Online dynamic balance head of liquid type high-speed rotor and technological embodiment thereof

Abstract

The invention relates to an online dynamic balance head of a liquid type high-speed rotor and a technological embodiment thereof. The online dynamic balance head comprises a balance head body (2), seal rings (4), a micro peristaltic pump (5), hoses, a bolt, a motor (18), a front end cover (22), a rear end cover (12), an air exhaust joint (23), a battery pack (19), and a detection and control system; the balance head body (2) is fastened with a rotor shaft (1) through a third screw (16), and the end face of the balance head body (2) is provided with four or more liquid storage chambers (3) which are arranged in a central symmetry manner and are consistent in size; water or other liquid of which the volume accounts for half that of the volume of each liquid storage chamber (3) is filled into each liquid storage chamber (3), and two opposite liquid storage chambers (3) are communicated through hoses by means of the micro peristaltic pump (5) capable of working in a bidirectional and leakless manner; and each seal ring (4) is located in a fifth groove (25) on the periphery of each liquid storage chamber (3). In the invention, the micro peristaltic pump (5) is used for precisely regulating and balancing weight distribution in a plane to realize online dynamic balance, and the online dynamic balance head has the characteristics of simple structure, fast response, high precision, wide application prospect and the like.

Description

technical field [0001] The invention relates to an online dynamic balancing head for a rotor, in particular to an online dynamic balancing head for a liquid-type high-speed rotor. Background technique [0002] High-speed rotor is one of the most critical components in high-speed rotating machinery, especially in high-speed processing machine tools. Its rotation accuracy has a crucial impact on the processing performance and reliability of the entire machine tool. During the manufacturing and assembly process of high-speed rotors, the center of mass and the center of rotation will inevitably be inconsistent due to uneven material, processing and assembly errors, etc. In this way, when the rotor rotates at a high speed, a dynamic imbalance will occur. The dynamic unbalance of rotor rotation is one of the main causes of machine tool vibration, noise, bearing heating and other phenomena. The higher the rotor speed, the greater the adverse effects caused by unbalance. In orde...

AI Technical Summary

Problems solved by technology

The balance head has a complex structure and a large volume, and is not suitable for high-speed rotors

[0009] It can be seen that the existing various rotor online dynamic balancing devices and technologies have more or less problems such as low balancing accuracy, complex structure, high cost, inconvenient energy supply, poor environmental compatibility, and not suitable for high-speed rotors, etc. insufficient

These have seriously restricted the further development of high-speed rotor applications
