一、问题的提出在调整机床运动链时(如滚齿机上加工螺旋齿轮时的附加运动链),常常遇到在按公式算出的挂轮比后,再求出各挂轮的齿数。当挂轮传动比精度要求不高时,可用因式分解法、对数法或其它查表法等来计算。但是在要求挂轮传动比很精确时(如要求小数点后八位数),用上述方法根本无法解决,有的文献虽亦介绍过计算方法,但均很复杂,往往产生大量的返工。作者在本文所介绍的BASIC程序求解,不仅简单方便且通用,在APPLEⅡ微机上运行时,只需几分钟即能得到满足精度要求的多种答案。现在该程序已作为我校(厂)的基本程序储存,对提高加工精度起到良好作用。
First, the problem raised When adjusting the machine kinematic chain (such as gear hobbing helical gears on the additional kinematic chain), often encountered in the formula calculated by the ratio of the rehearsal, and then find the number of each wheel gear. When the requirements of the transmission gear ratio is not high, the factorization method, logarithm method or other look-up table method can be used to calculate. However, when it is required that the gearing ratio of the hanging wheel is very accurate (such as requiring eight digits after the decimal point), the above method can not be solved at all. Although some literatures have introduced calculation methods, they are complicated and often result in a large amount of rework. The author introduced in this article to solve the BASIC program, not only simple and convenient, when running on APPLE Ⅱ microcomputer, only a few minutes you can get a variety of answers to meet the accuracy requirements. Now the program has been stored as the basic program of our school (factory), to improve the machining accuracy play a good role.
