高低速軸承一般是以線速度而不是轉(zhuǎn)速來定位的

 

　　High and low speed bearings are usually positioned by linear speed rather than speed.

 

　　高速軸承的速度都要達(dá)到每秒60米以上的速度要求，所以小軸承可能隨便都是幾萬轉(zhuǎn)，但是也不是高速軸承，而超大軸承每分鐘幾百轉(zhuǎn)就算高速軸承了，原因就是后者線速度大。在滑動(dòng)軸承中，液體靜壓軸承、液體動(dòng)壓軸承、氣體靜壓軸承、氣體動(dòng)壓軸承都適合高速旋轉(zhuǎn)。

 

　　High-speed bearings have to reach the speed of more than 60 meters per second, so small bearings may be tens of thousands of revolutions, but not high-speed bearings, and super-large bearings every minute hundreds of revolutions even high-speed bearings, the reason is that the latter linear speed. In sliding bearings, hydrostatic bearings, hydrodynamic bearings, aerostatic bearings, aerodynamic bearings are suitable for high-speed rotation.

 

 

　　Low speed general rolling bearings, high speed plain sliding bearings.

 

　　顧名思義，滾動(dòng)軸承里有滾珠，有球形的，圓柱形的，圓錐形的?；瑒?dòng)軸承里一般是軸瓦。高低速軸承通過外觀很難辨別，而且常見的低速軸承居多且價(jià)格便宜，但在機(jī)械內(nèi)部?jī)?nèi)使用的高速軸承較多。

 

　　As the name suggests, rolling bearings have balls, spherical, cylindrical, conical. Plain bearings are usually bearing bushes. It is difficult to distinguish high-speed bearings from low-speed bearings by their appearance, and the common low-speed bearings are more and cheaper, but the high-speed bearings used in the internal machinery are more.

 

　　高速軸承一般使用于機(jī)器內(nèi)部用液體軸承油降溫潤(rùn)滑

 

　　High speed bearings are usually used in the machine to lubricate with liquid bearing oil.

 

　　如果軸承不是用在汽車上對(duì)于電機(jī)這種轉(zhuǎn)速高沒有多大力量的地方，高速軸承也可以用固體軸承油降溫潤(rùn)滑。一般發(fā)動(dòng)機(jī)變速器差速器內(nèi)部使用的就是高速軸承，而底盤如半軸輪轂軸承使用的就是低速軸承。

 

　　High-speed bearings can also be cooled and lubricated with solid bearing oil if the bearings are not used in automobiles where the high speed of the motor does not have much power. Generally speaking, high-speed bearings are used in engine transmission differential, while low-speed bearings are used in chassis such as semi-axle hub bearings.

 

　　如果一定要從外表去區(qū)分高低速軸承，可以看以下兩點(diǎn)：

 

　　If we must distinguish the high and low speed bearings from appearance, we can see the following two points:

 

　　1、高速軸承比低速軸承的精度高，而且它的表面粗糙度小。直觀區(qū)別就是高速軸承比低速軸承的表面更加光滑，晃動(dòng)外圈跟內(nèi)圈高速軸承的間隙更小，而低速的則相反。

 

　　1, high speed bearing is more accurate than low speed bearing, and its surface roughness is small. The visual difference is that the surface of high-speed bearings is smoother than that of low-speed bearings, and the clearance between the shaking outer ring and the inner ring of high-speed bearings is smaller than that of low-speed bearings.

 

　　2、高速軸承跟低速軸承相比，其軸承的鋼珠或滾子的精度不同，以及滾道的精度高于低速軸承的精度，高速軸承的等級(jí)高且材質(zhì)好，比如鋼材的金相組織，硬度等。

 

　　2. Compared with low-speed bearings, high-speed bearings have different ball or roller precision, and the accuracy of raceway is higher than that of low-speed bearings. High-speed bearings have high grade and good material quality, such as microstructure and hardness of steel.

 

　　一般的滾動(dòng)軸承適應(yīng)低中速度的旋轉(zhuǎn)，如果使用滾動(dòng)軸承高速旋轉(zhuǎn)需要特殊的要求，可以根據(jù)使用的載荷等因素合理選擇其型號(hào)。

 

　　General rolling bearings adapt to low and medium speed rotation, if the use of high-speed rolling bearings require special requirements, according to the use of load and other factors can reasonably choose its model.

 

　　如果速度在5到60米每秒之間的話就算不上高速軸承，一般的軸承只要能潤(rùn)滑基本都能滿足。如果在一些特殊的場(chǎng)合使用速度更高的軸承，比如在高速切削機(jī)床或者精密加工等機(jī)床使用的高速旋轉(zhuǎn)軸承還可以使用陶瓷軸承、電力、磁力軸承等特殊的軸承，就要與專業(yè)的廠家聯(lián)系。

 

　　If the speed is between 5 and 60 meters per second is not high-speed bearings, as long as the general bearing can be lubricated can basically meet. If the use of higher speed bearings in some special occasions, such as high-speed cutting machine tools or precision machining machine tools used in high-speed rotary bearings can also use ceramic bearings, electric power, magnetic bearings and other special bearings, it is necessary to contact professional manufacturers.
