Abstract
A housing including an internal gear having a first central axis as a center; a first rotating body relatively rotatably joined to the housing; a second rotating body including an external gear having a second central axis parallel to the first central axis as a center and meshing with an internal gear and relatively rotatably joined to the first rotating body; a ram shaft joining part connected to the second rotating body and configured to be linearly moved in a reciprocating manner in a prescribed direction; and an air supply path passing through the insides of the first rotating body, the second rotating body, and the ram shaft joining part are provided.

A reciprocating linear motion mechanism for a can body maker, comprising:
- a housing including an internal gear having a first central axis as a center;
- a first rotating body located inside the housing and relatively rotatably joined to the housing;
- a second rotating body including an external gear having a second central axis parallel to the first central axis as a center and meshing with the internal gear and relatively rotatably joined to the first rotating body;
- a ram shaft joining part connected to the second rotating body and configured to be linearly moved in a reciprocating manner in a prescribed direction;
- and
- an air supply path passing through insides of the first rotating body, the second rotating body, and the ram shaft joining part, wherein
- the air supply path includes an air chamber that is arranged in the first rotating body and configured to store air therein, said air chamber being coaxially aligned with the first central axis.
A reciprocating linear motion mechanism of a can body maker, comprising:
- a housing including an internal gear having a first central axis as a center;
- a first rotating body located inside the housing and relatively rotatably joined to the housing;
- a second rotating body including an external gear having a second central axis parallel to the first central axis as a center and meshing with the internal gear and relatively rotatably joined to the first rotating body;
- a ram shaft joining part connected to the second rotating body, having a third central axis parallel to the second central axis as a center, and being linearly moved in a reciprocating manner in a prescribed direction while rotating around the third central axis;
- a valve part connected to the ram shaft joining part;
- and
- an air supply path passing through insides of the first rotating body, the second rotating body, the ram shaft joining part, and the valve part,
- wherein the valve part has a flow mode in which air is able to pass therein and a cutoff mode in which air is unable to pass therein switched between in accordance with a rotation position around the third central axis of the ram shaft joining part.
