The Classification Of Sprockets

The Classification Of Sprockets

Summary

These are the most common types of sprockets used .

They work only with chains designed by rollers interconnected by pins .

Roller chains provide a gap that the fits the teeth of the sprocket to transfer totary motion .

The Classification Of Sprockets
The Classification Of Sprockets
Type A
This sprocket is flat and has no hub on it . These are typicallymounted on the flanges or hubs of the equipment .
They drive through a series of holes that are plain or thin .

Type B
This sprocket made with a hub on its one side . This allows the sprocket to fit closely to the machinery on which it is mounted .
It reduces a large overhang load on the bearings of the equipment .
Type C
These sprockets are amde with a hub on its both side of plate .
It is typically used in such applications where the pitch diameter is large and there is more weight to suppor on the shaft . 
Large loads require bigger hubs

Chain Sprockets
These are the most common types of sprockets used .
They work only with chains designed by rollers interconnected by pins .
Roller chains provide a gap that the fits the teeth of the sprocket to transfer totary motion .
They are used in transmissions equipment application 
Duplex Sprocket
The duplex sprockets are usually made of mild steel and sometimes of stainless stell in many different sizes .
It mainly consists of double-strand sprockets.
It is maybe of single hub or double hub as per the required specifications .
Triple Sprocket
It is constructed using high-quality mild steel and fabricated with high precision tolerances for optimum long-term performance .
These sprockets are consist of heat-treated hardened teeth that further improve the working and durability
Idler Sprocket
It is used where long lengths may cause chain slack , there is a non-adjustable drive shaft ,or the chain is guided around an obstacle .
The use of an idler sproxket stops chain whipping and uneven load distribution 
Taper Lock Sprocket 
This sprocket uses a split through the taper and flange to give a clamp on the shaft .
The taper-Lock bushing is held in place with the set screw on the sprocket
