9、the 川ustrations.二.滾動軸承的工作溫度通常，軸承的溫度隨著運轉(zhuǎn)的開始慢慢上升,12小時后達到穩(wěn)定的工作狀態(tài) .如果潤滑、安裝不合適，則軸承溫度會急驟上升，出現(xiàn)異常高溫，這時必須停止運轉(zhuǎn)， 采取必要的防范措施.滾動軸承的工作溫度不得超過 95C,報警溫度為90C,停機溫 度為95c.據(jù)用戶的需求，每個軸承可設(shè)測溫元件（Pt100）,將其引線引入測溫接線盒 內(nèi),提供遠傳溫度信號或進行溫度顯示.軸承測溫點的位置距離軸承外圈不超過 10mm.2. Working Temperature of Rolling Element BearingGenerally the bearing te

10、mperature rises gradually and shall be stabilized in 1 or 2 hours. The bearing temperature will increase rapidly if the grease (oil) or assembly does not match the bearing. If so the motor shall be stopped immediately to take necessary actions.The working temperature for rolling element bearing is 9

11、5 c. Upon request Pt100s are equipped as monitoring detectors for bearing temperature. The detectors will alarm if the bearing temperature reaches 902 and the motor will stop if the bearing temperature reaches 95 c.The lead wires of detectors are brought out to the auxiliary terminal box for remote

12、control or signal indication. The bearing temperature measuring points shall not exceed 10mm far away from the outer bearing race.三.滾動軸承的潤滑方式及潤滑劑軸承潤滑的目的是要在構(gòu)成軸承的滾道輪、滾動體及保持架相互接觸的部分形成一層油膜,以防止各面直接接觸，具有減少摩擦及磨損、延長疲勞壽命、排出摩擦熱、防 止異物侵入、防止生銹與腐蝕的作用潤滑的方式有兩種，即脂潤滑和油潤滑。我公司高壓電機滾動軸承的潤滑方式絕大部分為脂潤滑，但有少數(shù)稀油潤滑 , 電機的潤滑方式標注在

13、電機的注油牌上 , 請按注油牌 的內(nèi)容加注潤滑脂或潤滑油 .對于稀油潤滑的滾動軸承, 我們推薦使用的潤滑油為 : 汽輪機油 L-TSA46. 但粘度為ISOVG46的其他品種的潤滑油也可使用.首次加油前,油室應用清漬油沖洗清理干 凈。 使用時應經(jīng)常注意油標的油位顯示, 如果油位低于油標的中心線, 應立即補充潤滑油 . 據(jù)用戶的需求, 每個軸承裝置可安裝恒位油杯(自動油位器) ，以在較長時間內(nèi)自動保持油室油位在規(guī)定油位上，確保滾動軸承的最佳潤滑狀態(tài)。關(guān)于潤滑脂的選用 , 我們提供如下建議:1. 各種潤滑脂主要由基礎(chǔ)油、增稠劑、添加劑組成的 , 同一個種類的潤滑脂, 牌號不同性能相差很大, 因此原

14、則上, 牌號不同的潤滑脂不能混合使用 , 避免潤滑脂的性能的降低.2. 選用潤滑脂時, 應考慮軸承的工作溫度、工作速度、軸承的種類與大小、負荷狀況、外部環(huán)境, 詳情請咨詢潤滑脂的供應商.3. 本公司高壓電機使用的潤滑脂為：長城HTHSW承潤滑脂.3. Regreasing Method and LubricationThe purpose of lubricating is to form a film around the contacting parts of rolling runner, rolling body and the holder to prevent them from

15、direct contact , minimize fraction and loss, prolong the service life, transfer heat as well as protect the bearing from the ingress of substances, rust and corrosion.The rolling element bearings adopt grease or oil lubrication. The lubricating method is indicated in the regreasing plate. Please kin

16、d read the regreasing plate for lubrication.If the rolling element bearings adopt oil lubrication, steam turbo oil L-TSA46 or other equivalent oils with viscosity ISOVG46 are recommended. The oil chamber shall be cleared by clean oil before regreasing. Attention shall be paid to the oil level indica

17、tion during operation. Oil shall be filled in if the oil level is lower than the central line of the indication. Automatic oil level device can be added if required by customer.Comments on lubrication selection:a) Different greases (oils) can not be mixed.b) The working temperature, speed, bearing t

18、ype and size, load and ambient shall be considered when select the grease or oil. Please consult the grease (oil) supplier.c) Great Wall HTHS Bearing Grease for motors is preferable.四.滾動軸承的維護與保養(yǎng)儲存期超過半年或停機超過2 個月后再次使用的電機, 應先檢查軸承裝置的狀況 ,如有嚴重污染、無油、油干、零件銹蝕等狀況時, 需將電機的軸承裝置部分解體, 徹底清洗軸承及與軸承相關(guān)的部件( 注油管、軸承內(nèi)蓋、 軸承

19、外蓋、擋油環(huán)、排油盒等), 然后重新加注潤滑脂 (油) , 加注潤滑脂時, 滾動軸承內(nèi)部應加滿潤滑脂, 軸承內(nèi)蓋與軸承外蓋所形成的空腔的填脂量為整個空腔的1/31/2 ;加注潤滑油時，通過注油嘴向油室加注潤 滑油，加至油位到油標的中心線以上至三分之二處。潤滑脂 (油) 經(jīng)過一段時間使用以后 , 特性會變差 , 潤滑功能會降低, 因此要適時補充潤滑脂或更換潤滑油。 潤滑脂補充的時間間隔與補充數(shù)量打在電機的注油牌上 , 應按照注 油牌數(shù)據(jù)及時補充潤滑脂，潤滑油每三個月更換一次, 才能保證滾動軸承的可靠運行.注油牌上的加油周期及數(shù)量適用于軸承溫度70及以下工作狀態(tài), 但當軸承溫度超過 70時 , 軸

