Turbine rotor for low pressure turbomachine e.g. turbojet of aircraft, has upstream and downstream disks arranged coaxially, and bearing unit supporting end portion of flange to prevent deviation of flange of downstream disk

摘要

The rotor has an upstream disk (212) and a downstream disk (213) arranged coaxially and connected together by a flange (218). The disks carry blades (214) whose feet are engaged in grooves that are formed in the periphery of the disks. An annular flange (222) is mounted between the disks and around the flange for axial retention of the blades mounted on the downstream disk. A radial bearing unit (252) supports a downstream end portion of the flange of the downstream disk to prevent deviation of the flange of the downstream disk during operation.
