What are the symptoms of Huaian INA bearing caused by current corrosion?

當電流通過軸承時，滾道和滾子之間的接觸面被阻塞，導致電弧和局部高溫。每次電流被阻擋在滾珠或滾軸和滾道之間時，兩側(cè)都會有凹坑，形成凹槽。隨著槽的加深，軸承也會出現(xiàn)噪音和振動。高墻度電流，如局部短路，會造成粗糙表面并產(chǎn)生微粒。強度電流的大幅度變化會造成更嚴重的損壞，并導致滾道與滾道或鋼球之間的金屬han接。另一方面，輥上的金屬凸塊對滾道產(chǎn)生缺口效應，導致軸承噪聲和振動。

When the current passes through the bearing, the contact surface between the raceway and the roller is blocked, resulting in arc and local high temperature. Every time the current is blocked between the ball or the roller and the raceway, there will be pits on both sides, forming a groove. As the groove deepens, the bearing will also appear noise and vibration. High wall current, such as local short circuit, can cause rough surfaces and produce particles. Large changes in strength current can cause more serious damage and lead to metal Han joints between raceway and raceway or steel ball. On the other hand, the metal bump on the roll has notch effect on the raceway, which leads to bearing noise and vibration.

電弧產(chǎn)生的原因包括帶電帶或壓延輥上靜電、接線錯誤、接地不當、han接、絕緣bu良或不適當、電機轉(zhuǎn)子線圈松動、短路等。

The causes of arc include static electricity on live strip or calender roll, wrong wiring, improper grounding, Han connection, poor or inappropriate insulation bu, loosening of motor rotor coil, short circuit, etc.

淮安INA軸承故障？為什么？軸承zui近壞了。工程師們正在尋找原因，但還沒有找到。接下來，常州二瑞機電設備有限公司將帶您分析軸承故障的原因。

Huaian INA bearing failure? Why? The bearing Zui is nearly broken. Engineers are looking for the reason, but they haven't found it yet. Next, Changzhou Errui Electrical and Mechanical Equipment Co., Ltd. will take you to analyze the causes of bearing failure.

軸承失效往往是由許多因素引起的。影響設計和制造過程的所有因素都與進口軸承的失效有關(guān)。

Bearing failure is often caused by many factors. All factors affecting the design and manufacturing process are related to the failure of imported bearings.

一般來說，可以考慮和分析使用因素和內(nèi)部因素。主要使用因素是安裝調(diào)整、使用和維護是否符合技術(shù)要求。安裝前提是使用中zui重要的因素之一。由于安裝上的適當差異，軸承經(jīng)常會改變?nèi)纵S承各部分之間的應力狀態(tài)、淮安INA軸承的異常運行和早期失效。根據(jù)軸承安裝、使用、維護、監(jiān)測和檢查的技術(shù)要求，對運行中的軸承的負荷、轉(zhuǎn)速、工作溫度、振動、噪聲和潤滑前提進行檢查，發(fā)現(xiàn)異常原因，及時調(diào)整，恢復正常運行。

Generally speaking, use factors and internal factors can be considered and analyzed. The main use factor is whether the installation adjustment, use and maintenance meet the technical requirements. Installation premise is one of the important factors of Zui in use. Due to the appropriate differences in installation, bearings often change the stress state between various parts of the whole set of bearings, abnormal operation and early failure of Huaian INA bearings. According to the technical requirements of bearing installation, use, maintenance, monitoring and inspection, the load, speed, working temperature, vibration, noise and lubrication premises of the bearing in operation are inspected, and the abnormal causes are found, adjusted in time, and normal operation is restored.

內(nèi)部因素主要是結(jié)構(gòu)設計、制造工藝和材料質(zhì)量，決定了進口軸承的質(zhì)量。

Internal factors are mainly structural design, manufacturing process and material quality, which determine the quality of imported bearings.

首先，只有在結(jié)構(gòu)設計合理、改進原有結(jié)構(gòu)后，才能延長淮安INA軸承壽命。軸承通常通過鑄造、熱處理、車削、磨削和裝配工藝制造。各加工工藝的公平性、前輩的改進和無混沌也會影響軸承的使用壽命。影響軸承產(chǎn)品質(zhì)量的熱處理和磨削過程往往與軸承失效更直接相關(guān)。

Firstly, the life of Huaian INA bearing can be prolonged only after the structure design is reasonable and the original structure is improved. Bearings are usually manufactured by casting, heat treatment, turning, grinding and assembly processes. The fairness of each processing technology, the improvement of predecessors and the absence of chaos will also affect the service life of bearings. The heat treatment and grinding processes that affect the quality of bearing products are often more directly related to bearing failure.

軸承失效分析的主要任務是根據(jù)大量的背景資料、分析數(shù)據(jù)和失效形式，找出導致軸承失效的主要因素，并提出改進措施，以延長軸承的使用壽命，避免軸承突然早期失效。以上內(nèi)容可供參考。我們只能說為什么這么多軸承失效。

The main task of bearing failure analysis is to find out the main factors leading to bearing failure according to a large number of background information, analysis data and failure forms, and put forward improvement measures to prolong the service life of bearings and avoid sudden early failure of bearings. The above contents can be used for reference. We can only say why so many bearings fail.
