Rotor balance experiment table

Abstract

The invention discloses a rotor balance experiment table which comprises a base, wherein at least two rotors are arranged on the base, each rotor is supported by a bearing, and all the bearings are mounted in a bearing block; the rotors are connected by a coupling, and driven by a motor through the coupling; a mounting hole for mounting an electrical vortex sensor is formed in the bearing block; a weighting disc for simulating an unbalance quantity is mounted on the rotors, strip-like through holes are evenly formed in the weighting disc in the radial direction, and weighting blocks for simulating the unbalance quantity are arranged to match with the strip-like through holes; besides, the strip-like through holes are evenly formed in the weighting disc of the unbalance quantity in the radial direction, and the weighting blocks for simulating the unbalance quantity are arranged to match with the strip-like through holes. The rotor balance experiment table is capable of reducing influence, caused by the experimental facility, on the unbalance quantity of the rotors, and improving the test precision of the unbalance quantity of the rotors.

Description

technical field [0001] The invention relates to a test bench in the field of vibration monitoring and control of rotating machinery, in particular to a rotor balance test bench, which can simulate the unbalanced forced vibration of a flexible rotor shafting system, effectively reproduce the unbalance phenomenon produced by a rotating machine, and is used for rotor dynamics. Research on balance theory and method. Background technique [0002] Imbalance is the most common failure of rotating machinery, and its handling is also the most complex of all failures. The balance methods for flexible rotor on-site dynamic balance can be classified into two categories: modal balance method and influence coefficient method. From the perspective of balance effect, although the above methods can achieve the ideal balance of the rotor, due to the diversity of flexible rotor structures Due to the complexity of the actual unbalance situation, at the same time, due to the strict limitations ...

AI Technical Summary

Problems solved by technology

[0009] In order to solve the problem that the rotor unbalance data obtained by the existing balance test bench is not accurate enough due to the influence of the experimental device itself, the present invention provides a rotor balance test bench, which can accurately and effectively obtain the simulated unbalance data of the rotor, and can obtain more A large amount of imbalance data reduces the influence of the experimental device on the experimental data and provides accurate theoretical data for the design, installation and commissioning of rotating equipment
