Double Helical Gears
A helical gear is actually a cylinder with teeth that spiral around the diameter, instead of being straight (as in a spur gear). Helical gears normally turn shafts that are parallel to one another. Helical gears will run smoother and quieter than spur gears.
We have the capacity to manufacture helical gears as small as less than an inch in diameter to larger than 100” in diameter. We can make helical gears integrated (as in one piece) with a shaft. The gear teeth can be hob cut, or for greater precision the gear teeth can be ground.
A double helical gear is actually another name for a herring bone gear (a side by side combination of two helical gears of opposite hands).
