Abstract
The utility model relates to a hydraulic rotating joint for an airplane, which comprises a shaft bushing nozzle (1), a connection clamping pin (2), a shaft nozzle (3), a sealing rubber ring (4) and a sealing retainer ring (5). The shaft nozzle (3) comprises a thread nozzle portion (31) and a shaft rod portion (32), the thread nozzle portion (31) is provided with an inner hole matched with the shaft rod portion (32), and the shaft bushing nozzle (1) is movably connected with the shaft nozzle (3) through the connection clamping pin (2). The shaft rod portion (32) is provided with a sealing groove, and the sealing rubber ring (4) is installed on the sealing groove. The movable connection between the shaft bushing nozzle (1) and the shaft nozzle (3) replaces the original integral connection, thereby being capable of reducing intermediate transforming of pipelines and hoses, changing of movement directions and bending range of the hoses in moving and prolonging service life of the hoses. The sealing rubber ring (4) and the sealing retainer ring (5) are used for seal, thereby being capable of avoiding leakage of hydraulic oil and reducing frictional torsion in rotation.
Description
Technical field
The utility model relates to a kind of swivel, and especially aircraft is used hydraulic rotating joint.
Background technique
There is following problem and shortage in the connection of plane hydraulic system activation part hydraulic pressure ozzle pipeline:
Plane hydraulic system start position uses hydraulic hose to come the displacement at start position is compensated usually.But because the narrow limitation of hydraulic hose installation requirement, to not in same plane, and the big hydraulic interface of relative movement amplitude, it is also infeasible to adopt hydraulic hose to compensate.
Hydraulic rotating joint can be same plane with the conversion of motion of the hydraulic interface in same plane not, has improved the user mode of flexible pipe, prolongs hose life.
Summary of the invention
To the deficiency that the connection of plane hydraulic system activation part hydraulic pressure ozzle pipeline exists, improve the flexible pipe working state, make following creative invention:
1. for the connectivity problem of transformed space motion hydraulic interface, reduce intermediate conversion pipeline and flexible pipe, designed two kinds of typical ozzle directions hydraulic rotating joint of 90 ° and 180 ° each other.
2. adopt general navigation mark hydraulic seal structure, but butt joint internal seal structure size has been carried out optimal design, to satisfy the requirement of joint low temperature seal property and low moment of rotation.
The technological scheme that the utility model is taked is: a kind of aircraft comprises axle sleeve ozzle [1], connects bayonet lock [2], central siphon mouth [3] with hydraulic rotating joint; Central siphon mouth [3] comprises threaded pipe mouth portion [31] and shaft portion [32]; Axle sleeve ozzle [1] has the endoporus that matches with shaft portion [32]; Axle sleeve ozzle [1] flexibly connects through bayonet lock [2] with central siphon mouth [3], and shaft portion [32] is provided with seal groove [6], and seal groove [6] is equipped with O-ring seal [4].
For better implement the utility model, Sealing shield ring [5] is installed in the above-mentioned seal groove [6].
The good effect that the utility model produces: axle sleeve ozzle [1] is connected by original one with central siphon mouth [3] and becomes being rotationally connected of the utility model; Can reduce intermediate conversion pipeline and flexible pipe; Moving direction is carried out conversion; Crooked amplitude when having reduced hose movement, the work working life of having improved flexible pipe greatly; Take O-ring seal [4] and Sealing shield ring [5] to seal, preventing the leakage of hydraulic oil, and the friction torque can reduce to rotate the time.

Embodiment
Below in conjunction with Figure of description the utility model is described in further detail.
Swivel comprises axle sleeve ozzle 1, connects bayonet lock 2, central siphon mouth 3; Central siphon mouth 3 comprises threaded pipe mouth portion 31, shaft portion 32; Axle sleeve ozzle 1 has the endoporus that matches with shaft portion 32; Axle sleeve ozzle 1 flexibly connects through bayonet lock 2 with central siphon mouth 3, is provided with seal groove 6 in shaft portion 32, and O-ring seal 4 is installed in the seal groove 6.
For better implement the utility model, in the above-mentioned seal groove 6 Sealing shield ring 5 is installed.
Embodiment one
When Fig. 1 is an axle sleeve ozzle 1 with 3 one-tenth 180 ° in central siphon mouth, the swivel generalized section, Fig. 3 is its schematic perspective view.Swivel comprises axle sleeve ozzle 1, connects bayonet lock 2, central siphon mouth 3, O-ring seal 4; Central siphon mouth 3 comprises threaded pipe mouth portion 31, shaft portion 32; Axle sleeve ozzle 1 has the endoporus that matches with shaft portion 32; Axle sleeve ozzle 1 flexibly connects through bayonet lock 2 with central siphon mouth 3, is provided with seal groove 6 in shaft portion 32, and O-ring seal 4 is installed in the seal groove 6.
As the utility model one preferred embodiments, in the above-mentioned seal groove 6 Sealing shield ring 5 is installed.
Axle sleeve ozzle 1 is fixed on the housing construction, and axle sleeve ozzle 1 is connected with metal catheter, and central siphon mouth 3 connects the flexible pipe that links to each other with actuator, when actuator is moved, and the servo-actuated of actuator flexible pipe, the central siphon mouth 3 that is connected with flexible pipe is also followed rotation.
Embodiment two
When Fig. 2 is an axle sleeve ozzle 1 with 3 one-tenth 90 ° in central siphon mouth, the swivel generalized section, Fig. 3 is its schematic perspective view, its mounting type, working procedure is similar with embodiment one.
Technique effect: the axle sleeve ozzle is connected by existing fixed with the central siphon mouth and becomes being rotationally connected of the utility model; Can reduce intermediate conversion pipeline and flexible pipe; Moving direction is carried out conversion, reduced the crooked amplitude of flexible pipe, improved the work working life of flexible pipe greatly; And take O-ring seal and Sealing shield ring to significantly reduce the leakage of hydraulic oil.
The utility model aircraft is used hydraulic rotating joint; Not only can be used for aircraft; Can also be used for other hydraulic actuation field, to connection that needs transformed space motion hydraulic interface and the occasion that the flexible pipe installment state is had relatively high expectations, all within the protection domain of the utility model.
