What Are Nylon Spur Gears?
Nylon Spur Gears are a type of plastic gear widely used across industries for their exceptional properties. Made from engineering plastics like MC Nylon (a polyamide resin) and polyacetal (POM), these gears feature straight teeth on a cylindrical surface, making them ideal for transmitting motion and power between parallel shafts. Their importance spans industries such as food production, consumer electronics, chemicals, toys, and medical equipment, thanks to their lightweight design, rust-proof nature, and quiet operation.
Why Choose Nylon Spur Gears?
Key Advantages
- Lightweight: Compared to metal gears, Nylon Spur Gears significantly reduce the weight of machinery, enhancing efficiency.
- Rust-Proof: Unlike steel, nylon doesn’t corrode, making it perfect for humid or corrosive environments.
- Quiet Operation: Their inherent lubricity ensures smooth, noise-free performance, ideal for consumer electronics or medical devices.
- Self-Lubricating: Many nylon gears operate without additional lubrication when paired with metal gears, reducing maintenance costs.
- Cost-Effective: Injection molding allows for large-scale production at a lower cost.
Applications Across Italy
From food processing plants in Milan to toy manufacturing in Florence, and medical equipment production in Bologna, Nylon Spur Gears are a versatile choice. In Venice, where moisture resistance is key due to the humid climate, their non-rusting properties shine.
Materials Behind the Magic
FMP Company uses high-performance plastics like:
- MC Nylon: Known for enhanced strength and thermal stability, it’s a staple in our standard PS and PSA series.
- Acetal Copolymer (POM): A crystalline thermoplastic offering excellent chemical resistance and durability, used in our molded spur gears.
For demanding applications—such as those with large temperature fluctuations or heavy loads—we may incorporate metal hubs (e.g., S45C or stainless steel) fused or screwed to the nylon teeth, ensuring durability without sacrificing the benefits of plastic.
Mechanical and Thermal Properties
Here’s a snapshot of what makes these materials stand out:
| Property | MC Nylon | Acetal Copolymer |
|---|---|---|
| Tensile Strength | High | Moderate |
| Thermal Expansion | 9×10⁻⁵ /°C | Lower than Nylon |
| Chemical Resistance | Excellent | Excellent |
| Water Absorption | Higher | Lower |
Note: MC Nylon data is based on dry conditions; strength decreases with temperature rises or moisture absorption.
Dimensional Change Example
Consider a MC Nylon gear rack (1010 mm long) at 20°C. If the temperature rises to 40°C:
- Coefficient of Linear Expansion: 9×10⁻⁵ /°C
- Calculation: Dimensional Change = 9×10⁻⁵ × 1010 mm × 20°C = 1.818 mm
This elongation highlights the need to account for thermal and moisture effects in design—a consideration FMP’s engineers expertly handle.
