转子不平衡能引起机器内另件的剧烈振动。这里介绍一种快速确定消除振动的平衡重位置的三步法。这种方法仅需要使用一个测振计或是一个过荷传感器就能保证选取的平衡重量和确定的位置的误差小于1%。确定最佳的平衡重量及其位置:1.把振动传感器安装到机器的适当位置上(通常在轴承上),使机器以某一速度转动并记录其振动大小,选定该读数为 a。2.把已知试验重量 m_1装到电动机半径为 r的地方,然后以相同的速度(同1)转动机器并记下振动大小。
Rotor imbalance can cause severe vibration of another piece of the machine. Here’s a three-step method to quickly determine the counterweight position to eliminate vibrations. This method only requires the use of a vibrometer or an overload sensor to ensure that the selected balance weight and the position of the error is less than 1%. Determining the Best Balance Weight and Its Position: 1. Mount the vibration sensor in the proper position on the machine (usually on the bearing), rotate the machine at a certain speed and record its vibration magnitude, selected as a. 2. Load the known test weight m_1 into the motor with a radius r and then turn the machine at the same speed (same as 1) and note the vibration level.
