棉纺常见的转速、线速度、产量等工艺计算在现行教材中虽然给出了定义和公式,但各种设备传动、构造的千差万别往往让学生摸不着头绪,尽快让学生摸到规律掌握计算方法是保证教学的关键,就从传动路径、传动比等机械传动的原理入手阐述解决这一难题的规律与技巧。 Cotton spinning common speed, line speed, output and other process calculations in the current teaching materials although the definition and formula given, but a variety of equipment transmission, the construction of different and often make students feel scratching as soon as possible so that students get to the law to grasp the calculation method is To ensure the teaching of the key, from the transmission path, transmission ratio and other principles of mechanical transmission set out to solve the law and skills to solve this problem.
