DESIGN AND ANALYSIS OF TORSIONAL VIBRATION ON BEVEL PLANETARY GEAR

Abstract

Gears are widely used in power transmission systems for small distances. Bevel gear is used for transmitting power of intersecting or angle shaft. For the vibration Analysis, it is necessary to consider tooth contact stresses and the forces that vary in direction of rotation, which increases the fatigue effect and causes the bending of the tooth. The precise model of bevel planetary gear used in vertical rolling mill is created in AUTODESK INVENTOR in the first phase. A physical gear pairs are fabricated from the 18CrNiMo7-6. The finite element analysis is carried out in ANSYS. Final results obtained from the analysis of the proposed fabricated gear pair are compared with the theoretical analysis of bevel planetary gears.
