China Suppliers Factory Metal Inlaid Helical Gear for Precision Transmission Applications
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. If you need more accurate matching or customization scheme, you can provide equipment conditions and technical requirements, and we will design it for you~
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 are the benefits of combining a metal shaft with a plastic gear?
This hybrid design combines the high strength, rigidity, and torque transmission stability of a metal shaft with the lightweight, low noise, and self-lubricating properties of engineering plastics.
Which engineering plastics are used for the gears?
We primarily use high-performance engineering plastics like POM (Polyoxymethylene), which offer excellent mechanical strength, fatigue resistance, and low friction performance.
Can these helical gears operate in high-temperature environments?
Yes, depending on the material selection. While standard POM is suitable for moderate temperatures, we can customize gears using specialized high-temperature resistant plastics if your application demands it.
Do you provide samples for testing before placing a bulk order?
Yes, we can provide prototype samples based on your specifications for testing and validation to ensure they meet your performance requirements before mass production.
