2. Step 2: Determine Your Key Dimensions. …
3. Step 3: Draw the First Sprocket Tooth. …
4. Step 4: Use Circular Pattern to Finish the Sprocket.

## How do you calculate teeth on 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.

## How do sprockets increase speed?

To increase low end power, you should increase size of rear sprocket or decrease size of front sprocket. To increase top speed, you should reduce size of rear sprocket or increase size of front sprocket.

## 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. =

## How do you calculate the breaking load of a chain?

Multiply the chain’s working load limit by the cosine of the angle between the chain and vertical to get the adjusted limit. For example, if 1000 lb rated chains are at 45 degrees to the vertical their safe working load limit is reduced to 707 lbs.

## What is the pitch of a sprocket?

The teeth of the sprocket contact the surface of the bushings when the chain is wrapped around a sprocket. Pitch is the distance between the centers of two adjacent pins. Common pitches are 0.25”, known as #25, and 0.375” (#35).

## What sprocket is best for speed?

For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket. For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that’s true for higher gearing ratios, too).

## How many teeth does a sprocket have?

You get the gear ratio by dividing the number of teeth on the rear sprocket by the number of teeth on the countershaft sprocket. For example, a 13-tooth countershaft sprocket will divide into a 49-tooth rear sprocket 3.77 times.

## How do you draw gears?

Drawing meshing gears

1. Step 1: Start by drawing a horizontal centre line for both gears.
2. Step 2: Draw a vertical centre line for the driver gear on the left. …
3. Step 3: Calculate the pitch centre distance. …
4. Step 4: Measure the centre of the driven gear from the centre of the driver gear.
