Product Description
DIN 18CrNiMo7 Steel Double Helical Gears
Product Overview
High-performance double helical gears manufactured from DIN 18CrNiMo7 steel, featuring 4 module and 77 teeth configuration specifically designed for industrial gearbox applications.
Double Helical Gear Design
Double helical gears consist of two helix angles with opposite hands, where axial thrusts oppose each other internally. This design eliminates thrust force transmission to shaft bearings while maintaining high load capacity and stable transmission performance.
Key Features
- Combines strength and quiet operation of helical gears
- Eliminates axial thrust forces through opposing helix angles
- High load capacity for demanding industrial applications
- Stable transmission performance under heavy loads
- Custom manufacturing options available
