Different fields in industrial sector need actuators for different kinds and level of actuation needs. Moreover, the devices direct a force received from other devices in a straight line to perform the fixed task.
This is the fact that such devices are counted among basic manufacturing automation equipment in industries. Let's get more information about the power sources, components, advantages and application related with different kinds of linear actuators present in the market.
Power sources
The source of power varies from kind to kind of devices. Moreover, driving power from electricity, pneumatics and hydraulics are the major power sources. Force and motion is developed through power and so the devices are manufactured by concentrating more on the power source to come up with products having standard force and motion capabilities. The conversion of different kinds of energy into mechanical energy becomes possible due to actual power sources.
Hydraulic type is built on hydraulic principle under which the alternate pressurization and depressurization makes possible achieving the linear displacement of the piston. Electro mechanical and mechanical actuators work almost with similar power source.
Major components
Belt drive, a roller screw, a ball screw and a lead screw are the components which are used to generate high speed with a shorter stroke. The lead screw is meant to convert rotary power to linear power. Belt drives are converters which come with increased speed of movement and also come with low wear and lower maintenance.
Application
The general usefulness of the devices make them ideal to get used in diverse range of areas including transportation, plant automation, medicine and packaging. It can be said that overall capabilities of the devices make them ideal for various automation applications. Device can be easily installed in plane, horizontal or vertical but sufficient space.
Lead screw or roller based motion devices are ideal for environment which is cleaner and need more speed. And hydraulic type can be used at the environment which is not that clean and there is no need for high force.
The characteristics of the actuators are weighed together with the application to determine the ideal one for specific environment. For any manufacturing operations, several actuators can be assembled as a group to achieve multiple dependent movements required.
Thus, from the discussions it can be said that it is compulsory to have proper idea about the design, size and other functionalities to get the right kind of linear actuator required in the industries.
