An inner wheel element (15a) is embedded in an outer wheel element (16a), such that a continuous range from an inner diameter side circumferential surface configuring an inner surface of a first annular concave part (22), through an outer circumferential surface of the inner wheel element (15a), to an inner diameter side circumferential surface configuring an inner surface of a second annular concave part (38) in a surface of the inner wheel element (15a) is covered over the entire circumference. Accordingly, a structure is achieved which easily secures a holding power of the synthetic resin outer wheel element with respect to the inner wheel element.

A rotating component includes a metal plate fixed to an end portion of the metal shaft, and a resin valve gear integrally formed with the plate by insert molding. The plate is formed with a circular fitting hole that fits with the end portion of the shaft, and a positioning recess that is recessed from one side to the other side of the plate.

The disclosure relates to an assembly comprising a component rotatable about a rotary axis for an actuating drive comprising a sensor element attached to the rotatable component. The rotatable component has a support surface from which a fixing element protrudes in parallel to the rotary axis. The sensor element includes an opening. The sensor element is arranged on the support surface in such a manner that the fixing element penetrates the opening. A surface of the sensor element adjacent to the opening has a structure. A top portion of the fixing element is in interlocking engagement with the structure so that the attached sensor element is connected to the component in a torque-resistant manner.

A gearwheel pair for a gear unit, comprising a first gear and a second gear, which can be meshed with one another, wherein the first gear consists entirely or partially of metal or plastic and the second spur gear comprises an outer part having a gear rim made of a first plastic and having a number of injection-molded portions, an inlay part made of metal, and a connecting part, which is arranged between the inlay part and the outer part and is made of a second plastic for the interlocked and/or materially-bonded connection of the inlay part and the outer part and further relates to the second spur gear per se, a gear unit having such a gearwheel pair, and a method for producing a second gear, which is used for such a gear unit.

A method is disclosed for additively manufacturing a composite structure. The method may include discharging a composite material from a print head and moving the print head during discharging to fabricate a preform from the composite material. The method may also include densifying the preform with a densifying material, and heating the preform to pyrolize the at least one of the composite material and the densifying material.

A wide section 71d which contacts a connector member and positions the connector member relative to a connector housing part is provided in a section where a first securing part 71b of a cover member 70 is provided and is configured so as to be wider than the other parts of the section where the first securing part 71b of the cover member 70 is provided; hence, it is possible to use the wide section 71d in the pressing section (pressing point OP) of an extrusion pin. As a result, it is possible to suppress distortion of the cover member 70 and to sufficiently smooth the welded section (first securing part 71b) of the cover member 70 even when the shape of the cover member 70 is complicated.

A composite gear includes: a first member comprising a rotation shaft portion and a disk-shaped web extending in radial directions from the rotation shaft portion; and a second member comprising at least one engaging tooth on an outer periphery thereof and provided being supported by the web so as to surround an outer periphery of the first member. A space is provided between the second member and an outermost peripheral surface of the first member in a radial direction, a space is provided between the first member and an innermost peripheral surface of the second member in a radial direction, and at least one of the first member and the second member is formed to nip another of the first member and the second member from both sides thereof in an axial direction of the rotation shaft portion.

An additive manufacturing method includes providing a first composite material and forming a composite part matrix using the first composite material and defining a first layer, applying a first fiber reinforcing material to the composite part matrix atop and in contact with the first layer of the composite part matrix such that fibers of the first fiber reinforcing material are oriented in a first direction and form a second layer on the composite part matrix, applying a second fiber reinforcing material to the composite part matrix atop and in contact with the first fiber reinforcing material such that fibers of the second fiber reinforcing material are oriented in a second direction orthogonal to the first direction and form a third layer on the composite part matrix, applying the first composite material to the composite part matrix, and curing the composite part matrix to create a composite product.

Provided is a bevel gear component including a plurality of teeth protruding in an axial direction, extending toward an outer peripheral side, and arranged at equal pitches in a circumferential direction, the bevel gear component including a fiber material having a shape corresponding to an arrangement pattern of the plurality of teeth and wound around a center axis.
