Spur gears are cut with straight teeth. They can only transmit rotation between parallel shafts, and are relatively economical. Bevel gears have teeth cut on an angle. They transmit rotation between non-parallel shafts. Helical gears have curved teeth. They are generally quieter than spur gears, but are generally more difficult to make and more expensive.
Planetary gears can be spur or helical gears.
Spur gears give 180 degree drive, and worm gears give 90 degree drive.
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.
Advantages - Spur gears are simplest, easiest to design and manufacture and disadvanages i dunno :)
spur gears are used because there are many things such as bicycles that cant exist without a spur gear' > gearboxes, mechanical watches, cam drives
cane is a big piece and the spur is a small is a piece
its the same
In the differential.
You can see them in industries...
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.
They don't. Most racing trans have straight cut gears. Spur cuts are a little easier to shift.
