HYDRAULIC ROTARY ACTUATORS – E3
Hydraulic Rotary Actuators – E3
The Eckart E3 is a hydraulic rotary actuator that has been especially designed for mobile applications; however, it is not limited to such applications. This rotary actuator functions according to the “helical gear” principle and, due to its compact design, only requires a minimum amount of space.
The Eckart E3 is identical in form to the products of its competitors, but has unique selling points which can offer considerable advantages: firstly, there is virtually no backlash; secondly, there is no play in the 4-point roller bearing; and thirdly, no compact seals which can be subjected to stress on both sides are used. Consequently, there is no more wobbling, such as on the work platform, when a lateral movement is made.
Helical Spline Hydraulic Rotary Actuators:
Our rotary actuators are the helical spline design. This means, a piston and a helix, or sliding spline, work together to convert the linear motion of the piston into rotational motion. Composed of two moving parts and some form of housing, the sliding helical splined gear concept within the actuator is used in many applications where a rotary movement is required. Helical Spline Actuators function when the piston is axially displaced using hydraulic pressure causing simultaneous rotation of the piston. Standard amounts of rotation are 90°, 180°, and 360°; but are available generally up to 720° or more. Additional rotation is created by making the spline gears longer while maintaining the same diameter. The primary benefit to this type product compared to alternative designs such as linkages using hydraulic cylinders (linear actuators) is its compact design.
