Likewise, how do you calculate the number of teeth in a gear?
The ratio of a given pair of spur gearsiscalculated by dividing the number of teeth onthedriven gear, by the number of teeth on thedrivegear.
Similarly, how do you calculate gear modules? "Module" is the unit of size that indicateshowbig or small a gear is. It is the ratio of thereferencediameter of the gear divided by the number ofteeth. Assumethat there are two friction pulleys in contact whosediameters areequal to the reference diameters.
Similarly one may ask, how do you calculate gear reduction?
The “reduction” or gearratiois calculated by dividing the number of teeth on thelargegear by the number of teeth on the small gear.Forexample, if an electric motor drives a 13-tooth piniongearthat meshes with a 65-tooth gear, areduction of 5:1is achieved (65 / 13 = 5).
What does a 4.10 gear ratio mean?
When you hear people refer to numbers like 3.08, 3.73,or4.10, they're talking about the ratio ofthering-and-pinion gears in the rear axle—hence,thenumbers are more accurately 3.08:1, 3.73:1, or 4.10:1.Thatalso means that for every one turn of the ringgear,the pinion will turn 4.11 times.
