| 摘 要： | 设计了一种轴向支承电机转子的超声波悬浮支撑结构。采用圆锥型轴承超声悬浮支撑结构,并对承载能力进行了分析和测试,获得了悬浮力与悬浮间隙间的关系,在振动过程中形成稳定的承载气膜;从理论上分析了在超声悬浮支承条件下,悬浮间隙变化对于电机转子临界转速与振动模态的影响情况,对转子最高转速与悬浮间隙的关系进行了实验研究。结果表明,通过减小悬浮间隙,能增强间隙气膜的刚度支承效果,并提高转子的最高转速。

| Abstract: | A ultrasonic levitation support structure for axial support motor rotor is designed in this paper. The cone type bearing suspended support structure was used and the hosted capacity was analyzed and tested. The relationship between the suspension force and the suspension clearance has been obtained. The hosted gas film was formed in the vibration process. The effect of the suspension clearance change on the critical speed and vibration mode of the motor rotor was analyzed theoretically. The experimental study on the relationship between the maximum speed of revolution and the suspension clearance was carried out. The results have shown that the stiffness support effect of the gas film can be enhanced by reducing the suspension clearance and increase the maximum speed of revolution. |
