Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 2 As shown, the invention includes nacelle 15 , yaw ring gear 19 , brakes, yaw drive 18 and tower 20 . A plurality of yaw drives 18 are arranged on the bottom plate of the nacelle 15, and the nacelle 15 and the yaw drives 18 are fixedly connected by bolts. The bottom of the nacelle 15 is equipped with a lower bracket 19 by bolts, and the lower bracket 19 is arranged corresponding to the yaw drive 18. The bottom plate of the nacelle 15 and the lower bracket 19 are provided with a through hole for the yaw drive 18 to pass through. The holes are stepped holes. The yaw drive 18 is provided with an upper flange 182 and a lower flange 183, the upper flange 182 is fixedly connected with the nacelle 15 by bolts, and the lower flange 183 is placed on the step surface of the through hole of the lower bracket 19 superior. In this way, the yaw drive 18 a...

Abstract

The invention discloses a yaw structure of a winding generating set. The yaw structure comprises a cabin, a tower drum, a yaw drive, a plurality of brakes and a yaw gear ring, wherein the yaw gear ring is fixedly connected to the tower drum; the position, close to the outer circle of the yaw gear ring, of the bottom of the cabin is equipped with multiple brakes; friction plates are separately arranged between the top surface, the bottom surface and the side surfaces of the yaw gear ring and the upper side surfaces, the lower side surfaces and the bottom surfaces of brake grooves; and force moment regulating devices are arranged between the friction plate on the bottom surface of the yaw gear ring and the brakes. The yaw structure is simple in structure, is low in cost, is convenient in maintenance, and avoids the problem that cabin blocking slot processing is inconvenient, and avoids the risk that the cabin is damaged during cabin blocking slot processing.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a yaw structure of a wind power generating set. Background technique [0002] The yaw device of the wind turbine is an important part of the wind turbine. It usually consists of a nacelle, a tower, a yaw drive, a rolling bearing and a brake. Its functions are mainly yaw and brake functions. Yaw function: when the wind direction changes, the yaw drive drives the nacelle to rotate relative to the tower, so that the nose always faces the direction of the incoming wind; braking function: when the nose faces the direction of the incoming wind or other required positions, the braking provided by the brake Power, prevent the nacelle from deviating from the target position relative to the tower under the action of inertia and external load, and ensure the safe and reliable operation of the wind turbine. [0003] The Chinese patent "A Sliding Yaw Bearing for Lar...
