Depends on where you are and what you are riding.

BMXes usually call it a driver at the back and a sprocket at the front.

Other bikes use different names.

At the rear, if it's only one, it's either a single speed freewheel, or a sprocket.

If it's more than one it's either a cassette or a multi-speed freewheel.

At the front it's called chain wheels or chain rings.

How does a bicycle designer use math?

A bicycle designer uses maths to work out the frame angles, and the gearing. The number of teeth on the chainwheels, sprockets (cassette), chain length, and so on, all depend on maths.

What do you call those metal things for braces?

brackets? (square/circle things glued to teeth) wire? (self explanatory)

What is a good title for a science fair board about teeth?

What is sprocket?

It's the small toothed wheel that the chain runs over by the rear wheel, although in engineering terms it is any toothed wheel designed for a chain, including the one rotated by the pedal and crank on a bicycle.

What is the smallest sprocket?

The smallest sprocket is usually referred to as the "cog" and is commonly found on the rear wheel of a bicycle. It is designed to mesh with the chain and is typically the one with the fewest number of teeth among all the sprockets on the bike.

What are the causes of bike chain slip?

Usually what happens is that the chain elongates under wear, which forces the rollers farther apart. Depending on set-up this can then cause the chain to ride higher up on the teeth of the sprocket, eventually to the point where it can jump over the top of the teeth. On other set-ups the elongated chain will wear out the flanks of the teeth to the point where their angle can no longer retain the chain.

Which way should the teeth on a chainsaw face?

A chainsaw's chain should be fitted so that the points of the teeth face in the same direction as the chain moves. Then they will cut into the wood without needing much downward pressure. If the teeth are sharp you should never have to force the chain down into the surface of the wood. If you find you have to force the chain down to make it cut the wood then the teeth must either have gone blunt - and the chain needs to be sharpened or replaced - or the chain was installed with the teeth facing the wrong way so that the backs of the teeth just rub over the surface of the wood and you need to press down very hard just to get the teeth to wear down into the wood instead of cutting it cleanly.

How does a bike chain stay on the sprocket?

The chainring by the pedals and the sprocket(s) by the rear wheel.

How do you calculate face width per gear?

Its is taken standard as 2*pitch circle diameter - 3**pitch circle diameter for cast teeth. 3 *pitch circle diameter - 4 *pitch circle diameter for cut teeth. Pitch circle diameter = PI*module regards, Pranav
