Embodiment
Below in conjunction with accompanying drawing the present invention is made and to further specify.
As shown in Figure 1, 2, the present invention turns round the mandrel 1 of feedway and slip-ring body 2 by Placements such as bolt and welding, be separately fixed at the fixed mechanism of machinery and on the swirl gear that fixed block rotates, 1 of slip-ring body 2 lower end surfaces and mandrel are provided with lower copper packing ring 11, the upper and lower end face of lower copper packing ring 11 respectively processes an annular groove 12 to deposit seal ring, make slip-ring body 2 lower end surfaces and mandrel 1 form end face seal, prevent that hydraulic oil from leaking outside; The interval has seal groove on slip-ring body 2 inner peripheral surfaces, is inlaid with rotary seal 3 in the seal groove, has annular delivery chute 10 between seal groove, has the attachment hole 13 that communicates with delivery chute at described delivery chute 10 corresponding slip-ring bodies 2; In mandrel 1, be provided with transfer passage 15, described transfer passage 15 1 ends link to each other with conveyance conduit to be connected, the other end 14 connects with described delivery chute 10, shown in the figure be, each delivery chute 10 corresponding transfer passage 15, between each transfer passage 15, do not connect mutually, reach each conveyance conduit with different pressures, speed is carried, it should be noted that, another kind of structural type as the present embodiment, transfer passage 15 can be one, and the one end links to each other with conveyance conduit to be connected, and the other end 14 connects respectively with all delivery chutes 10, can reduce like this difficulty of processing of mandrel, make external connection more convenient, fast, have the attachment hole 13 that communicates with delivery chute at each delivery chute 10 corresponding slip-ring body 2.
When the swirl gear of machinery rotates, driving slip-ring body 2 rotates together, because the existence of delivery chute 10, corresponding attachment hole 13 is any position of 360 ° on the transfer passage 15 of mandrel 1 and the slip-ring body 2, all the time all be in the state of connection, the rotary seal 3 of delivery chute 10 both sides guarantees that the working medium in the delivery chute 10 does not leak.For the present invention is further optimized, mandrel at mandrel 1 and the other end of slip-ring body 2 end part seals is processed with screw thread, be fixed by locking nut 5 and 4 pairs of slip-ring bodies 2 of lock washer, can produce vibrations to slip-ring body 2 during swirl gear work, locking nut 5, lock washer 4 play locking effect, guarantee that the present invention turns round feedway and normally moves; Take into account the leakage of working medium, between lock washer 4 and slip-ring body 2, be added with the upper copper packing ring 6 that has ring packing groove 7, be embedded with seal ring in the groove 7.
Bear larger working pressure for making the present invention turn round feedway, between described mandrel 1, slip-ring body 2, slip-ring body 2 two ends that are positioned at the described rotary seal outside are respectively equipped with wear ring 9 and/or single acting piston envelope 8 it are sealed, thereby realize non-contacting oil film seal, reduce friction, prolonged working life; As shown in Figure 3 and Figure 4, be fixedly connected with base 16 by modes such as welding on the outer peripheral surface of slip-ring body 2, base 16 is provided with bolt hole 17, turns round the scene mounting or dismounting of feedway to make things convenient for the present invention.
The present invention turns round feedway and successfully solved the problem that the multi-pipeline working medium is carried from the fixed mechanism to the swirl gear, and its dispensing pressure can reach 0 ~ 41Mpa, interface caliber scope ￠ 6 ~ ￠ 80mm; The present invention adopts the combination seal forms such as bidirectional piston envelope, single acting piston envelope, rotary seal, wear ring, O type circle to seal, and has improved wear resistance, resistance to pressure, osmotic-pressure-tolerant, sealing; Have the characteristics such as simple in structure, with low cost, reliable operation.
The present embodiment for simplicity with offer sealed groove on the slip-ring body, delivery chute describes, in fact, no matter at slip-ring body inner peripheral surface or mandrel outer peripheral surface, as long as between slip-ring body and mandrel, process sealed groove, delivery chute, all can reach beneficial effect of the present invention.
Above embodiment's description is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
