Problems solved by technology
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 lead to rapid wear of the thrust bearing, which will bring hidden dangers to flight safety.

The invention discloses an extrusion and traction double effect special magnetic suspension bearing for an aircraft engine. The bearing mainly and structurally comprises a shell, a big magnetic ring, a big supporting ring, a small magnetic ring, a small supporting ring and a main shaft, wherein the big magnetic ring and the big supporting ring are arranged in the shell and the small magnetic ring and the small supporting ring are arranged on the main shaft.
Description
Technical field [0001] The invention relates to a special magnetic suspension bearing for an aircraft engine with extrusion and traction double effects, in particular to a multilayer extrusion traction double effect magnetic suspension bearing. It belongs to the technical field of new aircraft engines. Background technique [0002] In today's aircraft engines, when the main shaft rotates, it will generate several tons to more than ten tons of axial pressure. This rotational pressure is transmitted to the thrust bearing, which will generate huge noise and cause huge friction and heat. 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 lead to rapid wear of the thrust bearing, which will bring ...
