Rotating Actuators
Rotating Actuators
The document introduces rotating actuators as innovative devices providing torque for various applications such as clamping, twisting, and testing. These actuators are distinct from stationary models due to their revolving capability.
Specifications
Rotating actuators are available in eight standard sizes, capable of handling up to 43,150 in/lbs of torque at 1,000 PSI. They are constructed with an aluminum alloy body, featuring a precision-machined cylindrical chamber and a central splined-end shaft with fixed vanes.
Operation
Power is derived from hydraulic or pneumatic pressure applied to the vanes, which rotate the splined shaft. The movement of the vanes is limited by internal stops, but can be controlled externally by valves and stops.
Applications
1. Centrifugal and Torque Testing: Used for testing couplings and universal joints.
2. Automotive Testing: Imposes continuous and variable action on differentials.
3. Machining: Actuates chuck jaws for eccentric turning.
4. Gear Testing: Applies load or shock to gear trains.
Models and Torque Ratings
Models are categorized into small and medium sizes with two or three vanes. Torque ratings vary by model and pressure, with detailed specifications provided in tables.
Engineering Data
Standard actuators use Deublin Rotating Hyd. Deu-Plex unions, with a maximum RPM of 5,000 at 750 PSI and a maximum air pressure of 150 PSI. Lubricated air is required for pneumatic operation.
Ordering Information
Customers can specify special requirements such as shaft extensions and mounting options. The document provides a sample order format and details on various components like seals and shaft types.
Conclusion
Rotating actuators are versatile devices suitable for a wide range of industrial applications, offering customizable options to meet specific needs.

ROTATING ACTUATORS The Rotating actuator is a new innovation of reciprocating torque actuators. Its interior design and construction are similar to standard lines of stationary actuators, but the Rotating actuator, unlike the stationary models, revolves in application. Also, its applications are entirely different. It consists of an aluminum alloy body with a precision machined cylindrical chamber, a central splinedend shaft on which vanes are fixed, and barriers or shoes that provide positive internal stops for the vanes. The number of vanes and shoes within the unit limit the arc of vane travel...
