泰州INA轴承NKI75/25润滑下的精密安装运转

在维护泰州INA轴承双向推力球轴承时，过量的润滑脂会造成很大的危害。润滑脂具有良好的附着力、耐磨性、耐温性、防锈性和润滑性。提高耐高温氧化性，延缓老化，溶解积碳，防止金属屑和油污结块，提高耐磨性和耐磨性。嗯。耐药性。机械的耐腐蚀性和耐腐蚀性。

When maintaining the two-way thrust ball bearing of Taizhou INA bearing, excessive grease will cause great harm. Lubricating grease has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity. Improve high temperature oxidation resistance, delay aging, dissolve carbon deposition, prevent metal chips and oil pollution from caking, improve wear resistance and wear resistance. Uh huh. Drug resistance. Corrosion resistance and corrosion resistance of machinery.

润滑脂填充量越大，摩擦扭矩越大。在相同的填充量下，密封轴承的摩擦力矩大于开口轴承的摩擦力矩。当润滑脂填充量等于轴承内部空间体积的60个百分点时，摩擦力矩不会显著增加。这是因为大多数泰州INA轴承润滑脂是在开式轴承中挤出的，而润滑脂是在密封轴承中损失的。

The greater the grease filling, the greater the friction torque. Under the same filling amount, the friction moment of the sealed bearing is greater than that of the open bearing. When the grease filling is equal to 60% of the internal space volume of the bearing, the friction moment will not increase significantly. This is because most of Taizhou INA bearing grease is extruded in open-type bearings, and grease is lost in sealed bearings.

随着润滑脂填充量的增加，双向推力球轴承温升呈线性增加。在相同的填充率下，轴承的温度高于开口轴承的温度。一般来说，密封滚动泰州INA轴承的润滑脂填充能力**多不超过内部空间的50个百分点。Shawki和Mokhtar的试验表明，20个百分点-30个百分点的双向推力球轴承是**合适的。

With the increase of grease filling, the temperature rise of bi-directional thrust ball bearings increases linearly. At the same filling rate, the temperature of the bearing is higher than that of the open-end bearing. Generally speaking, the grease filling capacity of sealed rolling Taizhou INA bearings ** does not exceed 50 percentage points of the internal space. Shawki and Mokhtar tests show that 20 to 30 percentage points of bi-directional thrust ball bearings are ** suitable.

1)由于精*密轴承本身的精度小于1微米，因此与其配套零件(轴、轴承座、端盖、保持环等)具有高的尺寸和形状精度非常重要，尤其是控制其匹配面的精度。杠杆作用。与进口轴承一样，它也是**容易被忽视的。

1) Because the precision of precision bearing itself is less than 1 micron, it is very important to h***e high dimensional and shape accuracy with its matching parts (shaft, bearing seat, end cap, retaining ring, etc.), especially to control the accuracy of its matching surface. Leverage. Like imported bearings, it is also easily overlooked.

2)还**须指出，如果精*密轴承的零件不能满足上述要求，精*密轴承的误差往往在安装后出现几倍甚至10倍以上，这比原轴承的误差大。原来的轴承不是精*密轴承。铃响了。其原因是，匹配零件的误差不仅叠加在泰州INA轴承误差上，而且不叠加在轴承误差上。放大后添加相同的倍数。

2) It should also be pointed out that if the parts of precision bearing can not meet the above requirements, the error of precision bearing often occurs several times or even more than 10 times after installation, which is larger than the error of the original bearing. The original bearing is not precision bearing. The bell is ringing. The reason is that the error of matching parts is not only superimposed on the bearing error of Taizhou INA, but also not on the bearing error. Add the same multiples after zooming in.

建议将旋转环的点火干扰降低到较小的程度。只要在工作温度下保证热膨胀效应和**大离心力，紧密匹配的表面就不会蠕变或滑动。固定环根据工作负荷和轴承尺寸选择**小间隙配合或过盈配合。太松或太紧不利于保持原有精*确的形状。

It is suggested that the ignition interference of the rotating ring be reduced to a lesser extent. As long as the thermal expansion effect and ** large centrifugal force are guaranteed at working temperature, the tightly matched surfaces will not creep or slip. Fixed rings are selected with ** ***all clearance fit or interference fit according to workload and bearing size. Too loose or too tight is not conducive to maintaining the original precise shape.

为了提高进口轴承在安装中的实际匹配精度，**须采用不引起轴承变形的测量方法和测量工具，准确测量轴承内外孔的匹配表面尺寸。所有内外径测量项目均可测量，测量数据可综合评分。在此基础上，对泰州INA轴承座和座孔的尺寸进行了精*确匹配。当测量轴和座孔的相应尺寸和几何形状时，应在与测量轴承相同的温度下进行。

In order to improve the actual matching accuracy of imported bearings in installation,** it is necessary to adopt measuring methods and measuring tools that do not cause bearing deformation to accurately measure the matching surface dimensi*** of bearing inner and outer holes. All internal and external diameter measurement items can be measured, and the measured data can be scored comprehensively. On this basis, the dimensi*** of INA bearing seat and seat hole in Taizhou are accurately matched. When measuring the corresponding size and geometric shape of the shaft and seat hole, it should be carried out at the same temperature as measuring the bearing.
