摘要： A bimetallic shaft for use in gearbox applications wherein the member of shaft that protrudes from the gearbox is designed and constructed from a corrosion-resistant metallic compound to prevent corrosion and wear to exposed shaft material. A gearbox comprising a bimetallic shaft having a corrosion-resistant material on the portion of the bimetallic shaft that protrudes from a gearbox housing, wherein a gearbox shaft seal radially surrounds the bimetallic shaft. A method of providing a bimetallic gearbox shaft comprising: a first shaft member comprising a non-corrosion-resistant material and having a first shaft axis, a second shaft member comprising a corrosion-resistant material and having a second shaft axis, and a joint that permanently affixes the first shaft member to the second shaft member such that the first shaft axis is aligned with the second shaft axis.

摘要： A tiltrotor aircraft includes a propulsion system with a fixed engine and a rotatable proprotor. The engine is located below the wing of the tiltrotor aircraft, and the rotatable proprotor assembly is mounted on the top surface of the wing. The engine and proprotor assembly are connected via a series of one or more gearboxes that route the engine output from the engine to the proprotor.

摘要： An apparatus includes a first shaft member including a first material and having a first shaft axis, a first distal end having a first diameter, and a first proximate end, and a second shaft member including a second material different from the first material, and having a second shaft axis, a second proximate end having a second diameter, and a second distal end. A joint permanently affixes the first distal end of the first shaft member to the second proximate end of the second shaft member such that the first shaft axis is aligned with the second shaft axis, where the first distal end substantially abuts the second proximate end, and wherein the first diameter is substantially identical to the second diameter. The second shaft member protrudes through a housing, the housing including a seal sealing against an outer diameter of the second shaft member.
