Helicopter Slip Rings & Rotary Joints

Helicopters

EVERAXIS has long, proven field experience in designing slip rings and rotary joints for helicopters. The lightweight, compact design, reliability and resistance to vibrating environments of EVERAXIS rotating equipment has been appreciated by customers around the globe for decades. EVERAXIS is part of the latest generation programs in Europe, the US and Asia.

EVERAXIS supplies slip rings for a wide range of helicopters and aeronautical applications. Helicopter Slip Rings include slip rings for the de-icing of rotary wings but also instrumentation equipment for data transmission.

EVERAXIS also designs custom Rotary Joints for airborne surveillance optronic sensors, and for search and rescue radars in helicopters.
Withstanding intense vibrations and shocks at high temperatures during extended periods of time while securing data and/or power transmissions and maintaining a low weight for airborne equipment are requirements that EVERAXIS engineering teams meet and exceed.

EVERAXIS can support any customer early in the design process to further optimize the performance and cost of use of their rotating systems.

Capsule Slip Rings

Power_capsule_slip_rings

Power Capsule Slip Rings

Power Capsule Slip Rings are required wherever high voltage - several kV - or high current - several kA - are transferred between stationary and the rotating platforms. They integrate rotor, stator, bearings and casings.

Slip Rings Separates

HD Video Slip Ring Separates

HD Video Slip Ring Separates are designed for applications that have limited space and that require large amounts of data to be transmitted. OEMs can integrate these stator and rotor separates in cases where a capsule slip ring would not fit into the system.

Dense_Signal_Slip_Rings_Separate

Dense Signal Design Slip Ring Separates

Many applications that have very tight packaging constraints lead to a dense or low pitch. Compressing many signals into a small package requires specialized manufacturing techniques. EVERAXIS has provided dense signal count platters and drums to many aerospace and defence customers over several decades.

High Speed Slip Rings

Embedded_High_Speed_Slip_Ring

Embedded High Speed Slip Ring

Embedded High Speed Slip Rings can deliver high power and generate low noise for ultimate data transfers at speeds of up to 20,000 rpm.

RF Rotary joints

Waveguide_Rotary_Joint

Waveguide Rotary Joint

Waveguide Rotary Joints are used for the rotary transmission of power and signal between the stationary and rotating parts of a radar or satcom system. EVERAXIS has designed and produced single and multi channel Waveguide (WG) Rotary Joints since 1958. Every new design is simulated in FEM software as well as physically tested for optimal performance. Each high power Waveguide Rotary Joint is tested at maximum peak power before shipment.

Coaxial_Rotary_Joint

Coaxial Rotary Joint

EVERAXIS single and multi channel Rotary Joints are designed to work in rotating 50 Ohm systems, where uninterrupted and low loss signal transfer is required. Coaxial Rotary Joints are compact and lightweight compared to Waveguide Rotary Joints.

Through Bore Slip Rings

Low_temp_application_Through_Bore_Slip_Ring

Low Temp Application Through Bore Slip Ring

Through Bore Slip Rings are typically used in harsh environments such as high altitudes, which involve extreme cold temperatures. EVERAXIS has many designs suitable for high altitudes without performance loss.

Contactless Slip Rings

Above_1_Gb_s_Ethernet_Contactless_Slip_Ring

Above 1 Gb/s Ethernet Contactless Slip Ring

Thanks to its extensive expertise, EVERAXIS is able to develop high speed Contactless Slip Rings allowing above 1 Gb/s data transmission and continuous operation

Twist Capsules

HD-SDI_Twist_Capsules

HD-SDI Twist Capsules

HD-SDI Twist Capsules allow for high data rate transmission across a limited rotating mechanical joint in typically military and aerospace systems.

Integrated Rotating Systems

Gimbal_Integrated_rotating_system

Gimbal Integrated rotating system

EVERAXIS manufactures slip rings and integrates other elements to provide superior assembly for our customers. These assemblies are used on sensor and gimbals for military programs in land, air and sea applications.
