【摘要】 介绍一种用动态性能试验法测试空载时在精密推台锯上的德国产锯片锯齿径向跳动值,以及旋转主轴振动情况。在用加速度计拾振的幅频曲线中,发现推台锯旋转主轴在基频时出现最大振动峰值,由此判断旋转主轴存在不平衡故障。更多还原

【Abstract】 Introducing a kind of dynamic capability study method which tested jumpiness of the sawblade made in Germany on the precision sizing saw machine, as well as vibration of principal rotation axle. In geted "A-F" curve chart by acceleration sensors response, discovered that principal rotation axle on this sizing saw machine appeared most vibration peak data when reached its basis frequence,thereout estimated that its principal rotation axle has imbalance fault.更多还原
