摘　　要：本文在弧齿锥齿轮的轮齿接触分析 (TCA)和承载接触分析 (LTCA)的基础上 ,根据计算所得的齿面接触点附近的准确几何形状 ,一定载荷下的齿间载荷分配和齿面载荷分布状态 ,采用弹性力学中两个空间曲面弹性接触的计算公式 ,提出了航空弧齿锥齿轮齿面接触应力变化过程的计算方法 ,进一步结合齿轮的加工参数设计和齿面修正 。On the basis of Tooth Contact Analysis (TCA) and Loaded Tooth Contact Analysis (LTCA),an approach to calculating the maximal tooth contact stress course in the whole meshing period of spiral bevel gears has been provided,by using the theory of elasticity.The effects of tooth surface geometry,load share,tooth deformation and manufacturing errors on contact stress course could be shown by means of the approach.An optimal method for high tooth contact strength was presented,in which by controlling the shape and amplitude of the transmission error curve,that is the curvature on tooth height,the maximal contact stress could be reduced and an improved contact strength could be obtained.
