Abstract
The utility model discloses a kind of forme direct drive unit, comprise servomotor, accurate retarding machine, shaft coupling, forme support, forme, pressure roller, spring bearing and position sensor cover, described forme support is fixed with the motor support base being provided with accurate retarding machine and servomotor, described accurate retarding machine is connected with forme by shaft coupling, described forme is arranged on forme support by spring bearing, and the end of forme place bearing is located at by the described position sensor enclosure.Forme direct drive unit provided by the utility model, eliminates middle mechanical driving device, and frame for movement is simpler, avoids the shortcoming causing precise decreasing because the factor such as wearing and tearing between the reaction force of mechanical device axle distortion, gear clearance.
Description
Technical field
The utility model relates to the mechanical device on a kind of printing machine, especially a kind of forme direct drive unit.
Background technology
Printing plate drive set is the chief component of shaftless rotary press, on existing shaftless rotary press, main employing tooth case external gear is connected with forme external gear, or employing tooth case internal gear be connected with forme external gear, when adopting gear and axostylus axostyle transmission system, the hysteresis quality of inevitably torsion unstability and gear, alignment all can be caused to drift about to some extent, especially in acceleration and deceleration more very.If power transmission shaft is more, longer, gear is larger, many, and its accumulated error is also larger, all can wear and tear as long as have relative motion to contact let alone mechanical part, cause precise decreasing.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of forme direct drive unit, and structure is simple, avoids the factors such as mechanical device wearing and tearing to cause the problem of precise decreasing.
In order to achieve the above object, the utility model provides a kind of forme direct drive unit, comprise servomotor, accurate retarding machine, shaft coupling, forme support, forme, pressure roller, spring bearing and position sensor cover, described forme support is fixed with the motor support base being provided with accurate retarding machine and servomotor, described accurate retarding machine is connected with forme by shaft coupling, described forme is arranged on forme support by spring bearing, and forme right-hand member is located at by the described position sensor enclosure.
Addition of position sensor at forme right-hand member, form closed-loop control together with spindle encoder, can increase substantially Electric Machine Control precision, the form of this Direct driver makes gravure unit under guarantee high speed and high precision performance, has more flexibility.
The beneficial effects of the utility model are: forme direct drive unit provided by the utility model, eliminate middle mechanical driving device, frame for movement is simpler, avoids the shortcoming causing precise decreasing because the factor such as wearing and tearing between the reaction force of mechanical device axle distortion, gear clearance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-servomotor; 2-accurate retarding machine 3-shaft coupling; 4-forme support 5-forme; 6-pressure roller; 7-spring bearing; 8-position sensor cover.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, a kind of forme direct drive unit, comprise servomotor (1), accurate retarding machine (2), shaft coupling (3), forme support (4), forme (5), pressure roller (6), spring bearing (7) and position sensor cover (8), described forme support (4) is fixed with the motor support base being provided with accurate retarding machine (2) and servomotor (1), described accurate retarding machine (2) is connected with forme (5) by shaft coupling (3), described forme (5) is arranged on forme support (4) by spring bearing (7), described position sensor cover (8) is sheathed on forme right-hand member.
In the present embodiment, addition of position sensor, form closed-loop control at forme right-hand member together with spindle encoder, can increase substantially Electric Machine Control precision, the form of this Direct driver makes gravure unit under guarantee high speed and high precision performance, has more flexibility.
