The shape is known as an involute
the shape is analogous to unwinding a piece of string from a spool representing
the base circle diameter of the gear, imagine your pencil at the end of the string and the string kept tight during unwinding, unwind until line meets OD of gear, then apply blend radius at base circle, then mirror about tooth centre line for full tooth profile.

Which is the most efficient gear?
Spur Gear is the most efficient
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.
Is planetary gears used for spur gear?
Planetary gears can be spur or helical gears.
What is the purpose of a spur gear?
One of the most common types of gears is the Spur Gear. They are most round with teeth along the edging. Spur Gears are used in oscillating sprinklers or fans, windup clocks, washing machines and dyers.
What is a gear tooth?
There is a picture of a gear in the related link. a gear tooth is one of the things on the outside of the gear that sticks out. This gear has 18 teeth.
How do you call a trace of a point on a circle that rolls and slips?
Not certain what you mean but try google / involute curve , then click on the involute curvethe involute curve is the fundemantal shape of (amongst others) a spur gear tooth profile, generated from the gear base circle diameter.
What are the teeth of gear called in technology?
It is called a gear tooth. There can be many types of teeth based on the gear design; such as spur, helical, straight bevel, spiral bevel, hypoid, and several others.
Gear in watch is example of?
A spur 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.
Which is the most efficient gear?
Spur Gear is the most efficient
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
When was the spur gear invented?

Why reverse gear is spur?
Reverse gear is spur because it has to slide, sliding mesh gearbox uses spur gears. Because if it was constant mesh gear (helical) it could not slide in and out, therefore it could not go in the opposite direction of rotation.
Is planetary gears used for spur gear?
Planetary gears can be spur or helical gears.
What is gear geometry?
The relationship between the two shafts is actually defined by the helix ....Racks also feature in the theory of gear geometry, where, for instance, the tooth shape ...
