Low-Noise Helical Gear - 20° Pressure Angle for Parallel Shaft Power Systems
Product Overview
This low-noise helical gear adopts a standard 20° pressure angle design, specially engineered for parallel shaft industrial power systems. Made of high-strength alloy steel and treated with professional heat treatment and precision grinding, it features continuous staggered meshing, uniform force bearing and ultra-low running vibration. Optimized for quiet and efficient transmission, this standard helical gear offers excellent universality and stability, widely used in industrial gearboxes, automation equipment and precision mechanical transmission systems.
Core Product Advantages
1. Standard 20° Pressure Angle, Balanced Transmission
Built with industrial standard 20° pressure angle, the gear forms a scientific and stable tooth profile. It effectively balances radial and axial force during operation, avoids stress concentration and transmission jitter, and ensures high meshing efficiency and stable power output. The standard design guarantees perfect compatibility with most parallel shaft transmission equipment.
2. Helical Tooth Structure, Ultra-Low Noise
Different from spur gears, the helical tooth design enables gradual and continuous multi-tooth meshing. It eliminates instantaneous meshing impact and greatly reduces operation noise and vibration. It delivers smoother and quieter running performance, fully meeting low-noise requirements for precision machinery and indoor automated production lines.
3. Heat-Treated Hardness & Strong Wear Resistance
Manufactured from premium alloy steel with integral quenching and tempering treatment, the gear features high tooth surface hardness and excellent overall toughness. The finely ground tooth surface reduces friction and abrasion during high-speed and long-cycle operation, maintaining stable transmission accuracy and extending service life effectively.
4. Stable Parallel Shaft Transmission
Precision-controlled tooth pitch and dimensional tolerance ensure accurate assembly and smooth meshing for parallel shaft systems. The gear runs stably with low energy loss and strong overload resistance, adapting to high-speed continuous operation and medium heavy-load industrial working conditions.
5. High Universality & Customization Available
Compliant with ISO and ANSI international standards, the gear features strong interchangeability for mainstream gearboxes and transmission machinery. We also provide OEM/ODM customization for module, tooth number, bore size and surface treatment to meet special equipment matching demands.
