Koyo thrust ball bearing tiny particles damage resulting in noise detection method

Koyo bearing in the process of use, many people only pay attention to the problem. I don't see a few small problems. Often because these little problem thrust ball bearing damage or end of life. A is the difference in the filtration effect of air filter or the air intake system sealing is not good, want to check the air intake system inlet pipe and joint, presence of rupture and loose, at the same time look for broken filter without looseness, paper core. Whether repair or maintenance of the air intake system inspection is very important, must ensure the reliability. Second, lubricating oil contaminated after joining engine or engine oil and filter using a long time all machine filter blockage, makes all lubricating oil on the surface of the directly into the filter without filtration. 3 it is burning up large amount of fuel oil supply, nozzle leakage, causing oil into the crankcase, at the same time some impurities with the decreasing fuel into the crankcase oil and mix together the lubrication effect. So the engine in use should pay attention to observe the workings of the engine exhaust smoke and, if there is any abnormal to timely find out the reason for repair or replacement. Four is the engine assembly, the purity of the internal parts. When repair and maintenance of the engine, be sure to pay attention to the parts, when installation should pay attention to prevent pollution, to ensure the purity of the installed inside. Thrust ball bearing rolling appearance if there is crack, indentation, or rust, like rivet rivet will attack the periodic vibration and noise, the cycle can be fixed but mostly, the corresponding relationship between rotating speed into the inevitable scars will continue in the channel, and scars on the ball, and the noise with the device and smooth and there is a premise of transformation. Device for this kind of noise control method are: no rap koyo bearings, thrust ball bearing and shaft assembly after a load bearing seat when avoid bearing oblique; Inventory to avoid the bearing corrosion and transportation to avoid the impact of vibration; Using high viscosity of smooth and fat. Rolling bearing with dust and other foreign body, will attack the periodic vibration and so-called dust, the vibration and noise of intrusive, and with or without. Dust acoustic control measures are: to improve the measures for the cleaning of thrust ball bearing device before the koyo bearing, shaft and hole and matching parts all stern qing shen clean; Clear smooth agent inside the foreign body; To improve the bearing seal; Avoid using data not pure frame or foreign bodies are embedded.
