Abstract

The invention provides an air cycle machine which comprises a compressor and a turbine, the compressor and the turbine share a rotating shaft, the air cycle machine further comprises a bearing seat assembly, the bearing seat assembly comprises a bearing seat, the bearing seat is arranged on the peripheral side of the rotating shaft in a sleeving mode, a first axial side of the bearing seat is connected with a compressor volute of the compressor, a second axial side of the bearing seat is connected with a turbine volute of the turbine, and a sealing piece is further arranged on the first axial side of the bearing seat. According to the air cycle machine, heat transfer between the compressor and the turbine can be effectively reduced, the heat insulation performance is improved, on the other hand, the middle section of the rotating shaft can be effectively supported, and the rotating reliability of the rotating shaft is guaranteed; meanwhile, the sealing piece is located on one side of the compressor, so that the sealing performance between the compressor and the turbine can be improved.

Description

Technical field [0001] The present invention belongs to the field of air conditioning technology, particularly relates to an air cycle machine. Background technique [0002] The air cycle machine by air cooling gas to achieve expansion of external work in a turbine, and drives the compressor and the fan rotation. Compressor, fan, the turbine is a typical three-based air cycle machine, which is characterized by three coaxial. The air flow flows along a next component, the air enters the compressor, through the booster compressor of the turbine raised to the next level, pass through the turbine gas expands to work, to achieve a decrease in temperature. In the related art, in order to prevent play between adjacent compressor and the gas turbine, is provided between the sealing plate, the sealing plate increases the resistance to gas flow, sealing, since the compressor and the turbine assembly is a adjacent components, compressor discharge temperature and high pressure gas, while the...
