GLIGHT CONVEYOR DRIVE Russian patent published in 2001 - IPC

FIELD: mining industry; flight conveyor face drives. SUBSTANCE: proposed drive of flight conveyor has input and base output modules, each arranged in its housing. Output module is made on base of multiple-row multiflow planetary gear train. It has floating central shaft-gear with external teeth, fixed multirim central wheel with internal teeth, rows of planet pinions in number equal to number of rims of multirim central wheel, and output shaft-carrier. Housing of base input module has two identical input connecting flanges, axis of first flange being coaxial, and axis of second flange being perpendicular to central shaft-gear. Central shaft-gear in bade input module is enclosed by first intermediate hollow shaft coupled by toothed universal joint with central shaft-gear and mechanically coupled with second intermediate hollow shaft through bevel pair with gear ratio equal to 1. Second intermediate hollow shaft is coaxial to second input connecting flange. Input modules is made in form of planetary stage consisting of input shaft with mall central tooth wheel, planet pinions, fixed carrier and output large central internal tooth wheel provided with seat and lock for connecting with seat place of first or second hollow shaft. Housing of input module is provided with connecting output flange identical to input connecting flanges of base output module. EFFECT: improved operation reliability, simplified servicing and possibility of repair by unit repair method. 2 cl, 3 dwg
