Title:
BEARING ASSEMBLY FOR WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2023/123506
Kind Code:
A1
Abstract:
A bearing assembly for a wind turbine, comprising: a rotating shaft (1) connected to a generator rotor, a bearing seat (2) connected to a generator base, and a front bearing component (31) and a rear bearing component (32) that are disposed between the rotating shaft (1) and the bearing seat (2). Both the front bearing component (31) and the rear bearing component (32) are sliding bearings (3); each sliding bearing (3) comprises a bearing body (36) and multiple radial pads (33), the multiple radial pads (33) being fixedly mounted on the inner side of the bearing body (36) and being arranged at intervals in the circumferential direction of the rotating shaft (1); the inner side surface of each radial pad (33) is a radial bearing surface bearing a radial load of the rotating shaft (1), and the radial bearing surface is provided with a first wear-resistant insulating layer (331). Thus, a shaft current insulation effect is improved, and the operation and maintenance are convenient.
