一、引言ZX系列振动器的性能,主要可用振动频率,激振力和振幅等参数来体现。其中激振力、振幅确定后,随加工误差的大小变化不大,而振动频率则随零件加工误差而急剧改变。振动频率过低,不能有效地捣实混凝土,过高又可能因横板夹持松懈造成混凝土漏浆,所以振动频率的误差必须控制在一定范围内。影响振动器性能因素是多方面的,滚锥、滚道的加工质量虽然能影响振动器的性能,但只有在合理地确定振动器主要零件尺寸链公差 I. Introduction ZX series vibrator performance, the main available vibration frequency, excitation force and amplitude and other parameters to reflect. Exciting force, amplitude is determined, with the size of the error of processing little change, while the vibration frequency with the rapid changes in parts processing error. Vibration frequency is too low, can not effectively tamp concrete, too high and may be caused by horizontal plate slack caused by concrete leakage, so the vibration frequency error must be controlled within a certain range. The impact of vibrator performance factors are many, although the roller cone, raceway processing quality can affect the performance of the vibrator, but only in a reasonable way to determine the size of the vibrator main parts chain tolerance
