The invention provides a special magnetically conductive ring for a magnetic levitation type turbofan jet engine. The special magnetically conductive ring mainly and structurally comprises an ultrathin magnetically conductive ring body, wherein the outer diameter of the magnetically conductive ring body is smaller than that of a magnetic ring, and the inner diameter of the magnetically conductive ring body is smaller than that of the magnetic ring, namely, the inner diameter and outer diameter of the magnetically conductive ring are unequal.
Description
Technical field [0001] The invention relates to a special magnetic conduction ring for a magnetic levitation type turbofan aircraft engine, in particular to a magnetic conduction ring whose inner diameter is smaller than the inner diameter of a magnetic levitation bearing magnetic ring. It belongs to the field of new energy technology. Background technique [0002] In today's aircraft engines, when the main shaft rotates, an axial pressure of several tons to more than ten tons will be generated. This rotational pressure will be transmitted to the thrust bearing, which will generate huge noise and cause huge frictional heat at the same time. At this time, the aircraft The engine needs to be equipped with a lubrication system to dissipate the heat generated by huge friction. In this way, the aircraft will consume at least 30% of the fuel, which will shorten the flight range of the aircraft and reduce the overall performance of the aircraft. Moreover, the huge friction will l...
