A squeeze film damper is provided, which includes a bearing cartridge (6), a housing (4), in which the bearing cartridge (6) is accommodated, and a squeeze film in a gap (22) between the housing (4) and the bearing cartridge (6) for producing a damping force directed opposite a circulating radial exciter force, which is generated by an imbalance retained in the bearing cartridge (6). In the squeeze film damper, an arrangement (28) for attenuating the damping force according to the circumferential position are provided around the bearing cartridge (6).

The invention relates to a method for manufacturing a hinge between two workpieces or components; first a hinge socket is inserted in an opening of the first component and then a hinge pin is inserted in the hinge socket; the second component can be fastened to the hinge pin end protruding from the hinge socket.
摘要:
A method for setting blind rivet elements in which the setting of the respective blind rivet element introduced into a pre-hole of the work piece and/or the formation of a rivet collar takes place in a setting stroke (SH) through the permanent deformation of a section of the blind rivet element by subjecting an end of the blind rivet element to a traction force by a traction element of a setting tool while simultaneously supporting another end of the blind rivet element on a support part of the setting tool counter to the traction force.
摘要:
An apparatus and a method for the binaural reproduction of audio sonar signals, which can be direction-selectively received by a sonar system having a receiving antenna provided with a plurality of transducers, and at least one direction generator, and which can be modified by binaural audio signal processing. The apparatus comprises a portable sound reproduction device, particularly a headphone, and a head tracking sensor connected to the sound reproduction device for registering position changes of the sound reproduction device. Signals, associated with the position changes, are generated, which are transferred to the direction generator, in order to select a direction of the sound waves to be received.
摘要:
The invention relates to a joint bush, for use in a joint between two components or workpieces, comprising a first sleeve-like bush section, which transforms at one sleeve end into a second flange-like bush section which projects over the circumferential surface of the first bush section.
摘要:
The invention relates to a new design for a hydraulic processing tong for processing workpieces, with a tool, which in a first tool part has an axially movable press ram or plunger, which with a first end or a tool located there and an opposing workpiece assembly forms a work area or work gap and with the first end can move toward and away from the workpiece assembly, and with a hydraulic actuating device for applying a force to the press ram, causing it to move in the direction of the workpiece assembly.

The invention relates to a processing clamp for machining and/or processing of workpieces with large processing forces, including a clamp body with a first clamp arm and a second clamp arm and at least a tool with a first tool part and a second tool part which are movable relative to each other and define a working region. The first tool part is arranged to be traversable along a vertical tool axis on the first clamp arm to close the working region and the second tool part is arranged on the second clamp arm to form a workpiece abutment for at least one workpiece. The first tool part is adjustable from a starting position into a working position by an adjustment device. An actuating device is provided for applying a high processing power acting along the tool axis to the first tool part after the adjustment into the working position by the adjustment device.

Process for attaching a functional element to a plastically deformable flat material or workpiece, the functional element on a contact surface having a rivet collar which is formed by a hollow or tubular section and which stands away over this surface, in the joining area in the flat material by plastic deformation a dome-like section being formed which with its base projects over the plane of the flat material surrounding this section and on the base has a joining opening, and the attachment of the functional element to the flat material in a joining and riveting process taking place by insertion of the rivet collar into the joining opening and by plastic deformation of the rivet collar such that the base is held in a region of the base which surrounds the joining opening between the deformed rivet collar and the contact surface or end side of the functional element, the functional element being anchored on the edge region which surrounds the joining opening without reducing the diameter of the joining opening.
