Advantages of POM Materials in Plastic Gear Manufacturing
POM (Polyoxymethylene) materials offer many unique advantages in plastic gear manufacturing, making POM an ideal choice for producing high-precision, high-performance plastic gears.
1. Excellent Wear Resistance
POM materials exhibit outstanding wear resistance, especially in long-running gear systems. During the contact between gears, POM reduces friction, extends gear lifespan, and minimizes wear.
2. Low Friction Coefficient
POM has a low friction coefficient, which reduces frictional losses in gear applications and lowers the temperature rise during gear operation. This characteristic allows POM gears to maintain better thermal stability and mechanical performance during high-speed operation, reducing excessive wear and thermal damage caused by friction.
3. Excellent Mechanical Strength
POM is a high-strength engineering plastic, with good tensile strength, impact strength, and compressive strength. In gear applications, POM can withstand higher loads and pressures, making it suitable for gear drive systems that require the transmission of substantial mechanical loads.
4. Excellent Dimensional Stability
POM has excellent dimensional stability under temperature and humidity changes. Plastic gears are often required to operate under varying environmental conditions. POM’s low moisture absorption and small thermal expansion coefficient allow it to maintain good dimensional accuracy even in environments with large fluctuations in temperature and humidity, preventing deformation caused by thermal expansion or moisture absorption.
5. Good Impact Resistance
POM materials have high impact resistance and maintain toughness even in low-temperature environments. In gear systems that operate at high speeds or are subject to external shocks, POM gears effectively resist impact and vibration, reducing the risk of cracking or damage.
6. Self-Lubricating Properties
POM is self-lubricating, which reduces the need for external lubricants on the gear contact surfaces, simplifying gear maintenance and reducing the overall maintenance complexity.
7. Lightweight Material
Compared to metals, POM has a lower density, making it lighter than metal gears. This lightweight feature makes POM gears perform excellently in applications where weight sensitivity is crucial.
8. Corrosion and Chemical Resistance
POM is highly resistant to many chemicals, maintaining stable performance even in harsh environments. It has good resistance to water, oil, solvents, and other chemicals, making it suitable for gear applications that require high environmental durability.
9. Noise and Vibration Reduction
Due to its low friction coefficient and high toughness, POM gears effectively reduce noise and vibration during meshing. This makes them ideal for applications where low noise and smooth operation are essential, such as household appliances and office equipment. Using POM gears can improve the comfort and working environment of mechanical systems.
