Split type static pressure gas bearing device with adjustable swing angle and for rotor static balance

Abstract

The invention discloses a split type static pressure gas bearing device with an adjustable swing angle and for rotor static balance, and belongs to the field of rotor static balance detection. The split type static pressure gas bearing device with the adjustable swing angle and for rotor static balance is used for solving the problems that an existing rotor static balance device uses a rolling bearing as a support, due to the fact that the frictional resistance is high, rolling balls can be worn after the rolling bearing is used for a long time, the rotor measurement accuracy is reduced, and most of existing static pressure gas bearings are integrally manufactured and cannot be applied to the existing rotor static balance device. The split type static pressure gas bearing device with the adjustable swing angle and for rotor static balance comprises a bearing pedestal, an upper supporting base, a lower supporting base, a base and a gas inlet channel. A first semi-cylindrical face whichis inwards concave is processed on the bearing pedestal, and multiple gas holes are formed in the first semi-cylindrical face. The bearing pedestal is fixed to the upper supporting base, a sealed gascavity is formed between the bearing pedestal and the upper supporting base, the multiple gas holes communicate with the sealed gas cavity, and the sealed gas cavity is connected with an external gassupply device through the gas inlet channel. The upper supporting base and the lower supporting base are hinged so that the axis of the semi-cylindrical face can swing by a certain angle in the vertical direction. The lower supporting base and the base are connected together. The split type static pressure gas bearing device with the adjustable swing angle and for rotor static balance is suitablefor rotor static balance detection.

Description

technical field [0001] The invention relates to a bearing device, in particular to a split-type static pressure gas bearing device with adjustable swing angle for rotor static balance, belonging to the field of rotor static balance detection. Background technique [0002] In the process of manufacturing and installing rotor parts of rotating machinery, the rotor will produce unbalanced mass due to reasons such as material inhomogeneity, processing errors and assembly errors. During the rotation of the rotor, the unbalanced mass will cause the rotating machine to generate vibration and noise, seriously affecting the safety and reliability of the rotating machine. Therefore, all rotor parts of rotating machines need to be statically balanced. At present, rotor static balance detection devices usually use rotor static balance devices. [0003] The existing rotor static balancing device is provided with two sliding plates that can be adjusted up and down, and each sliding plate...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problem that the existing rotor static balance device adopts rolling bearings as support, due to the high frictional resistance, long-term use will cause the balls to wear out, resulting in a decrease in the measurement accuracy of the rotor. However, most of the existing static pressure gas bearings are integrally manufactured. Can not be applied to the problem of the existing rotor static balance device, and provide a split static pressure gas bearing device with adjustable swing angle for rotor static balance
