Gear Drive Basics
Gears are mechanical devices, designed with teeth specifically shaped to minimize wear, vibration, and noise, while also maximizing a power transmission’s efficiency. They are able to reverse the direction of rotation, change the speed of rotation, and transfer rotation to a different axis. This course will describe the purpose, types, performance, and applications of gears.
