As a result of the studies, the possibility of assessing the state of the working surfaces of mining machines, in particular bearing assemblies as a whole without disassembling the gearbox, is confirmed. An innovative solution in this matter is to ensure the delivery of the lubricator to tribolcoupling through the channels of the lubrication system, according to its state, determined by the size of the acoustic signal of the ultrasonic range in the friction pair.
