What is sprocket in chain?
A sprocket, sprocket-wheel or chainwheel is a profiled wheel with teeth that mesh with a chain, track or other perforated or indented material. The name ‘sprocket’ applies generally to any wheel upon which radial projections engage a chain passing over it.
What is the pitch diameter of a sprocket?
The sprocket pitch diameter is an imaginary circle through which the chain pin centers move around the sprocket. The pitch diameter is the fundamental design geometry that determines the size shape and form of the sprocket teeth dimensions.
How is a sprocket calculated?
Calculating the Sprocket Ratio The sprocket ratio is simply the number of teeth on the driving sprocket (T1) divided by the number of teeth on the driven sprocket (T2). If the front sprocket on a bicycle has 20 teeth and the rear sprocket has 80, the sprocket ratio is 20/80 = 1/4 = 1:4 or simply 4.
Why are sprocket used?
They’re regularly used on bicycles to pull a linked chain to turn the movement of the rider’s feet into rotation of the bike’s wheels. Sprockets are also used on tracked vehicles such as tanks and farming machinery. They line up with the links of a track and pull them as it rotates, allowing the vehicle to move.
How many types of sprockets are there?
Type A sprockets, which are only the plate with no added thickness or hubs. Type B sprockets, which have a hub on one side. Type C sprockets, which have hubs of equal thickness on both sides of the plate.
How do you size a sprocket?
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.
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 sprocket type?
Sprockets are classified into four types but the most commonly used sprockets are: Chain sprockets, Duplex sprockets, Industrial sprockets, Drive sprockets, Triplex sprockets, Shaft sprockets, Simplex sprockets, Single pitch and double pitch sprocket, Drum sprockets.
How do you read a sprocket?
The sprocket size represents the first two digits in the chain designation. Example: 40A14 is size 40. The number of teeth represents the last two digits in the chain designation. Count the number of teeth.
What is a sprocket ratio?
The sprocket ratio is simply the number of teeth on the driving sprocket (T1) divided by the number of teeth on the driven sprocket (T2).
