本刊第七卷(1956年)第九期薛止众同志‘圆柱体齿轮螺旋角和压力角的圆棒测量法’一文,目前各厂确实需要。但关于在齿轮测量法的各节中,某些问题似尚欠妥善。今以原文为基础,试就諸问题加以补充或探讨。为便于对照计,仍采用原文代号。一、直齿轮基圆直径的测定在漸伸线齿轮中,基圆系决定轮齿曲线的基本因素。如已知某一齿轮的基圆,则只能作出一种漸伸线曲线;换句话说,即该齿轮的齿形曲线已确定。反之,如已知某一齿轮的齿形曲线,则只能有
The seventh volume (1956) ninth period Xue Zhizhong comrade ’cylinder gear helix angle and pressure angle of the round rod measurement’ article, the current plant does need. However, some problems may not seem appropriate in the sections of the gear survey. Based on the original text, try these questions to supplement or explore. For ease of reference, still using the original code. First, the determination of the diameter of the spur gear base circle In the involute gear, the base circle determines the basic elements of gear curve. If the base circle of a certain gear is known, only one involute curve can be made; in other words, the profile of the gear has been determined. Conversely, if you know the profile of a gear tooth, you can only have
