Description
Technical field
The utility model relates to a kind of hydraulic pressure reeler rotary joint device.
Background technology
Modern social development makes rapid progress; Market is also increasingly high to the performance requriements of hydraulic pressure reeler; This just mean must constantly study improve the hydraulic pressure reeler overall performance to satisfy the requirement in market; And SAH is the core texture of hydraulic pressure reeler, and is comparatively complicated, and the each several part action of reeler oil cylinder all will be regulated and could accomplish through SAH.SAH in the market mostly is the normal operation of coming assurance device through higher processing precision, and so doing not only needs expensive processing charges, nor can guarantee the service life of SAH.Under the operating mode of high speed revolution, because rotation mandrel and SAH housing direct contact, the skimming wear of generation can be very serious, causes occurring oil leakage phenomenon, influences the normal operation of hydraulic pressure reeler.Simultaneously, rotation mandrel and SAH housing structure relative complex, tooling cost is higher, and the production cycle is very long, is unfavorable for the processing maintenance.Damage phenomenon if SAH frequently occurs, will influence the work efficiency of hydraulic pressure reeler greatly.In addition, the rotary joint device on the market all is not provided with and unloads oil groove, and this has brought inconvenience when the maintenance washing equipment.
The utility model content
The purpose of the utility model is to provide a kind of hydraulic pressure reeler rotary joint device; Overcome the oil leakage phenomenon of the rotary joint device of hydraulic pressure reeler oil cylinder in the market; Reduce the skimming wear between rotation mandrel and the SAH housing, shortened maintenance cycle, prolonged service life.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme, a kind of hydraulic pressure reeler rotary joint device; Comprise the rotation mandrel that is connected in the SAH housing, offer inlet opening in the rotation mandrel, offer fluid hole on the SAH housing; Offer on the SAH housing and unload oil groove; Offer the circulation groove of UNICOM's inlet opening and fluid hole on the SAH inner walls, between SAH housing leading section and rotation mandrel, be provided with preceding side bearing, between SAH housing tail end and rotation mandrel, be provided with rear end bearing; At SAH housing leading section front end cover is installed; Tail end at the SAH housing is equipped with rear side housing, in the rear end bearing end bearing holdere is installed, and on the inwall of front end cover, is provided with oil sealing; On the SAH inner walls of circulation groove both sides, be provided with axle and use rotary seal ring, be provided with the U-shaped seal groove in rotation mandrel end.
Preferably, said circulation groove is along the circumferential arrangement of SAH inner walls.
After the utility model is installed and used, can stop oil leakage phenomenon, reduce the skimming wear between rotation mandrel and the housing, shorten maintenance cycle, prolong service life.
Description of drawings
Fig. 1: the integral structure scheme drawing of the utility model.
The specific embodiment
As shown in the figure, the utility model mainly by rear side housing 1, rear end bearing 2, SAH housing 3, circulation groove 4, axle with rotary seal ring 5, preceding side bearing 6, front end cover 7, oil sealing 8, inlet opening 9, rotate mandrel 10, U-shaped seal groove 11, bearing holdere 12, fluid hole 13, unload component set-up such as oil groove 14.
A kind of hydraulic pressure reeler rotary joint device; Comprise the rotation mandrel 10 that is connected in the SAH housing 3, offer inlet opening 9 in the rotation mandrel 10, offer fluid hole 13 on the SAH housing 3; Offer on the SAH housing 3 and unload oil groove 14; Offer the circulation groove 4 of UNICOM's inlet opening 9 and fluid hole 13 on SAH housing 3 inwalls, side bearing 6 before between SAH housing 3 leading sections and rotation mandrel 10, being provided with is provided with rear end bearing 2 between SAH housing 3 tail ends and rotation mandrel 10; At SAH housing 3 leading sections front end cover 7 is installed; Tail end at SAH housing 3 is equipped with rear side housing 1, in rear end bearing 2 ends bearing holdere 12 is installed, and on the inwall of front end cover 7, is provided with oil sealing 8; On SAH housing 3 inwalls of circulation groove 4 both sides, be provided with axle with rotary seal ring 5, be provided with U-shaped seal groove 11 in rotation mandrel 10 ends.
Said circulation groove 4 is along the circumferential arrangement of SAH housing 3 inwalls.
The working process of the utility model is following:
During work; Rotation mandrel 10 can rotate in SAH housing 3 with rear end bearing 2 through preceding side bearing 6; Liquid can pick out with fluid hole 13 from the inlet opening 9 of rotation mandrel 10, the circulation groove 4 in the SAH housing 3; On SAH housing 3 inwalls of circulation groove 4 both sides, be provided with axle with rotary seal ring 5, can increase sealing property greatly.Because axle is against on the rotation mandrel 10 after installing with rotary seal ring 5 tightly; Also can reduce to rotate mandrel 10 and SAH housing 3 direct contact probability when rotated; Reduce SAH housing 3 and the wearing and tearing of rotating mandrel 10; Reduce maintenance cycle and tooling cost, prolonged service life.When needing repairing this rotary joint device of cleaning, can use and unload oil groove 14 to reach the effect of quick emptying, convenient and practical.Couple together SAH and oil cylinder with oil pipe and bolt; Can guarantee that like this hydraulic pressure reeler spool tells in the process of rotation, Hydraulic Station is accomplished the action of reel harmomegathus through SAH oil supply oil supply cylinder, in this process; SAH can be guaranteed oil tight; Reduce SAH housing 3 and the skimming wear that rotates mandrel 10, shortened maintenance cycle, prolonged service life.
The above is merely the best specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
