Durable Plastic POM Bevel Gear

The Durable Plastic POM Bevel Gear is a high-quality engineering plastic gear made of Polyoxymethylene (POM). It is widely used in various industries, including motor, electric cars, motorcycle, machinery, marine, toy, agricultural machinery, and cars. The gear is designed with a soft tooth surface and is an external gear. It is manufactured using the rolling gear method and has a double helical gear shape.

POM, also known as Polyformaldehyde, is a non-side-chain engineering plastic that is known for its excellent properties. It is often referred to as “Plastic Steel” due to its wear-resistance, high hardness, anti-impregnant, good rigidity, chemical stability, isolation resistance, and dimensional stability. POM can be used as a replacement for metals like bronze, zinc, and tin.

There are different variations of POM. POM-H, which is often copolymerized with ethylene oxide, has better high crystalline, mechanical strength, and rigidity compared to POM-C. On the other hand, POM-C has better low melting point, temperature stability, fluxion characteristic, and machining capability.

The Durable Plastic POM Bevel Gear finds applications in various industries. In the automobile industry, it is used in engine fuel systems, hose valves, radiator case covers, cooling fluid standby cases, water valves, oil boxes, pump impellers, gasification machine shells, and accelerator pedals.

In the electronic and electric industries, POM is widely used due to its lower power consumption, high dielectric strength, insulation resistance, and electronic arc resistance. It is used in electronic spanners, electronic scissors, coal drilling machine shells, switch handles, and various electronic devices.

The gear also has applications in the agricultural machinery industry, such as manual sprayers, seeders, milk machines, irrigation and drainage systems, valves, joints, and bushings.

Other fields where the Durable Plastic POM Bevel Gear is used include pharmacy and packing machines, construction industries, and more.
