ZX, FZX Planetary Centre Drive Gearbox

Description

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. NGC's multiform planetary gearbox is more effective in this application because of its large power capacity. The auxiliary drive device is installed at the rear side of the main motor or arranged between the main motor and the main gearbox.

 

Technical Data

Specification: 23
Stage: 2 or 3, 1st. gear pair with parallel axes (configuring according to specific requirements) + 2nd.planetary gear pair + 3rd. planetary gear pair
Driving speed ratio: maximum i=125
Rated power: P=1,250 kW ~10,000 kW

 

Advantages

Optimized meshing accuracy of gears, lower noise, and high efficiency;
Gearbox and planetary frame are analyzed and optimized by FEM, ensuring deformation during operational processes is reduced and more stabilized;
The drive structure of multiform planetary gearboxes is nationally patented;
Secured manufacturing quality and higher reliability;
Compact design with the best power/weight ratio;
Because of smaller spatial arrangement of the device as a whole, less space is needed.

 

Applicable Fields

Crushing ore, coal sheets or cement clinker in industries of building materials, coal, and mines.
