Rotary motion cable carriers

3. Rotary motion with RBR An RBR (reverse bending radius) is when the energy chain can travel in two directions. Each igus® energy chain can incorporate RBR designs, with the exception of certain radii for Energy Tubes R117 to R98 and for Series 07, 09, 14, 15, and 17. The RBR does not necessarily need to be identical to the normal bending radius of an energy chain. Part No. 280-15-100/425-0 describes a Series 280 energy chain cable carrier with an inner width of 5.91 inches (150 mm), standard bending radius of 3.94 inches (100 mm) and RBR of 16.73 inches (425 mm). Most rotary motions can be achieved with the RBR option. Angles of rotation up to 540° are possible. Below is an example of rotary motion using an RBR energy chain. Please consult igus® for your particular application.

Options 2. and 3. for rotary movements require less installation height. The energy chain cable carriers glide mostly on surfaces made from polymer, stainless steel or steel and are guided through channels into a rotary movement. Read about side-mounted applications for additional design tips. Bending radii, circular radii and e-chain® widths are variable with this product line.

Example of a rotary motion using RBR. Here, the outer ring rotates. The inner ring could rotate too.

Standard energy chain 350-075-200-0, angle of rotation 225°

Guide troughs

Depending on the dynamics and load of the application, the guide troughs are made from steel or stainless steel. For applications with a high cycle frequency, we suggest coating the guide troughs with polymer. igus® energy chains require no additional gliding elements for contact with the base or sidewalls. igus® offers complete systems including guide troughs, but we are pleased to offer support with drawings for your own construction.

Product range

energy chain cable carriers with RBR are available as standard for the complete triflex® range. We also offer a series of standard energy chains equipped with RBR. For all other types, RBR means a special manufacturing run, which we are more than willing to offer you as an option.

Technical data rotary motion:
max. angle of rotation = 540° (larger angles possible)
v max. = 33 ft/s
a max. = 66 ft/s²

Guide troughs for rotary applications

Rotary motion with RBR, just short of 20 ft. The inner ring rotates.
