Heidelberg GTO offset press failure and elimination (1)

Fault one. The reason for the messy delivery is:
1. The left and the right are not in the same side;
2. Inconsistent multiples are the failure of the delivery deceleration device.
Specific faults are as follows:
Paper delivery gear motor does not turn;
Drive shaft broken;
Deceleration drum rubber ring broken.
Troubleshooting method:
A. Exclude side flush paper failure;
B. Check the gear unit one by one.
1. Replace or repair the geared motor. Planetary gears reducer and motor are integrated, and common problems are deceleration. Planetary gears are stuck by oil and foreign matter. You can use the watch repair tool to open the end caps carefully. Remove the planet wheels one by one with tweezers and clean them. Check for seriousness. Wear, then apply high-quality lubricating oil, insert into the center wheel (ie motor cylinder housing) that has been strictly cleaned (excluding the crumbs of the chuck wheel), screw on the end cap to seal, rotate the motor shaft by hand, feel flexible sound normal Can be used. Pay attention not to apply too much lubricant, and more not to fill the gearbox space. If the motor coil burns out, the repair is very difficult because of the small size and high sealing requirements.
It is recommended to change the motor.
2. Replace the flexible shaft of the drive, or use the domestically-made similar soft shaft (φ4mm). If the shaft is not available for a moment, and the broken part of the soft shaft is short, you can redo the connector shaft. The length of the extended part is equal to the length of the soft shaft. ;
3. Replace the apron, or choose the domestic 0-type seal apron instead, easy to buy.
Fault two. Dusting anti-stick device failure reasons:
Bad air pump
2. The powder spray pipe is blocked;
3. The dust blowing belt breaks.
Troubleshooting method:
1. Check to repair the air pump. In order to prolong the service life, regular maintenance, replacement of vulnerable sheet gaskets, cleaning of filter valves,
Usually once every six months;
2. Identify and remove the blockages;
3. Replace the tape and substitute the domestic tape.
Fault three. Roller bag lining cloth rotten off reasons:
1. Flooding, pressure, fatigue and wear;
2. The external force causes rottenness.
Troubleshooting method:
1. If a small area is damaged, it can be partially adhered;
2. Replace new parts;
3. Replaced with domestic silicone cloth, the effect is acceptable, easy to buy cheap, 0.5mm thick.
Fault four. Rising paper gantry breakage, needle roller bearing damage causes: external force collision, fatigue and wear.
Troubleshooting method:
1. Welding repair or surveying and processing;
2. Car copper bushing substitute, φ10Xφ14X10;
3. Change bearings.
