The centre drive device of the tube mill drives from the end surface. Large gearboxes are needed in the lower rated power range without girth gear drive. Because of their large power capacity, NGC’s power shunting gearboxes are especially effective in this application. The auxiliary drive device is installed at the rear side of the main motor or arranged between the main motor and the main gearbox.
Stage: 2 or 3, power shunting type gear pair with parallel axes
Driving speed ratio: maximum i=80
Rated power: P=800 kW ~8,000 kW
Optimized meshing accuracy of gears, lower noise, and high efficiency;
The housing is analyzed and optimized by FEM, with less deformation during operation process, and more stable operation;
Secured manufacturing quality and higher reliability;
Compact design with high power/weight ratio;
Simple to operate, and good usability and maintenance.
Crushing ore, coal sheets or cement clinker in industries of building materials, coal, and mines.
