Research on the Optimal Design and Gear Modification of Gearbox of a Wind Turbine Based on the Virtual Prototype

Abstract:

This article describes a new mixed transmission system about the wind power gearbox. It is composed of one NGW planetary gear stage and two parallel gear stages. The modeling and optimization analysis of gearbox have been performed using Romax designer software. The load case of gear, gear modification, transmission error and Fast Fourier Transform Harmonics of wind gearbox have been carried out to investigate various performances of gearbox system. Results of the investigation show the maximum load per unit length of gear reduces about 7.2%, Transmission Error of gear reduces 74.3% and Fast Fourier Transform Harmonics decreases 77.4% after gear modification. This kind of design method has a remarkable effect on smooth running. And it provides a new research method for gear box of wind turbine.
