specific Embodiment

[0057] like figure 1 and figure 2 As shown, the wind turbine yaw brake includes a caliper body 1, and a mounting hole is opened on the caliper body 1. The mounting hole is a through hole, and the openings at both ends of the mounting hole respectively form outer openings 6 for setting away from the brake disc 2. and an inner opening 7 for arranging close to the brake disc 2 . The wind turbine yaw brake also includes a friction plate 3 for friction with the brake disc 2 to provide damping torque for the yaw of the wind generator. The friction plate 3 has a friction surface that cooperates with the brake disc 2 . The friction plate 3 includes a base body 14 and a friction layer arranged on the base body 14. A groove 13 with a certain depth is provided on the end of the base body facing away from the friction layer. Hole 17. When the friction plate 3 and the brake disc 2 rub against each other, it is actually the friction layer provided on the base body 14 that rubs against t...

Abstract

The invention relates to a wind-driven generator yaw brake and a wind-driven generator. The yaw brake of the wind power generator comprises a clamp body and a friction plate, wherein a mounting hole is formed in the clamp body, the mounting hole is provided with an outer side opening and an inner side opening, the outer side opening is used for being far away from the brake disc, the inner side opening is used for being close to the brake disc, the friction plate is provided with a friction surface used for being matched with the brake disc, an elastic piece used for applying elasticity to thefriction piece to maintain the friction piece to be tightly pressed with the brake disc is arranged in the mounting hole the yaw brake of the wind driven generator further comprises a threaded adjusting piece which is arranged on the clamp body in a threaded mode, and the elastic force applied to the friction plate by the elastic part is adjusted by screwing the threaded adjusting part. Accordingto the technical scheme, the technical problem that friction plates in the wind driven generator are inconvenient to detach in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator yaw brake and a wind power generator. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy. The yaw system is an important part of the wind turbine. The yaw system has two main functions. One is to cooperate with the control system of the wind turbine to make wind power The wind rotor of the unit is always in the windward state, making full use of wind energy to improve the power generation efficiency of the wind turbine; the second is to provide the necessary locking torque to ensure the safe operation of the wind turbine. During the yaw process of the wind turbine, under a certain oil pressure, the two friction plates of the yaw brake are clamped on both sides of the yaw brake disc and rotate relative to each other, providing a certain damping torque, but at the same time causing friction ...
