Yaw vibration noise digestion device for sliding bearing of wind generating set

Abstract

A yaw vibration noise digestion device for a sliding bearing of a wind generating set comprises a yaw gear ring, a main rack, lateral supports, a yaw gear ring upper surface anti-vibration element bracket assembly G, a special assembly F, an anti-vibration element E, a yaw gear ring lower surface anti-vibration element bracket assembly, a special assembly B and an anti-vibration element. The anti-vibration element E is mounted on the bracket assembly G. The special assembly F withstands the anti-vibration element E which makes contact with the upper fraction face of the yaw gear ring through the special assembly F. The bracket assembly G is connected with the main rack. The anti-vibration element is mounted on the bracket assembly. The special assembly withstands the anti-vibration element which makes tight contact with the lower friction face of the yaw gear ring through the special assembly. The bracket assembly is mounted on the lateral supports. By adoption of the yaw vibration noise digestion device, the vibration noise problem universally existing in the yaw process is solved and is not prone to appearing repeatedly, and the yaw vibration noise digestion device has the absolute advantages in technical modification and subsequent maintenance charge.

Description

Technical field [0001] The invention belongs to the field of wind power generation, in particular to a device for eliminating yaw vibration and noise of a sliding bearing of a wind power generating set. Background technique [0002] At present, wind turbines usually adopt an upwind yaw control system to achieve the wind problem of the wind turbine. The yaw bearing is an important part of the yaw system of wind turbines. It usually adopts rolling bearing and sliding bearing structure. Among them, sliding bearing is mainly composed of yaw gear ring, lateral support, upper sliding block and lower sliding block. composition. Due to many reasons, the sliding bearing type yaw system unit generally has vibration and noise problems during the yaw process. Once the yaw vibration noise occurs, it is difficult to eliminate it, which seriously affects the safety and reliability of the unit. A large number of studies have shown that the generation of yaw vibration and noise is mainly caused...
