mill pinion and girth gear. In most of the instances, the above maintenance techniques have been adhered to and the failure mode can therefore not be explained. Common practice is then to turn the girth gear around on the mill and run it on the back flank. In order to maintain alignment of the girth gear and mill
How do you measure the root clearance between a girth gear and a pinion of a grinding ball mill and what is the recommended root clearance. This ball mill uses helical gears(i.e. 284 teeth girth gear with a 24 teeth pinion).
manufacture and assembly of girth gear drives increase in proportion to the size of the gear train. Distortions developing under the influence of load and temperature also increase with size. It is not uncommon to see large gears with a diameter of 14 metres. Transmission ratios typically range between 1:8 and 1:12. Under
Large girth gears are installed around the cylinder to rotate the horizontal ball mill cylinders. A pinion connects these directly to the industrial gear unit. SEW-EURODRIVE does not just provide industrial gear units, we provide the complete drive package with specially segmented girth gears.
The pinion is responsible for driving the girth gear, which in turn rotates the mill shell, grinding the raw materials into fine powder. Girth Gear and Pinion Alignment. Proper alignment of the girth gear and pinion in cement making machinery is crucial for the smooth and efficient operation of the equipment.
