摘要
外部条件对圆弧齿线圆柱的齿轮的齿面接触区产生一定影响.本文通过理论分析及试验研究,具体分析了轴线平行度误差及齿轮承载大小等因素对齿面接触区的影响,得出了点接触型圆弧齿线圆柱齿轮对以上影响因素具有不敏感性的重要结论,从而证明了该种齿轮对外部条件具有广泛适应性的独特优点.同时,本文还从改善齿面接触情况出发,提出关于选择凸凹齿面刀盘半径的若干考虑.
The working condition of circular-arc-tooth-trace (CATT) cylinder gear has certain effect on the contact zone between its tooth flanks. Based on the theoretical and experimental analyses, the paper discusses the effects of the parallel error of the axes and the load on the tooth flanks of CATT gear, and come to the conclusion that the point-contact CATT gear is not sensitive to the working condition such that it has wide adaptability. In addition, the paper put forward a proposal concerning how to select the cutter head radius for machining the convex and concave tooth flanks fo CATT gear in order to improve their contact condition.
