Abstract : A worm-wheel assembly is described wherein anti-friction balls are recirculated through helical grooves in the worm to increase the efficiency of the driving operation. This driving system is believed to have the advantages of good distribution of load forces, smooth and silent operation, very great speed reduction, high force transmission efficiency, and long service life.
