? Type of input power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of equipment to be driven.
? Amount of horsepower demanded to provide suffi cient power to your driven shaft.
? Full load velocity with the fastest working shaft (rpm).
? Desired pace on the slow working shaft ( or even the demanded pace ratio). NOTE: If speeds are variable ascertain the horsepower to be transmitted at just about every velocity.
? Diameters with the drive and Roller%20chain%20Cottered%20Chaindriven shafts . . . This value may restrict the minimal amount of teeth for your sprockets.
? Center distance on the shafts.
? Note the position and any room limitations that could exist. Usually these limitations are within the highest diameter of sprockets (this restricts using single strand chains) or even the width with the chain (this restricts the usage of multi-strand chains).
? Conditions on the drive including a determination in the class of load (uniform, reasonable or hefty), serious operating temperatures or chemically aggressive environments ought to be noted.
