Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.

[0027] Take the dynamic unbalance of the impeller (high-speed rotor) controlled by the helicopter environmental control system as an example. The allowable unbalance of the rotor is 0.2g cm. When the remaining unbalance of the rotor is too large, it will cause the radial rotation of the rotor at high speed and cause Vibration can cause serious rotor failure.

[0028] Adopt dynamic balance processing method of the present invention to process, concrete implementation is as follows:

[0029] 1. Select equipment: select a dynamic balancing machine with good dynamics and stability. In this embodiment, select a dynamic balancing machine whose model is Pasio-50;

[0030] 2. Select the mandrel: such as figure 1 As shown, the mandrel adopts a counterweight structure, that is, a cylindrical counterweight. The...

Abstract

The invention discloses a method for removing unbalance of a high-speed rotor and a dynamic balancing mandrel. Under a hard support system, the mandrel and the rotor need to be dynamically balanced as a whole. The core shaft of the weighted block drives the rotor to rotate at high speed, and the rotor is weight-reduced to obtain the dynamic balance processing of the rotor. The invention can quickly and accurately measure the high-speed rotor and control its dynamic unbalance.

Description

technical field [0001] The invention relates to a dynamic balancing method for a high-speed rotating rotor, in particular to a dynamic balancing processing method for integral impeller train parts and high-speed rotor parts in the aviation field. Background technique [0002] With the development of science and technology, the performance of aeronautical machinery has been continuously improved. As an important component of aeronautical machinery, the rotor is developing in the direction of high speed and large aspect ratio. The working speed is often higher than the bending critical speed, and the structure is becoming more and more complex. Its dynamic characteristics have obvious characteristics, for example, it is very sensitive to the vibration caused by the unbalance, and the vibration caused by the unbalance of the high-speed rotor is one of the important reasons for the vibration of the whole machine. According to statistics, the failure of the equipment due to vibrat...
