When designing a new spindle, before selecting INA bearings, the spindle performance parameters should be considered first, the key performance should be roughly determined, and then the further probe should be carried out. (including: spindle speed, spindle accuracy, spindle rigidity, spindle life, spindle heating, spindle reliability)
Rolling bearing is a standard part, in the mechanical design, it is required to choose the rolling bearing correctly. First, select the type of bearing; Then according to the working conditions, use requirements and bearing characteristics of the corresponding calculation, and from the relevant national standards to select the appropriate model.
There are dozens of kinds of bearings on the car are rolling bearings, which almost include all the common bearing types, and the collision and damage of rolling bearings are also more common. Because the rolling bearing is generally installed in the mechanism, so it is not convenient for intuitive inspection, can only make a brief judgment according to the fault phenomenon, and then disassemble and check. The correct use of rolling bearings is a reliable guarantee to reduce bearing failure and extend bearing life, which includes correct installation and reasonable lubrication.
IKO bearing vibration is very sensitive to bearing damage, such as spallation, indentation, rust, crack, wear and so on will be reflected in the bearing vibration measurement, so the size of the vibration can be measured by using a special IKO bearing vibration tester (frequency analyzer, etc.), and the specific situation of the abnormal can not be inferred through the frequency division. The measured value is different due to the service conditions of bearings or the installation position of sensors, so it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.
