    摘要:

    齿轮强度标准在行业中贯标率较低,使得基于不同标准得到的齿轮产品设计结果缺乏通用性.以应用较广的ISO 10300-2014和ANSI/AGMA 2003-B97标准为对象,研究弧齿锥齿轮接触与弯曲强度计算标准的差别,探讨两种标准中各设计量与修正系数的定义方法、取值及对轮齿强度的影响.设计多组算例比较两种标准下齿形与工作参数对接触和弯曲强度的作用,并通过有限元接触分析对其进行验证.结果表明,由于参数的定义和取值不同,两种标准计算的接触与弯曲强度差别较大.有限元接触分析与两种标准的计算值比较显示,综合考虑材料的疲劳强度极限与齿轮结构强度,结合接触和弯曲强度的安全系数来评估弧齿锥齿轮的承载能力更为合理.

    Abstract:

    Lower implement ratio of gear strength standard still occurs in the industrial applications, which results in lack of generality for the design of gear products based on different standards.Comparative analysis of contact and bending strength using ISO 10300-2014 and ANSI/AGMA 2003-B97 standards for spiral bevel gears is carried out, which is verified by finite element contact analysis in this paper. The differences for the definition and evaluation methods of the design parameters and the correction factors between the above two standards are investigated. The effects of geometrical and working parameters of a spiral bevel gear pair on contact and bending strength are illustrated subsequently and discussed briefly. The results show that the maximum contact and bending stresses calculated by the two gear standards are largely deviated, which are closely relative to the definition and evaluation methods of the design parameters and correction factors. Furthermore, the comparative results of finite element contact analysis and the calculation results from the gear standards indicate that the fatigue strength limit of gear material and the gear strength are necessary to be included simultaneously. These results also show that a more reasonable determination of load capacity in spiral bevel gears is attained according to the safety factors of contact and bending strength.
