Vertical Mill Gearbox
Vertical mill gearboxes require extremely high rated power and availability. Gearboxes, as one of the key components of vertical mills, are used for transmitting power, reducing the rotating speed of the motor to the one required by the mill during operation, and supporting the mill’s grinding table. Higher axial force and partial radial force generated during the grinding process are transmitted to the mill foundation through thrust bearing and its housing.
Modular design, good component interchangeability.
Longer bearing life, more reasonable lubrication distribution.
flank modification to improve the overall bearing capacity and noise reduction performance.
Finite element analysis to improve gearbox operation stability.
Innovated complete thrust bearing device.
