Helical gears are similar to spur gear except it's teeth are slant. They have good load distribution, less noise and less wear compare to spur gear.
the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth
Double helical gear
Spur gears have straight teeth while helical gears have curved teeth. Generally, helical gears are usually quieter and smoother in operation, while spur gears are easier to make and much less expensive.Helical gears are stronger than spur gears.
Planetary gears can be spur or helical gears.
To remove helical gears from a shaft, first ensure the assembly is properly supported and secured. If the gear is fixed with a key, remove the key using a suitable tool. Then, use a gear puller to apply even pressure and gently extract the gear from the shaft. If the gear is stubborn, heating the gear or applying penetrating oil may help ease its removal.
A helical is a spur gear with an angle along the face to increase the gear contact ratio. The gear teeth are cut at angles http://www.motioncontrolguide.com/learn/faqs/gearboxes-and-gears/helical-gears/what-is-the-difference-between-a-helical-gearbox-and-a-straight-gear-tooth-gearbox/ hope this helps

A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.

herring bone gear (Double helical ) doesn't axial thrust
The flow difference in gear compares because it spurs for 5 hours.

Planetary gears can be spur or helical gears.
A hobbing machine is used for cutting gear teeth in gear blanks and for cutting worm, spur, or helical gears.
External diameter / number of gear = pitch
