ISO 6-7 Grade Double Helical Gears for Mining and Agriculture

Description of Double Helical Gear: From the perspective of installation convenience and maintenance cost, double helical gear is a gear component with high tolerance for installation errors and less later maintenance workload. Its structural design reduces the complexity of installation and maintenance.

• No need to accurately adjust the axial clearance during installation
• Self-balancing of the axial force reduces requirements for bearing positioning accuracy
• Uniform wear of the gear teeth ensures long service life and reduced replacement frequency
• No need to deal with axial force-related components during maintenance, reducing difficulty and cost

During installation, even with slight axis parallelism errors, the symmetrical teeth of the double helical gear can adapt to small deviations through elastic deformation to ensure meshing stability. In long-term use, the uniform force distribution makes the wear rate consistent, requiring only routine inspection of tooth surface wear and lubrication status during maintenance.

Suitable for equipment with complex installation environments and limited maintenance conditions, such as conveyor drives for mining machinery and gearboxes for agricultural tractors.
