作者简单地介绍了美国AGMA1958年公布的齿轮承载能力设计计算方法,认为是几十年来美国齿轮设计方法的进步,方法精神,有可取之处。 主要优点是:(1)新方法结合世界最新的齿轮理论和美国齿轮制造商的实际经验,统计资料和生产技术;(2)充分利用了指数法,便于工程应用;(3)在材料热处理,加工方法和检验方面的技术进展,有助于设计方法的进步。 但新方法还未能将齿轮设计的困难问题,完全介决(1)沿齿宽的载荷分布及二对以上齿的分担载荷问题(2)对应力集中及残余应力的影响,未能在公式中准确反映(3)材料许用应力的取定,有时不易。
The author briefly introduced the United States AGMA 1958 announced the proposed method of calculating the holding capacity of the calculation, that the decades of US gear design methods of progress, the spirit of the method, there are merits. The main advantages are: (1) The new method combines the latest gear theory in the world and the actual experience, statistics and production technology of American gear manufacturers; (2) making full use of index method to facilitate engineering application; (3) Technological advances in processing methods and inspection contribute to the advancement of design methods. However, the new method has failed to completely solve the problem of gear design. (1) The load distribution along the tooth width and the load sharing problem of two or more teeth. (2) The influence of stress concentration and residual stress can not be solved in the formula In the accurate reflection (3) allowable material allowable stress, and sometimes not easy.
