    • The present disclosure discloses a pre-tightening locking device (100) for retaining a component on a shaft, comprising: a backing ring (1) having a first end face (11) and an opposite second end face (12), wherein the backing ring is mounted on the shaft with the first end face (11) thereof closely engaging with the component to be retained; a pre-tightening nut (3) threadedly coupled on the shaft, wherein one end of the pre-tightening nut engages with the second end face (12) of the backing ring (1); a hydraulic nut (4) arranged outside of the pre-tightening nut (3) through threads, wherein an annular piston (5) of the hydraulic nut (4) is capable of exerting an acting force on the backing ring (1) under fluid pressure so as to form an interval between the backing ring (1) and the pre-tightening nut (3); and a filling member for filling the interval. A filling member is provided for filling the interval so that a pre-tightening force can be maintained, which ensures that the component on the shaft is closely retained. Under this condition, the hydraulic nut can be removed, whereby the cost is significantly reduced.
    • 本公开公开了一种用于将部件保持在轴上的预紧锁定装置(100),包括:具有第一端面(11)和相对的第二端面(12)的垫圈(1),其中,所述垫圈 所述环安装在所述轴上,其第一端面(11)与待保持的部件紧密接合; 预紧螺母(3),所述预紧螺母(3)螺纹联接在所述轴上,其中所述预紧螺母的一端与所述垫圈(1)的所述第二端面(12)接合; 通过螺纹布置在预紧螺母(3)外部的液压螺母(4),其中液压螺母(4)的环形活塞(5)能够在流体下的垫环(1)上施加作用力 以便在垫环(1)和预紧螺母(3)之间形成间隙; 以及用于填充该间隔的填充构件。 填充部件用于填充间隔,从而可以保持预紧力,这确保了轴上的部件被紧密地保持。 在这种情况下,液压螺母可以被移除,由此成本显着降低。
