Cams, short for “camshafts,” are mechanical devices that play a crucial role in converting rotary motion into reciprocating motion. They are widely used in various industries and applications due to their efficiency and precision.
The history of cams dates back to ancient times when they were used as simple tools and machines. Over the centuries, cam technology evolved, leading to more intricate and specialized cam designs. Rotating cams feature an asymmetrical shape that generates different motions as the camshaft rotates. This type of cam is often found in engines and pumps.
Oscillating cams produce back-and-forth motion, making them suitable for applications like valve systems and reciprocating saws. Translating cams creates linear motion from the rotational movement of the camshaft. These cams are used in various machinery, such as printing presses.
