Seriously worn disc surface

Yaw brake disc repair steps

1. First, mill the worn surface of the yaw brake disc to remove the surface. For rough parts, the surface processing depth is 3-7.5mm, ensuring that the thickness of the yaw brake disc after processing is 22.5-23mm.

2. In order to ensure that the upper and lower clearance between the yaw brake disc and the yaw brake is within the range of 2-3mm, an 8mm thick insert will be welded on the upper surface of the yaw brake disc. The insert material It is QT400 and is made of the same material as the yaw brake disc, which ensures good welding performance between the insert and the yaw brake disc. The yaw brake disc basically has no deformation after welding. By welding the insert, the yaw brake can be compensated The gap between the disc and the brake pad can also increase the torsional strength of the yaw brake disc, while the wear resistance remains the same as before.
