Energy chain for light robotic applications
30 October 2016
With the introduction of the triflex TRLF.125, igus has extended its TRLF family which now includes a 125mm nominal diameter e-chain, in addition to existing 65, 87.5 and 100mm internal diameter sizes.
These TRLF energy chains are suitable for robotics and other applications that require electrical power cables, data cables and hoses to remain secure and protected during multi-axis movement. With this new 125mm size, even stiff or large hoses, or indeed large numbers of individual cables, can be inserted quickly and easily, reducing labour costs and assembly time.
The mechanical design of TRLF has three internal chambers to separate power, data and hoses and ensure reliable guidance while avoiding damage during torsional movement. The design provides a defined bend radius and a maximum torsion of approximately ±200° per metre of chain.
To add or remove cables or hoses, each link can be opened manually or by screwdriver to facilitate rapid filling, modification or maintenance. As the TRLF system does not use any internal steel cables or spring elements, additional links can be easily added or removed via a simple ball and socket joint. igumid G material is used in the TRLF chain to provide strength, while remaining lightweight.
