Compressive strength refers to the ability to withstand unidirectional loads without being crushed or changing in size. How to ensure the normal operation of Deep Groove Ball Bearing, and how to make the bearing undamaged to make the bearing life longer. Below, I will explain to you the precautions for ensuring the reliable operation of bearings. I hope it will be helpful to you. In general, precautions to ensure reliable operation of Deep Groove Ball Bearing are as follows:
1. The clearance of Deep Groove Ball Bearing should be appropriate. If the clearance is too large, impact will occur. If the clearance is too small, lubrication will be poor, and pads may burn.
2. Improve lubrication quality, control oil pressure, temperature, and flow rate, and strengthen oil filtration.
3. The surface quality and geometric shape of Deep Groove Ball Bearing and journal shall be strictly guaranteed.
4. Use fuel and lubricating oil that meets the specifications.
5. Controlling the temperature state of a diesel engine is detrimental to working under conditions of subcooling and overheating. In cold weather, the diesel engine should be preheated before starting and the crankshaft should be manually rolled to allow the oil to enter the friction surface.
The cleanliness of bearings has a significant impact on their lifespan. Bearing companies have conducted specialized tests for this, and the results show that the difference can be several times or even tens of times greater. The higher the cleanliness of bearings, the longer their lifespan. Experiments have shown that lubricating oils with different cleanliness levels have a significant impact on the lifespan of ball bearings. Therefore, improving the cleanliness of lubricating oil can extend the lifespan of bearings. In addition, if the lubricating oil contains dirt particles below 10um, the lifespan of bearings will also increase exponentially.
The impact on lubrication performance, as well as the decrease in bearing cleanliness, not only affects the formation of lubricating oil film, but also causes the deterioration of lubricating grease and accelerates its aging, thereby affecting the decline in lubrication performance of lubricating grease.
