Kosarev O. The reasoning for the displacement mechanism movers' parameters of the shearer for the thin seams

Object of research: process of formation of loading in frequency-regulated asynchronous electric drives of dualmoving displacement mechanism of shearer UKD300. The purpose - increase of productivity and a resource of the shearers designed for excavation of thin seams, at the expense of graunding parameters of drivers dualmoving frequency-regulated displacement mechanism. Research methods are based on use of the system approach, methods of solid-state three-dimensional modelling on the computer, planning and carrying out of experiment, methods of mathematical modelling of working process of mining machines and the statistical theory of fatigue failure of details. Novelty of work: for the first time formation in frequency-regulated drives of dualmoving displacement mechanism of shearers of incongruous between each other according to the wave phase oscillations of the load with the period, that is equal to the gear mesh period of the sprockets with the bobbin rack, and amplitude which depends on size of shift of a phase between the beginning of gearing of teeths of sprockets with the bobbin rack, average speed of moving and nominal sliding of electric motors is theoretically and experimentally established. Practical results consist in use possibility at creation and modernisation of shearers of a high technological level of the developed recommendations directed on elimination of not inphase oscillations of loading in drives dualmoving frequency-regulated displacement mechanisms of shearers. Results of work are used institute "Dongiprouglemash" by development of the new shearer UKD400 designed for excavation of thin seams. Sphere: mining machine-building.
