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.
spur gears have straight teeths.
whereas helical gears have tooths crossed at an angle.
spur gears are very noisy and helical gears have greater load capacity than the spur gear of same size. This is because in spur gears take the entire load in the tooth whereas the helical gears distributes the same load on to the shaft hence the gear tooth itself takes less load than a spur gear of same size
Helical gear and screw pump are often interchangeable designations for a rotary positive displacement pump that moves fluids. In a single screw helical gear pump the gear looks like a screw and fits tightly into the casing in order to move the fluid axially along the screw. In a multiple screw helical gear pump two or more "gears" or screws intermesh with one another to pump a fluid axially or radially through the pump.
because the car moves fowards and backward
Helical gears are used because they run more smoothly and quietly than straight-cut gears.
Helical gears are stronger than spur gears.
A helical gear is stronger.
Because they are stronger than spur gears
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
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.
Planetary gears can be spur or helical gears.
both are same using for rotating the turbine initially
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.
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
The flow difference in gear compares because it spurs for 5 hours.

A bevel gear is cone shaped with the gear teeth placed vertically along the periphery. A worm gear is barrel shaped with the teeth spiraling along the length like a screw.
Double helical gear
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.
herring bone gear (Double helical ) doesn't axial thrust
what is
bevel gears are used for power transmitting between the shafts which intersect at some angel ( usually right angel) , but the spur gear is used for shafts which are parallel and coplanar.
Sparring gear is universal.
The driver gear has the input torque, and the driven gear has the output torque.
