Dynamic balance compensation method of radial asymmetric rotor

Abstract

The invention relates to a dynamic balance compensation method for a rotor with an asymmetric radial structure. By integrating a left balance tool and a left balance frame as an integral component, the additional unbalance amount of a system is eliminated. A right balance tool and a right balance frame are integrated as an integral component, through the overturn compensation operation and staticbalance operation of the two integral components, the additional unbalance amounts of the right balance tool and a right balance frame system are eliminated, and thus the problem that the unbalance amount of each angular position of a rotor can not be corrected to a predetermined value for the rotor with asymmetrical radial structures at two ends is overcome. Through a method of eliminating the additional unbalance amount of the entire balance system by step operations, the problem of large fluctuation of the unbalance amount in the dynamic balance measurement of a rotor overturn angle can beeffectively overcome, and thus the dynamic balance work of the type of rotor can be completed with high quality.

Description

technical field [0001] The invention relates to a dynamic balance compensation method, in particular to a radial asymmetric rotor dynamic balance compensation method. Background technique [0002] For existing rotors that need to be flipped and compensated during dynamic balancing, the structures at both ends of the rotor connected to the balancing machine are radially symmetrical, that is, the radial structures at both ends of the rotor are either 180°symmetric, or 120°symmetric, or 90°symmetry, etc. When the rotor dynamic balance of this structure is used for overturn compensation operation, 180° overturn compensation, 120° overturn compensation, and 90° overturn compensation can be selected to meet the requirements. The compensation methods are generally: rotor, tooling and Preparation of equipment → installation of tooling and equipment → installation of tooling and rotor → first dynamic balance measurement → tooling rotates an angle (180°, 120°, 90°) relative to the rot...

Problems solved by technology

This process method is a mature and stable process method, and the on-site operation is relatively standardized. However, for the rotors whose two ends connected to the balancing machine are radially asymmetrical, such as the transmission shaft rotor in the helicopter transmission system, its One end is a triangular flange, and the other end is an even-numbered gear spline. When one end of the rotor is turned over with respect to the transfer tooling on this side during the compensation process, the other end cannot be rotated at the same angle relative to the other transfer tooling at the same time. , resulting in errors in the measurement of the balancing machine, unable to achieve correct compensation, and ultimately make the dynamic balance of the rotor fail
