Abstract

The invention relates to a coupling capable of timely controlling rigidity and damping, which at least comprises a shell, a vibration reduction component capable of transmitting power and adjustably absorbing vibration generated in the transmission process is arranged in the internal space of the shell, and the vibration reduction component at least comprises a first side plate, a second side plate, a middle block and an elastic component, wherein the first side plate and the second side plate are oppositely arranged, and the space between the first side plate and the second side plate is filled with the multiple middle blocks at intervals in the circumferential direction; the elastic assembly is installed in the gap space between the adjacent middle blocks in the mode that the elastic assembly can buffer the relative movement of the adjacent middle blocks in the transmission process. The rigidity of the elastic assembly can be selectively adjusted in the mode that the temperature of a body of the elastic assembly is changed according to vibration generated in the power transmission process of the vibration reduction assembly. The invention further relates to a vibration reduction system capable of timely controlling rigidity and damping.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a shaft coupling with timely controllable stiffness and damping and a vibration damping system thereof. Background technique [0002] Construction machinery such as vehicles and ships need to rely on the transmission system for motion conversion and energy transmission during operation, but the accompanying vibration and noise seriously affect the ride comfort and reduce the service life of the components of the transmission system. With the development of the power plant towards the direction of high power density, the excitation input of the torsional vibration of the transmission system is also increasing, which puts forward higher and higher requirements for the suppression of the torsional vibration of the transmission system. However, the traditional coupling Due to the constraints of its own material properties, its stiffness and damping cannot be changed to meet t...
