鎮(zhèn)江NSK軸承是一種元件，廣泛應(yīng)用于各個(gè)領(lǐng)域，根據(jù)結(jié)構(gòu)或類型分為多種，并根據(jù)摩擦特性來(lái)分類常見(jiàn)的滾動(dòng)軸承和滑動(dòng)軸承，兩者都有所不同。滾動(dòng)軸承的摩擦阻力遠(yuǎn)小于滑動(dòng)軸承的摩擦阻力。它具有啟動(dòng)快、效率高的優(yōu)點(diǎn)。與滑動(dòng)軸承相比，滾動(dòng)軸承是大的優(yōu)點(diǎn)。但是也有缺點(diǎn)，即尺寸較大，所以吸收振動(dòng)的能力較弱，在高速運(yùn)行時(shí)間較短，長(zhǎng)期使用也會(huì)發(fā)出較大的異常聲音。滾動(dòng)軸承和滑動(dòng)軸承的另一個(gè)本質(zhì)區(qū)別是滾動(dòng)軸承是表面接觸，而滑動(dòng)鎮(zhèn)江NSK軸承是點(diǎn)接觸。滾動(dòng)軸承接觸面大，結(jié)構(gòu)簡(jiǎn)單，操作拆卸方便，對(duì)滑動(dòng)軸承的潤(rùn)滑要求高。

Zhenjiang NSK bearing is a kind of component, which is widely used in various fields. It is divided into many kinds according to its structure or type, and classifies common rolling bearings and sliding bearings according to their friction characteristics. Both of them are different. The friction resistance of rolling bearings is much smaller than that of sliding bearings. It has the advantages of fast start up and high efficiency. Compared with plain bearings, rolling bearing is a great advantage. But there are also drawbacks, that is, the larger size, so the ability to absorb vibration is weak, in high-speed running time is short, long-term use will also emit a larger abnormal sound. Another essential difference between rolling bearings and sliding bearings is that the rolling bearings are surface contact, while the sliding Zhenjiang NSK bearings are point contact. Rolling bearing has large contact surface, simple structure, convenient operation and disassembly, and high lubrication requirement for sliding bearings.

當(dāng)雙向推力球軸承在拆卸檢查后損壞時(shí)，可根據(jù)軸承的損壞程度來(lái)判斷故障和軸承損壞。

When the two-way thrust ball bearing is damaged after disassembly inspection, the fault and bearing damage can be judged according to the damage degree of the bearing.

在周期性波動(dòng)載荷下，內(nèi)外滾道表面發(fā)生周期性接觸應(yīng)力變化。當(dāng)應(yīng)力循環(huán)次數(shù)達(dá)到一定值時(shí)，疲勞剝落發(fā)生在軋制面或內(nèi)外滾道上。如果軸承載荷過(guò)大，則會(huì)加劇疲勞。此外，如果鎮(zhèn)江NSK軸承錯(cuò)位，軸彎曲，滾道就會(huì)脫落。軸承滾道的疲勞剝落會(huì)降低軸的工作精度，引起振動(dòng)和噪聲機(jī)理。

Under cyclic loading, periodic contact stress changes on the inner and outer raceway surfaces. When the number of stress cycles reaches a certain value, fatigue peeling occurs on the rolling surface or inside and outside raceway. If the bearing load is too large, it will aggravate fatigue. Besides, if the NSK bearing of Zhenjiang is misplaced and the shaft is bent, the raceway will fall off. The fatigue peeling of the bearing raceway will reduce the working accuracy of the shaft and cause the vibration and noise mechanism.

燃燒軸承在滾道和滾動(dòng)體上有回火顏色。溫高通常是由于潤(rùn)滑不足，潤(rùn)滑不順或惡化，以及過(guò)度軸承裝配。

The combustion bearings have tempering colors on raceway and rolling body. High temperature is usually due to inadequate lubrication, poor lubrication or deterioration, and excessive bearing assembly.

鎮(zhèn)江NSK軸承滾道與接觸面的滾動(dòng)面之間出現(xiàn)凹痕，表明軸承存在塑性變形。其原因是，這通常發(fā)生在低速軸承在靜態(tài)或沖擊載荷下，其中工作表面上的局部應(yīng)力超過(guò)材料的屈服極限。

The dent between the NSK bearing raceway of Zhenjiang and the rolling surface of the contact surface indicates that the bearing has plastic deformation. The reason is that this usually occurs in low-speed bearings under static or impact loads, where the local stress on the working surface exceeds the yield limit of the material.

軸承套圈開(kāi)裂是造成軸承配合過(guò)大、內(nèi)外圈松動(dòng)、軸承座變形、軸承表面安裝和加工異常的主要原因。

Bearing ring cracking is the main reason for excessive bearing fit, loosening of inner and outer rings, bearing seat deformation, bearing surface installation and machining abnormalities.

其原因是潤(rùn)滑不足，滾動(dòng)體斷裂，閥座環(huán)歪斜等。

The reason is that the lubrication is insufficient, the rolling body is broken, the seat ring is skewed, etc.

可能的原因是滾子卡在籠子里或不夠潤(rùn)滑。

The possible reason is that rollers are stuck in cages or not lubricated enough.

可能是落在閥座上的異物、鎮(zhèn)江NSK軸承潤(rùn)滑油不足或潤(rùn)滑油水平不當(dāng)。

It may be a foreign object falling on the valve seat, insufficient lubricating oil in Zhenjiang NSK bearing or improper lubricating oil level.

載荷、潤(rùn)滑、裝配、環(huán)境條件、材料質(zhì)量或制造精度是影響雙向推力球軸承損壞的主要因素。

Load, lubrication, assembly, environmental conditions, material quality or manufacturing accuracy are the main factors affecting the damage of bi-directional thrust ball bearings.
