Abstract
A bearing lubrication structure for a wind power gearbox includes a housing, a bearing, a planet carrier, and an oil scraper assembly. The planet carrier is rotatably disposed on the housing through the bearing. A first end face of the planet carrier and a second end face of the housing form a receiving chamber. The oil scraper assembly is disposed on the second end face and is located in the receiving chamber. The oil scraper assembly includes an oil scraper member. The oil scraper member is configured to, when the planet carrier rotates, collect oil from the first end face and make the oil flow into the bearing.
