| Summary: | The drive housing of a bodymaker carries a major ring in stationary position and a planetary ring carrier for rotation on the central axis of the major ring. The planetary ring carrier carries a minor planetary ring in internal engagement with the major ring for rotation on its own axis in rolling orbit against the inside circumference of the major ring. A crank is connected to rotate with the planetary ring and provides a journal positioned at the circumference of the planetary ring for drivingly engaging a ram. The diameter of the planetary ring is one-half the diameter of the major ring, establishing a straight-line path of movement for the journal along an axis (X-X) parallel to a selected diameter of the major ring. A frame supports ram in suitable position with respect to drive housing for straight-line reciprocation on the axis (X-X) parallel to the selected diameter. A second ram may extend in the opposite direction from the crank pin on a same or parallel axis (X-X) to establish a double-action bodymaker. |
