Roller Chain Drive Design - Cross+Morse
CROSS+MORSER oller Chain by nature of its Design is capable of transmittinghigh torque loads, and provides the ideal Drive media for theconnection of slow to medium speed shafts located on extendedcentres. The selection and application is reasonably simple byfollowing normal engineering practices, but there are points ofgood Design practice specific to Roller Chain Drives, andconsideration of these will ensure successful Drive Design . Numbers of Teeth in SprocketsChordal Action:- As a Chain engages and disengages with asprocket there is a rise and fall of each link, and a velocityvariation. These are due to chordal action caused by thechain forming a polygon on the sprocket. In the diagramsbelow as Roller B approaches the sprocket it follows thechordal line of Roller A.
Roller Chain by nature of its design is capable of transmitting ... teeth, the value becoming insignificant on drives with 25 tooth sprockets or larger. Odd Numbers of Teeth:- As most drives have a chain with an ... A simple chain drive operates with an efficiency of 98%, therefore an allowance of 2%
