Title:
SELF-ADAPTIVE TORSIONAL VIBRATION DAMPER AND DIESEL ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/080751
Kind Code:
A1
Abstract:
A self-adaptive torsional vibration damper, which comprises: an inner casing (1), an outer casing (2) and resonance bodies that are disposed between the inner casing (1) and the outer casing (2); the resonance bodies comprise mass blocks (4) and restraining springs (3) that support the mass blocks (4) between the inner casing (1) and the outer casing (2); the resonant bodies are arranged in pairs and are symmetrically distributed about the center of a rotating shaft. When the excitation force frequency of the rotating shaft coincides with a resonant frequency, the resonant bodies targetedly absorb the torsional vibration energy at said frequency so as to reduce vibration, thereby reducing a torsional amplitude value from a source angle, and ensuring the safe operation of a shaft system. The present invention further relates to a diesel engine comprising a self-adaptive torsional vibration damper.
