CHAPTER 8 GEARED SYSTEMS AND VARIABLE-SPEED MECHANISMS GEARS AND GEARING Gear tooth terminology Gears are versatile mechanical components capable of performing many different kinds of power transmission or motion control. Examples of these are • • • • Changing rotational speed. Changing rotational direction. Changing the angular orientation of rotational motion. Multiplication or division of torque or magnitude of rotation. • Converting rotational to linear motion and its reverse. • Offsetting or changing the location of rotating motion. Gear Tooth Geometry: This is determined primarily by pitch, depth, and pressure angle. dedendum: The radial distance between the pitch circle and the dedendum circle. depth: A...
