在主机上安装淮安NSK轴承后，如果测量轴承主轴的径向跳动，可以发现每一个转动的测量值都有一定的变化；连续测量时，可以发现，经过一定的转动后，变化将近似重复。测量变化程度的指标是圆旋转的精度。重复旋转近似于循环旋转精度的准周期性。准周期变化范围大，即周期旋转精度差。
After installing the Huaian NSK bearing on the main engine, if the radial runout of the bearing spindle is measured, it can be found that the measured value of each rotation has a certain change; when continuously measuring, it can be found that after a certain rotation, the change will be approximately repeated. The index of measuring the degree of change is the accuracy of circular rotation. Repeated rotation approximates the quasi-periodicity of cyclic rotation accuracy. The range of quasi-periodic variation is large, that is, the precision of periodic rotation is poor.
如果对轴承主轴施加适当的预紧力，转速将逐渐提高，接近工作转速，从而实现轴承的“磨合”功能，提高主轴旋转精度。
If proper preloading force is applied to the bearing spindle, the speed will gradually increase, close to the working speed, thus realizing the "running-in" function of the bearing and improving the spindle rotation accuracy.
轴承安装后，为了检查安装是否正确，应进行操作检查。小型机器可以用手旋转以确保平稳旋转。淮安NSK轴承检查项目包括：***、伤痕、操作bu良造成的压痕、安装.bu良、力矩不稳定造成的安装座加工bu良、间隙过小、安装误差、力矩过大造成的密封摩擦等，如无异常，可启动供电运行。
After the bearing is installed, in order to check whether the installation is correct, the operation inspection should be carried out. ***all machines can be rotated by hand to ensure ***ooth rotation. Huaian NSK bearing inspection items include: foreign body, scar, indentation caused by operation Bu Liang, installation Bu Liang, installation seat processing Bu Liang caused by unstable moment, too ***all clearance, installation error, sealing friction caused by excessive moment, etc. If there is no abnormality, power supply operation can be started.
大型机械不能手动旋转。空载启动后立即切断电源。机器闲置。检查转动部件的振动、噪声和接触情况，确认无异常，进入动力运行。
Large machinery cannot rotate manually. Cut off the power supply immediately after no-load start-up. The machine is idle. Check the vibration, noise and contact of the rotating parts, confirm that there is no abnormality, and enter the power operation.
当电源运行时，空载、低速启动，并缓慢增加到规定的额定工作条件。在调试过程中，检查项目包括异常噪音、淮安NSK轴承温度变化、润滑油泄漏或变色。如果发现任何异常，应立即停止机器，必要时应拆下轴承进行检查。
When the power supply is running, no-load, low-speed start, and slowly increase to the specified rated working conditi***. During commissioning, the inspection items include abnormal noise, temperature change of Huaian NSK bearing, oil leakage or discoloration. If any abnormalities are found, the machine should be stopped immediately and the bearings should be removed for inspection if necessary.
轴承温度通常可以从轴承座的外部温度推断出来。但采用油孔直接测量轴承外圈温度更为准确。轴承温度从运行开始逐渐升高，通常在温度稳定后1至2小时。如果轴承安装不当，温度会急剧上升，出现异常高温。其原因包括润滑油过多、轴承间隙过小、安装.bu良、密封装置摩擦过大、轴承结构选择不当、润滑方式不合理等，也是高速旋转的原因。
Bearing temperature can usually be deduced from the external temperature of the bearing seat. But it is more accurate to use oil hole to measure the temperature of bearing outer ring directly. Bearing temperature gradually increases from the beginning of operation, usually 1 to 2 hours after temperature stabilization. If the bearing is not properly installed, the temperature will rise sharply and abnormal high temperature will occur. The reas*** include too much lubricating oil, too ***all bearing clearance, good installation. bu, too much friction of sealing device, improper selection of bearing structure, unreasonable lubrication mode and so on, which are also the reas*** for high-speed rotation.
***检测淮安NSK轴承的旋转声音。结果表明，金属噪声较大，声音异常。其原因包括润滑bu良、轴或轴承座精度差、轴承损坏、******等。
Stethoscope detects the rotating sound of Huaian NSK bearing. The results show that the metal noise is large and the sound is abnormal. The reas*** include good lubrication bu, poor precision of shaft or bearing seat, bearing damage, foreign body intrusion, etc.
