Gearbox Fault Diagnosis Using Bispectrum Analysis
Gearbox is widely used as a common part for power transmission and quite essential in the mechanical devices. However, due to the complicated structure, bad working conditions and other reasons, gears and bearings are easily to be damaged or out of order. Especially when failures occurred in machine system, the system usually presents stronger nonlinearity [...]

Structural and Thermal Analysis of 1.5MW Gearbox in Wind Turbine
Gearbox is the most important component of mechanical transmission in wind turbine, which performance directly determines the wind turbine efficiency. And life expectancy is usually required of 20 years. Because of its poor working conditions, gearbox is damaged very easily with complicated and varied windload. Body of gearbox as an important component of itself, its [...]
Research on the Press-mounting Process of Gearbox Assembly
The gearbox assembly processes include many press-mounting processes such as gearbox inner spindle parts and the sleeve parts. The proper selection of the press-mounting process affects the performance of the gearbox directly. The appropriate Gearbox press-mounting process need press-mounting machine with the function of monitoring press-mounting force-displacement accurately. To achieve this function, this paper will [...]
