Embodiment Construction

[0024] The technical solution of the present invention will be further described with the following examples, which will help the advantages of the technical solution of the present invention, and the effect has a further understanding. Examples do not limit the protection scope of the present invention, and the protection scope of the present invention is determined by the rights Ask to decide.

[0025] figure 1 and figure 2 Shown is a torsional vibration damper 10 coupled to a rotating component 20, such as a crankshaft. The torsional vibration damper 10 comprises a housing 11 extending along a longitudinal axis A and an inner part 12 coaxial with the housing 11 . A plurality of separate cavities 13 are formed between the outer shell 11 and the inner part 12, and the cavities 13 are filled with vibration damping medium, such as pressurized oil. The cavities 13 are distributed sequentially along the circumferential direction and are connected to each other through overflo...

Abstract

A torsional vibration damper comprises an outer housing (11), an inner part (12) that is concentric relative to the outer housing (11), a plurality of chambers (13) formed between the outer housing (11) and the inner part (12), which arc filled with a damping medium and are connected to one another through overflow channels (14), and a plurality of leaf spring configurations (16, 17, 16', 17') that are arranged in the chambers (13) and join the outer housing (11) and the inner part (12) with one another in a torsionally flexible manner. The leaf spring configurations (16, 17, 16', 17') have machining-induced deflections. Two leaf springs with substantially similar deflections are each arranged within a chamber (13). The leaf spring pairs may be arranged in a mirror-image array or in parallel to one another. Thus, the manufacturing cost of a torsional vibration damper can be reduced, while its compact outer dimensions can be maintained.

Description

technical field [0001] The invention relates to a torsional vibration damper. Background technique [0002] The torsional vibration damper includes a shell, an internal part coaxial with the shell, and a plurality of cavities formed between the shell and the internal parts. The cavities are filled with damping media and are connected to each other through overflow channels. In the cavities Several leaf spring assemblies are provided to interconnect the housing and the inner parts in a torsionally elastic manner. [0003] The torque transmission of the housing and internal components is transmitted flexibly through the leaf spring assembly. When the shell and the internal components rotate relative to each other, the transfer of the damping medium between the shell and the internal components achieves a vibration damping effect. [0004] Torsional vibration dampers are mainly used in large two-stroke and four-stroke diesel and gas engines to counteract torsional vibrations ...
