For several years igus® has been developing customized systems for circular movements with energy chains, so-called 'rotating systems'. As a result, rotating assemblies can be supplied with energy, for example, on machine tools, robots, and bucket wheel excavators.
In order to provide solutions for such applications even more quickly to customers, the motion plastics specialist has now developed a standard range of rotary modules and offers a complete installation-friendly kit system for fast rotating applications.
"RBR" is "reverse bend radius" and it means that the e-chain® can bend in two directions. Designs with RBR can be manufactured for many igus® e-chains®. The RBR is not necessarily identical to the normal bend radius (BR) of an e-chain®. Most rotary motions can be achieved with the RBR option. Angles of rotation up to 900° have been realized. Please consult igus® for your particular application.
For rotary modules with high speeds and many motion cycles a two-tiered guide channel is used. Using the divided guide trough minimizes the relative movements of cables and the energy chain. This increases the service life of the system thanks to minimized levels of friction for the chain and cables.
In addition to our standard rotary modules, we also offer static rotary modules.
These rotary modules consist of a static guide trough. The fixed end of the e-chain® is attached to the guide trough and the moving end to the rotating part of the machine. The e-chains® from the E4-1 series are used for the rotary modules. Static rotary modules are ideally suited for easy installation in narrow spaces.
The e-chains® slide mostly on surfaces made of plastic, stainless steel or steel and are guided through baffle plates into a rotary movement.
Flexible mounting to the customer structure
Weather and UV protection are easily integrated
Open, weight-reducing structure that provides protection from coarse dirt
Symmetrical interior separation of the system and the filling
Find your assembled cable quickly and easily. Choose from among more than 3,200 assembled motor cables, servo cables, signal cables and encoder cables in accordance with 22 manufacturers' standards.
Circular movements can be implemented with several solutions from the igus® e-chains® range. The twisterchain product line offers the biggest selection for rotary movements. twisterchain solutions are particularly recommended for space restricted applications such as articulated robots, revolving tables, etc.
Cost-effective and low wear/maintenance circular motions can be implemented with the igus® twisterband in confined spaces, while reliably guiding energy, data and media.
