The invention relates to the equipment for driving of mine workings at underground development of minerals. A mine development machine has a carrier that is frame on which at right and left sides the right and the left caterpillar trolleys are fixed, and on supports of frame axles of pins of actuator reducer with rotor actuating device are installed, with loading buckets, berm cutters, cutter drums, collection screens, conveyor, separating screen, on the frame hydro-cylinders of lift of reducer of actuating device are fixed as well, rods of those are fixed on its body, at the rotary parts are installed in bearings equipped with forced lubrication system, this includes pump, pressure pipeline, collectors and system of distribution pipes on bearings of shafts of toothed bearings of reducer. According to the invention frame of propulsion section has two hermetically closed cavities, and pressure pipeline between the pump and the collector is arranged as coils placed in those cavities, at that both cavities of frame are filled with cooling liquid for cooling lubrication liquid in lubrication system. Increase of durability of bearings of shafts of toothed gearings of combine reducer is achieved, decrease of temperature of environment. |
