Patented wear control means that planetary gearboxes do not need to be adjusted or replaced

摘要

A GERMAN gear-maker has announced a planetary gearbox with an patented automatic wear control system that prevents the usual increase in torsional backlash caused by wear, thus avoiding the need to adjust or replace the gearboxes when their backlash exceeds tolerance limits. Hamelin-based Melior Motion claims that with this technology, its PSC gearboxes "virtually" ensure a backlash of less than 0.1 arc-min over their entire service lives.
