Pinion Shaft an overview | ScienceDirect Topics
Tumbling mills are most commonly rotated by a pinion meshing with a girth ring bolted to one end of the machine (Figure ).The pinion shaft is either coupled directly or via a clutch to the output shaft of a slowspeed synchronous motor, or to the output shaft of a motordriven helical or double helical gear reducer. In some mills, electrical thyristors and/or DC motors are used to give
