9 New Twister- Chain E-Chain System TwisterChain New Series Selecting the correct TwisterChain New If you would like us to design your TwisterChain application, simply supply us with your requirements. Please use the igus system design form at the end of this chapter. If you would like to specify the E-Chain and the guide trough yourself, please work through the following points and enter the results on the calculation sheet at the end of the chapter. 1. Determine the series and E-Chain width - Example of client data: l Available construction space outer radius mm l Inner radius = 311 mm l α otation angle = 220 l Installation height = 466 mm l ø cable of client = 22 mm l Minimum bend radius of client cable = 165mm Estimate the dimensions of the E-Chain by means of the internal separation with filling and select the series, or verify the maximum cable diameter and select the series using the next larger permissible ø. (For the inner height, we recommend the consideration of a cable clearance of approximately 20% of the chain s inner height and width. Maximum ø cable TwisterChain : TC32 = 25 mm, TC42 = 39 mm, TC56 = 53 mm Example: Maximum ø cable of client 22 mm Series TC32 (next larger) 2. Specify the outer radius A Select the next smaller X2 of the E-Chain from the available installation space of the outer radius. From the dimension X2 please subtract 80 mm, which results in the necessary outer radius A. Selection of the chain outer radii, see table; dimension X2 of the corresponding series Formula: A = X2-80 mm Example: 1. Available construction space outer radius 592 mm 580 mm (X2) 2. X2 580 mm - 80 mm A 500 mm (next smaller selected) 3. Specify the inner radius I Add the allowance of 25 mm to the available installation space of the inner radius and select the next larger X1 of the E-Chain. The maximum width Bi results from the selected value. Selection from the table of the corresponding series. Formula: Imin = X mm Example: Available installation space inner radius 311 mm + 25 mm = 336 mm X1 350 mm = Bi 11 (108 mm) 4. Specify the bending radius Basically, the chain s bending radius is determined by the largest bending radius of the cables. Selection from the table of the corresponding series. Example: 1. ø 22 mm (7.5 x ø) 22 mm x 7.5 = 165 mm cable s bending radius minimum mm (next higher selected) esults Part No. TC / Specify the required installation height H An allowance of 170 mm is added to twice the value of the selected chain s bending radius. Example: 175 mm x mm = H 520 mm 6. Calculate the required number of links Formula: n = π x A x α + K 360 x T T Please note: The resulting number of links must always be rounded up! The mounting brackets may be attached only to the outside plates of the TwisterChain. Consequently, the number of links must always be rounded up to the next highest odd number! 8.91 Note: In the case of machine elements which both move to the left and to the right following a circular path, the rotation angle can be determined by adding to two angles. A = Outer radius T = Pitch α = otation angle I = Inner radius HF = Height incl. 50 mm clearance a = Acceleration = Bending radius H = Nominal clearance height n = Number of links X1 = Inner machine construction space K = Add-on for bending radius FZmax = Maximum additional load X2 = Outer radius A, incl. clearance hi = Inner height ha = Outer height

32 E-Chain System TwisterChain Series Selecting the correct TwisterChain If you would like us to design your TwisterChain application, simply supply us with your requirements. Please use the igus system design form at the end of this chapter. If you would like to specify the chain and the guide trough yourself, please work through the following points and enter the results on the calculation sheet at the end of the chapter. 1. Determine the series and chain width Specify which cables you would like to use for the chain. The type of cable(s) and the largest cable diameter determine the series and chain width selection. We recommend that you allow for a cable clearance of approx 20% of the chain s inner height and width. For instance, you must choose Series 3808 for a cable diameter of 1.18 (30 mm). 2. Specify the outer and inner radius Determine the construction space available to you (dimensions X1 and X2) Example: α = 220 /max. cable diameter.94 (24 mm) Series 2808 X2 = (580 mm) A = (500 mm) X1 = (310 mm) Imin = (390 mm) selection table (392 mm) 3. Specify the bending radius H-ha HF = (460 mm) H (410 mm) = = 7.00 (178 mm) 175* *(next smallest radius) 2 esult: Series 2808, Part No / Calculate the required number of links Number of links: = π x A x α x T K T The resulting number of links must always be rounded up! The mounting brackets may be attached only to the outside plates of the TwisterChain. Consequently, the number of links must always be rounded up to the next highest odd number! ecommendations for design without additional components Legend a = Acceleration α = Angle of rotation A = Outer E-Chain radius Ba = Outer E-Chain width Bi = Inner width FZmax = Max. additional load H = Nominal clearance height ha = Outer E-Chain height hi = Inner E-Chain height HF = equired clearance height incl (50 mm) clearance I = Inner radius K = Series-dependent add-on for bending radius n = Number of links = E-Chain Bending radius T = Pitch v = Speed X1 = Inner machine construction space X2 = Outer radius, incl. clearance LK = Distance pivot point/ outer mounting holes The following clearances are absolutely essential for proper design function: I min = X (80 mm) X 2 min = A (80 mm) H F = H (50 mm) Chain height including clearance FZmax.

45 E-Chain System TwisterChain Series Guide Trough - Type 02 igus E-Chain System Telephone Fax Internet: sales@igus.com QuickSpec/FQ: The delivery of an igus TwisterChain includes the guide trough, which affords certain advantages: l Guidance of the chain l Minimized wear on the chain l Optimal running smoothness l otational angle up to 400 The modular design of the guide trough makes it possible to connect a large number of chain, circle and bending radii by using the same trough sections. If the chain radius changes, the trough can simply be adapted without purchasing a completely new trough. The table below will assist you in selecting the right guide trough system. The specified part number includes the complete trough system. In all cases, you should state the TwisterChain series when ordering.

The rotation angle is dependent upon support for the upper run and should be assembled on-site. If on-site assembly is not possible. we will deliver a supporting structure which can be assembled on the floor and is based on the height of the lower trough run. If necessary, we will design a supporting structure specially adapted to your installation!
