Problem. Despite the vigorous development of electric vehicles, task facilitating driver to handle with elements mechanical transmission remains relevant. For this purpose, automation units is performed. instance, so-called robotic gearboxes are widespread. The principle operation such similar ones, but special separate actuators carry out selection and shifting into desired gear. design a gear...

Gearboxes are mechanical transmission systems that consist of multiple gear wheels and shafts. The transmission ratios of the gears are determined by the size and interconnection of these components. Gearboxes have to adhere to very strict requirements regarding weight, production costs, and available space. Moreover, the load cases as a result of motor-vehiclepairings are often not clear a pri...

Speed increase transmission gear box is the primary vibration and noise source of wind turbine, Operational modal method was adopted to collect impact data and response data of each point based on the gearbox test model. ANSYS finite element model is established to simulate the wind turbine gearbox. Then the modal frequencies of the two methods were compared to ensure the test model is correct....

This paper presents a novel solution method based on measurement and analysis of current signals for gearbox fault recognition of wind turbine. A gearbox with typical oil-leakage fault is purposely made. The oil-leakage gearbox and a normal gearbox are used as experimental models to measure and analyze the current signals of generator. This work employs wavelet transform (WT), empirical mode de...

It is well known that a faulty gearbox vibration signal exhibits an amplitude modulation (AM) as well as a phase modulation (PM). These modulation carry out a lot of useful information about health condition. This paper presents two approaches for modeling amplitude and phase modulation in gearbox vibration signal. These last are used to describe the vibration signal by a state space model. The...

the winD inDustry has experienceD a rapid expansion. As wind farms are aging, their operations and maintenance issues are gaining in significance. The wind industry has been affected by failures of wind turbine components such as main bearings, gearboxes, and generators. Replacement of failed components results in the high cost in energy production. Therefore, research in fault identification a...
