圓錐孔軸承可以直接安裝在錐形軸頸上,也可以用緊定套拆卸套作為中介,安裝在圓柱形軸頸上,但是不論在何種情況下,圓錐孔內圈的過盈量可根據SKF軸承游隙的減小量來測定。

Tapered bore bearings can be mounted directly on the tapered journal, or can be mounted on the cylindrical journal with the tightening sleeve removal sleeve as an intermediary, but in any case, the interference of the inner ring of the tapered bore can be measured according to the reduction of the clearance of SKF bearings.
徑向游隙減小量即SKF軸承在安裝前和安裝后的徑向游隙之差。在安裝前先要測知SKF軸承的原始徑向游隙,安裝時要頻頻測量游隙,直至達到與理想的過盈量相對應的徑向游隙減小量
The reduction of radial clearance is the difference between the radial clearance of SKF bearing before installation and after installation. The original radial clearance of SKF bearings should be measured before installation, and the clearance should be measured frequently during installation until the reduction of radial clearance corresponding to the ideal interference is achieved.
徑向游隙減小量的測量也可用SKF軸承在錐形軸頸上的推進量的測量來代替。對于1:12的標準錐度,徑向游隙減小量約相當于軸向推進量的1/15,在此比例下,對于實心軸而言,配合面的過盈量只有75%——85%起到使內圈擴張的作用。
The measurement of radial clearance reduction can also be replaced by the measurement of the thrust of the SKF bearing on the conical journal. For the 1:12 standard taper, the radial clearance reduction is about 1/15 of the axial thrust, in this ratio, for the solid shaft, only 75%-85% interference of the mating surface plays the role of expanding the inner ring.
大型球面滾子SKF軸承和圓柱滾子軸承的徑向游隙減小量通常用塞尺測量,注意對球面滾子SKF軸承必須分別從兩個端面測量兩列滾子處的徑向游隙,只有兩列滾子處的游隙值相同時,才能保證內圈與外圈相對正。
The radial clearance reduction of large spherical roller SKF bearings and cylindrical roller bearings is usually measured with a plunger. It should be noted that the radial clearance at two rows of roller must be measured from two end faces for spherical roller SKF bearings. only when the clearance values at two rows of roller are the same can the inner ring and outer ring be relatively positive.
小型的圓錐孔SKF軸承因其徑向游隙太小而不能使用塞尺測量,可用千分表接觸軸或SKF軸承座來測量推進時的提升量,此時注重的是徑向游隙量的變化,對滾動體和滾道的彈性變形就不加考慮了,推動SKF軸承或軸承座時所用的力,與它們的重量應大致相當。
Small tapered hole SKF bearings can not be measured with a plug because of their small radial clearance. They can be measured with a dial contact shaft or SKF bearing pedestal. At this point, the change of radial clearance is emphasized, and the elastic deformation of the roller and raceway is neglected. The force used to propel the SKF bearing or bearing pedestal is ignored. They should be roughly equivalent to their weight.
大型SKF軸承在裝進拆卸套時,,既可大大省力,又特別適合于地位受限制不能使用大的鉤扳手的場合。具體操作是:將淬硬的襯墊S置于拆卸套的端部,將螺母M輕輕旋緊,再將沿圓周均布的淬硬螺栓K均勻地擰緊,直至獲得所需的游隙減小量。由于拆卸套靠其錐形面的摩擦而自鎖,所以即使取下壓緊裝置也不致松脫,這樣可以放心地取下壓緊螺母M,改用固定螺母來代替,而將拆卸套壓緊。
Large SKF bearings can save a lot of labor when loading and disassembling sleeves, and are especially suitable for the occasions where large hook wrenches can not be used when the position is limited. The specific operation is: the hardened gasket S is placed at the end of the disassembly sleeve, the nut M is gently tightened, and then the hardened bolt K distributed uniformly along the circumference is tightened evenly until the required clearance reduction is achieved. Because the removal sleeve is self-locking due to friction on its conical surface, even if the compression device is removed, the compression nut M can be safely removed, replaced by a fixed nut, and the removal sleeve can be compressed.
