SCRAPER CONVEYOR DRIVE Russian patent published in 1998 - IPC

FIELD: mining industry; scraper conveyors for mine faces. SUBSTANCE: drive has two drive units arranged longitudinally and crosswise relative to conveyor axis. Each drive unit consists of input and output modules installed in separate solid housings. Output modules of two drive units are identical and made on base of two row multiple flow planetary gear train. Input module of first drive unit is made cylindrically bevel with first cylindrical stage with internal gear meshing. Second module of second drive unit is made on base of planetary gear train in which gear rim of fixed central wheel with internal meshing is installed on flexible suspension made in form of studs with flexible bushings passing through holes of rim and secured in module housing uniformly over wheel circumference. EFFECT: improved manufacturability of drive, increased strength and reliability, power-to-weight ratio and traction power owing to maximum unification of parts and units and by-unit assembly of drive members. 4 cl, 4 dwg
