2. General Individual Mill Drive Concept

  • Each Roll in the mill tandem is driven individually

3. Strong Points in Choosing Individual Mill Drives

  • Increased overall power efficiency
  • Redundancy in the system in case one drive module fails
  • The right amount of torque at right roll all the time
  • Reduce:
    • Floor space, less overhead crane width required
    • No Tail Bar intermediate shafts, bearing supports, and coupling connections
    • No axial forces on the tail bar acting on the gear unit output shaft
    • The amount of spare parts, provided the drives are identical

4. Gear Unit Connection to the Mill

  • Hollow Shaft Shrink Disc with Torque Reaction Arm
  • Cylindrical Output Shaft, Rigid Flange Coupling, with Torque Reaction Arm

    • Still maintaining “Shaft Mounted” principles but with the added extra ease to release the drive from the Mill.

  • We recommend to use Bevel Planetary setup to reduce overhung load on the output shaft induced by the weight of the electro motor.
