Title:
PLATE CYLINDER DRIVE DEVICE IN PRINTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/111091
Kind Code:
A1
Abstract:
A backlash of a driving side helical gear and a driven side helical gear is eliminated, and a rotation of a driven side gear member is smoothed, to increase rotation accuracy of a plate cylinder.
A plate cylinder driving device (3) is provided with a plate cylinder driving shaft (5), the driven side gear member (7) which has the driven side helical gear (6) engaged with the driving side helical gear (1) and is attached around the plate cylinder driving shaft (5), a position adjustment member (11) which causes the driven side gear member (7) to move to be fixed to a predetermined position, a baffle member (9) attached to the plate cylinder driving shaft (5), a nipping member (10) which fixes the baffle member (9) to the driven side gear member (7) so as to be attachable and detachable, a backlash removal helical gear (8) disposed on one side of the driven side helical gear (6), a first spring (44) which causes the backlash removal helical gear (8) to be press-contacted to the driven side helical gear (6), and a second spring (46) which biases the backlash removal helical gear (8) so as to rotate in a predetermined direction.
