Abstract
Background: With the development of high-speed and high-precision rotating machinery, the rotor usually needs to work at very high speeds and the huge unbalancing vibration of rotor may be caused by a tiny unbalancing mass. To reduce the unbalance of rotor, a suitable dynamic balancing method should be designed for different rotor systems. In this article, various patents have been discussed.
Objective: The typical dynamic balancing methods and technologies are summarized and analyzed so as to provide some references for dynamic balancing design and application.
Method: To make it easier to design the proper balancing measure for actual rotating mechanical system, the dynamic balancing methods for rotor are classified as workpiece dynamic balance, assembling dynamic balance, field dynamic balance and online dynamic balance according to the balancing time of rotor.
Results: The principle of all kinds of dynamic balancing method is given firstly, and then advantages, disadvantages and future developments about each balancing method are reviewed in the paper.
Conclusion: Corresponding to these balancing methods, the online dynamic balancing method is recommended.
Keywords: Device, dynamic balance, method, patent, research, rotor.
