Get MoreRoller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.
Get MoreConventional utility-scale wind turbines often use three- stage gearboxes. The first stage is often a planetary drive because that design handles high torque best. The later two stages use helical gears. To give an idea of the torque coming from a rotor, consider a 1.5-MW turbine working at its rated output. 1.5 MW = 2,011 hp.
