Abstract

The invention discloses a cantilever centrifugal compressor which comprises a shell, a motor, an impeller driven by the motor to rotate, a transmission assembly and a lubricating oil way system symmetric about the vertical plane left and right. An output shaft of the motor is supported in the shell through two first bearings which are axially spaced. The transmission assembly is connected with the output shaft. A transmission shaft of the transmission assembly is supported in the shell through two second bearings which are axially spaced. The transmission shaft is sleeved with the impeller. The transmission shaft and the output shaft are located in the same vertical plane. The lubricating oil way system is arranged in the shell and used for lubricating the two first bearings and the two second bearings. According to the cantilever centrifugal compressor, the gravity center is located on the center plane, stability is high, the structure is compact, occupied space is small, the structure for supporting the shell is simple, the lubricating oil way system is simple, lubricating efficiency and reliability are high, the machining and assembling requirements of the transmission assembly are low, and cost is low.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a cantilever centrifugal compressor. Background technique [0002] It is pointed out in the related art that the structure of the traditional cantilever centrifugal compressor is not compact enough, takes up a large space, the center of gravity deviates from the center plane, the structure of the supporting shell is complicated, the lubricating oil circuit system is complicated, the efficiency is low, and the processing and assembly requirements of the transmission components are high. high cost. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the object of the present invention is to provide a cantilever centrifugal compressor, which has a compact structure, a small footprint, a simple lubricating oil circuit system, high lubrication efficiency, and low processing and ass...
