Why do universal couplings need dynamic balancing

universal coupling

The universal coupling will produce unbalanced inertial force, centrifugal force and even dynamic deflection due to various reasons of the center of mass or the misalignment of the inertial main shaft and its axis of rotation, which is called rotor imbalance. This imbalance will inevitably lead to shaft vibration, thus affecting the normal operation and use of the machine, so we must pay attention to it.

In order to reduce the impact of this phenomenon as much as possible, the universal joint can improve this phenomenon by doing dynamic balancing. After the completion of product manufacturing and installation on the machine, on the specified balance or correction plane of the coupling, increase or decrease the appropriate quality to meet the balance level requirements. This process is called balance correction, or balance for short.
