Is planetary gears used for spur gear?
Planetary gears can be spur or helical gears.
What are the types of gears used in automobiles?
mostly helical gears !1.
What is the difference between helical gear and screw?
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.
Difference between herringbone gears and double helical gears?
they have no difference.. they are same
Why are helical gears more favourable than spur gears?
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.
What vehicles have gears?
All vehicles have gears.
What is a helical gear?
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
What is the formula in getting the diametral pitch of helical gears?
External diameter / number of gear = pitch
What is the benefit of fitting a straight cut gearbox?
none. Henry fords engineers found that helical cut gears for transmissions ran much quieter and the transmissions were easier to shift. The same year that ford went to helical cut gears they added syncromesh to the transmission.
Herring bone gears used when it required that?
herringbone gears are used when the speed requirement is even higher than that can be taken by the helical gears and they are even more noiseless and vibration free. This is because the bending moment that gets induced in the gear shaft of a helical gear is neutralised by another force acting against it in a herringbone gear.
Where are sliding gears used?
Sliding Gears in a transmission are straight-tooth spur gears with a taper (also known as a lead) to make engaging easier. Helical gears are mostly used in a transmission because spur gears produce gear noise and have a great strain on the teeth of the gear since only one tooth can be in contact at any given time. But because helical gears cannot be taken out of mesh, spur gears are used for the reverse gear because reverse spins the opposite way and cannot be in constant mesh.
What does a helical gear look like?
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.
