How do you count the number of teeth in a sprocket?

The easiest way to calculate sprocket ratio is to count the number of teeth on both the driving and the driven sprockets and divide the first by the second. This ratio tells you how many times the driven sprocket turns for every revolution of the driving sprocket.

What is a gear module?

“Module” is the unit of size that indicates how big or small a gear is. It is the ratio of the reference diameter of the gear divided by the number of teeth. … Assume that there are two friction pulleys in contact whose diameters are equal to the reference diameters.

How do sprockets affect speed?

Substituting a larger front or smaller rear sprocket lowers the ratio (sometimes called “taller” gearing), resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm (“shorter” gearing).

How do you pick a sprocket size?

Determine the number of teeth of the small sprocket. The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. More than 15 teeth on the small sprocket is recommended. The number of teeth on the large sprocket should be less than 120.

How do sprockets increase speed?

You can gear up by using a smaller rear sprocket or a larger countershaft/front sprocket. Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front sprocket. Gearing down reduces speed and increases the final drive ratio.

What is the pitch of a sprocket?

Sprockets are designed for use with a specific chain. All chains are made to a given standard—with ANSI being the most common in the U.S. Each chain is identified by “pitch,” which refers to the measurement from one roller-pin center to the next roller-pin center of a given chain.28 мая 2012 г.

How is PCD sprocket calculated?

  1. P. = Chain Pitch.
  2. N. = Number of Teeth.
  3. Dr. = Roller Diameter ( See Table)
  4. Ds. = (Seating curve diameter) = 1.0005 Dr +
  5. R. = Ds/2 = 0.5025 Dr + 0.0015.
  6. A. =
