Abstract

The invention discloses an integral type disk shaft structure, and relates to the technical field of gas compressors. The integral type disk shaft structure comprises a first wheel disk (1), a second wheel disk (3) and an integral disk shaft (2), wherein the integral disk shat (2) comprises a shaft journal (21) and a third wheel disk (22), and the shaft journal (21) and the third wheel disk (22) are integrally shaped; the integral disk shaft (2) is fixedly connected with the first wheel disk (1) and the second wheel disk (3) through a connecting fitting. The integral type disk shaft structure disclosed by the invention has the beneficial effects that a conventional wheel disk and the shaft journal are processed into a whole, so that the axiality of the wheel disk and the shaft journal is guaranteed, and the rotation of the gas compressor is smooth.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an integral disk shaft structure. Background technique [0002] The disc and journal are important components in the compressor, and their concentricity seriously affects the vibration characteristics of the compressor rotor. The wheel disc and the journal of the conventional structure are fixed by the axial positioning of the end face, the radial positioning of the seam, and the axial connection of the bolt (see the schematic diagram of figure 1 ), the multi-channel spigot connection reduces the concentricity of the rotor, which is unfavorable to the vibration of the rotor. Therefore, a new wheel journal structure is urgently needed to improve the coaxiality between the wheel and the shaft diameter and improve its vibration characteristics. Contents of the invention [0003] It is an object of the present invention to provide a one-piece hub structure to solve or at leas...
