Abstract

The invention discloses an air compressor rotor and relates to the technical field of air compressors. The air compressor rotor comprises rotor blades (1), rotor plates (2), a rotor shaft (3) and locking nuts (7). At least two rotor plates (2) are arranged. The rotor shaft (3) is sleeved with the fixing ends of the rotor plates (2). Blade installing ends are used for installing the rotor blades (1). An intermediary ring (4) is arranged between the blade installing ends of the two rotor plates (2) and makes contact with the two rotor plates (2) in the axial direction of the rotor shaft (3). The blade installing end of at least one rotor plate (2) is connected with the intermediary ring (4). The fixing ends of the multiple rotor plates (2) are fixed through the locking nuts (7) in the axial direction of the rotor shaft (3). The air compressor rotor has the advantages that the air compressor rotor comprises the multiple rotor plates, the rotor plates can be replaced and maintained individually, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor rotor. Background technique [0002] The connection of the compressor rotor mainly solves the problems of disk connection, disk shaft connection, blade and disk connection, etc. Disk connection and disk shaft connection can be divided into detachable and non-detachable. The detachable connection includes short bolt connection, long bolt connection, circular arc end tooth plus center tie rod connection and sleeve tooth connection; the non-detachable connection has two methods: pin connection and welding connection. There are three ways of connection between the blade and the disk: the overall blade disk, the axial tenon and the circumferential tenon. However, in the existing compressor rotors, the rotor disk is an integral structure. Whether it is detachable or non-detachable, as long as one part of the rotor disk is damaged, the entire rotor disk needs to be re...
