论文部分内容阅读
本刊1959年第5期发表了奚鸿祥同志的“用附加分度法铣削直齿錐齿轮”一文(下称原文),文中详述了这种方法有关调整方面的计算公式与算例。读后觉得该法简单易行,目前在一般中、小型工厂及修配厂中,用于修配工作以及低速、低精度直齿伞齿轮的单件与小批生产,还是比较适当的,因而具有一定的实际意义。这里,把一些不成熟的看法提出来与该文作者商榷,并供大家讨论,请给予指正。一、对基本出发点的商榷原文所介绍的加工原理见图1(即原文图2):先切出齿间直槽,然后把齿轮绕分度头中心线
The fifth issue in 1959 published in Comrade Xi Hongxiang “with an additional indexing method of milling straight bevel gear,” a text (hereinafter referred to as the original), the article details the adjustment method of calculation formulas and examples. After reading that the law is simple and easy, at present, in general, small factories and repair shop, for repair work and low speed, low precision straight bevel gear single piece and small batch production, or more appropriate, and therefore have a certain The practical significance. Here, some immature ideas put forward to discuss with the author and for your discussion, please correct me. First, the basic starting point of the discussion The original description of the processing principle shown in Figure 1 (the original figure 2): first cut out the straight groove between the teeth, and then the gear around the centreline center line
