In the realm of mechanical transmission, gear performance plays a decisive role in determining the operational efficiency and stability of equipment. Yuchen’s 3-module ground helical gears combine premium materials, advanced processing techniques, and strict quality control to deliver outstanding durability and performance across a wide range of industrial applications.

Premium Materials, Advanced Craftsmanship
Our 3M ground helical gears are manufactured using high-quality 20CrMnTi or SCM440 alloy steel.

20CrMnTi: This material offers nice overall mechanical properties after heat treatment, striking a balance between hardness, wear resistance, and toughness. It is well-suited for standard industrial transmission systems.

SCM440: Known for good strength, toughness, and fatigue resistance, this alloy performs reliably even under heavy loads, impacts, or high-speed operation, minimizing equipment failure and maintenance costs.

Forging is carried out using hot die forging to enhance material density and improve mechanical strength and durability. The wedge rolling process improves blank precision and reduces machining allowances, increasing manufacturing efficiency. Isothermal normalizing ensures nice hardness and microstructure for machining, reducing deformation during subsequent heat treatment and ensuring dimensional consistency.

CNC lathes are used for multi-position turning in a single setup, which enhances dimensional and positional accuracy. Tooth forms are processed through hobbing and shaping: hobbing for external gears and shaping for internal or complex profiles. Further precision is achieved through radial gear shaving and carburizing heat treatment to enhance surface hardness, wear resistance, and stress relief.

Grinding is performed using high-precision gear grinding machines, resulting in exceptional dimensional accuracy and less form deviation. A strict inspection protocol using advanced measurement tools ensures each gear meets quality standards before delivery.

Key Advantages and Performance Highlights
High Precision: Achieving DIN 6 or higher gear accuracy, the Yuchen 3M ground helical gears exhibit less tooth form and pitch errors. They enable high-precision motion control in CNC machines, automation lines, and other applications that demand exact positioning and repeatability.

Low Noise Operation: Optimized gear profiles and ground surfaces ensure smooth meshing between teeth, significantly reducing transmission noise and vibration—ideal for use in medical devices and precision instruments requiring quiet operation.

High Hardness and Wear Resistance: Thanks to premium materials and advanced heat treatment, the gears exhibit nice surface hardness and wear resistance. They perform stably over extended periods in heavy-duty, high-speed industrial applications, helping extend machine service life and reduce maintenance costs.

good Operational Stability: Rigorous design standards and precise manufacturing processes ensure stable power transmission. This reduces the risk of failures caused by unstable motion and improves overall equipment uptime and production efficiency.

Versatile Applications Across Key Industries
