    摘要: A damper (10) of vibrations of the viscous fluid type has a two-piece housing (16) of which a plate (21) is formed by a spinforming process (141). The formed plate (21) has a plurality of internal walls (32) of which at least a portion of the walls (32) are usable as bearing surfaces after being spinformed and require no further machining thereof. The damper (10) includes a plurality of individual bearings (26) for radially and axially positioning a rotatable weight (20) within the housing (16) to form preselected spaces (26) between the housing (16) and the weight (20). An annular supply chamber (27) and the preselected spaces (26) have a viscous fluid (28) disposed therein to provide a damping medium between the rotatable weight (20) and the housing (16).

    摘要: Vorrichtung zur Änderung der zeitlichen Durchflußmenge eines flüssigen Dämpfungsmittels bei einem Drehscwingungsdämpfer, insbesondere für Kolbenmotoren, in dessen mit der An- bzw. Abtriebswelle verbundenem, umlaufenden zylindrischen Dämp­fergehäuse (1) Stirnzahnräder (2, 3) planetenartig gelagert sind und, mit einem auf der Ab- bzw. Antriebswelle sitzenden, zentralen Stirnzahnrad (2) in Eingriff stehend, eine Zahnradpum­pe für einen geschlossenen Kreislauf des Dämpfungsmittels bilden, mit einer Speicherkammer (13) in der Förderleitung für das Dämpfungsmittel auf der jeweiligen Druckseite, wobei die Speicherkammer ein elastisch veränderbares Volumen aufweist, und in der Druckseite der Förderleitung (4) ein drehzahlabhängig gesteuertes Kolbenventil (7) vorgesehen ist, dessen Kolben (8) geeignet ist, als Drosselstellglied durch seine Axialbewe­gung den Querschnitt der Förderleitung zu verändern.

    摘要: An inertia damper has a mounting base (10) to be mounted on a rotary shaft (40) and an inertia weight component (20) which is coupled to the mounting base through a vibration absorbing layer so the vibration absorbing layer being made of a gel material with a penetration value of approximately 50 to 200.
    The inertia weight component is adhered to one surface of the vibration absorbing layer and the other surface of the vibration absorbing layer is adhered to the mounting base of the rotary shaft.
    A vibration wave generated at the rotary shaft side is dispersedly absorbed by deformation of gel material which forms the vibration absorbing layer and a vibratory component can be removed from a braking motion.

    摘要: A torsional vibration damper (2) according to the invention has a drive-input-side transmission element (88) which is connected to a drive input (1), a drive-output-side transmission element (92) which can be operatively connected to a drive output (86) and can be rotationally deflected relative to the drive-input-side transmission element (88), and a damping device (31) which is provided between the two transmission elements and has a spring system (14) which serves to transmit a torque between the drive-input-side and the drive-output-side transmission elements and has at least one accumulator space (32) which contains a gaseous medium. In this torsional vibration damper (2), the respective accumulator space of the spring system is operatively connected to an in each case associated liquid-medium-containing pressure space (27) of a pressure circuit (120), wherein it is at least substantially possible by means of the pressure circuit, at least in the event of a change in the torque which is to be transmitted, for an adaptation of the characteristic curve of the spring system to the changed torque to be initiated by means of a resetting of the pressure acting in the respective pressure space.
