The function of a rotary actuator is to convert hydraulic energy into rotary mechanical energy.
ROTARY ACTUATORS ROTARY ACTUATORS (OR HYDRAULIC MOTORS) • The function of a rotary actuator is to convert hydraulic energy into rotary mechanical energy. • Rotary actuators are the hydraulic equivalents of electric motors. Hence_rotary actuators are also called as hydraulic motors. • The hydraulic motors are very much identical in construction and size to rotary type pumps. They work on exactly the reverse principle to that of rotary pumps. • Instead of pushing the fluid as pumps do, in a hydraulic motor the rotating elements (ie., vanes, gears, pistons, etc.) are pushed by the pressurized fluid. This enables the hydraulic motor to develop the necessary output torque and rotating motion. • The hydraulic motors are usually rated/specified in terms of the torque developing capacity or differential pressure. The hydraulic motors can be classified based on their degree of angular movement as : 1. Continuous rotary hydraulic motors, and (i) Gear motors, (ii) Vane motors, and (iii) Piston motors. 2. Limited-rotation hydraulic motors* (i) Vane type, and (ii) Piston type. Now we shall discuss the construction and operation of gear, vane, and piston motors, in the following sections.1. What are Rotary Actuators?
2. Classification of Hydraulic Motors
