鎮(zhèn)江NSK軸承在運(yùn)行中不能直接觀察到，但可以通過(guò)噪聲、振動(dòng)、溫度、潤(rùn)滑油等條件檢測(cè)軸承的異常。軸承損壞典型實(shí)例；

Zhenjiang NSK bearings can not be directly observed in operation, but can be detected by noise, vibration, temperature, lubricant and other conditions. Typical example of bearing damage;

鉚釘松動(dòng)或斷裂，滾動(dòng)體斷裂。其原因是：扭矩負(fù)荷過(guò)大、潤(rùn)滑不足、轉(zhuǎn)速變化頻繁、振動(dòng)大、軸承安裝傾斜、異物堵塞。

The rivet loosens or breaks, and the rolling body breaks. The reasons are: excessive torque load, insufficient lubrication, frequent changes in rotational speed, large vibration, inclined bearing installation, foreign body blockage.

對(duì)策：了解使用條件和潤(rùn)滑條件是否適當(dāng)，注意軸承的使用，研究保持架的選擇是否適當(dāng)，以及軸承箱的剛度是否為載荷要求。

Countermeasure: Know whether the use conditions and lubrication conditions are appropriate, pay attention to the use of bearings, study whether the selection of cages is appropriate, and whether the stiffness of the bearing box is a load requirement.

內(nèi)部或外部滑動(dòng)會(huì)導(dǎo)致鏡子或變色，有時(shí)會(huì)被卡住。其主要原因是：協(xié)調(diào)不當(dāng)、套筒擰緊不當(dāng)、溫升異常、主機(jī)負(fù)荷過(guò)大。

Sliding inside or outside can cause mirrors or discoloration and sometimes get stuck. The main reasons are: improper coordination, improper sleeve tightening, abnormal temperature rise and excessive load on the main engine.

對(duì)策：須重新檢查鎮(zhèn)江NSK軸承干涉的適用性，檢查工作條件，檢查車軸和軸承箱的精度。

Countermeasure: It is necessary to re-examine the applicability of interference of Zhenjiang NSK bearings, check working conditions and check the accuracy of axles and bearing boxes.

表面部分或完全生銹，滾動(dòng)體生銹。其原因是：貯存、包裝不當(dāng)、防銹劑不足、水和酸性溶劑侵入、直接使用手軸承。

The surface is partially or completely rusted, and the rolling body is rusted. The reasons are: improper storage, improper packaging, inadequate rust inhibitors, water and acid solvent intrusion, direct use of hand bearings.

對(duì)策：防止油庫(kù)生銹，定期不規(guī)則補(bǔ)油，加強(qiáng)密封性能，定期檢查潤(rùn)滑油，及時(shí)更換不合格或劣化油，正確使用軸承。

Countermeasure: Prevent rust in oil depot, regularly and irregularly replenish oil, strengthen sealing performance, regularly check lubricating oil, timely replace unqualified or deteriorated oil, correct use of bearings.

損傷狀態(tài)：當(dāng)金屬粉末或鎮(zhèn)江NSK軸承異物被堵塞時(shí)，凹坑形成在滾道或旋轉(zhuǎn)表面上。由于安裝的同時(shí)沖擊，在輥之間形成凹（粗糙硬度壓痕）。

Damage status: When metal powder or foreign body of Zhenjiang NSK bearing is blocked, the pit is formed on the raceway or rotating surface. Due to the simultaneous impact of the installation, a concave (Rough hardness indentation) is formed between the rollers.

原因：異物如金屬粉末咬傷。裝配或運(yùn)輸過(guò)程中的沖擊載荷太大。

Cause: foreign body such as metal powder bite. The impact load during assembly or transportation is too large.

測(cè)量：沖擊套筒。改進(jìn)的密封裝置。過(guò)濾潤(rùn)滑油。改進(jìn)組裝和使用。

Measurement: impact sleeve. Improved sealing device. Filter lubricating oil. Improved assembly and use.

損傷狀態(tài)：所謂磨損是由于摩擦引起的，如滾道表面或滾動(dòng)表面、滾子端面、軸環(huán)表面和籠凹表面。

Damage status: The so-called wear is caused by friction, such as raceway surface or rolling surface, roller end surface, axle ring surface and cage concave surface.

原因：侵入異物、銹蝕和腐蝕。潤(rùn)滑。滾動(dòng)體不規(guī)則運(yùn)動(dòng)引起的滑動(dòng)。

Reason: invasion of foreign bodies, rust and corrosion. Lubrication. Slipping caused by irregular movement of rolling elements.

措施：改進(jìn)密封裝置。清潔鎮(zhèn)江NSK軸承箱。充分過(guò)濾潤(rùn)滑油。檢查潤(rùn)滑劑和潤(rùn)滑方法。防止非線性。

Measures: improve the sealing device. Clean Zhenjiang NSK bearing box. Fully filtrate lubricating oil. Check lubricants and lubrication methods. Prevent nonlinearity.

錯(cuò)誤標(biāo)記縮進(jìn)6。軸承

Error mark indent 6. Bearing

損傷狀態(tài)：在微振動(dòng)過(guò)程中，由于滾動(dòng)體與滾道輪接觸部位的振動(dòng)和振動(dòng)，產(chǎn)生磨損，產(chǎn)生布氏壓痕。

Damage state: In the process of micro-vibration, due to the vibration and vibration of the contact part between the rolling body and the raceway wheel, wear and tear occurs and Brinell indentation occurs.

原因：運(yùn)輸過(guò)程中軸承的振動(dòng)和擺動(dòng)。小振幅振蕩運(yùn)動(dòng)。潤(rùn)滑。

Cause: vibration and swing of bearing during transportation. Small amplitude oscillatory motion. Lubrication.

措施：鉸接軸和軸承箱在運(yùn)輸過(guò)程中固定。內(nèi)環(huán)和外圈應(yīng)在運(yùn)輸過(guò)程中分開(kāi)包裝。增加預(yù)緊力以減少振動(dòng)。使用合適的潤(rùn)滑劑。

Measures: articulated shaft and bearing box are fixed during transportation. The inner ring and outer ring should be separately packed during transportation. Increase preload to reduce vibration. Use suitable lubricants.

只要我們避免這種情況，定期維護(hù)軸承就能保證軸承的正常使用壽命和性能。

As long as we avoid this situation, regular maintenance of bearings can ensure the normal service life and performance of bearings.
