Abstract

The invention discloses a yaw brake pad made of various materials. The yaw brake pad is composed of a steel back (1) and a friction layer (2), and the friction layer (2) is formed by sequentially arranging a heat-resistant layer (21), a friction-resistant layer (22) and a denoising protection layer (23) from inside to outside. The heat-resistant layer (21) contains boron-modified phenolic resin and vanadium trioxide, so that hardness, heat resistance and instant high temperature resistance of the friction layer are improved; the friction-resistant layer (22) contains steel wool fibers, quartz sand and potassium hexatitanate, so that friction coefficient and friction resistance of the friction layer are improved; the denoising protection layer (23) contains materials, large in nonmetal content, like flake graphite, molybdenum disulfide and antimony sulfide, so that the yaw brake pad is low in noise during working, and noise inside the yaw brake pad can be shielded. Friction performance, friction resistance and denoising effect of the yaw brake pad are obviously improved, service life of the yaw brake pad is longer than that of a common yaw brake pad, and the only defect of the yaw brake pad is that contact parts are worn slightly.
