Abstract
A driving mechanism for a cylinder of a rotary printing machine utilizes a drive pinion that engages a drive gear of a cylinder which is supported in an eccentric bushing. The cylinder can be moved between print and non-print positions. The rotational axis of the drive pinion lies on a straight line defined by the axis of rotation of the cylinder and the axis of rotation of the eccentric bushing.
Claims28
A driving mechanism for cylinders of a rotary printing press comprising:
- an eccentric bushing supported for rotation and having a bushing bore and a bushing pivot axis;
- a transfer cylinder having a cylinder journal supported for rotation in said bushing bore and having a cylinder journal axis of rotation;
- a drive wheel supported on said cylinder journal and useable to rotate the cylinder;
- a drive pinion engagable with said drive wheel and having a drive pinion axis of rotation;
- a first straight line defined by said drive pinion axis of rotation and said bushing pivot axis;
- a second straight line defined by said bushing pivot axis and said cylinder journal axis of rotation, said first and said second straight lines intersecting and defining a first opening angle in the ranges between −20° and +20°′;
- a printing cylinder supported for rotation and having a printing cylinder axis of rotation;
- and
- a third line defined by said printing cylinder axis of rotation and said drive pinion axis of rotation, said third line intersecting said first line at a second opening angle in the range between 160° and 200°, said transfer cylinder and said printing cylinder directly contacting each other and forming a pair of cylinders.
A driving mechanism for cylinders of a rotary printing press comprising:
- an eccentric bushing supported for rotation and having a bushing bore and a bushing pivot axis;
- a first cylinder including a cylinder journal supported in said bushing bore and rotatable about a cylinder journal axis of rotation;
- a first drive wheel supported on said cylinder journal;
- a drive pinion engageable with said first drive wheel and having a drive pinion axis of rotation;
- a first straight line defined by said drive pinion axis of rotation and said bushing pivot axis;
- a second straight line defined by said bushing pivot axis and said cylinder journal axis of rotation, said first and second straight lines intersecting at a first opening angle in the range of between +20° and −20°;
- a second drive wheel supported coaxially with said first drive wheel;
- and
- a second cylinder having a third drive wheel, said second drive wheel being in engagement with said third drive wheel and having a second cylinder axis of rotation.
A driving mechanism for a cylinder of a rotary printing press comprising:
- an eccentric bushing supported for rotation and having a bushing bore and a bushing pivot axis;
- a cylinder journal of the cylinder, said cylinder journal supported for rotation in said bushing bore and rotatable about a cylinder journal axis of rotation;
- a drive wheel supported on said cylinder journal;
- a drive pinion engageable with said drive wheel and having a drive pinion axis of rotation;
- a drive motor having a rotor, said drive pinion being directly connected with said rotor;
- a first straight line defined by said drive pinion axis of rotation and said bushing pivot axis;
- and
- a second straight line defined by said bushing pivot axis and said cylinder journal axis of rotation, said first and second straight lines intersecting at a first opening angle in the range of between +20° and −20°.
