Mechanical Actuating Systems topics include: Motion types, freedom degree, kinematic chains, cams, gear trains, ratchet, pawl, belt drives, chain drives, bearings and preloading. Mechanical actuating systems can convert mechanical motion into linear motion or vice versa. They can also translate rotary motion into a different speed.  Here are some types of mechanical actuators: Hydraulic actuators: Use hydraulic power, such as a fluid or cylinder motor, to facilitate mechanical operation. Hydraulic actuators can exert a large force because liquids are almost impossible to... Show more
