The Main Directions in Development of Machine Transmission Unit Diagnostics

Abstract

The state of vibration diagnostics of technical objects, peculiarities of hardware and software of manufacturers’ products, approaches and methods for diagnostics of mobile machines transmission systems are considered. The systems of mobile machines gear diagnostics in operation are analyzed and classified in detail. Special features of the tooth gears functioning, which restrict use of standard vibroacoustic tools for their diagnostics, are separated. On-board automated system aimed for the vibrodiagnostics of motor-in-wheel reducers for dump trucks BelAZ is described. The perspective directions of vibrodiagnostics development in relation to the transmission units of mobile machines are formulated.
