Definitions

  • the present subject matter relates generally to wind turbines, and more particularly to systems and methods for securing an outer race of a bearing to bedplate of a wind turbine.
  • Windpower is considered one of the cleanest, most environmentally friendly energy sources presently available, and wind turbines have gained increased attention in this regard.
  • a modern wind turbine typically includes a tower, a generator, a gearbox, a nacelle, and one or more rotor blades.
  • the nacelle includes a rotor assembly coupled to the gearbox and to the generator.
  • the rotor assembly and the gearbox are mounted on a bedplate member support frame located within the nacelle. More specifically, in many wind turbines, the gearbox is mounted to the bedplate member via one or more torque supports or arms.
  • the one or more rotor blades capture kinetic energy of wind using known airfoil principles.
  • the rotor blades transmit the kinetic energy in the form of rotational energy so as to turn a shaft coupling the rotor blades to a gearbox, or ifa gearbox is not used, directly to the generator.
  • the generator then converts the mechanical energy to electrical energy that may be deployed to a utility grid.
  • the majority of commercially available wind turbines utilize multi-stage geared drivetrains to connect the turbine blades to electrical generators.
  • the wind turns the rotor blades, which spin a low speed shaft, i.e. the main shaft.
  • the main shaft is coupled to an input shaft of the gearbox, which has a higher speed output shaft connected to the generator.
  • the geared drivetrain aims to increase the velocity of the mechanical motion.
  • the gearbox and the generator are typically supported by one or more bearings and mounted to the bedplate via one or more torque arms or supports.
  • Such bearings typically include an inner race, an outer race, and a plurality of roller elements arranged therebetween.
  • the outer race is typically stationary, whereas the inner race can rotates to provide rotation of the main shaft. Accordingly, the outer race needs to be firmly clamped axially within the bedplate. As such, the bearings are typically held in place via a cover that is mounted to the bedplate.

  • the first bearing is held in place via a first cover that is secured to a first mounting surface of the bedplate.
  • the first bearing includes an inner race, an outer race, and a plurality of roller elements arranged therebetween.
  • the second bearing is held in place via a second cover that is secured to a second mounting surface of the bedplate.
  • the second bearing also includes an inner race, an outer race, and a plurality of roller elements arranged therebetween.
  • the first and second bearings engage the main shaft so as to provide rotation thereof.
  • the drivetrain assembly also includes at least one flexible member arranged between the outer race of the second bearing and the second cover. As such, when the flexible member (s) is compressed, a gap between the second mounting surface of the bedplate and the cover is closed or reduced. It should be understood that the drivetrain assembly may further include any of the additional features as described herein.
  • the present disclosure is directed to a method for securing an outer race of a bearing within a bedplate of a wind turbine.
  • the method includes removing a portion of a first cover flange of a cover of the bearing to create a space between the first cover flange and an outer race of the bearing.

Abstract

Selon la présente invention, un ensemble arbre principal d'une éolienne (10) comprend un arbre principal (34) fixé à une plaque de base (48) de l'éolienne (10) et un palier (54, 58) logé à l'intérieur de la plaque de base (48). Le palier (54, 58) est maintenu en place par l'intermédiaire d'un couvercle (68) qui est fixé à une surface de montage (49) de la plaque de base. De plus, le palier (54, 58) comprend une bague de roulement intérieure (56, 64), une bague de roulement extérieure (55, 62), et une pluralité d'éléments de rouleau (57, 66) agencés entre celles-ci. De plus, le palier (54, 58) vient en prise avec l'arbre principal (34) de façon à assurer sa rotation. L'ensemble arbre principal comprend en outre un élément flexible (72) disposé entre la bague de roulement extérieure du palier (54, 58) et le couvercle (68). Ainsi, lorsque l'élément flexible est comprimé, un espace entre la surface de montage de la plaque de base (48) et le couvercle (68) est réduit ou fermé.
