The invention relates to a method for producing a differential housing having at least one machined bearing body and a machined gearing. In order to improve the differential housing in terms of production technology and/or function, the differential housing which has the bearing body is cast from a nodular cast iron material before the differential housing which has the bearing body and the gearing is machined.

A method of manufacturing a motoring system for a gas turbine having the steps of: assembling a pinned mechanical fuse, the pinned mechanical fuse including at least one shear pin; forming an outer housing; installing a reduction gear train into the outer housing, the reduction gear train having an input and an output; operably connecting a motor to the input; operably connecting a clutch to the output using the pinned mechanical fuse, the clutch in operation engages and disengages the reduction gear train; operably connecting a starter to the clutch, the starter having an output shaft; and operably connecting an accessory gearbox to the output shaft of the starter. The clutch is operably connected to the accessory gearbox through the starter and the output shaft. The at least one shear pin in operation shears when torque on the pinned mechanical fuse is greater than or equal to a selected value.

A power transmission device and a method of manufacturing the same capable of shortening a shaft length and improving mountability are provided. A power transmission device according to the present disclosure includes a planetary carrier configured to support a pinion shaft pivotally supporting a pinion gear, rotatably support the pinion gear, and cause the pinion gear to revolve by rotation of the planetary carrier and a planetary carrier plate fixed fo face the planetary carrier on a side where the pinion gear is positioned, and including dog teeth integrally formed with the planetary carrier plate.

A method for producing a cylindrical hollow body (20) made of aluminum, an aluminum alloy, or a light metal alloy, includes casting a hollow body (20) such that the hollow body (20) has an inner and an outer lateral surface (21, 22) and two axial end faces. The method also includes, during the casting process, making at least one defined notch (35, 35′) into one or more of the inner lateral surface (21), the outer lateral surface (22), and the two axial end faces.

A method and apparatus for processing a metallic workpiece with defined edges (e.g., a gear) comprises media blasting of the workpiece by directing a first media against exposed surfaces on the workpiece to increase the root strength of the gear, the blasting causing the defined edges to be radiused or mushroomed, ceasing the media blasting, loading the workpiece into a finishing apparatus, and subjecting the workpiece to a finishing process with a second media, the exposed surfaces on the workpiece being subjected to the finishing process to reduce the radiused edges on the workpiece created from the media blasting. The process of moving the workpiece to the spindle-finishing apparatus from the media blasting may be performed automatically by a machine. Once the workpiece has been subjected to the finishing process with the second media, it may be removed from the spindle-finishing machine, washed, and rinsed with rust inhibitor whereby wear properties of the workpiece are enhanced.

A method of manufacturing pumps of different performances for use in a blood treatment device, preferably a dialysis machine, having a pump housing or a pump housing portion for supportingly holding two gear wheels in meshing engagement. The method includes the step of primary shaping of a universal pump housing blank with all features common to the different pumps as well as with such oversizes as to allow machining for manufacturing all different pumps from the same primary-shaped pump housing blank. The method also includes the step of individualizing the universal pump housing blank by machining in the region of the oversizes to achieve the respective performance.
