齒輪是机器上重要部件之一,几乎每台机器沒有齒輪就不能工作。因此当测繪人員測繪机器时,或是枫修車間檢修机器、为机器制造配件时,就要精确地測算出原有齒輪的有关数据。在齿轮测算中,压力角的测算是比較困难的,特别是現在很多机器都广泛地应用着变位齒輪,因此对齒輪压力角的测算就更为复雜。“机械制造”过去介绍过一些这方面的理論和方法,伹所介紹的方法中也还存在着不够简便和不够精确的缺点,有必要加以研究补充。现把个人的补充意見寫在下面,请大家批評指正。“机械制造”’七卷十二期的“快速测齒卡尺的研究报告”中介紹测算齿輪压力角的方法是:用不同压力角的卡
Gear is one of the most important parts of a machine, and almost every machine can not work without gear. Therefore, when surveying and mapping personnel mapping machine, or repair shop Fengfeng repair machines, machine parts, it is necessary to accurately calculate the original gear of the relevant data. In the gear calculation, the pressure angle calculation is more difficult, especially now that many machines are widely used in variable gear, so the pressure angle of the gear is more complicated. Mechanical Manufacturing introduced some theories and methods in this field in the past. However, there are still some shortcomings in the methods introduced, which are not easy enough and not precise enough. It is necessary to study and supplement them. Now the personal comments added below, please criticize correction. The “Method for Measuring Rapid Caliper” in “Machine Building”, Volume 7, Issue 12, describes how to calculate the pressure angle of a gear by using a card with different pressure angles
