Problems solved by technology

In the process of operation, since the hardness of the yaw brake disc is greater than that of the friction plate, the wear of the friction plate will often be large. However, when maintaining, installing or replacing the yaw brake disc, it is often necessary to remove the entire brake disc and replace it. Therefore, it is extremely inconvenient to maintain, install or replace, and the installation cost is very high

Embodiment 1

[0023] Embodiment one, such as Figure 1 to Figure 2 As shown, a yaw brake disc of a wind power generating set includes a brake disc base 1 and a brake brake 2, the upper surface of the brake disc base 1 is fixedly connected with an upper brake disc, and the lower surface of the brake disc base 1 is fixedly connected with a lower end brake disc, A tower flange 3 is arranged below the brake disc at the lower end, and one end of the bolt 4 is movably connected to the bottom of the tower flange 3 through threads, and the other end of the bolt 4 passes through the tower flange 3, the brake disc at the lower end, the brake disc base 1 and the The upper brake disc is threadedly connected with a nut 6; the brake brake 2 is fixedly installed on the lower surface of the bed plate 7 of the generator set, and the clamping ends of the brake brake 2 are in contact with the upper brake disc and the lower brake disc respectively.

[0024] Therefore, when the upper brake disc or the lower bra...

Embodiment 2

[0025] Embodiment 2, based on the further improvement of Embodiment 1, the upper brake disc includes an upper inner inner ring brake disc 8 and an upper outer outer ring brake disc 9, the upper inner inner ring brake disc 8 and the upper outer outer ring brake disc 9 are arranged concentrically, and the lower end brake disc includes The lower end inner ring brake disc 10 and the lower end outer ring brake disc 11 are arranged concentrically; the fixing bolts 4 pass through the tower flange 3, the lower end outer ring brake disc 11, The brake disc base 1 and the upper end outer ring brake disc 9 are threadedly connected with the nut 6, and the clamping ends of the brake brake 2 are in contact with the upper end inner ring brake disc 8 and the lower end inner ring brake disc 10 respectively. The upper inner ring brake disc 8 and the lower inner ring brake disc 10 are respectively provided with a first groove 12 and a second groove 13, and the first groove 12 is provided with a th...

Embodiment 3

[0027] Embodiment 3, based on the further improvement of Embodiment 2, there are multiple upper inner ring brake discs 8 and lower inner ring brake discs 10, which are evenly distributed on the upper surface and lower surface of the brake disc base 1 respectively. By adopting the segmented design of the upper inner ring brake disc 8 and the lower inner ring brake disc 10, when wear occurs, the corresponding worn parts can be replaced individually, thereby greatly saving the replacement cost; and segmented The design is also convenient for the moving, tower installation and disassembly of components, which saves the hoisting cost of components, reduces the requirements for installation space, and facilitates operation and realization.

Abstract

The invention discloses a yaw brake disc of a wind turbine generator system. The yaw brake disc of the wind turbine generator system comprises a brake disc base and a brake; the upper surface of the brake disc base is fixedly connected with an upper end brake disc; the lower surface of the brake disc base is fixedly connected with a lower end brake disc; a tower flange is arranged under the lowerend brake disc; one end of a bolt is movably connected under the tower flange through a thread; the other end of the bolt penetrates through the tower flange, the lower end brake disc, the brake discbase and the upper end brake disc in sequence, and is in threaded connection with a nut; and a clamping end of the brake is contacted with the upper end brake disc and the lower end brake disc. The yaw brake disc of the wind turbine generator system overcomes the defects in the prior art; and as the brake disc is divided into an upper end inner ring brake disc and a lower end inner ring brake disc, and is segmented, when the wear occurs, one or several sections of brake disc assembled parts needing to be replaced are selected according to different worn parts, and the quick, effective and economical maintenance of the yaw brake disc is realized.

Description

technical field [0001] The invention relates to the technical field of yaw brake discs, in particular to a yaw brake disc of a wind power generating set. Background technique [0002] With the vigorous promotion of wind power generation technology, the research on each system of wind turbines tends to be refined and intelligent. As the main mechanical mechanism for maintaining variable pitch power generation, the performance of yaw system directly affects the safety, stability and utilization rate of wind power generation. [0003] However, in the existing yaw system, the brake is usually controlled to adjust the windward angle of the blade by clamping the yaw brake disc with the friction plate, so as to ensure that the pitch of the blade changes with the change of the wind force. In the process of operation, since the hardness of the yaw brake disc is greater than that of the friction plate, the wear of the friction plate will often be large. However, when maintaining, ins...
