Abstract
This paper presents some theoretical and experimental results regarding the influence of the friction coefficient upon the energy losses in spur gears and worm gears. Tests have been made on medium carbon steel cylindrical specimens for the first case and FcA2 antifriction cast iron - OLC 45 steel and CuSn12T bronze - OLC 45 steel for the second case. They had a pure rolling relative motion and then rolling with sliding motion having different specific sliding degrees. The experimental results showed new aspects of the variation mode of the frictional coefficient in different conditions. This, in its turn, influences the energetic performances of gears.
Keywords: gears, worm gears, friction coefficient, energy losses
