How many teeth should be on sprocket?
Ideally sprockets should have a minimum of 19 teeth. For high-speed drives subjected to transient loads, the minimum number of teeth rises to 25.
How big is a 40 tooth sprocket?

| 40 | 3.327 | 4.990 |
| 41 | 3.406 | 5.109 |
| 42 | 3.486 | 5.229 |
Why odd number of teeth for sprocket is preferred?
It is preferable to use an odd number of teeth for the driving sprocket in combination with an even number of chain links for uniform wear and tear on the teeth and rollers. (In this case, a particular tooth of the sprocket wheel does not come in contact with a particular link of the chain for every rotation.)
How big is a 60 tooth sprocket?
Product Overview Inside Diameter: 1.1245 in. Thickness: 0.086-0.092 in.
What sprocket is best for speed?
For more top end and faster top speed, use a large countershaft/front sprocket or smaller rear sprocket. This creates a taller gearing ratio that’s best for high speed situations without many tight turns like wide open desert racing.
Is more teeth on a sprocket better?
Adding teeth to the front and rear sprockets have opposite effects. Installing a larger countershaft sprocket creates higher gearing, while a larger rear sprocket lowers gearing. Similarly, a smaller front sprocket lowers the gearing while a smaller rear sprocket makes the gearing higher.
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.
Where is a chain drive used?
Chain drives are employed for a wide range of power transmission applications, like in bicycles, motorcycles, rolling mills, agricultural machinery, machine tools, conveyors, coal cutters, etc. A chain drive consists of a chain and two wheels, called Sprockets.
What is the ANSI standard for chains and sprockets?
Because of this widespread usage, certain international standards are set to ensure that pitch, width, and other key characteristics of chains and sprockets are standardized. In the United States, power transmission chains must meet ANSI B29. 1, thus earning the name ANSI chains.
Does a bigger sprocket make you go faster?
A bigger rear sprocket/ smaller front sprocket will give you an increase in acceleration but decrease your top speed. A smaller rear sprocket/bigger front sprocket will reduce you acceleration but increase the top speed.
Which sprocket is faster?
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.
