Abstract:
A method and device for measuring dimensions of a feature on or near an object using a video inspection device. A reference surface is determined based on reference surface points on the surface of the object. One or more measurement cursors are placed on measurement pixels of an image of the object. Projected reference surface points associated with the measurement pixels on the reference surface are determined. The dimensions of the feature can be determined using the three-dimensional coordinates of at least one of the projected reference surface points.
Abstract:
In a telemetry system (100) in a high-temperature environment of a combustion turbine engine (10), a wireless power-receiving coil assembly (116) may be affixed to a movable component (104) of the turbine engine. Power-receiving coil assembly (116) may include a radio-frequency transparent housing (130) having an opening (132). A lid (134) may be provided to close the opening of the housing. Lid (134) may be positioned to provide support against a surface (120) of the movable component. An induction coil (133) is disposed in the housing distally away from the lid and encased between a first layer (136) and a last layer (140) of a potting adhesive. Lid (134) is arranged to provide vibrational buffering between the surface (120) of the movable component (104) and the layers encasing the induction coil.
Abstract:
The invention relates to an adjusting shaft arrangement (1) for an exhaust-gas turbocharger (15) that is equipped in particular with a variable turbine geometry (VTG) and/or a wastegate arrangement, having an adjusting shaft (2) that has a fixing section (3); having an outer lever (4) that is connected to the adjusting shaft (2) via the fixing section (3); and having a bearing sleeve (5) that is arranged on a main body (6) of the adjusting shaft (2); wherein the adjusting shaft (2) has a smooth cylindrical outer contour over its entire length (LA); the bearing sleeve (5) has a stepped outer contour (10) with a first abutment surface (11), and a bushing (12) is arranged on the bearing sleeve (5), the inner contour (13) of which bushing is matched to the outer contour (10) of the bearing sleeve (5) and which bushing has a second abutment surface (14) of complementary form which abuts against the abutment surface (11).
Abstract:
An actuation system for a bleed valve includes first and second bell cranks connected by a connecting link. The first bell crank has a first arm that is coupled to a bleed valve and a second arm that is coupled to the connecting link. The connecting link has a first end coupled to the second arm of the first bell crank and a second end coupled to a first arm of the second bell crank. A second arm of the second bell crank is coupled to an actuating element. Input is communicated through the actuating element to move the bleed valve between open and closed positions via the first and second bell cranks.
Abstract:
Die vorliegende Erfindung betrifft eine Ladeeinrichtung (1), insbesondere einen Abgasturbolader einer Brennkraftmaschine, mit einer variablen Turbinen- oder Verdichtergeometrie (2) und einer Stelleinrichtung (3), welche die variable Turbinen- oder Verdichtergeometrie (2) verstellt. Weiter weist die Stelleinrichtung (2) eine Mindestsollbegrenzung und/oder eine Höchstsollbegrenzung auf, die eine Mindestsolldurchströmung und/oder eine Höchstsolldurchströmung der variablen Turbinen- oder Verdichtergeometrie (2) bestimmt. Erfindungswesentlich ist dabei, dass die Mindestsollbegrenzung und/oder Höchstsollbegrenzung der Stelleinrichtung (3) einstellbar und insbesondere nachjustierbar sind/ist. Dadurch ist/sind insbesondere Abweichungen, beispielsweise durch Verschleiß verursacht, der Mindestsollbegrenzung und/oder Höchstsollbegrenzung der Stelleinrichtung (3) von der zugeordneten Mindestsolldurchströmung und/oder Höchstsolldurchströmung der variablen Turbinen- oder Verdichtergeometrie (2) durch Anpassen der Mindestsollbegrenzung und/oder Höchstsollbegrenzung ausgleichbar. Die vorliegende Erfindung betrifft weiter ein Verfahren zum Betreiben einer derartigen Ladeeinrichtung (1).
Abstract:
The invention relates to an exhaust-gas turbocharger (1) having a compressor (2) which has a compressor housing (3), having a turbine (4) which has a turbine housing (5), having a bearing housing (6) between the compressor housing (3) and the turbine housing (5), and having a control capsule (7) which has a housing (8) on which is provided a retaining device (9) which interacts with a fastening device (10) on the turbocharger in order to fix the control capsule (6) to the compressor housing (3), the turbine housing (5) or the bearing housing (6), wherein the retaining device (9) is arranged on an outer circumferential region (11) of the control capsule (7), and wherein the fastening device (10) fixes the retaining device (9) in a non-positively locking manner.