20、承溫度每上升15 , 潤滑脂的補充間隔時間減少一半.在設(shè)備定期檢修時 , 為了電機在下一檢修周期內(nèi)的可靠運行, 應拆檢軸承裝置, 必要時更換軸承.4. MaintenancesFor motors stored more than six months or not in use more than 2 months, the bearing device shall be checked before operation. The bearing device shall be disassembled and cleaned (especially grease pipe, inner b

21、earing cap, outer bearing cap, slinger and drainage) if contamination, shortage of grease, dry grease or rust occurs. The grease or oil shall be filled in. The internal of rolling element bearing shall be full of grease (oil), and one-third to half of the bearing chamber shall be filled. When fillin

22、g by grease nipple, the grease (oil) level shall be at the central line or two-third higher than the indication.The filling interval for rolling element bearing is 3 months. The interval and filling amount in the lubrication plate is based on the bearing temperature up to 70 . The filling interval s

23、hall be reduced by half if the bearing temperature rises by every 15 .The motor shall be inspected and maintained periodically. The bearing device shall be disassembled to check. The bearing shall be replaced if necessary.五 . 軸承安裝與拆檢時應注意的事項 .在軸承的拆裝中應注意以下內(nèi)容:1. 保持軸承及周圍清潔, 使灰塵不至于侵入軸承.2. 小心謹慎地使用軸承. 在使用中

24、給與軸承強烈的沖擊, 會產(chǎn)生傷痕與壓痕, 成為事故的原因 . 應使用恰當?shù)牟僮鞴ぞ?3. 要注意軸承的銹蝕 . 手上的汗會成為軸承生銹的原因 .4. 如果拆下的軸承要重新使用 , 或安裝軸承時, 拆裝軸承的作用力要作用在滾動軸承的內(nèi)圈上, 絕對不能作用在軸承的其他部位.5. 熱裝滾動軸承時, 在加熱的任何點 , 溫度均不能高于120 . 避免造成滾動軸承的變形和再次退火.6. 安裝滾動軸承時, 確保標示軸承型號的一邊朝外. 軸承的型號均打在軸承內(nèi)圈或外圈的端面.7. 清洗滾動軸承時, 應分兩次清洗. 粗洗時 , 用刷子或無絨布蘸清漬油或汽油清洗, 清洗時不應轉(zhuǎn)動軸承. 精洗時 , 將軸承放入干

25、凈的油池內(nèi)邊轉(zhuǎn)動軸承邊清洗.5. Attentions for Bearing Assembly and Disassemblya) Keep the bearing clean to protect from the ingress of dust;b) Take the bearing carefully to avoid strong impact which will result in damage. Suitable instruments are recommended.c) Do not touch the bearing by hand directly. This may

26、cause rust.d) When assemble or disassemble the bearing, any force shall be added to the inner bearing race.Other locations are prohibited.e) When hot fit the bearing, the temperature at any points shall not exceed 12 0.f) When assemble the bearing, the surface with bearing size shall be putto the ou

27、tside.g) The bearing shall be cleaned in two steps. First clean the bearing with gasoline by brush or cloth, then put the bearing into gasoline and clean it by turning.六 . 運轉(zhuǎn)檢查與故障處理運轉(zhuǎn)中的檢查項目有軸承滾動聲、振動、溫度、潤滑狀態(tài)等, 如有異常狀態(tài), 按附表2 處理 .判斷軸承可否再次使用 , 要考慮軸承損傷的程度、機器性能、重要性、運轉(zhuǎn)條件、及檢查周期等. 如有下列缺陷 , 軸承不能使用 .1. 內(nèi)外環(huán)、滾動體、

28、保持架中有裂紋和出現(xiàn)碎片 .2. 內(nèi)外環(huán)、滾動體中有剝離的 .3. 滾道面、擋邊、滾動體有顯著卡傷.4. 保持架的磨損顯著或鉚釘松動.5. 滾道面、滾動體有生銹和傷痕.6. 滾道面、滾動體有顯著的壓痕和打痕.7. 內(nèi)環(huán)內(nèi)徑面或外環(huán)外徑面有蠕變.8. 過熱變色厲害.6. Check and Failure SolutionsDuring operation bearing rolling sound, vibration, temperature and lubrication shall beobserved. Any abnormal cases shall be solved accord

29、ing to Table 2.Whether a bearing can be re-utilized depending on the damage, property, importance, operation condition and the inspection period. The bearing shall not be re-utilized if the following default occurs:a) crack or crush in inner or outer ring, rolling body or holder;b) stripping in inne

30、r or outer ring or rolling body;c) clamping injury in rolling surface, edge or rolling body;d) significant wearing or loosing pin of holder;e) rust or injury of rolling surface or rolling body;f) significant extruding or hitting signs in rolling surface or rolling body;g) creeping in inner ring ID s

31、urface or outer ring OD surface;h) discolor due to over heat.七 . 軸承滾動聲的附加說明由于滾動軸承是旋轉(zhuǎn)部件, 在運轉(zhuǎn)過程中 , 不可避免要發(fā)出各種聲音, 在檢查軸承的滾動聲時 , 應據(jù)滾動聲的大小及音質(zhì)進行辨別 , 以區(qū)分正常聲音與異常的聲音 , 但軸承聲響的判斷, 國內(nèi)外尚無定量的標準, 我們認為是: 在整機噪聲合格, 振動合格 , 軸承溫度合格的前提下 , 軸承聲響連續(xù)、無間歇雜音；運行平穩(wěn)、無起伏；聲響均勻無尖叫，此種情況下的軸承響聲并不影響軸承的使用，是正常的滾動聲, 電機可正常使用7.
