提高《机械设计基础》中轮系的识别及传动比计算教学效果的思考

The Thinking about Improving the Effect of Teaching to Identify the Type of Gear System and Calculate Transmission Ratio in the "Mechanical Design Basis"

轮系是由一系列齿轮组成的传动系统,根据齿轮系运转时齿轮的轴线位置相对于机架是否固定,将齿轮系分为定轴轮系、周转轮系。本文主要论述如何正确识别轮系类型,计算轮系传动比,正确判断轮系中主、从动轮的转向关系。

Gear system is a driving system which is composed of a series of gear, according to gear running, its axis location relative to the rack is fixed or not, to be divided into fixed axis gear system, epicyclic gear. This article focuses on how to correctly identify the type of gear system, calculate gear transmission ratio, determine the relationship of main gear and followed gear.
