Abnormal stress in rotating element

[kngstn]

Hi.

I am trying to model analysis of harmonic drive in Abaqus 6.31-1. I am recieving, in my opinion, abnormal stresses in rotating wave generator. I'm beginer in Abaqus, so it might be my mistake, of which i'm not conscious. Could someone have a look and suggest me something? Also I don't know how to model torque instead of angular velocity, which I have already applied, so I can't check stresses in the teeth of the gears.

The rotation in the last step is applied with the default amplitude. I guess that's the reason for the problem.

So how should I make it?

Also I have problem with applying torque, nothing happens. Coupling interaction should be done differently?
