Embodiment Construction

[0013] The present invention will be further described now in conjunction with accompanying drawing.

[0014] see figure 1 and figure 2 , figure 1 , figure 2 Shown is an embodiment of the present invention, which is composed of a damping friction plate 1 and a cylinder 2 with self-lubricating properties. Among them, the damping friction plate 1 is composed of the following raw materials in parts by mass: graphite powder 0.5%-23.5%, petroleum coke 0.1%-15%, ultra-fine tin bronze powder and / or brass powder 0.1%-5%, Asphalt 0.2%-25%, the rest is filling powder. In addition, vacuum impregnation resin 2% is included. The damping friction plate 1 made of the above ingredients can be easily and firmly combined with other materials, and the adhesion is firm; it has self-lubricating properties, and the equipment (parts) slides lightly; the friction coefficient is moderate, the braking is stable, and there is less dust; Excellent wear resistance, long service life; thermal shock...

Abstract

The invention relates to a damper for wind power generation. The damper for wind power generation comprises a cylinder body and further comprises a damping friction plate with the self-lubricating performance. One face of the damping friction plate is fixed to the lower end of the cylinder body in a bonded or embedded manner. The other face of the damping friction plate is pressed on a connectingring plate of a tower cylinder. The damper has the beneficial effects of being simple in structure, stable in friction damping, low in cost and long in service life.

Description

technical field [0001] The invention relates to a sliding damping device of a yaw system for wind power generation, in particular to a damper for wind power generation. Background technique [0002] During the working process of the wind turbine, in order to make full use of the wind energy and maintain the full power state, the wind rotor must automatically rotate with the change of the wind direction, and always keep the wind rotor in line with the wind direction. In order to achieve the above goals, the nacelle must have a device to track the change of wind direction and drive the nacelle to rotate. This device is the yaw system. The yaw system usually consists of a wind direction detection controller, a yaw drive, a yaw brake and a yaw bearing, among which the wind direction detection controller, yaw drive and yaw brake are placed in the nacelle, and the yaw bearings are respectively placed in On the nacelle and the tower, the yaw drive motor drives the ring gear at the...
