深溝球軸承安裝的好壞與否，將影曬深溝球軸承的精度、壽命和性能。因此，請充分硏究深溝球軸承的安裝，即請按照包含如下項目在內(nèi)的操作標(biāo)準(zhǔn)進(jìn)行深溝球軸承安裝。

 

　　The installation of deep groove ball bearings will affect the accuracy, life and performance of sundry deep groove ball bearings. Therefore, please fully study the installation of deep groove ball bearings, that is, the installation of deep groove ball bearings in accordance with the operating standards including the following items.

 

　　―、清洗深溝球軸承及相關(guān)零件（Cleaning deep groove ball bearings and related parts）

 

　　對已經(jīng)脂潤滑的深溝球軸承及雙側(cè)具油封或防塵蓋，密封圈深鯫 軸承安裝前無需清洗。

 

　　There is no need to clean the grease lubricated deep groove ball bearings and two sides with oil seals or dustproof covers.

 

　　二、檢查相關(guān)零件的尺寸及精加工情況（Two. Check the size and finishing of the relevant parts.）

 

　　三、安裝方法（Three. Installation method）

 

　　深溝球軸承的安裝應(yīng)根據(jù)深溝球軸承結(jié)構(gòu)，尺寸大小和深溝球軸承部件的配合性質(zhì)而定，壓力應(yīng)直接加在緊配合得套圈端面上，不得通過滾動體傳遞壓力，深溝球軸承安裝一般采用如下方法:

 

　　The installation of deep groove ball bearings should be based on the structure of deep groove ball bearings, size and the matching nature of deep groove ball bearing components. The pressure should be directly added to the end face of the tight fitting ring, and the pressure should not be passed through the rolling body. The following method is generally adopted in the installation of deep groove ball bearings.

 

　　a.壓入配合（A. pressure entry coordination）

 

　　深溝球軸承內(nèi)圈與軸使緊配合，外圈與深溝球軸承座孔是較松時，可用壓力機(jī)將深溝球軸承先壓裝在軸上，然后將軸連同深溝球軸承一起裝入深溝球軸承座孔內(nèi)，壓裝時在深溝球軸承內(nèi)圏端面上，墊一軟金屬材料做的裝配套管（銅或軟鋼），裝配套管的內(nèi)徑應(yīng)比軸頸直徑大，外徑直徑應(yīng)比深溝球軸承內(nèi)圈擋邊略小，以免壓在保持架上。深溝球軸承外圈與深溝球軸承座孔緊配合，內(nèi)圈與軸為較松配合時，可將深溝球軸承先壓入深溝球軸承座孔內(nèi)，這時裝配套管的外徑應(yīng)略小于座孔的直徑。如果深溝球軸承套圈與軸及座孔都緊配合時，安裝時內(nèi)圈和外圈要同時壓入軸和座孔，裝配套管的結(jié)構(gòu)應(yīng)能同時押緊深溝球軸承內(nèi)圈和外圈的端面。

 

　　The inner ring and shaft of the deep groove ball bearing are tightly matched. When the outer and deep groove ball bearing seat holes are loose, the deep groove ball bearing is first pressed on the shaft by the press, then the shaft is loaded with the deep groove ball bearing into the hole of the deep groove ball bearing seat, and the assembly sleeve is made of a soft metal material on the deep groove ball bearing. (copper or soft steel), the inner diameter of the assembly sleeve shall be larger than the Journal diameter, and the outer diameter shall be slightly smaller than the inner ring flange of the deep groove ball bearing to avoid pressure on the cage. Deep groove ball bearing outer ring and deep groove ball bearing seat tight matching, when the inner ring and shaft are loosely matched, the deep groove ball bearing can be pressed into the hole of the deep groove ball bearing seat first, and the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat. If the deep groove ball bearing ring is matched tightly with the shaft and the seat hole, the inner ring and the outer ring should be pressed into the shaft and the seat hole at the same time. The structure of the assembly sleeve should simultaneously tighten the end face of the inner ring of the deep groove ball bearing and the outer ring.

