產(chǎn)品詳情
INA軸承故障預(yù)防在使用過程中具有很強(qiáng)的規(guī)律性和重復(fù)性。品質(zhì)優(yōu)良的不銹鋼軸承在使用初期振動(dòng)和噪聲小，但頻譜分散，振幅小。這可能是由于制造過程中的一些缺點(diǎn)造成的，例如表面粗糙度。
INA bearing fault prevention has strong regularity and repeatability in the use process. Stainless steel bearings with good quality have low vibration and noise at the initial stage of service, but the frequency spectrum is dispersed and the amplitude is small. This may be due to some shortcomings in the manufacturing process, such as surface roughness.
經(jīng)過一段時(shí)間的運(yùn)動(dòng)，振動(dòng)和噪聲保持在一定的水平，頻譜非常單一，只有頻率的一到兩倍。頻率超過三個(gè)頻率的情況很少發(fā)生。不銹鋼軸承處于非常穩(wěn)定的狀態(tài)，進(jìn)入穩(wěn)定的工作循環(huán)。
After a period of movement, the vibration and noise remain at a certain level, the spectrum is very single, only one or two times the frequency. Frequencies exceeding three frequencies rarely occur. Stainless steel bearings are in a very stable state and enter a stable working cycle.
連續(xù)運(yùn)行后，軸承的振動(dòng)和噪聲開始增大，有時(shí)會(huì)出現(xiàn)異常聲音，但振動(dòng)增大到初始故障。
After continuous operation, the vibration and noise of the bearing begin to increase, sometimes abnormal sound will appear, but the vibration increases to the initial fault.
首先，軸承光譜分析發(fā)現(xiàn)，有色金屬元素濃度異常，INA軸承故障預(yù)防鐵譜中出現(xiàn)大量有色金屬成分的亞微米磨損顆粒。潤(rùn)滑油的含水量和酸值過高表明軸承表面受到腐蝕。
First of all, bearing spectrum analysis found that the concentration of non-ferrous bl elements is abnormal, INA bearing fault prevention ferrography appears a large number of sub-micron wear particles of non-ferrous bl components. Excessive water content and acid value of lubricating oil indicate that the bearing surface is corroded.
其次，軸承光譜分析發(fā)現(xiàn)鐵濃度異常，鐵譜中存在亞鐵亞微米磨損顆粒，潤(rùn)滑油的水酸值異常，說明軸承磨損是由微動(dòng)引起的。
Secondly, bearing spectrum analysis found that iron concentration was abnormal, ferrous submicron wear particles existed in ferrography, and water acid value of lubricating oil was abnormal, which indicated that bearing wear was caused by fretting.
第三，不銹鋼軸承的鐵譜中含有黑色切削磨?；蚝谏趸镱w粒，金屬表面的回火顏色表明軸承軸頸表面損壞。
Thirdly, the ferrography of stainless steel bearings contains black cutting abrasive particles or black oxide particles, and the tempering color of the bl surface indicates that the bearing journal surface is damaged.
第四，INA軸承故障預(yù)防鐵譜中發(fā)現(xiàn)切削磨料，磨料成分為有色金屬，表明軸承表面損壞。
Fourthly, cutting abrasives are found in INA bearing failure prevention ferrography. The abrasive comb is non-ferrous bl, indicating that the bearing surface is damaged.
第五，軸承光譜分析發(fā)現(xiàn)，鐵的異常濃度，存在許多亞微米鐵顆粒，潤(rùn)滑油水分或酸值超標(biāo)，說明滾針軸承的軸頸表面受到腐蝕。
Fifth, bearing spectrum analysis found that the abnormal concentration of iron, there are many submicron iron particles, lubricating oil moisture or acid value exceeded the standard, indicating that the journal surface of needle roller bearings was corroded.
既然我們知道軸承失效的原因，就應(yīng)該注意這些方面。不銹鋼軸承的使用壽命自然增加。
Since we know the cause of bearing failure, we should pay attention to these aspects. The service life of stainless steel bearings increases naturally.
當(dāng)外部硬顆粒進(jìn)入軸承并壓在軸承體和滾道之間時(shí)，表面會(huì)產(chǎn)生凹痕。此外，過大的沖擊載荷還會(huì)導(dǎo)致接觸面局部塑性變形，形成凹坑。當(dāng)INA軸承故障預(yù)防靜止時(shí)，即使負(fù)載很小，周圍環(huán)境的振動(dòng)也會(huì)在滾道上形成均勻的凹坑。
When the external hard particles enter the bearing and press between the bearing body and the raceway, the surface will produce dents. In addition, excessive impact load will also lead to local plastic debation of the contact surface, bing pits. When INA bearings fail to prevent static, even if the load is small, the vibration of the surrounding environment will b a unib pit on the raceway.
當(dāng)軸承密封bu良、灰塵或顆粒物進(jìn)入軸承或潤(rùn)滑bu良時(shí)，會(huì)造成接觸面嚴(yán)重磨損或磨損，增加不銹鋼軸承的振動(dòng)和噪音。
When the bearing seal Bu Liang, dust or particulate matter enter the bearing or lubrication Bu Liang, it will cause serious wear or wear of the contact surface, and increase the vibration and noise of stainless steel bearings.
在檢查之前，應(yīng)清潔機(jī)器表面，并拆下軸承周圍的零件。油封是非常脆弱的零件，需要仔細(xì)拆卸，不要用力過大，然后仔細(xì)檢查油封及其周圍零件，如果有bu良癥狀，bi須更換，bu良的油封會(huì)導(dǎo)致軸承損壞，并嚴(yán)格關(guān)閉設(shè)備。
Before inspection, the machine surface should be cleaned and the parts around the bearing should be removed. Oil seals are very fragile parts, need to be carefully removed, not too hard, and then carefully inspect the oil seals and their surrounding parts, if there are good symptoms of bu, Bi must be replaced, Bu good oil seals will lead to bearing damage, and strict closure of equipment.
檢查INA軸承故障預(yù)防潤(rùn)滑油，用手指間的少許油擦拭。如果有任何污染物，你可以感覺到它，或者在你的手背上涂一層薄薄的潤(rùn)滑劑，然后關(guān)燈。
Inspect INA bearing failure to prevent lubricating oil, wipe with a little oil between fingers. If there is any contaminant, you can feel it, or put a thin layer of lubricant on the back of your hand, and turn off the light.
