Mechanical energy is an advanced science and the study of how linear actuators convert various energy forms into mechanical energy to produce motion is thoroughly explored. There are various uses of linear actuators in the field of science including the medical field. Scientists are of the opinion that the more these simple machines are studied, the more they will be able to assist mankind.
A motor rotating a drive screw with the aid of a synchronized timing belt drive makes a linear actuator work. Some of them can even use a direct or worm gear drive. Either way, it is the turning of the screw that helps in pushing the rod out and rotation in the opposite direction that retracts the rod. As per the Association of Sciences, the machine gets its motion from the drive screw which can be belt driven, ACME or ball thread. The screw nut is protected from environmental elements or contamination by a covering tube that therefore allows the machine to be used continuously without it gumming up. The linear actuator gets in strength during heavy loaded condition from a radial thrust bearing that allows the drive screw to rotate freely.
Most motion control systems use linear actuators and the modern ones are run using computers. The movement or control of objects is through a control system that uses these linear actuators. The movement is possible due to the use of a linear actuator.
Actuators are run by different energy forms. The energy forms used are hydraulic, mechanical, pneumatic and electrical. You will find a linear actuator used extensively in factory automation as well as robotics.
What is linear motion?
Any object moving in a straight line is said to have linear motion. This is the basic behind a linear actuator. You need to research and decide which kind of linear actuator would be best suited for your project. There are some points that you must consider when choosing one including the speed, load rating and stroke length of the linear actuator. If you will be using the actuator for a specialized job then you need to factor in its programmability as well. a linear actuator is helpful in just about any job. When looking to choose the right one for a project, make sure you have covered all aspects – find out whether the linear actuator requires any specific safety mechanisms or if there will be space issues or if you are required to address any environmental issues.
