摘　　要：Modern rotating machines,which are represented by high-end grinding machines,have developed toward high precision,intelligence,and high durability in recent years.As the core components of grinding machine spindles,grinding wheels greatly affect the vibration level during operation.The unbalance vibration self-recovery regulation(UVSRR)system is proposed to suppress the vibration of grinding wheels during workpiece processing,eliminating or minimizing the imbalance.First,technical principles and the system composition are introduced.Second,the balancing actuator in the UVSRR system is analyzed in detail.The advanced nature of the improved structure is presented through structure introduction and advantage analysis.The performance of the balancing actuator is mutually verified by the theoretical calculation of torque and software simulation.Results show that the self-locking torque satisfies the actual demand,and the driving torque is increased by 1.73 times compared with the traditional structure.Finally,the engineering application value of the UVSRR system is verified by laboratory performance comparison and actual factory application.The balancing speed and effect of the UVSRR system are better than those of an international mainstream product and,the quality of the workpieces machined in the factory improved by 40%.
