What is the function of sprocket?
Sprockets are used in bicycles, motorcycles, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc.
What sprocket means?
1 : a toothed wheel whose teeth engage the links of a chain. 2 : a cylinder with teeth around the circumference at either end that project through perforations in something (such as motion-picture film) to move it through a mechanism (such as a projector)
What is a sprocket in engineering?
sprocket in Mechanical Engineering A sprocket is a fairly thin wheel with teeth projecting outwards from the rim, especially a wheel that drives or is driven by a chain.
What is a sprocket on a dirt bike?
A major component of the drive, dirt bike sprockets hold the chain and together propel your bike. Sometimes though you need a replacement sprocket but many riders looking for more top end or bottom end can replace an existing sprocket with one that has more or less teeth for the desired outcome. …
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.
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. For taller gearing, a one-tooth-larger countershaft sprocket is often the best bet.
What causes sprocket wear?
Wear on the sides of sprocket teeth generally indicates improper installation of sprockets and/or shafts. If the shafts are out of parallel or not in the same plane, non-symmetrical wear will appear on sprockets or chain rollers. MAINTENANCE: After proper alignment is made, re-tighten set screws in sprocket hubs.
How do you calculate sprocket speed?
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 many teeth should a BMX sprocket have?
Many different sizes of Sprocket exist so its important you know which one to get. Predominantly most popular is 25 Tooth, to maintain a traditional gearing this would mean running a 9 tooth rear cassette or driver.
Why do BMX have small sprockets?
Small Sprocket Advantages Small sprockets are also easier to keep from contacting inert objects while tricks are being performed and generally experience less damage than larger sprockets when performing stunts.
Does BMX stand for something?

What is the smallest sprocket for BMX?
Micro drive is a type of bicycle drivetrain, mostly BMX and MTB, that uses smaller than standard-sized sprockets. The smallest rear sprocket that fits on a freehub body is an 11-tooth, but with the use of a cassette hub, sometimes called a micro drive rear hub, sprockets as small as 8 teeth may be used.
How do I know what size sprocket I need?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
Will 40 chain fit 420 sprocket?
They are the same pitch (1/2″) but 420 is narrower used primarily on the thin, lightweight kart sprockets. 40 chain will run on a 420 sprocket but I think it will have way too much side to side play.
