High-speed cantilever centrifugal compressor rotor mechanism

Abstract

This invention discloses a kind of high-speed cantalever leaves-away type rotor device of compressor machine, is mainly made up of a set of tube (housing), a set of lining, several bearings, one transmission shaft and an impellers, be suitable for the link of a equipment for power output. Among them, the sleeve have a first flank, a second flank, a central hole and several ring costal region, but the lining install to combine in the sleeve with a mutual coalescence of a ring rib, and the bearing install in the lining, and transmission shaft through these bearings, and carrying on to connect one turbine engine at one side of the transmission shaft, is the turbine engine coalescence with the second flank, another side link to the impeller, make impeller locate in the first flank, and arouse the transmission shaft to turn to move but connect to move the impeller through the power output machine.

Description

technical field [0001] The invention relates to a rotating mechanism, in particular to a high-speed cantilever centrifugal compressor rotor mechanism. Background technique [0002] In addition to using the built-in auxiliary power system of the general passenger plane or fighter jet engine activation, another option is to use an air source vehicle. The high-pressure air source provided by the air source vehicle is input into the air turbine in the engine of the airliner or fighter jet. The air turbine is driven by the high-pressure airflow to generate shaft work, which in turn drives the main shaft of the aircraft engine to above the ignition speed. At this time, the driver again The aircraft engine is ignited, and the air source vehicle completes the aircraft engine activation procedure at this moment. [0003] Therefore, the design purpose of the air source vehicle is to provide compressed air to reactivate the engine of the stopped aircraft, or when the engine is repaire...

AI Technical Summary

Problems solved by technology

[0007] 1. The impeller is placed between the ball bearing and the roller bearing. Therefore, when the impeller is rotating, the bearing lubricating oil is easy to seep into the compressed air. In addition to having a long-term adverse effect on the aircraft engine, it is more likely to cause oil drop pollution to the air in the cabin air conditioner , which threatens the health of passengers

[0008] 2. The rotating mechanism of conventional compressors lacks oil film damping or a damper, so it is not easy to solve the problem of mechanical vibration

[0009] 3. The operating speed of the roller bearing of the conventional compressor is limited and cannot be increased to the working speed (33000rpm)
