High-Performance Gears & Shafts for New Energy Vehicles

Product Overview

This series of high-performance gears and shafts are core transmission components custom-designed for the reduction gearbox in new energy vehicles. Manufactured from premium alloy steels and subjected to advanced heat treatment and precision grinding processes, they are engineered to meet the electric drive system's extreme demands for high efficiency, low noise, long service life, and high power density. They are the key to ensuring the reliability and superior performance of the e-drive assembly.

Core Product Advantages

l Advanced Material Science

Strictly utilizes high-quality alloy steels such as 40Cr, 20CrMnTiH, and 20Cr, ensuring excellent core toughness to withstand impact loads from high torque.

l Leading Heat Treatment Technology

Employs advanced processes like through carburizing quenching or tooth surface induction hardening. This creates an extremely hard and wear-resistant surface (typically above HRC 58-62) while maintaining a tough and ductile core, achieving the ideal "hard shell with a tough core" properties.

l Ultra-Precision Manufacturing & Performance

Tooth surfaces undergo precision grinding, consistently achieving JIS N7 grade or higher accuracy. This ensures smooth meshing, significantly reduces transmission noise and vibration, and improves overall transmission efficiency.

The combination of a hardened surface, a tough core, and high precision results in componens with exceptionally high load capacity, superior wear resistance, and an extended operational lifespan.

l Extensive Compatibility

Covers a broad module range from 0.8 to 20, demonstrating strong design and production capability to provide perfectly matched transmission solutions for various e-drive systems with different power and torque requirements.
