【 摘 要 】

An experiment was conducted to confirm the reliability of the evaluation of the technical condition of transmission elements during operation in terms of the magnitude and nature of the acoustic emission signal, while completing the negative effect of the artificial environment on the durability of the transmission elements. Thus, the results of the experiment are presented where the acoustic emission signal in the friction pair was changed depending on the pressure value in the contacting pair and the angular velocity value. The possibility of obtaining an estimate of the technical state of the transmission elements during its operation in terms of acoustic and emission characteristics has been experimentally confirmed.
