Three kinds of engineering plastics application gears
TIME:2021-5-5
With the development of science and technology, gears have gradually changed from metal gears to engineering plastic gears. This is because engineering plastic gears have better wettability and wear resistance. It can reduce noise, control cost and reduce friction. Gear materials used in engineering plastics include POM, PA, nylon, peek, etc. At present, in the products of modern chemical industry, gears are general and important functional parts. Basically, different types of gears will be used in any products involving mechanical transmission.
The gear product for engineering plastics application is POM
Gears are common coil motor drivers for engineering plastics applications. Engineering plastic pomn2320 has a bending modulus of 2470mpa and a yield elongation of 9.4%; The friction resistance is 0.35, the interior of n2320003 is added with an improved easy to fall off model, and has good self wettability; Elastic die 2600mpa, grain size up to 70%, with good resilience, high dimensional reliability and high precision; Rashin creep modulus 1400MPa; Good chemical resistance, such as weak acid, alkali, aldehyde, oxynitride, ketone, ether, mineral oil and its standard fuel, without strong acid, strong alkali and ultraviolet radiation.
Gear products with high standard for tensile strength are engineering plastics and semi aromatic nylon
This gear needs to withstand high working strength, so the tensile strength standard of the material is high. Gv-5h tensile modulus exceeds 18000mpa; With 50% GF reinforcement, it has good dimensional reliability; The plate is PA66, which has good self wettability and can reduce the friction resistance between gears; It has good weather resistance and chemical resistance.
Peek gears for engineering plastics applications
PEEK material has strong corrosion resistance, aging resistance and solubility resistance; Characteristics of high temperature and high frequency high voltage line; Both toughness and stiffness; Standard and fine size; Radiation resistance, wear resistance and corrosion resistance: hydrolysis resistance, excellent wear resistance and anti-static insulation under ultra-high pressure and high temperature; High tensile strength standard parts. Its gears are specifically used in demanding application scenarios, such as automobile (including aviation) freight industry market, semiconductor device equipment, pressure sink valve plate and medical machinery.
