METHOD FOR DIAGNOSING THE TECHNICAL CONDITION OF THE LOCOMOTIVE CREW PART Russian patent published in 2021 - IPC B61K9/00 G01N29/14 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, it can be used for monitoring and diagnosing the technical condition, assessing the residual life of bearing units, gears, motor-axial bearings and other mobile loaded components of locomotive crew part of railways. A method for diagnosing the technical condition of components of locomotive crew part, which are a bearing unit and/or a gear, consists in continuously measuring the values of acoustic emission signals during operation of the locomotive under its operational loads in real time using acoustic emission sensor (1) installed on the body of each component of the locomotive crew part being diagnosed. The measured values of the signals via communication channels (8) are transmitted to at least one intermediate analytical unit (2) installed in the locomotive. With the help of at least one intermediate analytical unit (2), the received signals are processed and sent via communication channels (9) to central analytical unit (3) located in locomotive control cabin (15), with the help of which, the resource of each diagnosed component is calculated and the crew is aware of technical condition of each diagnosed component of the locomotive crew part.

EFFECT: invention provides diagnostics and control of bearing units and gears of the locomotive crew part during its operation and without the need for stopping the locomotive and putting it on test lines and timely detection of defects in bearing units and gears of the locomotive.
