Design Optimization and Analysis of Industrial Gearbox Casing to Reduce Wear of Gear and Bearings Due to Vibrations: Review

Gearbox casing is the important part of the pipe pulling machine. Vibrations are created in gear box casing while the machine is in operation causing the failure of bearing and worm gear in the gearbox. To improve the life of the bearing and worm gear it is necessary to reduce the vibrations. The vibrations are reduced by avoiding the resonance and optimization of gearbox casing. Gearbox casing is optimized by adjusting the shape and structure of housing, shape and thickness of stiffener. The aim of this study is to determine, verify and validate the vibration characteristics of the gearbox top cover using both analytical and experimental techniques. ANSYS software used to determine natural frequency response for gearbox casing. This analysis finds the natural frequency of casing. The results obtained are validated by FFT analyzer.
