They don't. Most racing trans have straight cut gears. Spur cuts are a little easier to shift.

What is the difference between spur gears and other gears?
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.
Why are gears called spur gears?
Spur Gears: a gear having straight teeth cut on the rim parallel to the axis of rotation.Gears: a disk, wheel, or section of a shaft, having cut teeth of such form, size, and spacing that they mesh with teeth in another part to transmit or receive force and motion.***A spur gear is a type of gear***
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.
For which mechanical systems are the spur gears used?
A gear is a simple machine, usually circular, with evenly cut teeth surrounding its perimeter. Spur gears are the most basic type and can be used in a wide variety of simple and complex machinery.
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.
State two reasons why helical gears are more favourable in a vehicle transmission than straight-cut spur gears?
Far more driving surface contact and easier gear selection.
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 does changing the gears on the center lathe do?
Changing the gears on a lathe enables it to cut certain pitches of threads.
What do you use to cut a rooster a spurs?
A cutting tool is actually not necessary. One can twist the spur and the hard outer "shell" will come off easily. The blood vessels inside are not damaged and a smaller spur will be left.
Why does your car whistle when reversing and grind when turning?
Unless there is an underlying fault with the gearbox/transmission (or else where), the most likely cause is that reverse gears tend to be "straight cut" rather than helically cut as forward gears are. The reason forward gears are helically cut it because straight cut gears are noisy, producing the typical "whine" when reversing. As a car spend the majoity of it's life traveling forward the additional expense of cutting the reverse gears helically in not seen as justifiable by most manufacturers. Grinding when turning is probably due to the brakes being almost worn out, and as the suspension/brakes flex when turning the backing plate for one of the pads is hitting the brake rotor/disk. I would suggest this is checked by a qualified person for safety reasons.
Is Hoffman in gears of war 3?
Yes Hoffman is in gears of war 3 during the E3 gameplay demo towards the end in the cut scene you can see the back of hoffman which shows his in the game.