在安裝時必須在退卸套的配合面上涂上極薄一層潤滑油,以減少摩擦,方便安裝。但注意絕不可涂油較厚,否則會使拆卸套失去自鎖能力,當取下壓緊螺釘和螺母以換裝固定螺母時,拆卸套會隨之松動而偏離調定位置,造成安裝失誤。
In order to reduce friction and facilitate installation, a thin layer of lubricating oil must be applied on the mating surface of the back-off sleeve. Nevertheless, it must not be coated with thick oil, otherwise the disassembly sleeve will lose its self-locking ability. When the compression screw and nut are removed to replace the fixed nut, the disassembly sleeve will loose and deviate from the adjusting position, resulting in installation errors.
此外,在工作過程中潤滑劑會逐漸從配合縫隙中被擠出或逸出,致使SKF軸承原先的過盈配合變得松動。
In addition, lubricant will gradually be extruded or escaped from the mating gap during the working process, resulting in the original interference fit of SKF bearing become loose.
當拆下已裝SKF軸承再將其安裝于軸頸時,不能照原樣地將螺母擰至原位,因為SKF軸承系統(tǒng)經過長時間工作以后,原配合已變松,這是由于螺紋漸漸松動,配合面受壓而有一定永久變形,并因摩擦而有一定磨損的原因。在此情況下,必須在安裝時重新測量其徑向游隙減小量、軸向推進量或擴張值。
When the SKF bearing is removed and installed in the journal, the nut can not be screwed to its original position, because the SKF bearing system after a long period of work, the original fit has become loose, this is due to the gradual loosening of the thread, the contact surface pressure and a certain permanent deformation, and because of friction and wear. In this case, the radial clearance reduction, axial thrust or expansion must be re-measured during installation.
對于大型SKF軸承,如采用液壓安裝方法,安裝時省力而快捷,拆卸時更為方便。
For large SKF bearings, such as the use of hydraulic installation method, the installation of labor-saving and fast, more convenient disassembly.
對于所有標準的拆卸套和帶螺紋軸端還可使用活塞式液壓螺母將SKF軸承裝在錐形軸頸上,或將拆卸套壓入圓柱形軸頸的預定位置上?;钊揭簤郝菽傅臉嫵杉捌涔ぷ髟硎牵航柚謩佑捅猛ㄟ^高壓軟管將壓力油壓入油缸(螺母),油缸以其內螺紋固定在帶螺紋軸端上,活塞的外伸端推壓在SKF軸承內圈的端面上,壓力油驅動活塞將SKF軸承推著沿錐形軸頸前進,根據管道中的油壓表的壓力,可以大致判斷SKF軸承的推進量。
For all standard removal sleeves and threaded shaft ends, SKF bearings can also be mounted on tapered journals using piston hydraulic nuts, or the removal sleeves can be pressed into cylindrical journals in a pre-positioned position. The composition and working principle of the piston hydraulic nut are as follows: the pressure oil is pressed into the cylinder (nut) by means of a manual oil pump through a high-pressure hose, the cylinder is fixed on the end of the shaft with a thread by its internal thread, the piston's extension end is pushed on the end surface of the SKF bearing inner ring, and the pressure oil drives the piston to push the SKF bearing forward along the tapered journal, and the root is pushed forward. According to the pressure of the oil pressure gauge in the pipeline, the propulsion amount of the SKF bearing can be roughly judged.
對于富有經驗的SKF軸承安裝人員而言,用手試轉SKF軸承以感知其運轉靈活性,也可控制SKF軸承的過盈量而不需用儀表測量,這對于小型的圓錐孔軸承的安裝尤其是這樣,但要經過嚴格考驗確有把握時才可實行,并且不得有萬一的疏忽。
For experienced SKF bearings installers, manually rotating SKF bearings to perceive their operational flexibility can also control the interference of SKF bearings without instrumentation. This is especially true for the installation of small tapered bore bearings, but it can only be carried out after rigorous testing and assurance, and must not be in case Negligence.
