運行中泰州INA軸承RNA4868出現(xiàn)故障的應(yīng)變方法 |

泰州INA軸承在使用過程中表現(xiàn)出較強的規(guī)律性和重復(fù)性,。普通優(yōu)*質(zhì)不銹鋼軸承在服役初期振動和噪聲相對較小,,但頻譜分散,,振幅小,。這可能是由于制造過程中的一些缺點,,如表面毛刺,。
Taizhou INA bearings show strong regularity and repeatability in the use process. The vibration and noise of ordinary high quality stainless steel bearings are relatively small in the initial stage of service, but the spectrum is dispersed and the amplitude is small. This may be due to some shortcomings in the manufacturing process, such as su-ce burrs.
經(jīng)過一段時間的運動,,振動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。超過三個頻率的頻率很少發(fā)生。不銹鋼軸承處于非常穩(wěn)定的狀態(tài),,進入穩(wěn)定的工作循環(huán),。連續(xù)運行后,泰州INA軸承的振動和噪聲開始增加,,有時會發(fā)生異常聲音,,但振動增加到初始失效。
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 over three frequencies rarely occur. Stainless steel bearings are in a very stable state and enter a stable working cycle. After continuous operation, the vibration and noise of INA bearing in Taizhou begin to increase, sometimes abnormal sound occurs, but the vibration increases to the initial failure.
首先,,軸承譜分析發(fā)現(xiàn)鐵含量異常,,鐵譜中含有大量的亞微米鐵磨料,潤滑油酸值異常,,表明軸承背面磨損為微動磨損,。
Firstly, bearing spectrum analysis found that iron content was abnormal, ferrography contained a large number of sub-micron iron abrasives, and acid value of lubricating oil was abnormal, indicating that the wear on the back of bearing was fretting wear.
其次,軸承光譜分析發(fā)現(xiàn)有色金屬元素濃度異常,。鐵譜中亞微米磨料較多,,潤滑油中含水量過高,酸值過高,,表明有色金屬中含有亞微米磨料,。瓷磚表面腐蝕。
Secondly, the bearing spectrum analysis found that the concentration of non-ferrous metal elements was abnormal. There are more submicron abrasives in ferrography, too high water content in lubricating oil and too high acid value, which indicates that there are submicron abrasives in non-ferrous metals. The su-ce of ceramic tile is corroded.
第三,,泰州INA軸承光譜分析發(fā)現(xiàn)鐵濃度異常,。鐵譜中有許多亞微米鐵粒子。潤滑油含水量過高或酸值過高表明滾針軸承的軸頸表面受到腐蝕,。
Thirdly, the spectrum analysis of INA bearing in Taizhou found that the iron concentration was abnormal. There are many submicron iron particles in ferrography. Excessive water content or acid value of lubricating oil indicates that the journal su-ce of needle roller bearings is corroded.
第四,,不銹鋼軸承的鐵譜圖中含有黑色切削磨料顆粒或黑色氧化物顆粒,,金屬表面的回火顏色表明軸承軸頸表面受到損傷,。
Fourthly, the ferrography of stainless steel bearings contains black cutting abrasive particles or black oxide particles, and the tempering color of the metal su-ce indicates that the bearing journal su-ce is damaged.
第五,在泰州INA軸承鐵譜中發(fā)現(xiàn)切削磨料,。磨料組合物為有色金屬,,表明軸承表面受損。
Fifth, cutting abrasives were found in the ferrography of INA bearing in Taizhou. The abrasive composition is a non-ferrous metal, indicating that the bearing su-ce is damaged.
現(xiàn)在我們知道軸承失效的原因,,我們應(yīng)該注意這些方面,。不銹鋼軸承的使用壽命自然會增加。當外部硬質(zhì)顆粒進入軸承時,,擠出機本體和滾道之間的表面會有凹痕,。此外,過大的沖擊載荷也會引起接觸表面的局部塑性變形并形成凹坑,。
Now that we know the cause of bearing failure, we should pay attention to these aspects. The service life of stainless steel bearings will naturally increase. When external hard particles enter the bearing, there will be dents on the su-ce between the extruder body and the raceway. In addition, excessive impact load can also cause local plastic deformation of the contact su-ce and form pits.
當軸承靜止時,即使載荷很小,,周圍環(huán)境的振動也會在滾道上形成均勻的凹坑,。當軸承密封不當,、灰塵或顆粒物質(zhì)進入軸承或潤滑不順暢時,會在接觸面上造成嚴重的磨損,,增加不銹鋼軸承的振動和噪聲,。
When the bearing is stationary, even if the load is small, the vibration of the surrounding environment will form a uniform pit on the raceway. When improper seal, dust or particulate matter enter the bearing or lubrication is not smooth, it will cause serious wear on the contact su-ce, increase the vibration and noise of stainless steel bearings.
