I am attempting to design a basic 3 axis system, where the motor to idler ratio is 3:1, and the idler to driven ratio is 1:2. The motor is 1.5 kW, variable speed. All three axis are in vertical alignment. This is a belt drive using a flat multi-vee belt.
My problem is trying to explain the difference between the static and dynamic loads on the shafts. I have been told that centrifugal force plays a part in the lower dynamic loads, but I am still not able to understand this to a point where I can pass along the information. The motor will rotate anywhere from 150 to 10000 RPM - how does such a low speed generate enough centrifugal force to change the shaft load?
Can anyone pass on some basic theory or point me to some sites where I can read up on this?
Thanks for the help
