A fault diagnosis method based on wavelet and adaptive interference canceling is presented for the identification of a damaged gear tooth. A damaged tooth of a certain gear chain generates impulsive signals that could be informative to fault detections. Many publications are available not only for the impulsive vibration signal analysis but the application of signal processing techniques to the...

The paper primarily employs the 3D calculation method of helical gear-meshing line and meshing position, in addition to traditional stiffness calculation. This analysis correction load-sharing are beneficial for improving assembly process high-powered critical equipment. dynamic models rigid–flexible coupling, velocity–torque, force planetary gear trains nuclear power plants established based o...

This article considers the Wolfrom planetary gear train, its most used variants and areas of application. It is emphasized that train a compound one, not simple one (single-carrier). demonstrated how kinematic power (efficiency) analysis under consideration may be performed using lever analogy torque method based on it. Equations for efficiency determination useful in optimization procedures ha...

Power-split hybrid vehicles use planetary gears as power transmission and ratio devices, which are compact, efficient, and provide continuously variable gear ratio using a simple, low-cost and reliable structure. Many prominent hybrid vehicles currently on the market or under development are power-split hybrids. To take advantage of this type of hybrid power-train, it is beneficial to fully exp...
