Abstract
The utility model relates to a drive apparatus without shaft of the web offset machine, which comprises a rubber roller (2), a rubber roller gear (3), a form roller (1), a form roller gear (4), the rubber roller gear and the form roller gear are in mesh, the utility model also comprises a servo motor (6) and a reducing gear (7), an output shaft of the servo motor is connected with the reducing gear, the reducing gear and the form roller gear are in mesh. The utility model has the advantages that the apparatus increases the adjustment precision of the roller when transmission without shaft, the power transfer calmly, fixing expediently, no need to adjust the position of the motor, increasing the precision of the print socket of the printer.
Description
Technical field
The utility model relates to the no axial brake device of roll-fed offset printing press.
Technical background
The no axial brake device of existing roll-fed offset printing press adopts motor to drive rubber cylinder by gear train and cog belt and is loaded on the rubber cylinder gear of rubber cylinder spindle nose, drives plate cylinder gear and plate cylinder through gears engaged.Because rubber cylinder in press must make frequent clutch action, easily cause the distortion of cog belt and influence the rubber cylinder change in location and cause degree of regulation to reduce; And because the yielding elongation of cog belt, thereby need often to adjust the motor installation site, cause operational difficulty.
Summary of the invention
The utility model has overcome existing no axial brake device influences the defective that the cylinder position variation causes the degree of regulation reduction, needs often to adjust the motor installation site owing to adopt cog belt to drive, a kind of no axial brake device of roll-fed offset printing press is provided, the adjustment precision of cylinder when this no axial brake device has improved no through-drive, transmission of power is steady, easy for installation, need not to adjust motor position, improved the press printing alignment precision.
The utility model is achieved in that a kind of no axial brake device of roll-fed offset printing press, comprise rubber cylinder, rubber cylinder gear, plate cylinder, plate cylinder gear, servomotor and reduction gearing, rubber cylinder gear and plate cylinder gear engagement, the servomotor output shaft connects reduction gearing, reduction gearing and plate cylinder gear engagement.
In the no axial brake device of above-mentioned roll-fed offset printing press, describedly between servomotor and reduction gearing, shaft coupling is housed, the servomotor output shaft coupling that is coupling, the reduction gearing axle also connects shaft coupling and concentric with the servomotor output shaft.
In the no axial brake device of above-mentioned roll-fed offset printing press, described shaft coupling is no backlash yielding coupling.
The utility model adopts servomotor to drive plate cylinder by yielding coupling and drives rubber cylinder again, and rubber cylinder drives as the back one-level, and the shift in position influence that rubber cylinder is produced by clutch action is reduced to minimum; No backlash yielding coupling is installed between servomotor and reduction gearing, is kept elastic prestress, solved impact and the wearing and tearing of motor between the busy shift middle gear, reach the steady transmission of power of no backlash.The adjustment precision of cylinder when this device has improved no through-drive, transmission of power is steady, and is easy for installation, need not to adjust motor position, improved the press printing alignment precision.
Description of drawings
Fig. 1 is the no axial brake device structural representation of the utility model roll-fed offset printing press.
Among the figure: 1 plate cylinder, 2 rubber cylinders, 3 rubber cylinder gears, 4 plate cylinder gear, 5 no backlash yielding couplings, 6 servomotors, 7 reduction gearing, 8 frames.
The specific embodiment
Referring to Fig. 1, a kind of no axial brake device of roll-fed offset printing press, comprise rubber cylinder 2, rubber cylinder gear 3, plate cylinder 1, plate cylinder gear 4, servomotor 6 and reduction gearing 7, rubber cylinder gear 3 and plate cylinder gear 4 engagements, 7 of servomotor 6 and reduction gearing are equipped with no backlash yielding coupling 5, servomotor 6 is exported the anodontia crack yielding coupling 5 that is coupling, 7 of reduction gearing also connect yielding coupling 5 and concentric with servomotor 6 output shafts, reduction gearing 7 and plate cylinder gear 4 engagements.Servomotor 6 is installed on the frame 8, and 7 of reduction gearing are installed on the frame 8.2 of rubber cylinders and 1 of plate cylinder also are installed on the frame 8.There is the certain precision requirement in the hole that plate cylinder 1 and reduction gearing 7 are installed, and the centre bore that 6 of servomotors are installed also has required precision, and 7 of servomotor 6 output shafts and reduction gearing connect by shaft coupling 5 and keep concentric during assembling.This sample does not have axial brake device and drives reduction gearing 7 driving plate cylinder 1 earlier by motor 6, drives rubber cylinder 2 again through gears engaged, has improved plate cylinder 1 positional precision, adopt meshed transmission gear, the driving force transmission is steady, and easy for installation, has improved the press printing alignment precision.
