ABSTRACT:
Backlash or play is avoided in a mechanical, self-adjusting gear drive having two sets of gears arranged in parallel to each other by one or more torsion springs effective between a driving shaft and a driven shaft. The gear sets form a closed gear train which contains the prestressed torsion spring (12) at any suitable point. After adjustment of the prestressing, the spring or springs eliminate any backlash throughout the whole gear train.
