A method of replacing at least one tooth of a gear includes providing a tool jig including a mounting block with a plurality of indexing jig features. The tool jig also includes a tool-supporting feature in laterally movable contact with a jig rail feature. With at least one indexing jig feature, relative motion of the tool jig relative to the gear is resisted. A material-removal tool is operated, while attached to the tool-supporting feature in the tooth-removal position, to remove at least a portion of a working circumference of the gear including a native gear tooth to be replaced. Motion of the material-removal tool is guided to generate a circumferential gear cut including a relatively smooth first cut surface formed by removal of at least the native gear tooth to be replaced. The material-removal tool is removed from the tool-supporting feature. The tool jig is removed from the gear.

An apparatus for replacing at least one tooth of a gear includes an elongate anchoring lip having a laterally extending lip body with at least one anchoring hole extending longitudinally therethrough. The lip body is bounded within a lateral plane by transversely spaced front and rear lip faces and laterally spaced first and second side edges. A tooth block extends longitudinally from a selected one of the front and rear lip faces. The tooth block includes at least one replacement gear tooth extending longitudinally therealong. The tooth block is spaced laterally apart from at least one of the first and second side edges, with at least a portion of the lip body extending laterally between the tooth block and the at least one of the first and second side edges.

A carrier and at least one pin shaft of a gearbox of a wind turbine and method of manufacturing same includes forming the carrier and the pin shaft(s) as a single part or separate components. Further, the method includes forming one or more voids in the pin shaft(s) and/or the carrier via additive manufacturing. As such, the void(s) is configured to increase flexibility of the pin shaft(s)/carrier so as to improve a load distribution thereof.

A device for producing a functional shaft and a functional shaft are provided in which a functional element which is provided with a pocket is inserted into a retaining element, a shaft is inserted into the pocket, and a force applied to the functional element while the shaft is being inserted into the pocket is measured.

Method for producing a compound, rotationally symmetrical component (3) with internal and external teeth consisting of a blank (1) and a toothed body (5), wherein the two parts (1, 5) are designed in the form of a pot and in a first method step are inserted coaxially one inside another with interlocking, mutual support and in a second method step are interlocked together with at least one forming tool (17, 27) applied against the (inner and/or outer) circumference, wherein in the second method step the circumferential surface (14, 14) of said blank (1) is continuously deformed in a rolling forming process in the axial direction and in the radial direction such that the circumferential surface (14, 14) of the blank (1) is deformed to interlock into the tooth bases (10) of the teeth (6) of the toothed body (5).

A method of reducing the required machining on a pin type carrier, such as a planetary gear carrier, may utilize a combined drilling and milling operation to reduce the required machining. A hole in a surface may be formed during the drilling operation and the surface may be machined to a desired level during the milling operation. A tool having a leading drill feature and a trailing mill feature may be used to sequentially form the hole and mill the surface in a single operation.
