球轴承陀螺电机预载荷的影响分析

Analysis on the affection of pre-loaded ball bearing gyro-motor

在全面讨论预载荷对陀螺电机用精密角接触球轴承内部特性产生的变化和影响的基础上,研究分析了轴承预载荷对陀螺电机轴系刚度、摩擦力矩、寿命、转速、振动和噪音等性能的影响和作用。在充分考虑陀螺仪性能要求的前提下,提出了一种陀螺电机预载荷的确定方法,提高了陀螺电机预载荷确定的合理性。

On the basis of overall discussing the variation and influence produced by preloading on the interior characteristics of precision angle contact ball bearing used in gyro-motor, the enhancement and influence of performances on the rigidity of axle system of gyro-motor, frictional moment, life span, rotation speed, vibration and noise etc. affected by bearing pre-loading were studied and analyzed. Under the premise of considering sufficiently the performance requirements of gyroscope, a kind of method for determining the pre-loading of gyro-motor was put forward, and enhanced the determination rationality on the pre-loading of gyro-motor.
