Linearantrieb, insbesondere für Anschlußköpfe von Laserbearbeitungsanlagen

摘要

A linear drive mechanism includes a cable wound on a motor-driven cable drum for accurately displacing a driven member in a linear direction relative to a housing, the driven member being adapted to carry the connecting head of a laser processing system, or the like. The ends of the cable are connected with the driven member and with the housing, respectively, the cable being tensioned to frictionally retain the cable turns on the cable drum, and to effect accurate positioning of the driven member with a low wear rate and without play or backlash.
