论文部分内容阅读
本刊1957年第8期上刊登有颜龙先生所著的“机床变速箱中齿轮计算的讨论”一文,文中的基本论点乃是:对於齿面硬度H_B≤350的钢质齿轮均可不必进行轮齿的抗弯计算,同时作者还在文中推荐了一个校验齿面硬度H_B>350时是否需要进行抗弯计算的简化近似公式。我们认为文中的某些基本论点是不正确的,其所推荐的公式较之现有的方法也并未有所改进与简化,反而增添了缺点。现将我们的意见提出来与颜龙先生讨论,并就正於读者。
The magazine published in 1957 on the 8th published by Mr. Yan Long, “Machine Tool Gearbox in the discussion of gear” article, the basic thesis is: for the gear hardness H_B ≤ 350 may not have steel gear In addition, the author also recommends a simplified approximate formula for calculating the bending resistance when the flank hardness H_B> 350. We think some of the basic arguments in the article are not correct. The proposed formulas have not been improved or simplified compared to the existing ones, but they have added shortcomings. Now put forward our comments to discuss with Mr. Yan Long, and just as readers.
