Abstract:
A torsional vibration damper, comprising: a drive-side transmission element; an output-side transmission element rotatable relative to the drive-side transmission element; a radial slide bearing arranged so as to center the output-side transmission element relative to the drive-side transmission element; an axial slide bearing arranged so as to hold the output-side transmission element at a predeterminable axial distance from the drive-side transmission element, the drive-side transmission element having a component arranged to act on an outer circumference of the radial slide bearing, the output-side transmission element having a component arranged to act on an inner circumference of the radial slide bearing, the axial slide bearing being arranged to rest on the component of the drive-side transmission element that acts on the outer circumference of the radial slide bearing and on the component of the output side transmission element that acts on the inner circumference of the radial slide bearing so as to form, together with the component of the output-side transmission element and the component of the drive-side transmission element, a covering for the radial slide bearing which protects the radial slide bearing against an afflux of solid particles, apertures being provided in the component of the output-side transmission element; attachment means, that pass through the apertures, for connecting the drive-side transmission element to a crank shaft of a drive, the axial slide bearing having passageway openings for the attachment means, which passageway openings are arranged to rest at least partially inside a cross-sectional area of the apertures of the component of the output-side transmission element; and means, associated with each of the passageway openings of the axial slide bearing, for protecting against loss of the attachment means, the loss protector means being formed by the inner diameter of each passageway opening of the axial slide bearing being adjusted to a maximum diameter of the attachment means so that the attachment means, at the point of maximum diameter, can be pressed through the given passageway opening only under application of an axial force of a predeterminable level.
