The utility model 40 tonnes of tyre type harbours are hung with center-rotary joint, comprise turning axle and be enclosed within the revolving shell on turning axle, end cap is provided with above revolving shell, some axial oil grooves and axial air drain is provided with in turning axle, described turning axle outer wall is provided with some annular oil grooves of being communicated with axial air drain with axial oil groove respectively and annular gas tank, and on revolving shell, be provided with corresponding hydraulic fluid port, each annular oil groove and annular gas tank both sides are provided with high-pressure rotational combined seal ring, annular gas tank is arranged on the top of turning axle, annular oil groove is arranged on the bottom of turning axle, turning axle two ends are provided with support ring groove, support ring is provided with in support ring groove, gas circuit is unified adjusts to top, oil circuit is in below, avoid gas circuit walking in the middle of two high-pressure oil passages, the oil circuit that oil circuit instantaneous pressure causes alters the danger of oil to gas circuit, from the bottom to top, ponding can not flow to enclosure interior to gas circuit entrance pipe, and avoid joint internal rust, two ends are provided with support ring, ensures the coaxality of turning axle and revolving shell, prevents the appearance because of the uneven Leakage caused of Sealing compression.
Turning axle and revolving shell lower end surface of contact are provided with VD dust ring, prevent external dust from entering center-rotary joint inside, ensure oil cleanliness, extend swivel coupling working life.
End cap and turning axle utilize screw to be fixedly connected with, and utilize simple and easy labyrinth seal between end cap and revolving shell, prevent external dust from entering center-rotary joint inside, ensure oil cleanliness, extend swivel coupling working life.
Compared with prior art, the utility model has the advantage of:
1, gas circuit is unified adjusts to top, and oil circuit is in below, and avoid gas circuit walking in the middle of two high-pressure oil passages, the oil circuit that oil circuit instantaneous pressure causes alters the danger of oil to gas circuit; From the bottom to top, ponding can not flow to enclosure interior to gas circuit entrance pipe, avoids joint internal rust; 2, center-rotary joint two ends are provided with support ring, ensure the coaxality of axle and housing, prevent because of the uneven Leakage caused of Sealing compression; 3, all Sealings are assemblied on axle, reduce difficulty of processing, reduce the overall weight of swivel coupling, effectively decrease cost, improve manufacturing efficiency; 4, (one end is VD wiper seal at center-rotary joint two ends; The other end is simple and easy labyrinth seal) increase dustproof construction, prevent external dust from entering center-rotary joint inside, ensure oil cleanliness, extend swivel coupling working life.
