Abstract: A torsional vibration damper has a transmission element on the drive side and a transmission element on the driven side which is rotatable relative to the drive-side transmission element against the action of a damping device. The damping device serves to transmit torque between the two transmission elements and has at least one coupling body that moves along at least one guide path which is formed in one of the transmission elements. This coupling body is displaceable at least in the circumferential direction and is in a working connection with the other transmission element via a driver device so that a deflection of one of the transmission elements in the circumferential direction by a relative movement of the coupling body results in a deflection of the other transmission element. Each guide path is provided with a curvature having a curvature location at the maximum distance from the axis of rotation.

Abstract: A vibration and noise attenuating damper for an automotive drive shaft has a cylindrical body of such size as snugly to fit within the shaft between its reduced diameter ends and be retained in fixed position. The damper has at each end thereof a seal which bears against the surface of the bore of the shaft. The seal has a wall which is accommodated within the tubular body of the damper. The seal may include an impervious closure which closes the end of the damper. The inner surface of the tubular damper body may be formed of a waterproof material.

Abstract: Apparatus for damping vibrations between the output element of the engine and the power train in a motor vehicle has flywheels which are rotatable relative to each other. One flywheel is mounted on the output element of the engine and another flywheel is connectable to the power train by a friction clutch. Vibration dampers are installed between the flywheels, and such dampers are confined in a housing which is provided on the one flywheel and contains a supply of viscous fluid medium for the parts of the dampers. The housing is the input member of the dampers and the output member of the dampers is a flange which extends into the housing and is axially movably coupled to the other flywheel.

Abstract: A protective casing with ring for shafts, in particular cardanic shafts. It comprises, coaxially, a casing, a sleeve ring, and a tubular element. A first end of the sleeve of the ring is destined to engage with a circumferentially groove of the joint, and a second end of the sleeve is adjacent to a constraining end of the casing encompassing the ring. The ring and the casing present, in their respective constraining ends, a multiplicity of hook shaped circumferentially equidistant protrusions, destined to be juxtaposed alternatively forming a circumferential throat for a split elastic locking ring. A rigid annular safety element may cover said constraining ends of the casing and of the ring.

Abstract: A vibration canceler for use on the outer circumference of a shaft rotating about an axis and including two enlargements. The vibration canceler includes half-shells which can be pressed on to the outer circumference of the shaft. The half-shells are joined to at least two inertial masses formed as circle segments by elastic elements which are deformable in a circumferential direction. The inertial masses are joined together by retaining elements. The inertial masses are hingedly joined by link elements and can be restrained in a ring shape by at least one lock element.

Abstract: A centrifugal mass device having at least two centrifugal masses which are rotatable relative to each other against the effect of elastic elements of a torsional damping device. The output-side centrifugal mass, which is more distant from a drive, e.g., the crankshaft of an internal combustion engine, is run radially as well as axially relative to the drive-side centrifugal mass via a support. The support has an axial slide bearing that borders a grease chamber containing a viscous medium, which grease chamber accommodates, at least partially, the torsional damping device. To form a seal for the grease chamber, the axial slide bearing is radially encompassed along at least a portion of its axial extension by at least one axial projection provided on at least one of the centrifugal masses, whereby the axial projection is close to but separated by a gap from an associated region of the other centrifugal mass.

Abstract: A coupling device is provided with two flanges and a resilient annular member disposed between facing surfaces of the flanges. The resilient annular member is provided with a central opening through which a metallic spring is disposed to exert a resistive force against compression of the resilient annular member between the two flanges. The device is particularly well suited for use in a marine propulsion system because of the propulsive force exerted on the shaft system by the propeller. In one particularly preferred arrangement, each of the two flanges is provided with three holes, and the resilient annular member is provided with six holes. The two flanges are offset rotationally to place each of the holes of one flange in alignment with an interstitial space between the holes of the other flange.

Abstract: A seal between two telescoping members in a slip yoke assembly including a driveshaft section and a slip yoke. A circumferential groove is formed in the outer surface of one of the telescoping members of the slip yoke assembly. The groove defines an annular collar which extends circumferentially about the end of the slip yoke. One or more recesses are formed in the bottom of the groove. Additionally, one or more axially extending slots are formed through the collar. Preferably, the slots are angularly offset from the associated recesses by a predetermined amount. One or more radially inwardly extending protrusions are formed at one end of the seal. To install the seal on the slip yoke, the seal is initially oriented relative to the end of the hollow cylindrical end portion such that the protrusions are axially aligned with the slots. Then, the seal is moved toward the slip yoke until the protrusions engage the outer end surface of the slip yoke axially adjacent the slots.

The first shaft has a first yoke attached thereto and the second shaft has a second yoke, smaller than the first yoke, attached thereto. The outer member is pivotally connected to the first yoke about a first rotation axis which is perpendicular to the axis of the first shaft. The inner member is pivotally connected to the second yoke about a second rotation axis which is perpendicular to the axis of the second shaft. The outer member is pivotally connected to the inner member about a third rotation axis which is perpendicular to both the first and second rotation axes. All of the five axes intersect at a joint center point. The constraining unit constrains the third rotation axis to continuously lie generally within the homokinetic plane of the joint.

Abstract: A torsional vibration damper for a flywheel with two inertial masses has two rotating elements which can rotate together and relative to one another. The rotating elements are connected to one another with rotational elasticity by a spring. The spring is located in a channel which is formed on the outside periphery of one of the two rotating elements. The channel is filled at least partly with lubricant. A filling passage for the lubricant is contained in one of the two rotating elements in the vicinity of the hub. The filling passage is closed by the annular surface of a component which, at least in the operationally fully assembled condition, is in contact with one of the two rotating elements and/or the hub. It is thereby possible to eliminate a separate closing cap, along with the corresponding work step which is necessary for the installation of such a closing cap.
