they have teeth
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***
The main function of gears is to provide torque. Low gears have fewer teeth than the ring gear. High gears have more teeth, so they are the opposite.
The # of teeth on the ring gear and the pinion gear. There is always more teeth on the ring gear then the pinion gear. And the way you determine the gear ratio is devide the # of teeth that's on the pinion gear into the # of teeth that's on the ring gear and that will be the gear ratio. The 4 gears that are the same size and run together is called the spider gears. Do not count those gears they have nothing to do with the gear RATIO.
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.
Yes it is.
Gears are wheels with teeth that fit together.
Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
Gears. A comb.
gears mesh with gears both have external teeth where as spline meshes with internal teeth .both are used to transfer torque.
if they dont the gears will tear the teeth out of each other very fast
They need to have that shape to engage the chian properly
