Theoretical and experimental modelling of the tribological behaviour aspects of contact elements in the precessional gearing (PG)

BOSTAN, Ion; STOICEV, Petru; POȘTARU, Gheorghe; VACULENCO, Maxim; BUGA, Alexandru; KULEV, Mihail; POȘTARU, Andrei; PLATON, Andrei (Technical University of Moldova, 2022)

This paper deals with the theoretical-experimental model of the tribological behavior of the contact elements in precessional gears (PG) in the functions of conjugate profiles of linear velocities "convex-concave" or ...
Theoretical contributions on the selection of possible tribological couples of materials for the manufacture of precessional transmissions

BOSTAN, Ion; STOICEV, Petru; BUGA, Alexandru; POSTARU, Gheorghe; TRIFAN, Nicolae; PLATON, Andrei (Technical University of Moldova, 2022)

Selecting gear materials is a great challenge for engineers. Gear teeth are subject to difficult and severe loading conditions. Simultaneous action of alternating normal and tangential dynamic stresses occurs, contact ...
