The effects of carrier pinhole position errors and non-torque loads on the load sharing of planet gears in a conventional-type three-point suspension wind turbine gearbox were investigated. A 1/4 scale-down model of a 2-MW class wind turbine gearbox was used, and a parametric study was conducted using a three-dimensional analysis model capable of performing system-level analysis. Axial force, radial...
The most important design factors in the life of a pitch reducer for a wind turbine are the load distribution on the contact surface of the gear teeth and load sharing among the planet gears. The effects of the output shaft bearing of the pitch reducer of a wind turbine on the load distribution and load sharing were analyzed in this study. Using commercial software, four pitch reducer models with...
Slurry containing SiC powder and oil is used to cut ingots with a wire in a solar cell wafering process. The slurry, which is generally recycled due to its high price, produces a residue known as sludge during the recycling process. The sludge is mainly composed of SiC, Si, and oil. This study proposed a method to remove Si and oil from sludge to obtain a high-purity SiC powder of approximately 98...
