DP 6.35 17CrNiMo6 Gear Grinding Doubel Helical Gear Set For Gear Redcuer
1) Description of Double Helical Gear
Double Helical Gear is characterized by a symmetric arrangement of two identical gear teeth with exactly
opposite helix angles.
2) Feature of Double Helical Gear
The double helical gear' axial forces in the gearbox negate each another.
3) Advantages of Double Helical Gear
They develop opposite thrust reactions thus cancel out the thrust force within the gear itself.
The net axial force that acts on the bearings is zero.Power transmitting capacity is very high.
By using this high pitch line velocities can be attained.
