Problems solved by technology
The transmission power starts from the motor, passes through the reducer, and then passes through the transmission sleeve, ball spline, pin and finally to the printing cylinder. There are many transmission links and the structure is relatively complicated.
Although this method simplifies the transmission chain and reduces the difficulty of processing and installation, it adds a lot of expensive connecting parts (ball splines) and supporting parts (multi-ring bearings) to make the motor directly drive the drum
Not only does it increase the cost, but it is also difficult to ensure the installation accuracy of these supports and related components (such as coaxiality), the circumferential runout of each roller after installation, etc.
At the same time, considering the actual operating characteristics of the printing press, the relative phase of the printing plate cylinder and the rubber cylinder should remain unchanged from the beginning to the end during the operation, so as to meet the printing process requirements, but this requires high-precision electrical control

Description
technical field [0001] The invention mainly relates to the field of printing equipment, in particular to a driving device of a printing unit. Background technique [0002] The traditional unit-type web offset press is composed of multiple printing units (for example, four printing units), and there are two driving modes for the printing units. One is the method of using one motor to drive one printing unit independently, that is, each of the four printing units is driven by one motor, so that the printing unit needs a transmission device with a very complicated structure. Not only that, this structure has very high requirements on the precision and assembly process of the transmission device. It requires transmission shafts of different sizes, layers of transmission gears, high-precision machining parts, and strict assembly processes to ensure its overall quality. Moreover, a motor is used to drive a printing unit, the mechanical structure is very complicated, and the nois...
