產(chǎn)品詳情
在某些載荷下,淮安NSK軸承在點(diǎn)蝕前經(jīng)歷的旋轉(zhuǎn)次數(shù)或小時(shí)數(shù)稱(chēng)為軸承壽命。
Under some loads, the number of rotations or hours that Huaian NSK bearings undergo before pitting corrosion is called bearing life.
滾動(dòng)軸承的壽命由旋轉(zhuǎn)次數(shù)(或給定速度下的工作小時(shí)數(shù))決定。在此壽命期間,軸承應(yīng)在任何軸承環(huán)或滾動(dòng)元件上遭受初始疲勞損傷(剝落或缺點(diǎn))。但是,相同外觀的軸承在相同的工作條件下,無(wú)論是在實(shí)驗(yàn)室試驗(yàn)中還是在實(shí)際使用中,其實(shí)際壽命都有明顯的不同。此外,軸承“壽命”有幾個(gè)不同的定義,其中之一就是所謂的“工作壽命”。也就是說(shuō),軸承的實(shí)際壽命是由磨損前的損壞造成的。損壞通常不是由疲勞引起的,而是由磨損、腐蝕、密封損壞等原因引起的。
The life of rolling bearings is determined by the number of rotations (or working hours at a given speed). During this life, the bearing shall suffer initial fatigue damage (spalling or defect) on any bearing ring or rolling element. However, the actual life of bearings with the same appearance is obviously different under the same working conditions, whether in laboratory test or in actual use. In addition, bearing "life" has several different definitions, one of which is the so-called "working life". That is to say, the actual life of the bearing is caused by the damage before wear. Damage is usually not caused by fatigue, but by wear, corrosion, seal damage and other reasons.
為了確定淮安NSK軸承壽命標(biāo)準(zhǔn),將軸承壽命與可靠性聯(lián)系起來(lái)。
In order to determine the life standard of Huaian NSK bearings, bearing life and reliability are bed.
由于制造精度和材料均勻性的差異,即使在相同的工作條件下使用同一材料和同一批相同尺寸的軸承,其壽命也會(huì)有所不同。如果統(tǒng)計(jì)壽命為1單位,則**長(zhǎng)相對(duì)壽命為4單位,zui短相對(duì)壽命為0.1-0.2單位。zui長(zhǎng)壽命與zui短壽命之比為20-40倍。90百分比的軸承不會(huì)產(chǎn)生點(diǎn)蝕。所經(jīng)歷的旋轉(zhuǎn)次數(shù)或小時(shí)數(shù)稱(chēng)為淮安NSK軸承的額定壽命。
Because of the difference of manufacturing accuracy and material unibity, even if the same material and the same batch of bearings of the same size are used under the same working conditions, their life will be different. If the statistical life is 1 unit, the ** long relative life is 4 units and the Zui short relative life is 0.1-0.2 units. The ratio of long life of Zui to short life of Zui is 20-40 times. 90% bearing will not produce pitting corrosion. The number of rotations or hours experienced is called the rated life of Huaian NSK bearings.
額定動(dòng)載荷
Rated dynamic load
為了比較軸承的耐點(diǎn)蝕性,規(guī)定當(dāng)軸承的額定壽命為100萬(wàn)轉(zhuǎn)(106)時(shí),軸承能承受的**大載荷為基本額定動(dòng)載荷,用C表示。
In order to compare the pitting corrosion resistance of bearings, it is stipulated that when the rated life of bearings is 1 million revolutions (106), the ** large load that bearings can bear is the basic rated dynamic load, expressed in C.
也就是說(shuō),在額定動(dòng)載荷C下,100萬(wàn)轉(zhuǎn)/分(106)時(shí)軸承無(wú)點(diǎn)蝕失效的可靠性為90/100。C值越大,承載力越高。
That is to say, under rated dynamic load C, the reliability of the bearing without pitting failure is 90/100 at 1 million rpm (106). The larger the C value, the higher the bearing capacity.

一。離心軸承是純徑向載荷。
One. Centrifugal bearings are pure radial loads.
二。推力球軸承是純軸向載荷。
2. Thrust ball bearings are pure axial loads.
三。離心止推淮安NSK軸承是由純徑向位移產(chǎn)生的徑向構(gòu)件。
Three. Centrifugal thrust Huaian NSK bearing is a radial component generated by pure radial displacement.
這些是軸承的一些參數(shù)。我希望你對(duì)這個(gè)軸承有所了解。
These are some beters of the bearing. I hope you know something about this bearing.
推力球軸承分為單向和雙向兩種。它們只能承受軸向載荷,不能承受任何徑向載荷。推力軸承分為緊環(huán)和環(huán)兩部分。環(huán)由襯套擰緊,活套支撐在軸承座上。環(huán)和輥通常由滾動(dòng)軸承鋼制成,具有高*強(qiáng)度和良好的耐磨性。淬火后的表面硬度應(yīng)達(dá)到HRC60-65?;\子是用軟鋼做的。它也可以由銅合金膠合板或塑料制成。
Thrust ball bearings are divided into two types: one-way and two-way. They can only withstand axial loads and can not withstand any radial loads. Thrust bearing is divided into two parts: tight ring and ring. The ring is tightened by the bushing, and the looper is supported on the bearing seat. Rings and rolls are usually made of rolling bearing steel with high strength and good wear resistance. The surface hardness after quenching should reach HRC60-65. The cage is made of soft steel. It can also be made of copper alloy plywood or plastic.
推力角接觸球淮安NSK軸承的接觸角一般為60度。推力角接觸球軸承通常是雙向推力角接觸球軸承。主要用于精*密機(jī)床主軸。它們通常與雙列圓柱滾子軸承一起使用。它們能承受雙軸載荷。本實(shí)用新型具有精度高、剛性好、溫升低、速度快、拆裝方便等優(yōu)點(diǎn)。
The contact angle of thrust angular contact ball Huaian NSK bearing is generally 60 degrees. Thrust angular contact ball bearings are usually bi-directional thrust angular contact ball bearings. Mainly used for precision machine tool spindle. They are usually used with double row cylindrical roller bearings. They can withstand biaxial loads. The utility model has the advantages of high accuracy, good rigidity, low temperature rise, fast speed, convenient disassembly and assembly, etc.
