Description
Technical Field
The invention relates to the technical field of polymer composite materials, in particular to a polymer friction plate and application thereof in a wind power sliding bearing.
Background
The wind power yaw brake has the following functions in the wind turbine generator system: when the wind direction changes, the yaw brake pressure is released, and a certain damping force is kept by using lower working pressure, so that the fan is ensured to run stably, and the damage of a fan gear and a connecting structural member is avoided. When the direction of the fan is adjusted in place, the yaw brake is pressurized to use larger working pressure, so that the fan is always aligned to the wind direction, and the wind direction deviation is avoided, and the wind power efficiency is reduced.
Early wind-powered electricity generation yaw brake mainly takes initiative formula as the main part, and the fan adopts ball bearing mode to bear fan cabin, generator, upper portion fan weight such as blade, and wherein yaw friction disc mainly plays friction damping effect. Along with the reform of fan design theory, transition is towards slide bearing mode now, and the weight of fan upper portion cabin, generator and blade is born by the friction disc promptly, has reduced the input of driftage bearing, but has put forward higher requirement to the friction disc.
At present, more than 90% of fan main machine manufacturers adopt a sliding bearing mode, so that the market demand of friction plates is greatly increased, but the existing resin-based friction plates have the problems of low mechanical strength and easy fragmentation, so that the friction plates with high mechanical strength and good impact toughness are necessary to be provided, and meanwhile, a large amount of heat is generated due to friction, so that higher requirements are also provided for the heat resistance of the friction plates.
Along with the continuous development of materials, researchers find that polyphenylene sulfide (PPS) has good heat resistance, chemical resistance and flame resistance, but has the defect of poor impact toughness, while PA66 has good wear resistance and impact toughness, so that a composite material obtained by blending PPS and PA66 has good characteristics of both, not only has good heat resistance, chemical resistance and flame resistance, but also has good wear resistance and impact toughness, and is more suitable for being used as a base material of a friction plate. However, the greatest problem is that the PPS and the PA66 are easy to generate serious phase separation phenomenon in the temperature reduction process after the processing of the composite material, so that the bonding force of the two-phase interface is weaker, and the tensile strength, the impact strength and the friction coefficient of the composite material are not ideal.
