The torque support (12a, 12b, 13a, 13b) of each gear unit (1a, 1b) surrounds the transmission housing (9) of the respective other gear unit (1b, 1a) in a pincer-like manner and contacts the housing (9) symmetrically with respect to a straight line connecting the output shafts (10) at two support points which relative to a vertical plane extending through the output shaft (10) of the respective other gear unit (1a, 1b) are located towards the gear unit (1a, 1b) which has the torque support (12a, 12b, 13a, 13b).


Methods for CAD modeling and corresponding systems (100) and computer-readable mediums (126). A method includes receiving (1205) a CAD model (400) including a selection of multiple adjacent web faces (402, 404) of the CAD model and at least one datum plane (420) of the CAD model that intersects the web faces, receiving (1210) a selection of a joggle side (434) of the CAD model with respect to the datum plane, and receiving (1215) an offset direction (442, 444) and an offset depth value corresponding to each selected web face. The method includes creating (1220) at least one joggle feature (471) in the CAD model by moving a portion of each of the selected web faces on the joggle side of the CAD model according to the respective offset directions and the depth values, including creating at least one runout (452, 454) for each selected web face at the datum plane, to produce a modified CAD model (470). The method includes storing (1225) the modified CAD model. The multiple adjacent web faces can include intermediate web faces (704).

Powder bed-based, additive production method, for example laser melting, and installation for carrying out said method. It is provided that layers (20) as a whole are applied onto the powder bed (16), in which the component (19) is to be produced, by means of a support component (21). The layer (20) can be removed from a supply powder bed (22) that has the same dimensions as the powder bed (16). In addition, the layer (20) can be compressed by means of a compressor (25). The advantage of the application of layers (20), according to the invention, is that these layers are of a higher quality. They are more compressed and flat as a result of their contact to the carrier component (21). The quality of the component that is to be produced (19) can thus also be improved.


A turbine abradable component includes a support surface and a thermally sprayed ceramic/metallic abradable substrate coupled to the support surface for orientation proximal a rotating turbine blade tip circumferential swept path. An elongated pixelated major planform pattern (PMPP) of a plurality of discontinuous micro surface features (MSF) project from the substrate surface. The PMPP repeats radially along the swept path in the blade tip rotational direction, for selectively directing airflow between the blade tip and the substrate surface. Each MSF is defined by a pair of first opposed lateral walls defining a width, length and height that occupy a volume envelope of 1-12 cubic millimeters. The PMPP arrays of MSFs provide airflow control of hot gasses in the gap between the abradable surface and the blade tip with smaller potential rubbing surface area than solid projecting ribs with similar planform profiles.
