Highlights of the rotating energy supply
Moving energy made easy
For several years, igus® has been developing customer-specific systems for circular motions with energy chains, referred to as rotating energy supplies. They can be used to supply energy, data, and liquids to rotating assemblies in such applications as machine tools, robotics and bucket wheel excavators.
The igus® standard rotary modules consist of two circular guide elements. One part of the guide trough is attached to the stationary part of the system and the other to the rotating part. Because the rotary modules can be turned by both their inner or outer parts, the fixed end can be chosen freely for the e-chain®. In the main, e-chains® from the E4.1 series are used for "simple" applications and energy chains from the E2.1 and E2/000 series also used for rotary modules.
The standard for circular motion
- Rotation angles up to 540° (on one level)
- Rotation angles of 900° are possible with the igus® multi-rotation modules
- Maximum rotation angle in minimal installation space
- Rotation speed of up to 360°/s
- Lighter and more compact than static guide troughs
- Minimum displacement forces and maximum service life
- Modular construction with standardised mounting options
- Integrated strain relief and cable guidance directly in the guide trough
- Determine rotating energy supply quickly and reliably with the CAD configurator
What does "RBR" mean?
"RBR" means Reverse Bend Radius and means that the e-chain® can bend in two directions. Designs with "RBR" can be manufactured for most igus® e-chains®. The "RBR" does not have to be identical to the standard "BR" (bend radius) of the energy chain. A wide range of circular movements can be achieved with the RBR option. Rotation angles of up to 900° have been achieved.
**Tip:**Find a solution for your current design quickly and easily by submitting a request about your specific application to your igus® specialist for rotating energy supplies. We will provide you with the correct sizing, simplified 3D model and an offer with prices and delivery times.
What does "MRM" mean?
"MRM" stands for multi-rotation module and is effectively a multi-level RBR system. With a simple igus® rotation module (such as a standard RBR energy chain), a rotation angle of up to 540° can be achieved, depending on the energy chain size. Each additional module extends the angle of rotation by up to 360°. A simple stop-dog system carries the system's upper layer according to a defined angle of rotation. This technology means that only one control system is required for both layers.
Your options for igus® guide troughs
Depending on the application in question, the e-chains® glide on surfaces made of plastic, stainless steel or galvanised steel and are guided by special channels in a predefined circular movement.
