AI Technical Summary

⚠Technical Problem

Existing gearboxes suffer from low production efficiency, high cost, and poor reliability during the production process. In particular, all-plastic gears are prone to stripping and tooth breakage, and the plastic-copper process is costly and inefficient, making it difficult to balance production efficiency and cost control.

⚗Method used

The system adopts a hybrid plastic and metal structure. High-load gears are made of metal materials, while low-load gears are made of polyoxymethylene plastic materials. Through powder metallurgy, mixing, high-pressure pressing, precision sintering and heat treatment, the system ensures that the gear performance meets the requirements and rationally allocates the number and materials of gears in the core transmission position.

🎯Benefits of technology

It achieves precise matching between materials and load conditions, improves the structural strength, wear resistance and dimensional stability of gears, reduces manufacturing costs, improves the operational stability and durability of products, and balances production efficiency and quality consistency.
