Greetings everyone. The image you see below is a system we have been using for a garment conveyor. This system is designed rotate the conveyor chain with an mass of approximately 1500lbs. Now, the question is if I wanted to design a larger conveyor, it would require a larger conveyor chain thus, bigger chain mass, bigger diameter shaft and heavier duty roller chain motor hp and transmission hp. I would like to find out the starting torque to move a 2000lb or 2500lb chain and determine what shaft size is suitable for the conditions.
