本文在高速气流纺杯轴承系统临界速度计算的基础上,通过在刚性支承与弹性支承状态下,芯轴振型与轴承受力的计算、分析、对比,从理论上对弹性支承减震器的作用实质作进一步的探讨。计算结果显示减震器改变了芯轴振型,改善了其疲劳磨损,大大降低了轴承受力的动态峰值,因而对改善轴承的润滑条件、减小摩擦磨损、降低功率消耗、提高轴承使用寿命有重要意义。 Based on the calculation of the critical speed of the high-speed rotor spinning bearing system and the calculation, analysis and comparison of the vibration mode and the bearing capacity under the conditions of rigid support and elastic support, The essence of action for further discussion. The calculation results show that the shock absorber changes the vibration mode of the mandrel and improves its fatigue wear, greatly reducing the dynamic peak value of the bearing stress, thereby improving the bearing lubrication conditions, reducing the friction and wear, reducing the power consumption and increasing the service life of the bearing There’s important meaning.
