為了充分觀察機(jī)器的定期檢查和更換,并拆下軸承,檢查滾道表面狀況和是否沒有損壞,是否可以重復(fù)使用,見第5項(xiàng):進(jìn)口軸承的檢查.運(yùn)行中的檢查項(xiàng)目包括INA軸承的滾動(dòng)聲、振動(dòng),、溫度和潤(rùn)滑狀況.具體如下:在運(yùn)行中發(fā)現(xiàn)異常情況時(shí).

In order to fully observe the regular inspection and replacement of the machine, and remove the bearings, check the raceway su-ce condition and whether there is no damage, whether it can be reused, see item 5: inspection of imported bearings. Inspection items in operation include rolling sound, vibration, temperature and lubrication of INA bearings. Specifically as follows: when abnormal conditions are found in operation.

通過麥克風(fēng)檢查軸承的滾動(dòng)聲音.即使進(jìn)口軸承有輕微的剝落損傷,也會(huì)產(chǎn)生不正常,、不規(guī)則的聲音,可以用麥克風(fēng)分辨.

Check the rolling sound of the bearing through the microphone. Even if the imported bearing has slight peeling damage, it will produce abnormal and irregular sound, which can be distinguished by microphone.

軸承振動(dòng)對(duì)軸承的剝落、壓痕,、生銹,、裂紋、磨損等損傷非常min感,在軸承振動(dòng)測(cè)量中可以反映出來.因此,可以使用專用的軸承振動(dòng)測(cè)量裝置(頻率分析儀等)來測(cè)量振動(dòng),不能從頻率中推斷出異常情況.根據(jù)INA軸承的工作情況或傳感器的安裝位置,測(cè)量值從今天到今天都有變化,因此在確定判斷標(biāo)準(zhǔn)之前,有必要對(duì)每臺(tái)機(jī)器的測(cè)量值進(jìn)行分析比較.

Bearing vibration is very sensitive to the damage of bearing such as spalling, indentation, rust, crack and wear, which can be reflected in bearing vibration measurement. Therefore, the special bearing vibration measuring device (frequency analyzer, etc.) can be used to measure vibration, and the abnormal situation can not be inferred from the frequency. According to the working condition of INA bearings or the installation position of sensors, the measured values vary from today to today, so it is necessary to analyze and compare the measured values of each machine before determining the judgment criteria.

進(jìn)口軸承的溫度可以從軸承外部的溫度獲得.如果油孔能直接測(cè)量軸承外圈的溫度,則更為合適.通常情況下,軸承的溫度隨著運(yùn)行開始緩慢上升,1-2小時(shí)后達(dá)到穩(wěn)定狀態(tài).軸承室溫度隨機(jī)化器的熱容量,、散熱量,、轉(zhuǎn)速和負(fù)荷不同.如果潤(rùn)滑和安裝部件合適,軸承溫度將急劇上升,并出現(xiàn)異常高溫.這時(shí),我們須停止工作,采取必要的預(yù)防措施.根據(jù)大量試驗(yàn)數(shù)據(jù),本表列出了各種INA軸承外圈的平均溫度,供參考.

The temperature of the imported bearing can be obtained from the temperature outside the bearing. If the oil hole can directly measure the temperature of the bearing outer ring, it is more suitable. Usually, the temperature of the bearing rises slowly with the start of operation and reaches a stable state after 1-2 hours. The heat capacity, heat dissipation, rotational speed and load of bearing chamber temperature randomizer are different. If the lubrication and installation parts are suitable, the bearing temperature will rise sharply and abnormal high temperature will occur. At this time, we must stop working and take necessary precautions. According to a large number of test data, the average temperature of various INA bearing outer rings is listed in this table for reference.

軸承潤(rùn)滑對(duì)滾動(dòng)軸承的疲勞壽命、摩擦,、磨損,、溫升和振動(dòng)起著重要作用.沒有正常潤(rùn)滑,軸承就不能工作.對(duì)軸承損壞原因的分析表明,約40個(gè)百分比的軸承損壞與潤(rùn)滑bu良有關(guān).因此,良好的軸承潤(rùn)滑是降低軸承摩擦磨損的you效措施.此外,軸承的潤(rùn)滑還具有散熱、防銹,、密封和減震等功能.軸承的潤(rùn)滑可簡(jiǎn)單描述如下:

Bearing lubrication plays an important role in the fatigue life, friction, wear, temperature rise and vibration of rolling bearings. Bearings cannot work without normal lubrication. The analysis of the causes of bearing damage shows that about 40% of bearing damage is related to good lubrication bu. Therefore, good bearing lubrication is a youeffect measure to reduce bearing friction and wear. In addition, the lubrication of bearings also has the functions of heat dissipation, rust prevention, sealing and shock absorption. The lubrication of bearings can be simply described as follows:

a.在兩個(gè)滾動(dòng)或滑動(dòng)表面之間形成油膜,分離兩個(gè)表面,減少接觸表面的摩擦和磨損.

A. Forming oil film between two rolling or sliding su-ces, separating the two su-ces, reducing friction and wear on the contact su-ce.

b.使用INA軸承油潤(rùn)滑時(shí),特別是使用循環(huán)油潤(rùn)滑,、油霧潤(rùn)滑和噴油潤(rùn)滑時(shí),潤(rùn)滑油可以帶走軸承的大部摩擦熱,起到散熱的作用.

B. When using INA bearing oil lubrication, especially when using circulating oil lubrication, oil mist lubrication and oil injection lubrication, the lubricant can take away most of the friction heat of the bearing and play the role of heat dissipation.

c.油脂潤(rùn)滑可防止灰塵等異物進(jìn)入軸承,起到密封作用.

C. Grease lubrication can prevent foreign matter such as dust from entering the bearing and play a sealing role.
