20150071722 | METHOD AND AUTOMATIC MACHINE FOR MACHINING A GEAR WHEEL - The axis of rotation of a gear wheel subjected to thermal treatment and comprising at least one intermediate crown wheel and a pair of lateral tubular hubs arranged on opposite sides of the crown wheel is restored automatically by coupling a first of the hubs to a head rotating about a fixed axis of own rotation axis, displacing the other hub in a direction transverse to the fixed axis until both of the hubs and the crown wheel are brought into positions substantially sharing the fixed axis and providing on each of the hubs a respective centring surface sharing the fixed axis without uncoupling the first hub from the rotating head and keeping the gear wheel in a vertical and angularly fixed position. | 03-12-2015 |
20140341713 | LOW PRESSURE TURBINE PROVIDED WITH SPLITTERS AT THE LAST STATOR ARRAY, IN PARTICULAR FOR A GAS TURBINE ENGINE - A low pressure turbine, in particular for a gas turbine engine, extends along an axis, has an annular conduit for guiding a gas flow and is provided with a plurality of stator arrays of blades and a plurality of rotor arrays of blades; the last of the stator arrays, considering the advancement direction of the gas flow, has a plurality of blades, which define a plurality of spaces between them in circumferential direction; the spaces are split by respective splitters into a radially outer conduit and into a radially inner conduit; the radial position of the splitters is in the neighborhood of a radial reference position such that at least one acoustic mode is of the cut-on type in the radially inner conduit. | 11-20-2014 |
20140298651 | Method For Making A Shaped Turbine Aerofoil - According to the method, a turbine aerofoil is made starting from a reference aerofoil, locally reducing the metallic exit angle at the trailing edge in two areas which substantially correspond, in use, to the position of the peaks of the secondary flows in the boundary layer. | 10-09-2014 |
20140182252 | FILTERING NET, IN PARTICULAR FOR A ROTARY SEPARATOR - A filtering net, in particular for a rotary separator, has a plurality of cells, which are substantially equal to one another and are defined by the replication of a base cell along two transversal directions of replication; the base cell comprises at least one intermediate filament and a first and a second end filament, arranged on opposite sides of the intermediate filament; the intermediate filament and the end filaments extend along respective longitudinal axes which are parallel; cross-sectioning the base cell with any plane orthogonal to the longitudinal axes of the filaments and joining, on said plane, the trace of each longitudinal axis with the trace of the adjacent longitudinal axis by a respective straight line, the two straight lines are incident at the trace of the longitudinal axis of the intermediate filament and form an incidence angle of between approximately 90° and 160°. | 07-03-2014 |
20140127400 | Method For Repairing An Aluminium Alloy Component - The invention refers to a method for the repair of an aluminium alloy component, in particular a precipitation-hardened aluminium alloy component, comprising the steps of: | 05-08-2014 |
