The R&P system is based on a pinion with a 1" pitch circle. The total linear distance traveled per revolution of the pinion is thus 3.14159". With the 3:1 reduction, this means that the distance traveled per motor revolution is 3.14159 / 3, or 1.0472".
The gearless mill drive eliminates ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto ... stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD ...
The Quadrex Mill Drive was created in partnership with CMD and Ferry Capitain Engineering as a large mill drive solution for the mining industry. Internal torque splitting capability of the Quadrex Mill Drive transmits motor input power to the pinion shaft and evenly divides among two mill pinions.

Large concrete surface at mill drive end, Fig. 2A, with increased tendency towards cracking.
The teeth of the pinion gear mesh with the teeth of the girth gear, creating a strong and reliable connection that transfers torque from the motor to the mill. Types of Mill Pinion Gears. Mill pinion gears come in several variations, each designed for specific applications. The most common types include spur, helical, and double helical pinion ...
These rack and pinion motors are available as compact servo or geared options and can be mounted to any motor with the appropriate tolerance motor adapter. By combining them with our planetary or helical bevel gear units and STOBER servo motors, you get the benefit of extremely compact, highly dynamic drive solutions.
For gearless drives, motor torque output at the maximum desired operating mill speed and ball charge volume has to be determined. Primary Mills: Torque Output (by Motor) vs Torque Demand (by Mill) For the purposes of this discussion, "drive speed" refers to the output speed of any mill drive system, whereas that of a GMD refers to actual ...
