Summary: | The drive housing ( 26 ) of a bodymaker ( 20 ) carries a major ring ( 32 ) in stationary position and a planetary ring carrier ( 36, 46 ) for rotation on the central axis of the major ring. The planetary ring carrier ( 36, 46 ) carries a minor planetary ring ( 34 ) in internal engagement with the major ring ( 32 ) for rotation on its own axis in rolling orbit against the inside circumference of the major ring ( 32 ). A crank ( 54 ) is connected to rotate with the planetary ring and provides a journal ( 56 ) positioned at the circumference of the planetary ring ( 34 ) for drivingly engaging a ram ( 60 ). The diameter of the planetary ring ( 34 ) is one-half the diameter of the major ring ( 32 ), establishing a straight-line path of movement for the journal ( 56 ) along an axis (X-X) parallel to a selected diameter of the major ring ( 32 ). A frame ( 22, 72 ) supports ram ( 60 ) in suitable position with respect to drive housing ( 26 ) for straight-line reciprocation on the axis (X-X) parallel to the selected diameter. A second ram ( 66 ) may extend in the opposite direction from the crank pin ( 56 ) on a same or parallel axis (X-X) to establish a double-action bodymaker ( 20 ). |
