摘要

摘要: 为了改善弧齿锥齿轮印痕的稳定性,提出了印痕敏感性系数的优化设计方法.首先,参数化齿面印痕,并分析等效错位量对印痕参数的影响;定义了印痕参数相对于错位量的敏感性系数,建立基于印痕面积和印痕水平位置的敏感性系数之和最小的数学模型,优化小轮机床调整参数,获得具有稳定印痕的齿面.算例的仿真结果表明:在一定的错位量范围内,优化后齿面印痕的敏感性系数之和减小了,改善了印痕的敏感性;印痕发展试验验证了齿面印痕在实际工况下的稳定性.

Abstract: In order to improve the stability of contact patterns of spiral bevel gears,the optimization design method of the sensitivity coefficient of contact patterns was proposed.Firstly,the contact patterns were parameterized,and the effect of equivalent misalignments on the parameter of the contact patterns were investigated.The sensitivity coefficients of the parameter of contact patterns to the misalignments was defined,and the objective function established by the minimum sum of the sensitivity coefficients and the machine-tool settings of pinion were adopted as optimization variables to construct an optimization model for the stability of contact patterns.The simulated results of the numerical example show that the sensitivity of contact patterns to misalignments can be improved by implementing the above methodologies in proper ranges.The contact pattern development tests also validated the stability of the contact patterns under the operating conditions.
