Problems solved by technology

The cabin width of land wind turbines is subject to land transportation conditions, and the limit of transportation width cannot exceed 4.5m. Therefore, with the increase of unit power, the existing single-bearing yaw rotation scheme will not be able to meet the yaw system of wind turbines. usage requirements

Abstract

A yaw bearing assembly (1) and a wind power generator group. The yaw bearing assembly (1) comprises: a base (10), comprising a first base body (11) and a second base body (12) which are sleevingly connected and arranged coaxially; and a rotary connecting piece, connected to the first base body (11) and the second base body (12), wherein the rotary connecting piece comprises a first bearing (21) and a second bearing (22) which are arranged on the axis of the first base body (11) and the second base body (12) at an interval, and the first base body (11) and the second base body (12) are rotatably connected by means of the first bearing (21) and the second bearing (22). The yaw bearing assembly (1) may be used for a yaw system of a wind power generator group and may reduce the width of a cabin of the wind power generator group on the basis of meeting yaw requirements of the wind power generator group, thereby reducing cost and facilitating transport.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a yaw bearing assembly and a wind power generating set. Background technique [0002] Wind power is a kind of clean renewable energy, which has been paid more and more attention by countries all over the world. Since the wind direction of the wind field is constantly changing, in order to efficiently utilize wind energy, the impellers of the wind turbine must always be aligned with the wind direction during operation, and the yaw system is an important part of the wind turbine to capture the wind direction. All loads due to all gravity and wind loads on the nose of the unit. For this purpose, a yaw system is set in the wind turbine. The yaw system can cooperate with the control system of the wind turbine to make the impeller of the wind turbine yaw, so that it is always in the windward state, which can make full use of wind energy and improve the power generation efficiency ...
