the error between the numerical simulation results and the process test results is small. The established finite element numerical model can effectively predict the rolling process parameters and the starting torque without loading of the integral self-lubricating spherical plain bearings.
