PRODUCTS DETAILS

Structural and Material Advantages

Metal Shaft

Selected high-quality alloy steel, heat treated for reinforcement, with hardness and wear resistance, ensuring minimal deformation during long-term operation, and guaranteeing transmission stability.

Plastic Gear

Molded from engineering plastics (such as, POM), the lightweight design reduces transmission inertia, and the self-lubricating property of plastic can reduce meshing friction, extending the service life.

Transmission Performance

Tooth Engagement Precision

The helical gear design allows for “line contact” on the tooth surface, which is uniform compared to the “point contact” of straight gears, resulting in low noise and minimal vibration during transmission, suitable for scenarios with high requirements for silence and stability.

Transmission Efficiency

The combination of the rigidity of the metal shaft and the lightweight of the plastic gear reduces transmission resistance, with minimal energy loss, and more energy-efficient long-term operation.

Application and Customization Capability

Widely used in office equipment (shredder, printer), small machinery (toys, models, automation equipment) etc., can be customized according to the number of teeth, module, shaft diameter and other parameters according to demand, to meet personalized transmission needs.

Product Detail Page FAQ

Order & After-Sales
What information do I need to provide for customizing a gear/gearbox?
Please share details like application scenario (e.g., automotive/medical), required torque, speed, size constraints, material preferences, and operating environment—our team will tailor a solution.
What is the typical lead time for standard and customized products?
Standard micro precision planetary gear boxes have a shorter lead time (subject to inventory). Customized products (gears/gearboxes) usually take 2-4 weeks, depending on mold development and production complexity.
What materials are used for the metal-inlaid gear shafts?
We utilize high-quality alloy steel for the metal shaft, which undergoes specialized heat treatment for maximum hardness and wear resistance. The gears are molded from high-grade engineering plastics like POM (polyoxymethylene) to ensure lightweight and self-lubricating properties.
Why choose a combination of metal shaft and plastic gear?
This hybrid design delivers the best of both worlds: the metal shaft provides structural rigidity and high torque transmission capability without deformation, while the plastic gear reduces overall weight, lowers transmission noise, and decreases operation friction.
Can I get samples before placing a bulk customized order?
Yes, we can provide prototype samples based on your design specifications for testing and validation. Once the performance matches your system requirements, we will proceed with mass production.
Are these helical gears suitable for low-noise applications?
Absolutely. The helical gear design utilizes line contact instead of point contact, which distributes the load more smoothly and significantly reduces vibration and noise during high-speed operations.
