Abstract:
Abstract. This paper presents a review of existing theory and practice relating to main bearings for wind turbines. The main bearing performs the critical role of supporting the turbine rotor, with replacements typically requiring its complete removal. The operational conditions and loading for wind turbine main bearings deviate significantly from those of more conventional power plants and other bearings present in the wind turbine power train, i.e. those in the gearbox and generator. This work seeks to thoroughly document current main-bearing theory in order to allow for appraisal of existin

Abstract:
The fault diagnosis of wind turbines is difficult because of the wind speed changing. To solve this problem, a method designated as Hilbert space feature entropy is proposed. The information entropy based on HHT is used to describe the wind turbine bearing vibration signal under different wind speeds. Using this method to analysis the fault of the D70 type wind turbine bearings, which proved that this method can effectively identify the fault of wind turbine bearing under different wind speed . Thus the method can be used as index and basis of the fault diagnosis of wind turbine bearing.

AbstractSymmetrical spherical roller bearings (SSRB) used as main bearings for wind turbines are known for their high load carrying capacity. Nevertheless, even designed after state-of-the-art guidelines premature failures of this bearing type occur. One promising solution to overcome this problem are asymmetrical spherical roller bearings (ASRB). Using ASRB the contact angles of the two bearing rows can be adjusted individually to the load situation occurring during operation. In this study the differences between symmetrical and asymmetrical spherical roller bearings are analyzed using the f

Axial location bearings are used to carry the load imbalance between the forward thrust of an aero-engine’s compressor and the rearwards drag of the turbine that drives the compressor’s rotation. The large gas turbines manufactured by Rolls-Royce have three independently rotating compressor/turbine stages, namely the low pressure (LP), the intermediate pressure (IP) and high pressure (HP) systems. The load imbalance, or bearing load, associated with each of these systems must be assessed during an engines development phase in order to confirm the reliability of the bearings throughout the oper

Hydropower industry increasingly frequently uses water lubricated bearings in turbines. This stems from the lack of negative impact of such solution on the environment. The paper presents an analysis of the influence of shaft misalignment in a turbine with water lubricated main shaft bearing on its hydrodynamic capacity. The theoretical analysis was based on the results of calculations for experimentally verified elastohydrodynamic lubrication (EHL) model. The obtained results showed impact of the stiffness of bush material and the degree of misalignment on bearing's hydrodynamic capacity.

Abstract:
Condition monitoring of gear-based mechanical systems in non-stationary operation conditions is in general very challenging. This issue is particularly important for wind energy technology because most of the modern wind turbines are geared and gearbox damages account for at least the 20% of their unavailability time. In this work, a new method for the diagnosis of drive-train bearings damages is proposed: the general idea is that vibrations are measured at the tower instead of at the gearbox. This implies that measurements can be performed without impacting the wind turbine operation. The tes

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz. However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system.
