  • Self-adaptive torsional vibration damper and diesel engine
    Patent number: 10718402
    Abstract: A self-adaptive torsional vibration reducer is provided, which includes an inner casing, an outer casing and resonance bodies provided between the inner casing and the outer casing. Each of the resonance bodies includes a mass-block and constraining springs supporting the mass-block between the inner casing and the outer casing. The resonance bodies are provided in pairs and are symmetrically distributed around a center of the rotating shaft. In a case that a frequency of an excitation force on the rotating shaft is coincided with the resonance frequency, the resonance bodies absorb torsional vibration energy at the frequency to reduce vibration. A diesel engine including the self-adaptive torsional vibration reducer is also provided.
