1. Failure
① Bending bearing grease too much or too little;
② bending machine bearing oil well containing impurities;
③ cover bearing and a journal or a mismatch (too loose or too tight);
④ bearing bore eccentric, and the shaft relative to wipe;
⑤ bending machine motor cover or the bearing cap is not mounted flat;
⑥ coupling between the motor and the load is not correct, or the belt too tight;
⑦ bearing gap is too large or too small;
⑧ motor shaft bent.
2. Troubleshooting
① grease required (volume 1/3-2/3);
② Clean the lubricating grease replacement;
③ repair binder available too loose, too tight to be cars, grinding journal or cover the hole, to fit;
④ repair bearing caps, to eliminate friction points;
⑤ re-assembly;
⑥ recalibrate, adjust the belt tension;
⑦ replaced with new bearings;
⑧ bending correction or replacement of mechanical and electrical machine rotor shaft. |
