Stress Analysis of Pulley
Stress Analysis of Pulley
(OP)
What loads are needed, how should they be applied, and what is the proper approach to use to analyze a pulley? I have a solid model of the pulley and I'm trying to determine if plastic would be appropriate. I've been given the applied torque, hub load, and rpm. I also have the operating temperature. Thanks.

There will be a tension, T1 on the slack side of the pulley and a tension, T2 on the tight side of the pulley.
Now the driving force on the pulley, Fce = T2-T1 and the torque on the pulley Trq = Fce x radius of pulley. The resultant pull on the pulley (trying to bend the shaft), assuming T2 is parallel to T1, Pull = T2+T1. If T2 and T1 are not parallel to each other, then take their horizontal and vertical components to find the resultant force on the pulley shaft.
Hope this helps,
