Representation Methods of Typical parts(典型零件的表达方法)

Parts have various shapes. Following their manufacturing features,they can be roughly divided into shafts and sleeves, plate wheels, fork levers,brackets, and boxes. In the following chapters, we provide a representation of those parts.

在生产中零件的形状是千变万化的,但就其结构特点来分析,大致可以分为轴套类、盘轮类、叉杆类、支架类、箱体类等。下面结合典型例子介绍这几类零件的表达方法。
