This is a bearing shell for the input shaft of a reducer; during operation, an alarm was triggered due to an increase in the bearing shell’s temperature. After the machine was stopped, the bearing shell ended up in this condition. Guys, could you help figure out what caused the bearing shells to become like this?
This condition of the bearing bush may be caused by poor lubrication, excessive load, insufficient cooling, or improper installation. It is necessary to check whether the lubrication system is functioning properly, whether the bearing load is excessive, whether the cooling system is effective, and whether the bearing shells are installed correctly. .
It was ground directly – is there a lack of oil?
Judging from the inspection, there is a lack of oil. As for why there is a lack of oil, the cause has not been identified. The oil holes are relatively large and not blocked
The equipment has been running continuously, and suddenly an alarm was triggered regarding the temperature of the bearing shells. Upon inspection, no cause could be found; the oil circuit was not blocked, and the equipment has been in operation for a long time with no issues so far
Ablation caused by a lack of lubrication – some high-power conveying machinery should have functions for monitoring lubricant levels, issuing temperature alarms, and even enabling emergency shutdown
When this happens suddenly, it’s either due to a lack of oil or to a small piece of the alloy layer breaking off and entering the bearing shell; this situation can occur instantly. The poster can check the bearing shell on the other side; if there’s no problem with it, then dry friction can be ruled out, and the possibility of foreign objects getting in is high.
Check it against the little notebook.
