Details of Plastic Bevel Gears
Polyacetal Resin Bevel Gears, Ratio 1:1 - 5:1
Material: Polyacetal resin, die-cast.
Shaft angle set at 90°. Bores start from Module 1.5 and are precision-machined. These bevel gears are designed to operate exclusively as a pair at the specified ratio. Thermoplastic materials exhibit significantly greater thermal expansion compared to metals, a factor that must be accounted for when determining crown and flank clearance during gear installation. Crown clearance (Sk) is approximately 0.25 m, while flank clearance (Sc) is around 0.05 m. The thermal expansion coefficient is 1.1 × 10⁻⁴ 1/°C. Bevel gears are also offered with smaller bores or featuring a feather key groove.
Note on Gears Made of Polyacetal Resin: Due to the die-casting process, these components contain internal cavities. As a result, deep drilling should be avoided. When creating larger bores or grooves, these cavities may become exposed. In most cases, this does not compromise functionality.

Plastic bevel gears are a type of gear used to transmit power between two shafts that are positioned at an angle to each other. Made from plastic, these gears are lightweight and resistant to corrosion. Their self-lubricating property means they do not require additional lubricants for operation, making them suitable for applications where contamination risks exist, such as in food processing and medical equipment.

Benefits of Plastic Bevel Gears
Plastic bevel gears are versatile and reliable components utilized in various applications. Their lightweight, corrosion-resistant, and self-lubricating characteristics make them ideal for numerous industries. Key benefits include:
- Lightweight: They are significantly lighter than metal gears, simplifying installation and maintenance.
- Corrosion-resistant: Their resistance to corrosion makes them suitable for harsh environments.
- Self-lubricating: They operate without the need for additional lubricants, ideal for contamination-sensitive applications.
- Versatile: Available in a range of materials, sizes, and ratios for diverse applications.
- Reliable: They provide durability and reliability for various uses.
If you're in search of a lightweight, reliable, and versatile gear option, plastic bevel gears are an excellent choice. They come in various materials, sizes, and ratios to fit multiple applications.
