Advantages - Spur gears are simplest, easiest to design and manufacture
and disadvanages i dunno :)
Planetary gears can be spur or helical gears.
spur gears are used because there are many things such as bicycles that cant exist without a spur gear' > gearboxes, mechanical watches, cam drives
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.
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.
A spur gear is a type of gear characterized by its straight teeth that are parallel to the gear axis, designed primarily for transmitting power between parallel shafts. In contrast, an involute gear refers to the specific tooth profile used in many gears, including spur gears, where the tooth shape is derived from an involute curve. This profile allows for smooth engagement and efficient power transmission, minimizing wear and noise. Essentially, while all involute gears can be spur gears, not all spur gears use the involute tooth profile.
