IGUS TRAPEZOIDAL THREAD ACHIEVES 82 PER CENT EFFICIENCY

Trapezoidal threads have been mechanical engineering classics for decades. Motion plastics specialists rely on optimised interaction between the metal lead screw and the plastic lead screw nut geometries.

At igus, the nut's thread flanks are larger than those of classic trapezoidal threads, as is the width of the lead screw. This is a small а change, but it has significant consequences: enlarging the thread flank results in more high-performance plastic used for power transmission. This means more tribologically optimised material, i.e., regarding friction and wear. “The asymmetry has enabled us to extend the service life so that it is about 30 per cent longer than that of symmetrical trapezoidal threads," said Thorben Hendricks, Head of the dry spin Lead Screw Drive
