A Method for Measuring Static Unbalance of Flexible Hollow Tube Shaft

ActiveCN103674429BAccurate measurementRealize measurementStatic/dynamic balance measurementEngineeringPotential energy
The invention relates to a method for measuring the unbalance amount of a flexible hollow shaft. According to the principle of minimum potential energy, balance mass is added to the flexible hollow shaft with static unbalance in the opposite direction of the mass eccentricity of the mass of the flexible hollow shaft, the balance mass is weighted when a tube is in the static balance state, and the original static unbalance amount can be calculated by multiplying the balance mass by the distance between the balance mass and the rotation center. According to the method, the static unbalance amount of the flexible hollow shaft can be accurately measured, the principle is simple, and the operation is convenient. After the method is used in practical production, measurement of the static unbalance amount of the flexible hollow shaft is successfully achieved.
