Embodiment Construction

[0014] The embodiments described herein can be used with a bucket-type yaw system, where the bending moment and / or torque are laterally supported, and the weight of the housing is supported by flat or tapered bearings or slip rings ( For example, open needle slew bearing (open needle slew bearing) support. This bearing structure does not require high-precision machining and / or manufacturing of the yaw brake and / or bearing. In addition, the embodiments described herein include at least one sliding pad that is in contact with the base of the outer cover and includes a low-friction material. This sliding pad supports the outer cover laterally while allowing the outer cover to rotate relative to the tower.

[0015] figure 1 This is a vertical projection view of an exemplary wind turbine 10 from the side. In this exemplary embodiment, wind turbine 10 is a near horizontal axis wind turbine. In another embodiment, the wind turbine 10 may have an upwardly inclined angle (not shown) va...

Abstract

The invention relates to a Wind turbine and method of assembling the same. A nacelle assembly (100,200,300) is provided. The nacelle assembly (100,200,300) includes a base (110), a support flange (138) extending from a tower (12), and a yaw bearing (102) coupled between the base and the support flange, the yaw bearing including a plurality of horizontally oriented rollers (118) configured to support the base thereon.

Description

Technical field [0001] The embodiments described herein generally relate to a nacelle assembly for a wind turbine, and more specifically, to a yaw bearing within the nacelle assembly. Background technique [0002] At least some known wind turbines include a yaw bearing between the nacelle and the wind turbine tower. The yaw bearing allows the outer cover to rotate relative to the wind direction. More specifically, the yaw bearing usually includes a transmission, and the yaw drive motor rotates the housing by engaging the transmission of the yaw bearing. [0003] At least some known yaw bearings are slewing bearings that include concentric races. Between the concentric races, the slewing bearing may include balls, vertically oriented rollers, and / or sliding surfaces. The transmission device may be located on the inner surface of the inner race or the outer surface of the outer race. Either the inner race is connected to the outer cover and the outer race is connected to the towe...
