Precautions during bearing maintenance

1. Disassembly skills of bearing seat ring

Some mechanical equipment is prone to damage to the connecting rod bearing. After the bearing is damaged, the outer ring remains in the connecting rod hole, and it is difficult to disassemble. Because all the steel in the outer ring is relatively hard, the hacksaw is easy to slip when sawing, but Hitting too hard can damage the connecting rod. At this time, the connecting rod can be fixed on the vise, and the connecting rod hole can be held against the connecting rod hole with a sleeve head whose size is slightly larger than the size of the connecting rod bearing hole through the hedging head of a heavy-duty socket wrench, while the hedging head with a size slightly smaller than the size of the connecting rod bearing hole is used to withstand the connecting rod hole. The sleeve head on one side bears against the outer ring of the bearing, and finally increases the clamping force appropriately, and slowly presses the outer ring of the bearing out.

2. Problems with the bearing itself

When maintaining mechanical equipment, maintenance personnel should fully grasp the code and model information of the corresponding bearings, and avoid using other types of bearings to replace the original bearings. At present, there is a large quality difference among the bearings available in the market, and the occurrence rate of problems such as shoddy and shoddy is high, and even some bearings will be reduced in quality or performance due to long storage time, so , Before the maintenance of mechanical equipment bearings and the replacement of new bearings, it is necessary to conduct a comprehensive and accurate check of the relevant information of the bearings, and test their performance and appearance to improve the quality of the bearings.

3. Do not pretend to be reversed

In the process of mechanical equipment maintenance, it is necessary to accurately grasp the direction requirements of mechanical bearings. Only correct installation can provide guarantee for its operation. Because the external features of some mechanical bearings are not very obvious, they can be installed in any direction, so the problem of reverse installation often occurs. Therefore, when assembling bearings, maintenance personnel need to fully understand and accurately grasp the installation and structural requirements of the bearings, and fully understand the relevant provisions of the manual to ensure the accuracy and efficiency of bearing maintenance work.
