摘要:
An apparatus for damping the torsional excitation of a hollow drive shaft, the apparatus comprising: an elongate member that extends along the interior of the drive shaft, one end of the member being secured to one end of the drive shaft, the other end of the member being disposed at the other end of the drive shaft; and a hydraulic damping device (11) secured to the other end of the drive shaft for damping vibration of the other end of the member, the hydraulic damping device including: a piston and cylinder arrangement (25) having first and second hydraulic chambers (45a, 47a or 65a, 65b); a reservoir (19) of hydraulic fluid; and hydraulic circuitry by means of which the hydraulic chambers communicate with the reservoir (19) of hydraulic fluid, wherein the hydraulic damping device is arranged so that any leakage of hydraulic fluid from the first and second hydraulic chambers via a piston/cylinder interface passes to the reservoir of hydraulic fluid.
摘要(中):
一种用于缓冲中空驱动轴的扭转激励的装置,该装置包括:细长构件,其沿着驱动轴的内部延伸,该构件的一端固定在驱动轴的一端,另一端 构件设置在所述驱动轴的另一端; 以及液压阻尼装置(11),其固定到所述驱动轴的另一端以阻尼所述构件的另一端的振动,所述液压阻尼装置包括:具有第一和第二液压室(45a)的活塞和气缸装置 ,47a或65a,65b); 液压油箱(19); 和液压回路,液压室通过该液压回路与液压流体的储存器(19)连通,其中液压阻尼装置被布置成使得液压流体经由活塞/汽缸接口从第一和第二液压室的任何泄漏传递到 液压油库。
