simpel vibration simulation

hi there i am trying to make a simple vibration model. the point of the model is to visualize vibrations with imbalance. so i modeled a axis and 2 sleeve bearings. with exaggerated tolerance. i want to simulate the rotation of the axis with the influence of gravity. i am new to dynamic simulations. my first problem is that i cannot define the direction of the gravity. please help. see attached file
