This paper outlines the comparison of efficiencies for worm gearboxes with a center distance ranging from 28 to 150 mm that have single reduction from 5 to 100:1. Efficiencies are calculated using several standards (AGMA, ISO, DIN, BS) or by methods defined in other bibliographic references.
It also deals with the measurement of torque and temperature on a test rig, required for the calibration of an analytical model to predict worm gearbox efficiency and temperature.
There are also examples of experimental activity (wear and friction measurements on a block-on-ring tribometer and the measurements of dynamic viscosity) regarding the effort of improving the efficiency for worm gear drivers by adding nanoparticles of fullerene shape to standard PEG lubricant.
