Abstract


Noise and vibrations are the main reasons for failure of transmission system, minimizing the noise and vibration in power system is a constant development, gear faults are the main sources that create vibrations in mechanical systems.

According to our experience, to apply at the cement plant of Hamma Bouziane in Industrial Zone  of Constantine and using very sophisticated measuring means (OMNITREND processing software) and the development of the vibration sensors, an anomaly was detected in the part ( pinion / crown).

The objective of this research is to determine the influence of the defect size on the mechanical behavior of helical gear under dynamic load and the different mode shape of vibration of pinion-crown. The distribution of contact stresses, bending stresses was investigated using FEM and the obtained stresses are then compared with AGMA standard. The modeling of gears was performed using SOLID WORKS software and imported into the finite element code ANSYS.
