Abstract
A drive mechanism is provided for a printing unit. The printing unit has an axially movable forme cylinder and a second cylinder that cooperates with the forme cylinder. The forme cylinder can be driven by a drive motor through a spur tooth gear. The second cylinder is driven by the forme cylinder through a drive connection between the two.
Claims43
A drive mechanism for a printing unit comprising:
- a forme cylinder having a journal and being supported for rotation about an axis of rotation and shiftable in an axial direction through an axial distance;
- a transfer cylinder acting with said forme cylinder and having a journal;
- a common drive motor for said forme cylinder and said transfer cylinder;
- a first gear drive between said common drive motor and said forme cylinder, said first gear drive being at least partially a spur gear drive;
- and
- a positive drive connection between said forme cylinder and said transfer cylinder, wherein power is transferred from said common drive motor to said forme cylinder through said first gear drive and from said forme cylinder to said transfer cylinder through said positive drive connection, said positive drive connection including at least one pair of cooperating spur-toothed members which are movable relative to each other in said axial direction.
