Abstract

The invention discloses an ultra-precision dynamic balancing device applicable to a micro rotor, which comprises a device fixing portion, a rotor supporting bracket portion, a rotor driving mechanism portion and an unbalanced vibration monitoring portion, and is characterized in that a supporting bracket fixing frame of the device fixing portion can slide on a guide rail, and a base for installing the guide rail is fixed on a bottom plate; the rotor supporting bracket portion can realize amplification for weak unbalanced vibration, and can be divided into two types of supporting structure forms according to different vibration amplifying scales; a motor of the rotor driving mechanism portion can drive an unbalanced rotor to rotate in a belt driving mode; and the unbalanced vibration monitoring portion acquires the unbalanced vibration amplitude and the unbalanced vibration phase of the rotor through a displacement sensor and a phase. Compared with a traditional dynamic balancing device, the device disclosed by the invention is simple in structure, small in size, high in measurement precision for the weak unbalanced vibration, and more applicable to ultra-precision dynamic balance of the micro rotor.

Description

technical field

[0001] The invention relates to a rotor dynamic balance device, in particular to an ultra-precise dynamic balance device suitable for micro rotors. Background technique

[0002] Unbalance is the main factor that causes the vibration of rotating equipment. Small unbalance at high speed can also cause severe vibration. Only by controlling the residual unbalance of the rotor within a small range can the safe and reliable operation of rotating equipment be guaranteed. For this reason, domestic and foreign enterprises and research institutes have carried out many years of research on how to dynamically balance the rotor, and have achieved good dynamic balance results. However, with the development of industrial technology, industrial products are increasingly miniaturized and refined, and new requirements are put forward for the processing and testing performance of key components.

[0003] At present, most of the traditional dynamic balancing machines used in th...
