The roller on the printing unit of the rotary printing device has a bearing for the two shaft ends which is a spherical roller bearing. This kind of bearing can realize the pressure and pressure of the printing machine. When the printing equipment is cured, the grease is not in place, the working time of the printing equipment is increased, and the corrosion of the cleaning fluid can cause the problem of the inner ring and the journal of the self-aligning bearing, the inner ring grinding and the like, which not only affects the problem. The normal overprinting of the rotary printing equipment also caused the phenomenon that the clutch pressure was not in place.
In the maintenance of rotary printing equipment, you need to pay attention to the following issues:
1. Power outage, shut down.
2. Remove the rubber roller in the corresponding orientation of the rotary printing equipment.
3. Remove the clutch press-bar in the wall panel, the quasi-structure of the wallboard jacket, the fixed block of the painful sleeve and the bearing plate of the outer ring of the bearing.
4. Prepare maintenance tools.
5. Use the top block to tighten the end of the roller in the rotary printing equipment that does not need to replace the bearing, and use the hanging hoist to hang the roller journal.
6. Disassemble the partial pain sleeve of the rotary printing equipment. The rotary printing equipment uses a spherical roller bearing with a tapered hole, and the distance between the bearings is changed by changing the installation interval of the bearing on the shaft. Considering that the clearance level and accuracy between the same batch of bearings are different, it is necessary to first measure the reference data and record the data, and use this data as the basic data. Then take out the bearing, install the inner retaining ring and washer, then install the bearing and record the data.
The maintenance of rotary printing equipment plays an important role in printing enterprises, especially in printing enterprises with complex equipment and large quantities. For the timeliness requirements, printing output, and regular maintenance of the rotary printing equipment, the quality of the printed products can be guaranteed.
