Chain Drive:- Types of Chains  Hoisting Chains  Conveyor Chains  Power transmission Chains. Relation between Pitch and Pitch circle diameter, Length of chain

A chain drive is used for reduction of s peed from 240r.p.m. to 120r.p.m. The number of teeth on the driving s procket is 20. Find the number of teeth on the driven s procket. If the pitch circle diameter of the driven s procket is 600mm and centre to centre distance between the two sprocket is 800mm, determine the pitch and length of the chain.
