4 Module 43T Double Helical Gears with ISO 8-9 Grade for Speed Reducer

DIN 18CrNiMo7 Steel 4 Module 43T Double Helical Gears For Speed Reducer

1) Description of double helical gear

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