Converting potential energy into mechanical energy is a hot field of study in science. Actuators are the devices that scientists study that convert different forms of energy into mechanical energy or motion. Not only are actuators a hot topic of study in robotics, but they also have benefits in medicine as well. Scientists believe that the more they can improve on actuators, the more it will benefit all of mankind.
The way in which a linear actuator works is that there is a motor that rotates a drive screw using a synchronous timing belt drive. Some linear actuators can also use a worm gear drive or direct drive. Which ever the choice, the turning of the screw pushes a drive nut along the screw, which in turn pushes the rod out and rotating the screw in the opposite direction will retract the rod. According to the Association of Sciences, the drive screw is either an ACME or ball thread or is belt-driven which is what gives the machine its motion. A cover tube protects the screw nut from environmental elements and contamination thus allowing for the machines use continually without the chance of it getting gummed up. Radial thrust bearings permit the screw to rotate freely under loaded conditions and gives the linear actuator its strength.
Advanced motion control systems use actuators. Control systems are devices used to move or control objects and are found everywhere. These computer controlled systems are made possible by advancements in actuators.
There are various forms of energy that run actuators. These forms of energy include, hydraulic, pneumatic, mechanical and electrical. Linear actuators are used a lot in robotics and factory automation.
Whatever type of actuator you use, it will depend on the required motion you seek. By far and away the most popular type of actuator used is for linear or straight line motion. You also have a few options available when purchasing an actuator. You have stroke length which is the amount of linear motion you get per revolution and also the load rating which is how heavy the object that you are going to move can be. Also you should keep in mind the amount of space an actuator will require. You can also buy a programmable actuator which allows you to program various operational efficiencies of your actuators.
