...Lucas Hildebrand; Philipp Beierer; Thomas Lohner; Karsten Stahl For the reliable operation of a gearbox, consistently sufficient lubrication of machine elements is necessary. Thus, the gearbox fluid flow plays an important role. The state of the art indicates that computational fluid dynamics (CFD...

...Bercelay Niebles Atencio; Hua-Dong Yao; Valery Chernoray This paper presents a study of the oil flow in a vertically arranged FZG gearbox. The splash and churning losses are experimentally evaluated using measurements of the resistance torque. Using high-speed imaging, the instantaneous oil...

...Dong Guo; Guobin Wen; Yawen Wang; Dongyuan Luo A prediction model of gearbox power loss based on dimensionless analysis is proposed. First, the dimensional model of gearbox power loss is established based on similarity criterion, dimensional harmony principle, and fluid mechanics π theorem...

...Manuel Oehler; Bernd Sauer; Balázs Magyar In oil-lubricated worm gears, all moving components cause power losses during operation. These losses depend, among other things, on the viscosity of the lubricant used, which in turn is determined by the temperature present in the gearbox. The dependency...

...Andrew Hamilton; Francis Quail The main driver behind developing advanced condition monitoring (CM) systems for the wind energy industry is the delivery of improved asset management regarding the operation and maintenance of the gearbox and other wind turbine components and systems. Current gearbox...
