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.
