Abstract

A dynamic balance detection device with high transmission efficiency and expand-ability and a replaceable chuck step shaft as the rotating shaft is designed. It can be applied to the high-speed unbalance detection of micro impellers, which can eliminate transmission errors and prevent rotor turbulence. Reduce the function of supporting friction. Based on the research of impeller dynamic balance detection technology at home and abroad, combined with the theory of dynamic balance and the principle of dynamic balance detection device, a research program dedicated to the detection of micro-impeller dynamic balance is proposed, and the high-speed dynamic balance of small horizontal hard support for micro impeller is completed. The prototyping of the detection device and solving the key problems of the design of the measurement and control module and the data processing of the vibration detection. The dynamic balance test was carried out on a micro impeller with a dynamic balance of 1 μm, which verified the reliability and operability of the device. It is beneficial to the improvement of the dynamic balance precision of the rotating machine, which lays a foundation for the high-speed dynamic balance correction of the micro-impeller and provides a certain reference for engineering testing.
