Problems solved by technology
However, the dynamic characteristic parameters of the elastic coupling are related to the hardness, elasticity and damping properties of the elastic element itself. The parameters are mutually restricted and the relationship is complicated. It is difficult to obtain the dynamic characteristic parameters, and the vibration reduction effect is restricted by many factors. Cannot accurately dampen vibrations for frequency-specific external stimuli
At the same time, compared with the rigid coupling, due to the dynamic load, the elastic coupling has a deviation in the input and output shaft angles, which cannot meet the requirements of high-precision transmission

The invention provides a shaft coupling vibration reduction system and method. The shaft coupling vibration reduction system comprises an output flange, an input flange, a vibration reduction unit, a detection unit, a motor control unit and a processing unit. The vibration reduction unit is arranged between the input flange and the output flange and used for reducing the torsional vibration of an input shaft and an output shaft. The detection unit is connected with the input shaft and used for detecting the torsional angle displacement of the input shaft, determining the external excitation frequency according to the torsional angle displacement, and transmitting the external excitation frequency to the processing unit. The processing unit is used for receiving the external excitation frequency, determining a control signal of a motor according to the external excitation frequency and the rotation speed of a transmission shaft, and transmitting the control signal of the motor to the motor control unit. The motor control unit is connected with the vibration reduction unit and used for receiving the control signal of the motor and controlling the motor to drive the vibration reduction unit to work. By the adoption of the shaft coupling vibration reduction system and method, self-adaptive vibration reduction of a vibration reduction shaft coupler under different working conditions is achieved, and stable operation of the motor and the transmission shaft is guaranteed.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of shaft couplings, in particular to a shaft coupling vibration reduction system and method. Background technique [0002] Coupling is an indispensable connecting part in the transmission mechanism. It is used in almost every field. Its main function is to connect two shafts (driving shaft and driven shaft) in different mechanisms so that they can rotate together transmit torque. Traditional couplings are all contact type. According to whether the coupling contains elastic elements, they can be divided into rigid couplings and elastic couplings. There are no elastic elements in rigid couplings, which are often used for stable working conditions and transmission accuracy requirements. In high-level institutions; elastic couplings are equipped with elastic materials such as rubber or plastic, which can absorb and slow down the lateral and bending vibrations of the transmission shaft, so ...
