Description
Technical field
The utility model relates to a kind of joint structure, especially a kind of swivel coupling.
Background technique
Traditional swivel coupling has number of different types.Some swivel coupling axle center directly contacts with axle sleeve, and moment of rotation is large, poor stability, and friction factor is large, needs frequently to change Sealing or lubricating oil filling lubricating grease.Some swivel coupling key position is by oilless bearing or other bearing touch, and cost is high, and mechanical volume is large, is not really to there is no need to use for when heavy duty high speed.Oiler and the oil outlet of multiple swivel coupling are mutually right angle, can produce considerable influence, thus cause oil pressure uninterruptedly to change when axle sleeve rotates around axle center to the flow rate of medium, may affect machine and run and performance.
It is the swivel coupling of the petroleum conveying pipeline of the model utility bulletin of 201020556416.9 as China Patent No., it comprises socket and spigot, spigot and socket are that plug-in type is connected, its junction plane is provided with annular docking groove, steel ball is filled with in whole docking groove, the socket that docking groove is relative is provided with filling hole, filling hole is provided with plug, socket end and spigot connecting part are provided with seal ring, its advantage is that the voltage endurance capability of device and sealability are better, joint flexible rotation, long service life.But annular docking groove is arranged on spigot and socket junction plane place, processing comparatively bothers; Seal ring is arranged on socket end and spigot connecting part, and oil can infiltrate in the connecting part between spigot and socket, and sealing effect is not ideal enough, and more difficult during as installed seal ring; Steel ball is between plug and docking groove, and when steel ball rolls, steel ball can produce with plug and wear and tear, and adds maintenance cost.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of easy for installation, rotate flexibly, good seal performance and the low swivel coupling of maintenance cost.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of swivel coupling, comprise turning axle core barrel and joint, described joint is provided with connection chamber, described turning axle core barrel is provided with joint, described joint comprises integrated seal section and meander sections, described connection chamber comprises the turned cavities and Seal cage that distribute successively from top to bottom, described seal section is contained in described Seal cage, described meander sections is contained in described turned cavities and described turned cavities is stretched out in the end of described meander sections, described meander sections is provided with the first circular groove and the second circular groove, described seal section is provided with the 3rd circular groove, described first annular slot is in the end of stretching out the meander sections described in turned cavities, screens ring is provided with in the first described circular groove, the second described circular groove is positioned at turned cavities, scroll positioning device is provided with between the second described circular groove and the chamber wall of described turned cavities, the 3rd described circular groove is positioned at described Seal cage, seal arrangement is provided with between the 3rd described circular groove and the chamber wall of described turned cavities, the chamber wall of described turned cavities is provided with for installing scroll positioning device and observing the installation peep hole of inner leakage of oil situation, along the second circular groove described on the direction, medial axis of described turned cavities above described installation peep hole.
Distance range between the center line and the central axis of the second described circular groove of installation peep hole described on the direction, medial axis of described turned cavities is 3mm ~ 5mm.During installation, the second circular groove is alignd with installation peep hole, after scroll positioning device is put into the second circular groove from installation peep hole, turning axle core barrel is upwards mentioned 3mm ~ 5mm and is positioned by screens ring, during actual use, scroll positioning device can not roll out from installation peep hole.
Described scroll positioning device device is made up of around the equally distributed steel ball of described meander sections multiple.Adopt steel ball as scroll positioning device, friction factor is little, and during rotation, moment of rotation is little, is applicable to High Rotation Speed.
Described screens ring is jump ring.Easy for installation and not fragile.
Described seal arrangement comprises seal ring bonded to each other and the back-up ring for stopping impurity inside fluid.Sealing effect is better, not by the impact of fluid when protection turning axle core barrel rotates relative to joint.
Sidewall on described joint between the second described circular groove and the 3rd described circular groove is convex globoidal.When turning axle core barrel rotates relative to joint, the sidewall between the second circular groove and the 3rd circular groove and the friction between the chamber wall of connection chamber reduce greatly.
Dismountable transparent chock plug is provided with in described installation peep hole.When preventing seal arrangement from damaging leakage of oil, fluid spills from installation peep hole.
Compared with prior art, scroll positioning device is provided with between the chamber wall that the utility model has the advantage of the second circular groove and turned cavities, make turning axle core barrel can carry out the rotary motion of 360 ° relative to joint, can meet and oil transportation is carried out to any direction, and ensure that the stability that turning axle core barrel rotates; Turned cavities and Seal cage distribute from top to bottom successively, and fluid, by the seal blocks in Seal cage, is not subject to the impact of fluid when protection turning axle core barrel rotates relative to joint; During installation, the second circular groove is alignd with installation peep hole, after scroll positioning device is put into the second circular groove from installation peep hole, turning axle core barrel is upwards mentioned and snaps in the first circular groove by screens ring, thus turning axle core barrel is positioned, during actual use, scroll positioning device can not roll out from installation peep hole.
