Hi,
Im new to the forum and also fairly new to Pro/Mechanica. I have searched the forum and already found some useful tips but am still struggling with a particular problem.
Basically I am trying to run some FEA on a shaft and gear assembly. The shaft will be supported in radial bearings and the gear will be mounted in the centre of the bearings and keyed to the shaft. The problem I am having is with constraining the points where the shaft will be mounted in the bearings. I want to constrain the the shaft to prevent translation in the y and z directions but still allow the shaft to rotate. I have tried constraing the surfaces where the bearings will be placed but as soon as I fix the shaft for translation it can no longer rotate dispite allowing rotation.
If anyone could offer some advise on how best to apply constraints that would simulate mounting the shaft in bearings it would be much appreciated.
