10-1 Introduction

Gears, pulleys, and chains are part of a broader category called power transmission. Power comes from a source such as an engine, motor, or windmill. The power is then transferred to a mechanism that performs some function. For example, an automobile engine transmits power from the engine to the wheels via a gear box. Bicyclists transmit the power of their legs to wheels via a chain and sprocket.

This section explains how gears, pulleys, and chains are drawn using SolidWorks and how the finished drawings can be animated. There is also a discussion of how speed is transferred and changed using ...
