Abstract

The invention discloses a yaw system and a wind-driven generator set. The yaw system comprises a yaw bearing and a yaw driving mechanism. The yaw driving mechanism comprises an oil cylinder and a gear; one of the inner ring and the outer ring of the yaw bearing is provided with a gear ring, and the gear is fixedly mounted on the other of the inner ring and the outer ring of the yaw bearing and engaged with the gear ring; the first end of the oil cylinder is rotatably connected to the eccentric position on one side of the gear, and the second end of the oil cylinder is rotatably connected with the other of the inner ring and the outer ring of the yaw bearing. The yaw system effectively reduces the number of parts and the structural complexity, the integral weight and the manufacturing cost, easily achieves stability during the yawing process and can omit an opposing torque providing device and a yaw brake device to avoid waste of energy.

Description

technical field [0001] The invention relates to the technical field of fan yaw, in particular to a yaw system and a wind power generating set. Background technique [0002] A wind turbine (referred to as a fan) is a device that converts wind energy into electrical energy. A wind turbine is usually composed of an impeller, a transmission system, a generator, a yaw system, and a pitch system. Among them, the yaw system is mainly to deal with the influence of wind direction uncertainty. Specifically, under normal circumstances, when the impeller rotation plane is perpendicular to the airflow direction (wind direction), the wind energy that the fan can obtain is the largest, but the wind direction often Change, when the impeller rotation plane is not perpendicular to the wind direction, the yaw system needs to be used to make the impeller rotation plane perpendicular to (aligned with) the wind direction. [0003] The Chinese patent document numbered CN201320004154 discloses a t...
