Custom Power Transmission Parts Plastic POM Tooth Spur Gears
Custom power transmission parts plastic POM tooth spur gears are widely used in various industries such as motors, electric cars, motorcycles, machinery, marine, toys, agricultural machinery, cars, and domestic appliances. These gears are made of POM (Polyformaldehyde), which is a high-density, high-crystalline, and linear polymer known as “Plastic Steel”. POM has excellent properties including wear-resistance, high hardness, chemical stability, and dimensional stability. It can be used as a substitute for metals like bronze, zinc, and tin.
The custom power transmission parts plastic POM tooth spur gears are manufactured using the cut gear method. They have a bevel wheel toothed portion shape and a hardened tooth surface for increased durability. Customization options are available for these gears.
Product Description
The custom power transmission parts plastic POM tooth spur gears are made from POM, an engineering plastic known for its outstanding properties. POM has a wide range of applications in industries such as automobile, electronics, and agriculture. It is used in car industries for mechanical parts due to its high mechanical strength, hardness, and wear-resistance. In the electronic and electric industries, POM is utilized for various products like electronic spanners, electronic scissors, and coal drilling machines. It is also used in agricultural machines for parts like manual sprayers and milk machine components.
POM has excellent mechanical properties, including a high tensile strength, compressive stress resistance, and impact strength. It has a low water absorption rate and good dimensional stability. The material’s density, tensile modulus of elasticity, and hardness make it suitable for various applications.
