Description
Technical field
The utility model relates to a kind of printing machine to version adjusting device, particularly flexographic presses to version adjusting device.
Background technology
Current printing machine is undertaken regulating version by adding planetary gearsets to version adjusting device, and existing planetary gearsets comprises sun gear, planetary gear, planet carrier, gear ring and worm screw, sun gear is fixed on driving shaft, and planet carrier to be socketed on driven axle outer and fix with driven axle, sun gear and planetary gear engage each other, planetary gear is arranged on planet carrier, and the inner toothed surface engagement planetary gear of gear ring, the outer flank of tooth of gear ring and worm engaging, worm screw passes through driven by motor, when planetary gear carries out work, driving shaft drives planetary gear by sun gear, planetary gear is made to carry out revolving round the sun and rotation around sun gear, the rotation of the revolution band planet carrier of planetary gear, thus make driven axle rotation outputting power, when printing machine needs to carry out regulating version, first by driven by motor worm screw, then worm screw makes the rotation of gear driven gear ring, and the rotation and the revolution that drive planetary gear from the change of team of gear ring, the revolution of planetary gear can make planet carrier drive driven axle rotation outputting power, and in this process, driven axle rotates and driving shaft is static, reach the object that printing machine regulates version.Planetary gear is engaged in the inner toothed surface of sun gear and gear ring respectively, makes planetary gear easily because of the wearing and tearing of its rotation and revolution to lose efficacy, and the inner toothed surface process of gear ring is complicated and difficulty is comparatively large, the so also corresponding processing cost that improve gear ring.
Summary of the invention
In view of the deficiency of background technology, the utility model provide a kind of flexographic presses to the longer service life of version adjusting device, be convenient to processing, planetary gear not easily lost efficacy because of wearing and tearing.
The utility model adopts following scheme to solve: a kind of flexographic presses is to version adjusting device, comprise the driving shaft of band first sun gear, driven axle, multiple first planet and planet carrier, described the first row star-wheel and the first sun gear engage each other, it is characterized in that described planet carrier is socketed on driven axle, described driven axle is provided with the second sun gear, described the first row star-wheel is coaxially installed with the second planetary gear, described second sun gear engages with the second planetary gear, the rotating shaft of described the first row star-wheel and the second planetary gear is arranged on described planet carrier, described planet carrier is provided with external toothing, described external toothing and drive unit are in transmission connection.
On described driving shaft, cover is equipped with dust cap, and described dust cap and external toothing are fitted.
Described drive unit is worm screw, and described worm screw engages with described external toothing, and described worm screw is connected with power source.
Described drive unit is for being also gear, and described gear engages with external toothing, and described gear is connected with power source.
The advantage of the utility model contrast prior art is: flexographic presses drives planet carrier to carry out rotation to version adjusting device by the external toothing on planet carrier, thus make the second planetary gear carry out revolving round the sun and drive driven axle rotation, reach the object that flexographic presses carries out regulating version, deduct and driven planetary gear to revolve round the sun by the inner toothed surface of gear ring, reduce the difficulty of processing of gear ring, the first row star-wheel on planet carrier only engages with the first sun gear, reduce the wearing and tearing in its work, the longer service life of gear ring and planetary gear.

Detailed description of the invention
Embodiment 1: as Fig. 1, 2, shown in 3, a kind of flexographic presses that the utility model provides is to version adjusting device, comprise the driving shaft 2 of band first sun gear 1, driven axle 3, multiple the first row star-wheel 4 and planet carrier 5, described the first row star-wheel 4 and the first sun gear 1 engage each other, it is characterized in that described planet carrier 5 is socketed on driven axle 3, described driven axle 3 is provided with the second sun gear 7, described the first row star-wheel 4 is coaxially installed with the second planetary gear 8, described second sun gear 7 is taken turns with the second planet 8 and is engaged, the rotating shaft of described the first row star-wheel 4 and the second planetary gear 8 is arranged on described planet carrier 5, described planet carrier 5 is provided with external toothing 9, described external toothing 9 is in transmission connection with drive unit, wherein said drive unit is worm screw 6, described worm screw 6 engages with external toothing 9, and worm screw 6 is connected with power source, this power source is motor.Deducted and driven planetary gear to revolve round the sun by the inner toothed surface of gear ring, reduce the difficulty of processing of gear ring, the first row star-wheel 4 on planet carrier 5 only engages with the first sun gear 1, reduces the wearing and tearing in its work, the longer service life of gear ring and planetary gear.On described driving shaft 2, cover is equipped with dust cap 10, and described dust cap 10 is fitted with external toothing 9.In the cavity making foreign matter can not enter external toothing 9, planetary gear or driving wheel are damaged.
In the utility model, during the normal printing state of flexographic presses, power by the first sun gear 1 on driving shaft 2 by the first row star-wheel 4 that is engaged with by power transmission to the second planetary gear 8, the second planetary gear 8 is made to carry out rotation, the rotation of the second planetary gear 8 then drives the rotation of the second sun gear 7 and driven axle 3, make power transmission on printing cylinder, when needs carry out regulating version, as long as regulate worm screw 6, the external toothing 9 engaged with worm screw 6 is made to drive planet carrier 5 to rotate, the second planetary gear 8 on planet carrier 5 drives the second sun gear 7 and driven axle 3 from transferring driving shaft 2 for inactive state by its revolution and rotation, this makes it possible to make flexographic presses carry out regulating version.
Embodiment 2: the different structure of the present embodiment and embodiment 1 is that drive unit is gear 11, and this gear 11 engages with external toothing 9, and this gear 11 is also connected with power source simultaneously, and this power source also can be motor.Other structure is identical with embodiment 1, is not repeating.
