计算选配机床挂轮,即给定了传动比i后,要选择一对或两对挂轮,使其齿数除了在满足:u=a/b或u=(a/b)×(c/d)之外,还需要满足以下两个条件: (1)齿轮传动比误差小于 10-5～10-8; (2)选择满足条件要求的挂轮应是机床所配备的。 传统的挂轮选配方法是:①计算法;③查表法。但人工选择挂轮很繁琐。如:在Y3150E滚齿机上,有49种齿轮,就有21×104种组合方式可组成两对挂轮,即使人工计算出来,也只能是低精度部分挂轮,很难满足精密加工的需要。现已有用微机选配挂轮的计算机程序,但较为复杂。本文提出计算挂轮的一种新方法,并用MATLAB语言编制了相应的程序。
Calculate the optional machine pulley, that is, given the transmission ratio i, to choose a pair or two pairs of hanging wheels, the number of teeth in addition to meet: u = a / b or u = (a / b) × (c / d), but also need to meet the following two conditions: (1) the gear ratio error is less than 10-5 ~ 10-8; (2) choose to meet the requirements of the hanging wheel should be equipped with machine tools. The traditional matching method is: ① calculation method; ③ look-up table method. However, it is cumbersome to choose the hanging gear. Such as: Y3150E gear hobbing machine, there are 49 kinds of gears, there are 21 × 104 combinations can be composed of two pairs of wheel, even if calculated manually, it can only be part of the low-precision wheel, it is difficult to meet the needs of precision machining. Now available computer optional hanging gear computer program, but more complicated. This paper presents a new method of calculating the hanging wheel, and compiled the corresponding program with MATLAB language.
