The number of revolutions of a driving gear relative to the number of revolutions of the driven gear For example, if a driving gear makes four revolutions while its driven gear makes one, the gear ratio is 4: 1
the formula is: the number of teeth on input gear divided by the number of teeth on output gear
The ratio of engine RPM's to rear wheel RPM's This determines the how fast the car will run on the race track as well as the fuel efficiency of a racecar More speed requires more fuel
In reference to the amount of times that the spool of a reel rotates while the handle is rotated once
The number of revolutions a driving (pinion) gear requires to turn a driven (ring) gear through one complete revolution For a pair of gears, the ratio is found by dividing the number of teeth on the driven gear by the number of teeth on the driving pinion gear
The number of rotations a driving gear must make while the driven gear is completing one revolution
Number, usually expressed as a decimal fraction, representing how many turns of the input shaft cause exactly one revolution of the output shaft Applies to transmissions, power takeoffs, power dividers and rear axles Example: If 2 5 revolutions of an input shaft cause one revolution of the output shaft, the gear ratio is 2 5: 1
The ratio between the sizes of the drive sprocket and the driven sprocket Different ratios can quickly be set by changing the size of the driven sprocket In non-shifter karts, this is the only way to change gears Also called the reduction ratio
