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 …

This paper proposes a review-based comparative study addressing the critical issue of tidal
stream turbine drivetrain options. Indeed, tidal stream turbines are still in development …

This paper presents detailed descriptions, modeling parameters and technical data of a
5MW high‐speed gearbox developed for the National Renewable Energy Laboratory …

Non‐torque loads induced by the wind turbine rotor overhang weight and aerodynamic
forces can greatly affect drivetrain loads and responses. If not addressed properly, these …

This study compares the impact of drivetrain configuration on the mass and capital cost of a
series of wind turbines ranging from 1.5 MW to 5.0 MW power ratings for both land‐based …

Рассмотрены вопросы создания мультипликаторов для ветрогенераторов средней
мощности. Предложена принципиальная кинематическая схема мультипликаторного …

This study presents a structural analysis and optimization for the lightweight design of a
buoyant rotor-type permanent magnet (BRPM) generator, which was first presented in Bang …

The replacement of double-row spherical roller bearings with double-row tapered roller
bearings as the main shaft support in wind turbines has been proposed as one of the …

Traditionally, the drivetrain (DT) of a wind turbine (WT) is defined as the rotating, mechanical
linkage, transmitting torque between the wind rotor as an entire subsystem, which includes …

For the past decades wind turbine technology has significantly evolved and wind energy
became a mainstream energy resource. However, further optimization and cost reduction of …
