High speed slip ring

High speed slip ring

AEI is a premier supplier of a precision line of high speed, low noise, durable, user friendly, liquid or air cooled slip rings. Our fleet of standard and custom slip rings are used in a variety of applications world wide for testing and development of rotating machinery.

System Description

AEI's slip rings transfer very clean and quiet signals from rotating sensors to stationary data systems. Typical applications include strain and temperature surveys of compressors and turbines, shaft torque and bending measurements, and power transfer on/off the rotor.

Installation Designs and Support

AEI welcomes the opportunity to design and fabricate the installation adapting hardware for the slip rings. This assures the customer that this hardware will be right and proven before the actual test. We typically assemble and spin test the hardware with the slip ring to assure that fit and stack-up are correct. Installation designs can include cooling cans for hot end installations, sealing arrangements for lead-wires exiting the engine shaft, and complicated outer-housing rotating installations.
 
AEI can also provide complete support for the slip ring installations. Our technicians can terminate the rotating leads, mount the slip rings, and provide test support as required to assure successful testing and data quality.

AEROSHIM

Aeroshim are preformed segments of metal foil used to secure hard or soft cylindrical sensor leads by tack welding to a surface. Standard Aeroshim covers a wide range of common lead diameters and numbers of leads placed side by side. The temperature environment and substrate material to be welded to dictates the material of shim needed, but standard Aeroshim, made of Inconel 600 alloy, is very versatile. Customers are amazed at how much time and money can be saved by taking advantage of this simple and widely used product. For requirements not met by standard Aeroshim, Aerodyn is especially capable of fabricating a custom type in a cost-effective manner.
