<p>The invention proposes an eccentrical motion mechanism which uses a bearing to afford a change a rotary motion into advance motion. The invention can be characterised in that a cam (5) mounted to a driving shaft (3) is fixed into an inner ring of the bearing (4). An outer ring of said bearing (4) executes a sinusoidal movement, whilst rolling friction in the bearing is made use of.</p> |
