为了在机械使用中选择好的轴承,bi须对轴承有全.面而深刻的了解.一般来说,轴承是根据详细的机械或机械设备设计的.用户应根据所用设备的结构和尺寸选择合适的轴承尺寸.同时,必.须了解淮安SKF轴承所能承受的载荷.

In order to select good bearings in mechanical use, Bi must have a comprehensive and profound understanding of bearings. Generally speaking, bearings are designed according to detaiLED mechanical or mechanical equipment. Users should choose the appropriate bearing size according to the structure and size of the equipment used. At the same time, it is necessary to understand the load that Huaian SKF bearings can bear.

一般来说,轴承的选择bi须考虑zui大载荷的参数.轴承的主要功能是在一定负荷下工作.因此,在选择轴承时,应计算所需轴承设备能给轴承带来的zui大负荷.此时,可通过计算载荷来选择相应的轴承.这些基本因素是选择.一个好的轴承轮毂.

Generally speaking, the selection of bearing Bi must consider the parameters of Zui large load. The main function of bearings is to work under a certain load. Therefore, when choosing bearings, we should calculate the Zui heavy load that the required bearing equipment can bring to bearings. At this time, the corresponding bearing can be selected by calculating the load. These basic factors are choice. A good bearing hub.

选择轴承时需要考虑的一些因素是不同机器所需轴承的安装和拆卸困难.有些机器需要做一些紧急工作.因此,安装淮安SKF轴承更容易、更快.因此,应选择一些简单的轴承.同时,轴承寿命和材料质量也是一个关键因素.大型机械应选用寿命长、材质好的轴承.

Some factors that need to be considered when selecting bearings are the difficulty of installation and disassembly of bearings required by different machines. Some machines need to do some urgent work. Therefore, it is easier and faster to install Huaian SKF bearings. Therefore, some - bearings should be selected. At the same time, bearing life and material quality are also a key factor. Large-scale machinery should choose bearings with long service life and good material.

如何保证轴承在高温下正常工作?

How to ensure the normal operation of bearings at high temperature?

现代技术,如核动力系统、喷气发动机和燃气轮机,通常在数百到数千度的温度范围内运行.显然,普通进口轴承钢不能使用.bi须使用高温轴承钢或其余耐高温材料.一般认为,当温度超过120℃时,普通轴承钢的结构会发生变化,屈服强度会降低,精度会逐渐降低.当进口轴承的工作温度超过进口淮安SKF轴承材料的回火温度时,其硬度会显著降低.当工作温度超过180℃时,硬度急剧下降,很快就会发生早期疲劳磨损.保证进口轴承高温运行精度和使用寿命的关键是保证进口轴承在高温下具有足够的硬度、尺寸和形状稳定性.因此,对高温轴承钢提出以下要求:

Modern technologies, such as nuclear power systems, jet engines and gas turbines, usually operate at temperatures ranging from hundreds to thousands of degrees. Obviously, ordinary imported bearing steel can not be used. Bi shall be made of high temperature bearing steel or other high temperature resistant materials. It is generally believed that when the temperature exceeds 120 C, the structure of common bearing steel will change, the yield strength will decrease, and the accuracy will gradually decrease. When the working temperature of imported bearing exceeds the tempering temperature of imported Huaian SKF bearing material, its hardness will decrease significantly. When the working temperature exceeds 180 C, the hardness decreases sharply and early fatigue wear will occur soon. The key to ensure the high temperature operation accuracy and service life of imported bearings is to ensure that the imported bearings have sufficient hardness, size and shape stability at high temperature. Therefore, the following requirements are put forward for high temperature bearing steel:

1)高温硬度不低于HRC50-56,金相组织稳定.

1) Hardness at high temperature is no less than HRC50-56, and metallographic structure is stable.

2)尺寸稳定性好,热膨胀系数小,结构无明显变化,抗蠕变性能好,高温下残余应力低.

2) Good dimensional stability, small coefficient of thermal expansion, no obvious change in structure, good creep resistance and low residual stress at high temperature.

3)抗.氧化性好,氧化膜与基体结合力强,耐磨性和疲劳强度好,抗热震性好,能承受淮安SKF轴承快速的温度变化,导热性好;

3) Good oxidation resistance, strong adhesion between oxide film and matrix, good wear resistance and fatigue strength, good thermal shock resistance, can withstand the rapid temperature change of Huaian SKF bearing, good thermal conductivity;

4)进口轴承钢的其余材料性能.

4) The other material properties of imported bearing steel.
