The raw material of nylon gear is polyamide (PA, commonly known as nylon), which is the first resin developed for fiber by DuPont company in the United States. It was industrialized in 1939.In the 1950s, we began to develop and produce injection molding products to replace metal to meet the requirements of downstream industrial products for lightweight and cost reduction.PA has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, and low friction coefficient, has a certain flame retardant, easy to process, suitable for glass fiber and other fillers to enhance modification, improve performance and expand the scope of application.There are many varieties of PA, including PA6, PA66, PAll, PAl2, PA46, PA610, PA612, PAl010, and many new varieties of semi-aromatic nylon PA6T and special nylon developed in recent years.Suitable for making all kinds of switches, gears, components of household appliances, electronic facilities, large automotive electronic connectors, connector and hand-controlled electric tools.
Nylon gear features
(1) High strength, can withstand the load for a long time.
(2) Excellent resilience, can be tortuous without deformation, together with patience, withstand repeated impact;
(3) Wear-resisting self-smoothness, providing better operation function than bronze, cast iron, carbon steel and phenolic platen in oil-free or (deoiling) smooth operation, reduce consumption and save energy.
(4) Noise absorption and shock absorption. The modulus of MC nylon gear is much smaller than that of metal, and its attenuation to motion is large, providing a useful way to avoid noise specific effect better than metal.
(5) Compared with metal, MC nylon gear has low hardness and does not damage the grinding parts.
Nylon gear functions
Nylon gear has the remarkable function, including mechanical function and heat resistance, abrasion resistance, resistance to chemical medicine since temperament and smoothness, and conflict coefficient is low, there must be flame retardant, easy processing, suitable for reinforced with glass fiber and other packing, progressive function and extended use of planning, secondly the overload maintenance function, when the torque is too big, gear damage, power transmission and continuously maintain the lower equipment or personal safety, reduce the lose.Nylon has no poison, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, so it is widely used to replace copper and other metals in the manufacture of bearings, gears, pump blades and other parts in machinery, chemical industry, surface, automobile and other industries.
