Technology Research and Application of Dynamic Balance for Shaftless Propeller Rotor
Due to errors in paddle blade machining,the mass center of a shaftless propeller rotor will not coincide with the central axis of that,which will result in mechanical vibration of the motor operating at the rated condition,and even will lead to danger and irregularity in severe case.This paper takes a shaftless propeller rotor as an example to summarize the mutual influence of the dynamic unbalance vector of the propeller rotor between the two end calibration faces,which should be calculated through vector synthesis to meet the balance accuracy requirements.This paper carries out the design of an auxiliary tools for dynamic balance of the shaftless propel-ler rotor,and researches a process method to achieve balance by material replacement in situation where weight cannot be removed,which can provide the reference for peer.
