Double helical gears
Double helical gears are more difficult to produce due to their more complicated shape and hence more expensive to produce than spur gears.
Double helical gears are used in many applications such as cranes, fluid pumps and power transmission to the propulsion screws in military ships for a quieter and less vibration operation.
Our maximum diameter of external double helical gear is 1370mm (54 inches) * maximum face width 250mm (10 inches) with 30 degree helix angle. We have a wide selection of different pitch cutters.
