Design of Rotor Balancing System for Industrial Purpose
(Pulchowk Campus, 2022-03) Adhikari, Sabin
Most of the modern machines have the rotating parts containing bearings and gears. The mass distribution on either side of the rotary mass should be even. The unequal mass distribution leads to unbalanced forces causing vibrations and the noise. Hence, there is escalating demand of the reliable, safe, precise and versatile rotor balancing system. This research study focused on the design of the rotor balancing system with the balance quality grade G2.5 to G40. The structural and modal analysis of system component is being carried out according to Finite Element Method (FEM) in Ansys and Solidworks software after CAD model design in Solidworks. The different positions of rotor in the shaft were studied, and the rotor at the center was found to deform less and with less chances of undergoing resonance. The machine components were analyzed and found to sustain the equivalent stress and deformation. The unbalance system was studied by considering two cases one with lumped mass and other with mass removed. The permissible unbalanced is also calculated for the different rpm and rotor weight. The target balancing of this study is for the disc type rotor of 3000 rpm as per ISO-1940-1 standard.
