摘　　要：对数螺旋锥齿轮接触问题属于高度非线性的复杂接触问题,在传动过程中为保证齿轮能够安全、可靠地工作,要对该齿轮进行接触强度分析,使得齿轮的最大接触应力不得超过理论允许的限度。在已有的对数螺旋锥齿轮模型的基础上进行动、静态对比接触分析,找出主、从动轮齿面接触应力的最大值并与理论值相比较,结果表明,齿面最大应力值均在应力允许范围内,满足强度要求。The contact problem of logarithmic spiral bevel gear is deemed as a highly-nonlinear contact problem.In order to ensure the safe and reliable working of gear in transmission process,it is necessary to analyze the contract strength of gear to make the maximum contact stress of the gear within the theoretical allowable limit.On the basis of the existing logarithmic spiral bevel gear model,the dynamic and static contact analysis was carried out to find the maximum value of contact stress between the driving wheel and driven wheel.The maximum value is compared with the theoretical value.The comparative results show that the maximum stress value of the gear face is within the allowable range of stress,and meets the requirement of strength.
