A Dynamic Balance Compensation Method for Radially Asymmetrical Rotor

Abstract

The invention relates to a dynamic balance compensation method for a rotor with an asymmetrical radial structure, which eliminates the additional unbalance of the system by integrating the left balance tool and the left balance pendulum; As an integral component, the additional unbalance of the right balance tooling and the right balance pendulum system is eliminated through the flipping compensation operation and static balance operation of the two integral components, so as to overcome the asymmetrical rotor with radial structure at both ends, which cannot be The problem of correcting the unbalance of each angular position of the rotor to the specified value. The invention provides a method for eliminating the additional unbalance of the entire balance system through step-by-step operations, which can effectively overcome the large fluctuation of the unbalance during the dynamic balance measurement of the rotor turning angle problems, so as to complete the dynamic balancing work of this type of rotor 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
