摘要
在ROMAX中建立轴承-转子系统,根据轴承-转子基本参数及其承受不同振动加速度下得到轴承不同的工况和轴承游隙与寿命的关系。依据ISO16281修正参考额定寿命的计算公式,得到在不同工况下轴承的寿命,并考虑了配合及温度对轴承游隙影响。因此,依据配合及温度的影响,非驱动端初始径向游隙30~50μm,驱动端初始径向游隙45~75μm。
In the ROMAX to establish the bearing - rotor system, according to the basic parameters ofbearing - rotor and bear different vibration acceleration under different bearing conditions and bearingclearance and life relationship. According to IS016281 revised reference to the rated life of theformula, the bearing life under different conditions, and take into account the cooperation andtemperature on the impact of bearing clearance. Therefore, according to the coordination andtemperature, the initial radial clearance of the non-drive end is from 30 to 50 μm, and the initialradial clearance of the drive end is from 45 to 75 μm.
