Abstract

The invention relates to a braking pad, in particular to a vibration-damping, denoising and yaw low-speed braking pad for a yaw braking device of a wind generating set and a fabrication method of the braking pad. The vibration-damping, denoising and yaw low-speed braking pad comprises a steel backing and an abrasive layer attached to the steel backing, wherein the abrasive layer is fabricated by taking PTS (Phenolic Thermospheres) suspension method phenolic resin as a gluing agent, taking graphite, tin sulfide and copper sulfide as a lubricant, taking antimony trisulfide, zirconium silicate, silicon carbide and silicon dioxide as an abradant, taking potassium titanate whiskers, ceramic fibers, aramid fibers, carbon fibers, steel fibers and copper fibers as reinforced fibers, taking calcium carbonate, mica, vermiculite and foam ferrous powder as an inorganic filler, and taking cashew nut shell oil friction powder and rubber powder as an organic filler according to a wet method pressing technology. The braking pad has the advantages that component percentages of a friction material and a processing technology are reasonable; the braking sensitivity is high; the braking vibration is small; the friction noise is low; and the braking pad is provided with a pad abrasion alarm line.

Description

technical field [0001] The invention relates to a brake lining, in particular to a vibration-reducing and noise-reducing yaw low-speed brake lining used for the yaw brake of a wind power generating set and a manufacturing method thereof. Background technique [0002] The brake pad is an important part of the yaw brake, usually composed of a metal support plate and a friction material fixed on the metal support plate. The friction material can be formed by heating and pressing powdery materials such as fibrous materials, fillers and binders. However, due to the different formula components and proportions of the friction materials used, as well as the different selection of process parameters in the processing process, the traditional yaw brake will directly produce severe friction when the brake pad contacts the brake disc during the braking process. Vibration and strong friction noise. The friction surface of traditional brake pads is usually flat, which compresses the b...
