Product Description

Forged Steel AISI 4140 Gear Hobbing Doubel Helical Gear Wheel-Double Helical Gears

1) Features of Double Helical Gears

  • Double Helcial gear 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.

2) Description of double helical gear

Double helical gear with both left hand and right hand helical teeth.

The double helical form balances the inherent thrust froces.
