FLIGHT CONVEYOR DRIVE Russian patent published in 2000 - IPC

FIELD: mine industry; face drives of flight conveyors. SUBSTANCE: proposed drive has two drive units, each reduction gear of each unit consists of inlet and outlet modules arranged in solid housing. Outlet modules of both drive units are identical, being made on base of double-row multiple-flow planetary train, including input shaft with central external tooth gear, fixed central internal tooth gear, planet pinions and output shaft-carrier. Input shaft of reduction gear of first drive unit is perpendicular to output shaft, and its inlet module is made cylindrically conical having first cylindrical stage with internal meshing. Input shaft of reduction gear of second drive unit is coaxial with its output shaft, and its inlet module has two-stage row train containing first cylindrical stage with internal meshing identical to first stage of inlet module of reduction gear of first drive unit, and second cylindrical stage with external meshing, whose output shaft serves as input shaft of outlet module. Inlet modules of both units have spacers in which first group of fastening holes of input unit flange is arranged concentrically relative to axis of gear of first cylindrical stage with internal meshing, and second group of fastening holes of engine flange is arranged concentrically relative to axis of gear of the same stage. EFFECT: increased power intensity and traction power of drive, manufacturability, safety margin and reliability owing to maximum unification of units and parts and component assembly of drive members. 3 cl, 3 dwg