 

　　b.加熱配合（B. heating coordination）

 

　　通過加熱深溝球軸承或深溝球軸承座，利用熱膨脹將緊配合轉(zhuǎn)變?yōu)樗膳浜系陌惭b方法。是一種常用和省力的安裝方法。此法適于過盈量較大的深溝球軸承的安裝，熱裝前把深溝球軸承或可分離型深溝球軸承的套圏放入油箱中均勻加熱80-100℃,然后從油中取出盡快裝到軸上，為防止冷卻后內(nèi)圈端面和軸肩貼合不緊，深溝球軸承冷卻后可以再進(jìn)行軸向緊固。深溝球軸承外圏與輕金屬制的深溝球軸承座緊配合時，采用加熱深溝球軸承座的熱裝方法，可以避免配合面受到擦傷。用油箱加熱深溝球軸承時，在距箱底一定距離處應(yīng)有一網(wǎng)柵，或者用鉤子吊著深溝球軸承，深溝球軸承不能放到箱底上，以防沉雜質(zhì)進(jìn)入深溝球軸承內(nèi)或不均勻的加熱，油箱中必須有溫度計，嚴(yán)格控制油溫不得超過10CTC,以防止發(fā)生回火效應(yīng)，使套圏的硬度降低。

 

　　By heating the deep groove ball bearing or deep groove ball bearing block, the tight fit is transformed into a loose fit installation method by thermal expansion. It is a common and labor-saving installation method. This method is suitable for the installation of deep groove ball bearings with large interference amount. Before hot loading, the deep groove ball bearing or detachable deep groove ball bearings are evenly heated in the tank for 80-100 degrees, and then removed from the oil to the shaft as soon as possible to prevent the inner end of the inner ring and the shaft shoulder close after cooling, and the shaft of the deep groove ball bearing can be reacted again after the cooling of the shaft. Tighten. When the deep groove ball bearing is tightly matched with the deep groove ball bearing seat made of light metal, the heat loading method of the deep groove ball bearing seat can be used to avoid the abrasion of the matching surface. When heating deep groove ball bearings with the tank, there should be a net gate at a distance from the bottom of the box, or the deep groove ball bearing is suspended with a hook. The deep groove ball bearing can not be placed on the bottom of the box to prevent the impurities entering the deep groove ball bearing or uneven heating. The thermometer must have a thermometer in the tank, and the strict control of the oil temperature shall not exceed 10CTC. There is a tempering effect, which reduces the hardness of the sleeve.

　　C.圓錐孔深溝球軸承的安裝（ C.Installation of deep groove ball bearing with conical hole）

 

　　圓錐孔深溝球軸承可以直接裝在有錐度的軸頸上，或裝載緊定套和退卸套的錐面上，其配合的松緊程度可用深溝球軸承徑向游隙減小量來衡量，因此，安裝前應(yīng)測量深溝球軸承徑向游隙，安裝過程中應(yīng)經(jīng)常測 量游隙以達(dá)到所需要的游隙減小量為止，安裝時一般采用鎖緊螺母安 裝，也可采用加熱安裝的方法。

 

　　The conical hole deep groove ball bearing can be directly mounted on the cone with a taper, or on the conical surface of the tight set and the retreating sleeve. The tightness of the match can be measured by the reduction of the radial clearance of the deep groove ball bearing. Therefore, the radial clearance of the deep groove ball bearing should be measured before installation, and the clearance should be measured frequently in the installation process to meet the needs. The clearance should be reduced to a minimum. When installing, the lock nut should be installed normally, and the heating installation method can also be used.

 

　　d.推力深溝球軸承的安裝（ d.Installation of thrust deep groove ball bearing）

 

　　推力深溝球軸承的軸圈與軸的配合一般為過渡配合，座圈與深溝球軸承座孔的配合一般為間隙配合，因此這種深溝球軸承較易安裝，雙向推力深溝球軸承的中軸全應(yīng)在軸上固定，以防止相對于軸轉(zhuǎn)動。深溝球軸承的安裝方法，一般情況下是軸旋轉(zhuǎn)的情況居多，因此內(nèi)圈和軸的配合為過盈配合，深溝球軸承的外圈與深溝球軸承是的配合為間隙配合。

 

　　The coordination of shaft ring and shaft of thrust deep groove ball bearing is generally transition. The coordination of seat ring and deep groove ball bearing seat hole is usually clearance coordination, so this kind of deep groove ball bearing is easy to install, and the middle axis of the ball bearing of double direction thrust deep groove ball bearing should be fixed on the axis to prevent the rotation of the shaft relative to the shaft. The installation method of deep groove ball bearing, in general, is the majority of the axis rotation, so the coordination of the inner ring and the shaft is interference fit, the outer ring of the deep groove ball bearing and the deep groove ball bearing is the coordination of the gap.
