Improvement of the system of maintenance and repair of mining machines according to the actual state

The risk assessment of mining machine failure is the most important step in the implementation and modernization of a good service system. A fresh and innovative approach is required in relation to the selection of an optimal and modern maintenance strategy, acting as an anti-degradation factor. Within the framework of such a fresh and combined strategy, such maintenance and repair systems as RCM (Reliability-Centered Maintenance) and RСM II (RiskBased Maintenance) have successfully proven themselves. A technique has been developed to improve the efficiency of transmissions of mining machines by improving the operating mode of lubrication of the working surfaces of resource-determining interfaces. The article describes a technique for assessing the residual life of a large-module open gear transmission of a mining machine. It has been experimentally confirmed that the hardness of the surface layer of the metal of parts that are in conjunction changes depending on the time of operation, that is, the hardness of the surface layer can be used as a parameter for monitoring the degree of wear and residual life of parts. The possibility of increasing the efficiency and wear resistance of resource-determining interfaces of transmissions of mining machines by the formation of artificial environments for their functioning and renovation of the lubricant is substantiated on the basis of an assessment of the change in the value of the acoustic signal of the ultrasonic range in a friction pair generated by resource-determining interfaces.

Keywords: mining machine, preventive maintenance, maintenance strategy, transmission, residual life, lubricant, ultrasonic acoustic signal, lubricant renovation.
