Problems solved by technology

However, due to the axial vibration of the shaft, the cover is loaded with lateral vibrations by the inertia ring, which ultimately has an effect on the weld
As a result, elastic or plastic deformation of the cover can lead to loads, in particular bending stresses, on the weld seam and, depending on the design of the machine shaft and the machine involved, can even lead to failure of the weld seam at high forces

Embodiment Construction

[0035] in particular, figure 1 The viscous torsional vibration damper 1 has a damper housing 2 having an intermediate opening 14 for attach to the machine shaft.

[0036] figure 2 A rotary axis 100 is shown, the rotary axis extends through the intermediate opening 14 and the viscous torsional vibration damper 1 is rotatably disposed about the axis of rotation.

[0037] The damper housing 2 of the viscous torsion damper 1 has a first wall and a second wall having a radially outer peripheral surface 11 extending parallel to the first wall. Between the outer peripheral surface 11 and the inner circumference surface 12 and therefore also provided a working chamber 5 for providing the inertial ring 4 between the first wall and the second wall. The inertial ring 4 can be supported in the working chamber 5 by the support element and can be placed in the working chamber 5 through the chamber opening 26.

[0038] A shear gap 10 is provided between the inner circumference surface 12 and th...

Abstract

The invention relates to a viscous torsional-vibration damper (1) comprising a damper housing (2) having an axis of rotation (100), an annular working chamber (5) filled with a damping medium, an inertia ring (4) arranged inside the working chamber (5), and a cover (15) for media-tight closure of the working chamber (5), wherein the cover (15) is connected to the damper housing (2) peripherally on one side by a sequence of a butt seam (16) and an overlap seam (17). The invention also relates to a method for producing a viscous torsional-vibration damper.

Description

Technical field [0001] The present invention relates to a viscous torsional vibration damper according to the preamble of claim 1, and a method for manufacturing the viscous torsional vibration damper according to the preamble of claim 11. Background technique [0002] This type of torsional vibration damper is used to vibrate the torsional vibration at the machine axis (often the engine crankshaft). At the machine axis, the damper housing of the torsional vibration damper is rigidly connected to the machine shaft (often the engine crankshaft), and the torsional vibration of the machine axis should be damped. The damper housing and the inertia ring have no slippery average rotational speed. It is first transmitted to the damper housing (the torsional vibration is superimposed). If the viscous fluid, such as silicone oil (the fluid fills the narrow shear gap), the inertial ring will also rotate. This coupling is elastic and vibration-vibration. Therefore, the relative rotation ang...
