[0002] High-speed rotating machinery is greatly affected by materials. Impact, corrosion, wear, and coking can cause imbalance faults in the rotor system of the machine. 70% of the vibration faults of rotating machinery come from the imbalance of the rotor system. Usually, maintenance personnel dismantle the rotor with large vibration, directly replace the impeller, etc., and reinstall it to reduce the vibration. However, due to the original imbalance of the rotating parts, the vibration sometimes still exceeds the standard allowable value after the machine is running. In order to prevent the machine from being destroyed, threatening the safety of on-site personnel and ensuring the normal operation of production, dynamic balancing correction is required.
[0003] Since the size tolerance of the inner tooth of the flange is Φ68+0.035 / +0.005, and the size of the outer tooth of the tooling is Φ68+0 / -0.02, it is easy to cause difficulties in the docking and disengagement of parts and tooling, affecting the beat and efficiency. Therefore, a dynamic balancing flange connection fixing tensioning device is needed to solve the above problem. Utility Model Content
