The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the present invention mainly is made up of cylinder 3, active fork 4, rotating shaft 5, fork transmission mechanism and blanket cylinder 13, wherein, the fork transmission mechanism is made up of fork 6, rod assembly 7, fork gear 8, sector gear 10, and rod assembly 7 is made up of first oscillating bearing 17, pull bar 16 and second joint bearing 15.
As shown in Figure 1, the tail end of cylinder 3 is installed on the front wallboard 1 by cylinder installation shaft 2 and screw, and the tailpiece of the piston rod of cylinder 3 is by bearing pin hinge active fork 4; Initiatively the other end of fork 4 is fixed in the rotating shaft 5; Described rotating shaft 5 is installed on front wallboard 1 and the rear wall plate 14 by bearing 19, and bearing 19 adopts the tight fit mode to be installed in the rotating shaft 5, and bearing 19 is inboard by internal bearing sleeve 21 location, and bearing 19 outsides are fixing by spacer ring 20, back-up ring 18; The fork transmission mechanism is two groups, be installed in rotating shaft 5 two ends of front wallboard 1, rear wall plate 14 inboards respectively, fork 6 is fixed in the rotating shaft 5 by screw and key 22, the other end of fork 6 is by bearing pin first oscillating bearing 17 that is hinged, first oscillating bearing 17 connects second joint bearing 15 by pull bar 16, second joint bearing 15 is by bearing pin hinge fork gear 8, and fork gear 8 is installed on front wallboard 1, the rear wall plate 14 by gear installation shaft 9; Described blanket cylinder 13 is installed on front wallboard 1 and the rear wall plate 14 by eccentric bushing 12 and bearing assembly 11, be separately installed with sector gear 10 on the axle journal at blanket cylinder 13 two ends, sector gear 10 is meshed with fork gear 8 in described two fork transmission mechanisms respectively.
The course of work of the present invention is as follows:
When the piston rod of cylinder 3 stretches out, promote initiatively fork 4 displacements, initiatively fork 4 drives rotating shaft 5 rotations, the fork 6 that is fixed in the rotating shaft 5 moves along with the rotation of rotating shaft 5, fork 6 drives fork gear 8 by rod assembly 7 and rotates around gear installation shaft 9, fork gear 8 drives sector gear 10 rotations with its engagement when rotating, and then drive blanket cylinder 13 rotates, because blanket cylinder 13 adopts eccentric bushing 12 to be installed on front wallboard 1 and the rear wall plate 14, blanket cylinder 13 rotates has realized that promptly clutch presses work.
Because rotating shaft 5 adopts bearing 19 to be installed on front wallboard 1 and the rear wall plate 14, changed friction type, promptly be converted into rolling friction by sliding friction, reduce coefficient of friction, the loss of energy between the friction of rotating shaft 5 and front wallboard 1, rear wall plate 14 reduces greatly, the transmission efficiency of whole machinery improves greatly, and lubricant effect is better.
