Embodiment Construction

[0021] In the present invention, the working principle of the milling machine is used for reference, and the slotting device is fixed on the yaw brake disc, driven by a motor, and manually fed to slot the yaw brake disc.

[0022] The invention comprises a bracket, a milling cutter, a motor driving mechanism for driving the milling cutter to rotate and a manual feeding mechanism. Refer to attached figure 1 As shown, the bracket 1 is made of two shorter square steels (the square steels can be cut from thick steel plates). The slot 7 and the hole for installing the fixing bolt 8, when the yaw brake disc is placed at the U-shaped slot 7, the slotting device is fixed on the yaw brake disc with the fixing bolt 8. The motor drive mechanism includes a 380V small motor 2, a belt 3 and a pulley 4. The belt 3 is connected to the power output shaft on the motor 2 and the pulley 4. The milling cutter is connected to the pulley 4, and the installation height can be adjusted, so that by sta...

Abstract

The invention discloses a slotting device for a yaw brake disc of a wind generating set. The slotting device comprises a bracket, a milling cutter, a motor driving mechanism and a manual feeding mechanism, wherein the motor driving mechanism and the manual feeding mechanism are connected with the milling cutter, the motor driving mechanism supports the bracket in a sliding manner, the manual feeding mechanism is fixed on the bracket and is used for driving the motor driving mechanism to drive the milling cutter to move forwards or backwards, and the forward and backward moving directions of the milling cutter are accordant with a slotting direction of the brake disc. According to the slotting device, the brake disc is slotted by virtue of the milling cutter, and the sizes and depths of parallelism of slots are uniform, so that the security is high; furthermore, the slotting device is simple in structure and is convenient to machine, popularize and apply and easy to operate.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a yaw brake disc slotting device for a wind power generating set. Background technique [0002] During the yaw process of the fan, the friction plate of the brake and the brake disc produce powder, which is technically required to be able to discharge the powder. Although there are flutes on the surface of the friction plate, some powder will still stick to the surface of the friction plate. Since the friction plate is an organic material, under the heat and pressure generated during the friction process, a hard layer, commonly known as "glaze layer", is formed, which changes the friction coefficient and causes abnormal yaw noise. [0003] The traditional solution is to replace the friction plate or remove the friction plate for grinding. The above solutions are only effective in the short term. After the unit has been running for a period of time, the surface of t...
