很多人在安裝NSK軸承中使用不當(dāng)?shù)陌惭b方法,導(dǎo)致軸承的損壞。那么如何正確的安裝NSK軸承呢?希望大家更全面的了解軸承的安裝與拆卸:
Many people use improper installation methods in the installation of NSK bearings, resulting in bearing damage. Then how to install NSK bearings correctly? I hope you will have a better understanding of the installation and disassembly of bearings.
安裝時(shí),可以根據(jù)其類型和尺寸,選擇機(jī)械、加熱或液壓等方法進(jìn)行。但在任何情況下,都不可以直接敲擊軸承圈、保持架、滾動(dòng)體或密封件。安裝時(shí)對(duì)軸承施加的作用力,絕不可通過(guò)滾動(dòng)體從一個(gè)軸承圈傳遞到另一個(gè)軸承圈,否則可能會(huì)對(duì)滾道造成損壞。
During installation, mechanical, heating or hydraulic methods can be selected according to its type and size. However, under any circumstances, the bearing rings, cage, rollers or seals can not be struck directly. The force exerted on the bearing during installation must not be transferred from one bearing ring to another through the rolling element, otherwise the raceway may be damaged.
對(duì)于間隙配合的軸承圈,建議在配合面涂一層薄薄的防蠕動(dòng)腐蝕劑,以防配合面之間產(chǎn)生摩擦腐蝕。
For the bearing rings with clearance fit, it is suggested to coat a thin layer of anti-creep corrosion agent on the mating surface to prevent friction corrosion between mating surfaces.
正確的安裝,對(duì)于NSK軸承的使用來(lái)說(shuō)是非常重要的。希望大家能夠在以后的使用中使用正確的安裝方法。
The correct installation is very important for the use of NSK bearings. I hope you can use the correct installation method in future use.
390000系列外球面軸承是通過(guò)偏心套將軸承內(nèi)圈與軸固定,偏心套上的內(nèi)六角螺釘起緊固作用。在維修中,不少機(jī)手不會(huì)拆裝這種NSK軸承,故有必要介紹一下拆裝390000系列外球面軸承的技術(shù)要點(diǎn)和注意事項(xiàng):
Series 390000 external spherical bearings fix the inner ring of the bearing to the shaft through an eccentric sleeve, and the inner hexagonal screw on the eccentric sleeve acts as a fastener. In the course of maintenance, many operators will not disassemble and assemble this kind of NSK bearing, so it is necessary to introduce the technical points and precautions for disassembling and assembling 390000 series external spherical bearings.
一、拆卸
One, dismantling
1.先用內(nèi)六角扳手松開(kāi)軸承偏心套上的鎖緊螺釘,然后用小鐵棒插入頂蓋偏心套上的沉孔,逆著軸的旋轉(zhuǎn)方向打松偏心套。
1. First loosen the locking screw on the eccentric sleeve of the bearing with an inner hexagonal wrench, then insert a small iron rod into the sunken hole on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the rotation direction of the shaft.
2.旋松固定軸承座的螺栓。將軸承連同軸承座一起從軸上卸下。注意在拆軸一端的軸承座之前.應(yīng)將軸另一端的軸承座螺栓松開(kāi),以免兩端軸承相互別勁而損壞。
2. loosening bolts for fixing bearing blocks. Remove the bearing from the shaft together with the bearing block. Note that before removing the bearing seat at one end of the shaft, the bearing seat bolts at the other end of the shaft should be loosened so as to avoid damage to the bearing at both ends.
二、安裝
Two. Installation
1.往軸上安裝進(jìn)口軸承前,必須先拔下軸承外套的固定銷,同時(shí)將軸頸表面打磨光滑干凈,并在軸頸處涂油防銹兼潤(rùn)滑(允許軸承在軸上有稍微轉(zhuǎn)動(dòng))。
1. Before installing the imported bearing on the shaft, the fixed pin of the bearing coat must be pulled out, and the surface of the journal must be polished smoothly and cleanly, and the journal should be oiled to prevent rust and lubricate (allowing the bearing to rotate slightly on the shaft).
2.在軸承座與軸承配合面涂潤(rùn)滑油,把軸承裝入軸承座內(nèi)。然后將裝配好的軸承與NSK軸承座一起套在軸上.推至所需位置處進(jìn)行安裝。
2. lubricating oil is placed on the mating surface of the bearing block and the bearing, and the bearing is loaded into the bearing seat. Then the assembled bearings are sleeved on the shaft with the NSK bearing seat and pushed to the desired location for installation.
3.固定軸承座的螺栓先不要擰緊,要讓軸承外套在軸承座內(nèi)能轉(zhuǎn)動(dòng)。同樣裝好同一根軸上的另一端軸承和座,將軸轉(zhuǎn)動(dòng)幾圈,讓軸承本身自動(dòng)找正位置后。再將軸承座螺栓緊固好。
3. the bolt of the fixed bearing seat should not be tightened first, so that the bearing sleeve can be rotated in the bearing seat. Similarly, the bearing and seat on the other end of the same shaft are installed, and the shaft is rotated several times, so that the bearing itself can find the correct position automatically. Then fasten the bearing seat bolts.
4.裝偏心套。先將偏心套套在軸承內(nèi)套的偏心臺(tái)階上,并用手順軸的旋轉(zhuǎn)方向擰緊.然后再將小鐵棍插入或頂住偏心套上的沉孔.用手錘順軸的旋轉(zhuǎn)方向敲擊小鐵棍.使偏心套安裝牢固,后鎖緊偏心套上的內(nèi)六角螺釘。
4. install eccentric sleeve. Firstly, the eccentric sleeve is put on the eccentric step of the bearing inner sleeve, and is tightened with the rotation direction of the hand in the axial direction. Then, the small iron rod is inserted into or against the hole of the eccentric sleeve. The small iron rod is knocked with the rotary direction of the hand hammer in the axial direction. The eccentric sleeve is fixed firmly, and the inner hexagonal screw on the eccentric sleeve is finally locked.
