Sprockets By Span Engineers

There are four types of sprocket;
Type A: Plain Plate sprockets
Type B: Hub on one side
Type C: Hub on both sides
Type D: Detachable hub

Span Engineers can make all 4 type of Sprockets
Sprockets should be as large as possible given the application. The larger a sprocket is, the less the working load for a given amount of transmitted power, allowing the use of a smaller-pitch chain. However, chain speeds should be kept under 1200 feet per minute.

The dimensions of a sprocket can be calculated as follows, where P is the pitch of the chain, and N is the number of teeth on the sprocket;
Pitch Diameter = P A. sin (180A A. N)
Outside Diameter = P A (0.6 + cot ( 180A A. N) )
Sprocket thickness = 0.93 A Roller Width - 0.006"
