淮安SKF軸承是機(jī)械的重要組成部分。為了保證機(jī)器的正常運(yùn)轉(zhuǎn)，軸承是必不可少的。

Huaian SKF bearing is an important part of machinery. In order to ensure the normal operation of the machine, bearings are indispensable.

因此，軸承材料尤為重要，同時(shí)也影響軸承的使用壽命。

Therefore, bearing materials are particularly important, but also affect the service life of bearings.

軸承由特殊軸承鋼制成。堅(jiān)硬、耐用、堅(jiān)固，能夠承受比自身尺寸大幾倍的部件。

Bearings are made of special bearing steel. Hard, durable, strong, able to withstand parts several times larger than their own size.

軸承鋼用于制造滾珠、滾子和軸承環(huán)。軸承鋼具有較高且均勻的硬度、耐磨性和高彈性極限。軸承鋼中非金屬夾雜物和碳化物的化學(xué)成分、含量和分布均勻性非常嚴(yán)格，是所有鋼生產(chǎn)中**嚴(yán)格的鋼種之一。1976年，國際標(biāo)準(zhǔn)化組織（ISO）將一些等級的通用軸承鋼納入了國際標(biāo)準(zhǔn)。淮安SKF軸承鋼可分為四類：全硬化軸承鋼、表面硬化軸承鋼、不銹鋼軸承鋼和高溫軸承鋼。

Bearing steel is used to manufacture balls, rollers and bearing rings. Bearing steel has high and uniform hardness, wear resistance and high elastic limit. The chemical composition, content and distribution uniformity of non-metallic inclusions and carbides in bearing steel are very strict, and they are one of the most stringent steel grades in all steel production. In 1976, the International Organization for Standardization (ISO) incorporated some grades of general bearing steel into international standards. Huaian SKF bearing steel can be divided into four categories: fully hardened bearing steel, surface hardened bearing steel, stainless steel bearing steel and high temperature bearing steel.

軸承鋼的特點(diǎn)是什么？今天，常州軸承代理二瑞小戴將向您介紹軸承鋼的特點(diǎn)。

What are the characteristics of bearing steel? Today, Errui Xiaodai, Changzhou Bearing Agent, will introduce to you the characteristics of bearing steel.

一、接觸疲勞強(qiáng)度

I. Contact fatigue strength

在周期性載荷作用下，軸承容易發(fā)生疲勞損傷，即裂紋和剝落，是軸承的一種重要失效形式。因此，為了提高軸承的使用壽命，軸承鋼須具有較高的接觸疲勞強(qiáng)度。

Under periodic load, bearing is prone to fatigue damage, that is, crack and spalling, which is an important failure form of bearing. Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.

二。耐磨性

Two. Wear resistance

在淮安SKF軸承的工作過程中，軸承環(huán)、滾動(dòng)體和維修機(jī)構(gòu)之間不僅會(huì)發(fā)生滾動(dòng)摩擦，還會(huì)發(fā)生滑動(dòng)摩擦，使軸承零件始終處于磨損狀態(tài)。為了增加軸承零件的磨損，保持軸承的精度和穩(wěn)定性，延長使用壽命，軸承鋼應(yīng)具有良好的耐磨性。

During the working process of Huaian SKF bearing, not only rolling friction but also sliding friction will occur between bearing ring, rolling element and maintenance mechanism, which makes the bearing parts always in wear state. In order to increase the wear of bearing parts, maintain the accuracy and stability of bearings, and prolong service life, bearing steel should have good wear resistance.

三。硬度

Three. hardness

硬度是軸承質(zhì)量的重要指標(biāo)之一，直接影響接觸疲勞強(qiáng)度、耐磨性和彈性極限。軸承鋼在工作狀態(tài)下的硬度應(yīng)達(dá)到HRC61~65，使淮安SKF軸承獲得較高的接觸疲勞強(qiáng)度和耐磨性。

Hardness is one of the important indexes of bearing quality, which directly affects contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel should reach HRC61 ~ 65 in working condition, so that Huaian SKF bearing can obtain higher contact fatigue strength and wear resistance.

四、防銹性能

IV. Antirust Performance

為了避免軸承零件和產(chǎn)品在加工、發(fā)送和使用過程中的腐蝕和生銹，要求軸承鋼具有良好的防銹性能。

In order to avoid corrosion and rust of bearing parts and products in the process of processing, sending and using, bearing steel is required to have good anti-rust performance.

處理性能

Processing performance

在消耗過程中，軸承零件**須經(jīng)過許多冷熱工序。為了滿足小批量、高*效率和高質(zhì)量的要求，軸承鋼應(yīng)具有良好的加工性能。如冷熱成形性能、切削性能、淬透性等。

In the process of consumption, bearing parts have to go through many hot and cold processes. In order to meet the requirements of small batch, high efficiency and high quality, bearing steel should have good processability. Such as cold and hot forming performance, cutting performance, hardenability and so on.

軸承鋼除滿足上述基本要求外，還應(yīng)滿足適當(dāng)?shù)幕瘜W(xué)成分、平均外部結(jié)構(gòu)、較少的非金屬雜質(zhì)、符合外部缺點(diǎn)規(guī)范且不超過外部脫碳層常規(guī)濃度的要求。

In addition to meeting the above basic requirements, bearing steel should also meet the requirements of appropriate chemical composition, average external structure, less non-metallic impurities, conforming to external shortcomings specifications and not exceeding the conventional concentration of external decarbonization layer.

簡要介紹了淮安SKF軸承鋼的特點(diǎn)。我相信你對軸承鋼有一定的了解。
