METHODS FOR ASSESSING THE TECHNICAL STATE OF THE RESOURCE AND MECHANICAL TRANSMISSIONS HEADING-SHEARER "URAL-20R"
The methods of technical diagnostics and residual life assessment of parts and components of mechanical transmissions mining machines. The results of experimental studies carried out by experts PSTU portable software and recording complex «VATUR» to assess the magnitude and nature of the load drives the executive bodies of the miner «Ural-20R». Proved promising and versatile approach to the determination of the energy of the residual resource, as individual components and complex multistage mechanical transmissions of mining machinery. Substantiated the main provisions of the methodology for assessing the technical condition of mechanical transmissions heading-shearers to change the current and motor power excavation machinery. Based on the analysis of regime parameters, development of statistics and design features heading- shearer «Ural-20R» proved the concept of onboard automated diagnostic complex, providing increase operational efficiency and combines the rational organization of repair work at enterprises engaged in production of potash ore by underground methods. The proposed method and apparatus allow the reduction of energy consumption to determine the fracture process potash array, which is a consequence of gas-dynamic phenomena and carry identification outburst zones.
