igus triflex TRX energy chain

igus has developed the four-dimensional triflex TRX energy chain to ensure that cables on industrial robots can be guided in motion safely, easily and compactly. The new design study replaces classic robot hose packages and retraction systems.

The chain features 40% retraction length ensured by a telescopic mechanism which allows users to save space on the third axis of their robot.

The TRX is a space-saving chain that can be fixed directly and compactly on the third axis. The energy supply twists into itself, lengthens and shortens spirally as in a telescopic pull-out. The chain utilises a screw connector system in the mechanism as well as on an integrated reset band. Cables are placed in the chain in the form of a spiral and are guided safely in the movement with the help of the chain. In addition, the cables and hoses are fastened in place in the middle of the device so that they do not leave their position when the chain is pulled.

Compared to other retraction systems, the product is said to save up to 83% weight and to require less than half the space, improving robot performance and reducing costs as additional retraction systems are not required. It can be easily connected to existing TRE series triflex R chains.
