• Vibration Based Condition Monitoring ofRolling Mill

     · RELATIONS BETWEEN LOAD AND VIBRATION RESPONSE (A PROPOSED THEORY): When a billet comes in contact with rolls, a tremendous pressure on the rolls occurs. The billet is under the process of plastic deformation. During this plastic deformation, a high frictional resistance is offered by a billet on a roll, which offers a load torque on a roller shaft.

  • Double Helical Gear

    It is extremely rare to use a double helical gear in an IG turbomachine because the net pinion thrust (, sum of axial impeller gas forces) would act to load one face of the helical gear more than the other. Therefore, almost all IG turbomachinery use a single helical gear.
