20CrMnTi |
The Alloy Steel (20CrMnTi) Worm Shaft is manufactured from 20CrMnTi alloy steel, designed for high-load transmission systems. Through customized design and heat treatment processes, it delivers consistent mechanical properties and wear resistance, meeting the demands for precision and durability in industrial drive applications.
Product Characteristics
Material Composition: 20CrMnTi alloy steel containing chromium, manganese, and titanium, ensuring uniform microstructure and hardened surface layers.
Heat Treatment Process: Carburizing, quenching, and low-temperature tempering achieve a surface hardness of HRC 58-62 while maintaining core toughness.
Machining Precision: CNC grinding and precision forming technologies ensure tooth profile accuracy within ISO Grade 6 and axial runout under 0.02mm.
Structural Design: Customizable module (range: 1-10) and helix angle designs to fit various reducer and gearbox assembly requirements.
Product Advantages
Fatigue Strength: Combined material and heat treatment enable a fatigue limit load of 980MPa under single-cycle testing, suitable for continuous operation.
Wear Resistance: Carburized layer depth of 0.8-1.2mm results in a wear rate below 0.005mm³/(N·m) when engaged with worm wheels under lubrication.
Installation Compatibility: Shaft ends can be machined with keyways, splines, or threads for direct assembly with bearings and couplings.
Application Fields
Industrial Reducers: Used as drive shafts in worm gear reducers and cycloidal pinwheel reducers.
Heavy Machinery: Suitable for transmission systems in mine hoists and port crane rotation mechanisms.
Automation Systems: Integrated into robotic rotary units and CNC indexing plates for precision positioning.
