The upper run glides on the glide bars from the middle of the travel (image with the high-speed glide bar) For long travels, the upper run of the igus ® e-chains ® rests on the lower run. The upper run of the chain glides partly on the lower run and partly on a glide bar. The diagram below shows this. For lateral guidance, an igus ® guide trough is necessary. If the fixed end of the systemcan be placed in the centre, the e-chain ® length is calculated as follows: . Placing the fixed end in the centre of the travel o ff ers the shortest e-chain ® length. The length of the e-chain ® then corresponds to slightly more than half of the travel length. Depending on the technical data for the selected e-chain ® , the mounting height of the moving end of the e-chain ® must be lowered on some applications. In these cases please contact igus ® and we'd be glad to advise. Selection criteria Following parameters are required for design of a trough system: ● e-chain ® type (Series, width Bi , radius R ) ● Travel and travel speed ● Fill weight ● Acceleration ● Lateral acceleration ● Environmental conditions Design and installation of the guide trough The height of the trough must be at least twice that of the e-chain ® height: . The sides must provide a chamfered opening. The trough inner width is the same as the e-chain ® outer width, plus 4mm for an aluminium SuperTrough and plus 5mm for a steel guide trough . Along the side of the trough, where the upper run cannot glide on the lower run, glide bars must be installed. Guide troughs with and without glide bars can be obtained from stock for almost all igus ® e-chains ® . When assembling the trough parts, the following pointsmust be given particular attention: ● Properly align all trough parts upon installation ● All screw heads should be flush with the trough ● Smooth level transition between the end of the e-chain ® and the glide bars ● Solid connection with the glide surface. These pointsmust be observed when using assembly-friendly igus ® guide troughs. e-chain ® length Trough inner height Innerwidth,AluminiumSuperTroughs Inner width, Steel guide trough Guide trough with glide bar Guide trough without glide bar Total length of guide trough 3DCAD, configurators, service life calculation andmore www.igus.eu/guide Outer e-chain ® width Inner e-chain ® width Bend radius O ff set fixed end Travel Half length of travel Trough inner width Trough outer width Trough inner height Trough outer height e-chain ® outer height e-chain ® length Installation height (with lowered moving end) Over length for long travels gliding Add-on (with lowered moving end) Required clearance height Trough set Installation set glide bar C-profile
