본 고안은 건설용 중장비의 유압터닝 조인트에 관한 것으로, 더욱 상세하게는 굴삭기나 기중기등과 같이 상부와 하부로 분리되어 선회하는 장비의 상, 하부에 작동유를 공급하는 경우 유압터닝 조인트의 유로배열을 수평방향으로 형성시킴으로서 패킹이 장착되는 허브의 결합홈이 용이하게 기계가공 됨으로서 제품의 성능이 향상될 수 있도록 한 유압터닝 조인트에 관한 것이다.The present invention relates to a hydraulic turning joint of heavy equipment for construction, and more particularly, when the hydraulic oil is supplied to the upper and lower parts of the turning equipment, such as an excavator or a crane, which is divided into upper and lower parts, the flow path arrangement of the hydraulic turning joint is The present invention relates to a hydraulic turning joint for improving the performance of a product by easily forming a coupling groove of a hub on which a packing is mounted by forming in a horizontal direction.

종래의 유압터닝 조인트는 제1a, b도에 나타낸 바와같이, 수직방향의 유로(油路)를 확보하기 위해 유압터닝 조인트의 원통형인 축(1)과 허브(2)를 결합시켜 축(1)에 형성된 주입구(a, b, c, d, e)와 허브에 형성된 배출구(1a, 1b, 1c, 1d, 1e)를 상호 연통되도록 결합시키되, 허브(2)에 형성된 배출구(1a, 1b, 1c, 1d, 1e)들 사이에는 원형의 패킹홈(2a, 2b, 2kc, 2d, 2e, 2f)이 형성되어 패킹(3a, 3b, 3c, 3d, 3e, 3f)이 장착된 것이다.In the conventional hydraulic turning joint, as shown in FIGS. 1A and 1B, the cylindrical shaft 1 of the hydraulic turning joint and the hub 2 are coupled to each other to secure a vertical flow path. Injecting holes (a, b, c, d, e) formed in the outlet and the outlet (1a, 1b, 1c, 1d, 1e) formed in the hub are coupled to each other, the outlet (1a, 1b, 1c formed in the hub 2) , 1d, 1e are circular packing grooves 2a, 2b, 2kc, 2d, 2e, and 2f to form packings 3a, 3b, 3c, 3d, 3e, and 3f.

상기와 같은 유압터닝 조인트는 이들의 직경보다 길이가 상대적으로 길게 형성됨으로서 장비에 장착시키는 경우 장착공간이 협소하여 장착작업이 용이하지 못하고, 축(1)과 결합하는 허브(2)의 내주연을 기계가공하는 경우 이의 직경보다 길이가 상대적으로 길어 허브(2)의 상단부나 하단부를 통하여 한번의 작업으로서 마무리 작업이 이루어지지 않아. 허브(2)의 양단부에서 시작하여 중앙에서 마무리작업을 하게되므로 내주연의 표면정도가 떨어지며 이의 진원도를 맞추기 위해 소요되는 작업시간이 길어져 작업능률이 저하되며, 상기 내주연에 형성된 패킹(3a, 3b, 3c, 3d, 3e, 3f)이 장착되는 패킹홈(2a, 2b, 2c, 2d, 2e, 2f)의 가공상태가 불량하여 패킹(3a, 3b, 3c, 3d, 3e, 3f)의 밀봉작용이 제대로 이루어지지 않아 제품의 신뢰성이 떨어지는 문제점을 가지는 것이었다.Since the hydraulic turning joints are formed to be relatively longer in length than their diameters, the mounting space is narrow when mounting to the equipment, and thus the mounting work is not easy, and the inner circumference of the hub 2 coupled with the shaft 1 is not easily installed. In the case of machining, the length is relatively longer than its diameter so that the finishing work is not done as one operation through the upper end or the lower end of the hub 2. Starting from both ends of the hub (2) is finished in the center, so the surface of the inner circumference decreases and the working time required to match the roundness is long, resulting in a decrease in work efficiency, and the packings formed on the inner circumference (3a, 3b). Sealing of the packings 3a, 3b, 3c, 3d, 3e, and 3f due to poor machining conditions of the packing grooves 2a, 2b, 2c, 2d, 2e, and 2f to which 3c, 3d, 3e, and 3f are mounted. This was not done properly had a problem of low reliability of the product.
