近年来,国内外一些专业刊物曾介绍过用电子计算器及可编程序计算器选择机床配换齿轮(配轮)的方法,其原理可分为以下两类:1、把一个给定的传动比i化成多个渐近分数,取其中某一个最佳分数作为配轮传动比的近似值,再根据这个分数求配轮的齿数组合。2、把传动比在计算器上累加,当得到一个与整数非常接近的和时,就把此和数圆整之后作为分子,累加次数作为分母,构成一个近似分数,根据此分数进行因式分解,求出配轮。 In recent years, some professional journals at home and abroad have introduced the method of selecting gears (with wheels) with electronic calculators and programmable calculators. The principle can be divided into the following two categories: 1, a given transmission Than i into a number of asymptotic scores, whichever is the best score as an approximation with the gear ratio, and then according to this score with the number of teeth with the wheel combination. 2. Add the gear ratio to the calculator. When you get a sum that is very close to the integer, take the sum as a numerator and accumulate the times as the denominator to form an approximate fraction, and then factorize according to the fraction , Find the match wheel.
