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***
Planetary gears can be spur or helical gears.
When one spur gear is used to turn several other spur gears, it is referred to as a "gear train." In a gear train, the driving gear (the one with the spur) transfers motion and torque to the driven gears, allowing for the transmission of power through multiple gears. This arrangement is commonly used to achieve different speed and torque outputs in machinery.
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
You can see them in industries...
In the differential.
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.
They don't. Most racing trans have straight cut gears. Spur cuts are a little easier to shift.
Spur gears give 180 degree drive, and worm gears give 90 degree drive.
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.
Spur Gears.
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.
