  • Double Helical Gear

    Tumbling mills are most commonly rotated by a pinion meshing with a girth ring bolted to one end of the machine (Figure 7.10). The pinion shaft is either coupled directly or via a clutch to the output shaft of a slow-speed synchronous motor or to the output shaft of a motor-driven helical or double helical gear reducer. In some mills
