1.概述我们知道,在齿轮传动中,由于线接触齿面对加工、装配误差及变形等过于敏感,实际应用的共轭齿面常常要将理论的线接触齿面作一定的啮合失配(mismatch),使它们成为点接触的。早在五十年代,苏联H.N.诺维科夫在研究大承载能力的齿轮传动时,就论述了点啮合传动的瞬时接触条件和齿面相对曲率的关系等问题,三十年来,在这个领域内取得了长 1. Overview We know that in the gear drive, the linear contact tooth surface is often too sensitive to the mismatch between the theoretical line contact tooth surface due to the fact that the line contact tooth surface is too sensitive to machining, assembly errors and deformation. mismatch), making them point contact. As early as the fifties, Soviet Union HN Novikov in the study of large load-carrying gear drive, discusses the point of engagement transmission instantaneous contact conditions and the relative curvature of the tooth surface and other issues, three decades, in this area Made long
