NSK bearing used in the process, many people only pay attention to a big problem. Didn't see some small issues. Often because these small problems cause bearing damage or even the end of life.
Poor is a filter effect air filter or intake system sealed well, to check the air intake system of pipes and connections, there is no break loose and, at the same time check the filter for loose paper core there is no break. Both the maintenance and the maintenance check of the entire intake system is very important, you must ensure that reliability.
Joined the engines after the second is contamination of lubricating oil or engine oil and filter use for too long all of the filters are clogged, so the lubrication oil on the surface of directly into the filter without filter.
Third, fuel and oil leakage in burning up too high volume, nozzle, resulting in fuel into the crankcase, while some impurities with fuel into the crankcase and oil mixed together reduce the lubricating effect.
Therefore engines in use to observe engine exhaust and running, as there are exceptions to identify reasons for repair or replacement in a timely manner.
Four is the engine Assembly, poor cleanliness of internal parts. At the time of repair and maintenance of engines, be sure to note parts clean, installation should pay attention to prevent further pollution, to ensure that after installation of internal cleanliness.
NSK bearing the rolling surface indentation or if there are cracks, rust, will attack like rivet rivets periodic vibration and noise, their cycles can be fixed but most speed into this corresponding relationship, scars will continue attacks on the channel, scars on the ball disappeared, and included with the unit and this noise smoothing prerequisite and inevitable change.
Such moderation approach to noise: device not a knock when bearings, NSK bearings and shaft Assembly, then avoid bearing when mounted in housings mounted helical; avoid inventory to avoid bearing corrosion and transportation impact vibration use smoothing of high viscosity grease.
Foreign bodies such as dust in the rolling bearing, will attack non-periodic vibration and the so-called dust, vibration and noise of their large and indefinite, and or with or without.
Moderation approach to dust: improving the washing of NSK bearings, bearings, shafts, before device full bore and match parts tough clean Shen Qing; put foreign objects inside the smooth agent; improve bearing seal; preventing application information pure or stick with embedded foreign body.
