EXPERIMENTAL STUDY ON THE TRIBOLOGICAL BEHAVIOUR OF HOMOKINETIC COUPLING

Aristia-Ioana POPOVICI

Abstract


Cycloidal pin-type gear reducers are classified within the domain of mechanical transmissions characterized by high transmission ratios, capable of transmitting torque values up to approximately 55,000 Nm. The main components of these reducers are the cycloidal gear and the homokinetic coupling, the latter of which is responsible for receiving and transmitting motion. This paper presents studies focused on the experimental determination of the friction coefficient and specific wear intensity, examining four pairs of materials and a lubricant utilized in mechanical transmissions. Based on the experimental data obtained, conclusions were drawn regarding the optimal material-lubricant combination that ensures high durability for these gears while simultaneously minimizing losses due to specific friction.
