Qingdao Slewing Bearing...Office - ! / , -Although the bearing is made of metal, it can also be damaged. No matter what hard material it is, it will be damaged, but the degree of damage is different. Everyone knows that double bearings can be damaged. The quality of deep groove ball bearings is good and they are made of very good steel. Steel is a very strong material, but it can also be damaged. The bearings run in the machine every day and are constantly rubbed, which can easily damage the bearings. , so we must also prevent bearing damage, maintain the bearings well, and do not use the bearings indiscriminately and cause unnecessary losses to ourselves.
< / , -: - ! / , -The bearing is to ensure that excessive deformation occurs during installation. This is also what must be done from these aspects. For double row deep groove ball bearings, it needs to be done. There are many things about it, and the following will introduce the effects of those aspects that need to be paid attention to.
< / , -: - ! / , - Phenomenon:
< / , -: - ! / , - ) There is no obvious sound when the engine is idling, but it makes a rattling sound (caused by the crankcase) at medium and high speeds. (Emitted within)
< / , -: - ! / , - ) The sound becomes more obvious the moment you release the accelerator after a quick refueling.
< / , -: - ! / , - ) There is no obvious change after the temperature rises. When the load increases, the sound increases.
< / , -: - ! / , - ) The sound is slower and shorter than the sound of the bearing.
< / , -: - ! / , - Diagnosis:
< / , -: - ! / , - ) The sound is clear when the engine speed transitions from idle to medium speed. As the speed increases, the sound becomes louder. For prominence, for bearing noise.
< / , -: - ! / , - ) Conduct a flameout test on a certain cylinder. If the sound weakens or disappears, it is the bearing.
< / , -: - ! / , - ) If the bearing makes a sound regardless of the speed and temperature, and the engine vibrates, and the sound does not change during the flameout test, then the bearing alloy is ablated.
