(10) Since the projection protrudes outward, the operation shaft (54a) is rotated clockwise or counterclockwise by holding the operation rod (57) by hand.
- the eccentric shaft portion (54b) of the eccentric shaft member (54) moves in an arc shape around the central axis of the operation shaft portion (54a), so that both the spline members (23) and (24) are in the circumferential direction. Move to.
- the spline teeth (23a) and (24a) of both spline members (23) and (24) are pressed against both side walls of the spline groove (13) of the connecting shaft (5a) with an appropriate force, and backlash between them is eliminated. Then, the eccentric shaft member (54) is fixed at that position.
- Printing can be performed after the above rough registration has been completed, but by moving the position adjustment member (11) in the front-rear direction and moving the gear member (7) in the front-rear direction, fine registration is possible. Can do.
- the gear member (7) moves in the front-rear direction
- the second gear (6) moves in the front-rear direction with respect to the first gear (1), and the teeth of the first gear (1) and the second gear (6) ( The first gear (1) and the second gear (6) rotate relatively by the twist angle of 1a) and (6a).
- the rotational phases of the first gear (1) and the plate cylinder drive shaft (5) change, and fine registration is possible.
- the rotation of the first gear (1) is rotated via the second gear (6) and the gear member (7) and the rotation preventing member (9) are fixed to the gear member (7) as described above. It is transmitted to the plate cylinder drive shaft (5), and the plate cylinder (2) rotates.
- the second spring (46) urges the third gear (8) to rotate in the rotational direction with respect to the second gear (6). No backlash occurs between the third gears (6) and (8). Further, since the first spring (44) urges the third gear (8) toward the second gear (8) and presses it against one side of the second gear (6), the third gear (8) It does not tilt.
- oil is supplied to the inside of the gear member (7) from the two types of oil supply holes (21) and (22) of the gear member (7).
- the oil supplied from the first oil supply hole (21) enters the annular groove (15) of the boss part (14), and the sliding parts (14a) (14b) before and after the groove (15) and the connecting shaft part (5a )
- the oil supplied from the second oil supply hole (22) enters the gap between the sliding part (14b) on the rear side of the annular groove (15) and the connecting shaft part (5a). For this reason, a thin oil film is formed between the inner peripheral surface of the sliding portion (14a) (14b) of the boss portion (14) and the outer peripheral surface of the connecting shaft portion (5a), thereby the gear for the drive shaft (5).
- the member (7) is centered.
- the configurations of the printing press and the plate cylinder driving device (3) are not limited to those of the above-described embodiments, and can be changed as appropriate.
- the present invention is suitable for use in a plate cylinder driving device in a printing press.
- it is suitable for use in a plate cylinder driving device in a printing machine that performs multicolor printing on the outer peripheral surface of a beverage can.
- the plate cylinder driving device according to the present invention it is possible to eliminate the backlash of the helical gear on the driving side and the helical gear on the driven side, smooth the rotation of the driven gear member, and improve the rotation accuracy of the plate cylinder. This can improve the quality of printing.
