DRIVE SPROCKET
What is a Drive Sprocket
Sprockets are rotating parts with teeth that are used in conjunction with a chain to transmit powerIn order for sprockets and chain to be compatible with each other they must both have the same thickness and pitch. In order for the sprockets and chain to work effectively, all of the sprockets should be on parallel shafts with their corresponding teeth on the same plane.
Parts of a Sprocket
Number of Teeth – The total number of teeth (projections) around the whole circumference of a sprocketPitch Diameter (PD) – An imaginary circle which is traced by the center of the chain pins when the sprocket rotates while meshed with a chainPitch – The amount of pitch diameter in inches per tooth. Gears with a larger pitch will have bigger teeth
When to Replace
Check how well the chain meshes with the sprocket teeth. In a healthy chain and sprocket combo, the individual chain rollers align perfectly with the spaces between the sprocket teeth and fit down into those U-shaped grooves evenlyLook closely at the sprocket teeth to see if they have become sharp at the tips and/or slightly curled. The teeth on a new sprocket are straight and have a flat or domed shape at the tip, If the teeth are sharp, the sprocket is worn
