Classification of Defects in Mobile Machine Transmissions

The classification of defects in gears of mobile machines is considered. It is noted that the main processes that contribute to the occurrence of defects and malfunctions in gears are: friction that occurs in the zone of direct contact of the teeth, gradual destruction of the surfaces of parts during their relative movement, the presence of alternating loads, periodically occurring dynamic shocks in the transmission, excess stress, acting on the contact areas, yield strength, repeated transmission overloads caused by complex loading conditions. A detailed analysis of the causes of defects in the transmissions of mechanical and hydromechanical transmissions of mobile machines was carried out. The classification of damage and defects in gears makes it possible to study deviations in the operation of these gears and make timely decisions to increase the service life of gears, and also serves as a database for creating algorithms for on-board diagnostic systems for recognizing faults in gearboxes of mobile machines for various purposes.
