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.
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. Type C offset or Type D sprockets, which also have two hubs.
What are the different types of sprockets?
Following are the main types of sprockets:
- Chain sprockets.
- Duplex sprockets.
- Industrial sprockets.
- Drive sprockets.
- Triplex sprockets.
- Shaft sprockets.
- Simplex sprockets.
- Single pitch and double pitch sprocket.
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.
Where are sprockets used?
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 are the parts of a sprocket?
Parts of a Sprocket Pitch Diameter: This is the circumference of the sprocket at the inner point between the teeth point where the chain meets the sprocket. Outside Diameter: The circumference around the sprocket at the end tips of the teeth. Pitch: The full measurement per tooth, usually represented in inches.
What is sprocket size?
A sprocket size ratio is the relationship between the number of teeth of two sprockets (input and output). In the image below, the input sprocket is a 15 tooth sprocket and the output is a 20 tooth. The sprocket size ratio for the example is 20T:15T.
What is the function of sprocket?
What is pitch in sprocket?
Pitch represents the amount of pitch diameter in inches per tooth. Sprockets with a larger pitch will have bigger teeth. Common pitches are 0.25”, known as #25, and 0.375” (#35).
What is pitch of 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.
Why are sprockets 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.
What is the sprocket modeling process?
This process provides a method for generating solid models of any standard sprocket, pitch, number of teeth, or configuration.
What is a type a sprocket?
These sprockets use a Type A sprocket mounted on a solid or split hub. The sprocket is easily splinted for removal and bolted to the hub. No need to remove bearings and other equipment because without it the speed ratio can be changed. Following are the main types of sprockets:
How do you write sprocket nomenclatures?
Sprocket nomenclatures provide the chain pitch written to the left of the hub style code letter followed by the number of teeth in the sprocket. If the sprocket is to be multiple strand, the prefix code letter is added to the beginning of the part number. A suffix of H is added if the teeth are to be heat treated.
What is sprocket selection e-160?
Sprocket Selection E-160 Application Data and Selection Procedure Design Horsepower When making drive selections consideration is given to the loads imposed on the chain. Service factors based on the type of equipment to be driven (Table I, Page E162) and the type of input power (Table II, Page E162) are used to compensate for these loads.
