Description
Technical field
The present invention relates to a kind of printing press, especially the mechanical seal device in a kind of pneumatic jack unwinding and rewinding mechanism on the printing press.
Background technique
Pneumatic jack unwinding and rewinding mechanism is that printing press, coating machine etc. relate to one of mechanism indispensable on the machine that adopts web at present.Pneumatic jack unwinding and rewinding mechanism comprises revoliving arm at present; Said revoliving arm is provided with cylinder and main shaft, and the inwall of revoliving arm also is provided with mechanical seal device, and mechanical seal device comprises that being used for revoliving arm rotates the radially geared sleeve axial gears cover flexible with being useful on main shaft; Main shaft is connected with cylinder through mechanical seal device; So once be used and not only wasted cost, also damage easily, repair comparatively trouble with two geared sleeves.
Summary of the invention
The present invention is high, fragile in order to solve present mechanical seal device cost, and the problem of maintenance trouble provides the mechanical seal device in a kind of pneumatic jack unwinding and rewinding mechanism.
In order to achieve the above object; The solution that the present invention takes is: the mechanical seal device in a kind of pneumatic jack unwinding and rewinding mechanism comprises axle sleeve; But an end of axle sleeve is provided with the gear bush of sleeve type, is provided with tension device between said gear bush and the axle sleeve, and said tension device comprises first fixed base and second fixed base; Said first fixed base is fixed in the axle sleeve; Second fixed base is fixed in the gear bush, and being provided with between said first fixed base and second fixed base can be for gear bush flexible spring in axle sleeve, and an end of spring is provided with the spring seat that is used for fixing spring; Fit tightly above the bottom surface of spring seat and first fixed base, the spring the other end and second fixed base flexibly connect.
Technological scheme according to the present invention is said, is provided with the bayonet socket of fixing first fixed base in the axle sleeve.
Technological scheme according to the present invention is said, is provided with the screw that is used for fixing second fixed base in the gear bush.
Technological scheme according to the present invention is said, is provided with seal ring between first fixed base and the spring seat.
Technological scheme according to the present invention is said, and axle sleeve is provided with the tank filler sleeve of the time institute's lubricating oil filling that can slide for gear bush.
The invention has the beneficial effects as follows: cost is low, and is not fragile, easy to maintenance.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a topology view of the present invention;
Fig. 2 is a whole-cutaway view of the present invention.
Reference character is among the figure: 1 is axle sleeve, and 2 is gear bush, and 3 is first fixed base, and 4 is second fixed base, and 5 is spring, and 6 is spring seat, and 7 is bayonet socket, and 8 is screw, and 9 is axle.
Embodiment
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
Referring to the mechanical seal device in Fig. 1, the shown in Figure 2 a kind of pneumatic jack unwinding and rewinding mechanism; Comprise axle sleeve 1, but an end of said axle sleeve 1 is provided with the gear bush 2 of sleeve type, is provided with tension device between gear bush 2 and the axle sleeve 1; Said tension device comprises first fixed base 3 and second fixed base 4; Said first fixed base 3 is fixed in the axle sleeve 1, and second fixed base 4 is fixed in the gear bush 2, is provided with spring 5 between said first fixed base 3 and second fixed base 4; One end of spring 5 is provided with the spring seat 6 that is used for fixing spring; Fit tightly above the bottom surface of spring seat 6 and first fixed base 3, spring 5 the other ends are connected with second fixed base movable 4, are provided with the bayonet socket 7 of fixing first fixed base 3 in the axle sleeve 1.Be provided with the screw 8 that is used for fixing second fixed base 4 in the gear bush 2.Be provided with seal ring between first fixed base 3 and the spring seat 6, axle sleeve 1 is provided with tank filler sleeve.Earlier axle sleeve being gone into gear bush during use is enclosed within on the axle 9; Order assembles tension device and is installed in gear bush then; To load onto axle sleeve at last, the end with axle is connected with cylinder at last, and the mechanical seal device in the pneumatic jack unwinding and rewinding mechanism just can realize that cost is low like this; Not fragile, easy to maintenance.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
