Abstract: A method of manufacturing is provided. The method can include determining a cross-sectional shape of an object to be inspected using a sensor configured with a sensor coil. The method can also include providing a substrate having a profile matching the cross-sectional shape of the object. The method can further include applying a dielectric material to the substrate in a patter matching a shape of the sensor coil. The method can also include forming a first layer of a first material on the dielectric material by sputtering particles of the first material on the dielectric material in the pattern and forming additional layers of the first material atop the first layer by iteratively depositing the additional layers in the pattern via an additive manufacturing technique. A sensor including a sensor coil formed via the method is also provided.

Abstract: A planetary gearbox having a sun gear, a plurality of planet gears, a ring gear, and a plurality of journal bearing pins. At its axially forward face side and/or at its axially rearward face side, each planet gear forms a recess that extends inside the planet gear starting from the face side. The planet gear forms a protrusion at its axially forward face side and/or at its axially rearward face side. The protrusion has an axial extent and a radial extent, wherein the radial extent is limited at the respective face side to the area between the planet gear inner bore and the radial inner limit of the respective recess in the planet gear, and wherein the protrusion is configured to provide for a flow path for oil emerging from the journal bearing that guides the oil away from the journal bearing.
