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

1) 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, and its structural design reduces the complexity of installation and maintenance.

2) Feature of Double Helical Gear

a) There is no need to accurately adjust the axial clearance during installation, and the self-balancing of the axial force reduces the requirements

for bearing positioning accuracy.

b) Uniform wear of the gear teeth, long service life, reduced replacement frequency;

c) There is no need to deal with axial force-related components during maintenance, reducing maintenance difficulty and cost.

3) Working Principle

During the installation process, even if there is a slight axis parallelism error, the symmetrical teeth of the double helical gear

can adapt to small deviations through elastic deformation to ensure the meshing stability; In long-term use, the uniform force distribution

makes the wear rate of the gear teeth consistent, and only routine inspection of tooth surface wear and lubrication status is required during maintenance.

4) Application of Double Helical Gear

It is suitable for equipment with complex installation environments and limited maintenance conditions,

such as conveyor drives for mining machinery and gearboxes for agricultural tractors.
