摘要

摘要: 应用间接耦合法对三维轮齿进行热-结构耦合分析，获取轮齿在齿宽方向上的热弹耦合变形量分布，将齿宽方向变形量数据点拟合成关于齿宽位置的函数，在Walker齿廓修形基础上，提出一种新的轮齿修形方式，结果表明：在轮齿齿宽方向上，热变形分布不均匀，使得热弹耦合变形呈中间小两侧大的分布趋势，新的修形方式可适应轮齿不同齿宽处的变形量，弥补了Walker齿廓修形因齿宽方向修形量恒定所引起的齿宽局部修形过大或不足的缺陷，使轮齿修形更为精确。

Abstract: Gear thermo-elastic coupling analysis was carried out with finite element indirect coupling method, and the thermo-elastic deformation distribution along tooth width direction was obtained. The function fitting of thermo-elastic deformation data points along tooth width direction was carried out with MATLAB. Based on gear profile modification, a new style of gear modification was presented. The elastic deformation showed uneven distribution, and thermo-elastic deformation in middle region was less than the gear end-faces along tooth width direction. The new style of gear modification met different deformations along tooth width direction, and the problem that the modification amount was larger or less in local for the Walker gear profile modification was avoided. The new style of gear modification design was more accurate.
