The invention discloses an active thrust balance type shafting longitudinal vibration reduction device. The active thrust balance type shafting longitudinal vibration reduction device comprises a shell, a thrust block mounted in the shell, a longitudinal vibration reduction structure opposite to the thrust block, a hydraulic pipeline configured with the vibration reduction structure, a hydraulic machine and a thrust detection control module, wherein the shell is mounted on a thrust shaft in a sleeving manner, and the shell and the thrust shaft are configured in a sealed manner. The thrust block and the thrust shaft are connected in an abutting manner. The longitudinal vibration reduction structure comprises a piston cylinder, a piston rod, a vibration reduction element and a piston cylinder end cover. One end of the piston rod stretches out of the piston cylinder and is connected with the thrust block in an abutting manner, and the other end of the piston rod is arranged in the pistoncylinder. One end of the vibration reduction element is connected with the piston rod in an abutting manner, and the other end of the vibration reduction element is connected with the piston cylinderend cover in an abutting manner. By means of the device, counter equivalent static thrust is provided in a cabin, static thrust brought by a propeller and deepwater pressure to shafting is compensated, the vibration reduction element only transmits and attenuates pulsation exciting force of the proper, and longitudinal vibration control over a propeller shaft system is expanded to large amplitudeand low frequency.

    本发明公开了一种主动推力平衡式轴系纵向减振装置,包括套装在推力轴上并与推力轴密封配置的壳体、安设在壳体内的推力块、与推力块相对设置的纵向减振结构、与减振结构相配置的液压管路、液压机、推力检测控制模块,所述推力块与推力轴相抵接,所述纵向减振结构包括活塞缸、活塞杆、减振元件、活塞缸端盖,所述活塞杆的一端伸出活塞缸外与推力块相抵接,另一端置入活塞缸内,所述减振元件的一端与活塞杆相抵接,另一端与活塞缸端盖相抵接。通过本装置在舱内提供反向的等效的静推力,补偿螺旋桨和深水压力给轴系带来的静推力,使得减振元件仅传递并衰减螺旋桨脉动激励力,对桨轴系统的纵向振动控制向大幅低频扩展。
