Abstract

The present invention relates to a turbo compressor, and more particularly to a thrust plate assembly for a turbo compressor. The thrust disk assembly comprises a thrust plate and a rotating shaft, wherein the rotating shaft is a stepped shaft including a first stepped shaft, a second stepped shaft, and a third stepped shaft and a fourth stepped shaft. The thrust plate includes a main thrust plateand a secondary thrust plate, wherein the auxiliary thrust plate is located on the second stepped shaft, and the auxiliary thrust plate is integrally formed with the rotating shaft; the main thrust plate is located on the third stepped shaft and fixed with the rotating shaft through a screw, the third stepped shaft is further provided with a positioning collar, an annular retaining ring abuttingagainst the positioning collar, and the fourth stepped shaft is sleeved with a bearing. The thrust disc assembly can effectively solve the problem that the thrust plate is easy to wear and loose in the prior art. The assembly efficiency of a thrust plate assembly is improved, and the service life of the thrust plate assembly is prolonged.

Description

technical field [0001] The invention relates to a turbocompressor, in particular to a thrust disc assembly of a turbocompressor. Background technique [0002] The front and rear thrust plates of the turbo compressor are installed on the main shaft in the form of transition fit and are connected by keys. The installation and removal of the thrust plates is extremely inconvenient, and the contact surface between the thrust plate and the main shaft is easy to be damaged during installation and disassembly. , resulting in the scrapping of parts. If the front and rear thrust discs are connected to the main shaft by interference fit, the thrust discs need to be shrunk, which will easily lead to deformation of the thrust discs and fail to ensure the flatness of the thrust discs. If the front and rear thrust discs are connected to the main shaft with clearance fit, it is easy to cause the thrust discs to shake on the main shaft and increase the shaft vibration of the rotor.
