Abstract
The invention provides a yawing brake block and a preparation method thereof and relates to the technical field of a friction material. The yawing brake block is prepared from the following raw materials in parts by weight: 70-75 parts of polyether-ether-ketone, 10-20 parts of carbon fibers, 3-5 parts of glass fibers and 3-5 parts of graphite. The yawing brake block can relieve the technical problems that a metal-based friction material is generally applied to the domestic and oversea wind driven generator yawing brake block but the metal-based friction material is easy to rust, damage the mate plate and generate squeal. The yawing brake block can achieve the technical effects that the mechanical property and high temperature resistance are greatly promoted, the hardness of the yawing brake block is greatly reduced, the mate plate abrasion is reduced, the noise pollution is reduced, the friction stability and the working condition adaptation thereof are improved and the yawing brake block can meet the requirement for yawing low-velocity braking of a wind driven generator.
Description
technical field [0001] The invention relates to the technical field of friction materials, in particular to a yaw brake pad and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the rapid development of the economy, human demand for electricity continues to expand. The use of non-renewable energy sources such as coal and oil to generate electricity is facing the dilemma of increasingly scarce resources. As a green and clean energy, wind energy not only conforms to the direction of international energy reform, but also is a renewable resource, which is also of positive significance to environmental protection, and has been valued by more and more countries. [0003] In the process of wind power generation, it is necessary to adjust the direction of the blades due to the change of the wind direction, and fix the blades of the wind power generator to the most ideal direction of the wind force, so as to ensure the max...
