A linear actuator is an actuator that creates linear motion (i.e., in a straight line), in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers , and in many other places where linear ...
By means of a leadscrew, rotary motion can be adapted to function as a linear actuator (which produces a linear motion, but is not a linear motor). Another broad classification of actuators separates them into two types: incremental-drive actuators and continuous-drive actuators. Stepper motors are one type of incremental-drive actuators.
Planetary roller screws are used as the actuating mechanism in many electromechanical linear actuators. Due to its complexity, the roller screw is a relatively expensive actuator (as much as an order of magnitude more expensive than ball screws), but may be suitable for high-precision, high-speed, heavy-load, long-life, and heavy-use applications
Rigid chain actuators were developed from “chain rammers” that used a single “ram chain” thrust from a magazine to load heavy-caliber ordnance into the breech of a cannon. Robert Matthews received a US patent for his “Mechanical Rammer” in 1901 which used a roller on the leading end of the chain to guide it and allow thrust without ...
Snow blowers can generally be divided into two classes: single-stage and two-stage. On a single-stage snow blower, the auger (the paddle mechanism visible from the front) pulls snow into the machine and directs it out of a discharge chute. The auger contacts the ground, making single-stage snow blowers unsuitable for use on unpaved surfaces.
A linear actuator opens and closes valves that can be operated via linear force, the type sometimes called a "rising stem" valve. These types of valves include globe valves, rising stem ball valves, control valves and gate valves. [2] The two main types of linear actuators are diaphragm and piston.
