Normalizing AISI 4140 Double Helical Gears Forging Steel Herring Bone Gear

Forging Steel Normalizing AISI 4140 Double Helical Gears-Gear Wheel

1) Description of double helical gear

The double helical gear consists of two identical gears articulated on the same shaft and having

teeth in opposite directions (one has a left-hand helix and the other has a right-hand helix).

2) Characteristics of double helical gear

• The resulting thrust force developed in a double helical gear is zero.
• The double helical gear can transmit greater power.
• The high helix angle can be used advantageously in double helical gears.
• The double helical gear can provide greater efficiency.
