1)Descriptions of Double Helical Gear

A Double Helical Gear consists of two identical helical gear teeth sets arranged symmetrically with opposite helix angles. This design creates a V-shaped tooth pattern, resembling two mirrored helical gears joined together.

2)Features of Double Helical Gear

The axial (thrust) forces generated by each helix cancel each other out within the gearbox, eliminating net axial load on the bearings.

3)Advantages of Double Helical Gear

• Eliminated Thrust Force:Opposite helix angles produce counteracting thrust reactions, neutralizing axial forces internally without relying on bearings.
• Zero Net Axial Load on Bearings:Bearings experience minimal axial stress, enhancing lifespan and reducing design complexity.
• High Power Transmission Capacity:Double tooth engagement distributes load more evenly than spur or single helical gears, enabling higher torque/power transfer.
