Description

A kind of novel multi-channel rotary joint
Technical field
The present invention relates to a kind of novel multi-channel rotary joints, belong to airplane hydraulic pressure technical field.
Background technology
Rotary joint is that the connection that fluid media (medium) liquid, gas etc. are input to from static duct in slewing seals dress It puts.During existing undercarriage folding and unfolding, for mainly carrying out oil circuit transmission with hose, but for undercarriage at movement When movement locus is more complicated, hose can not avoid the movement torsion problem generated;Additionally, due to aircraft remaining backup requirements, It needs to transmit a plurality of oil circuit in undercarriage motion process, existing rotary joint cannot meet aircraft high pressure and multichannel demand.
Invention content
The purpose of the present invention is overcoming the deficiencies in the prior art, a kind of novel multi-channel rotary joint is provided, is used Oil circuit transmission problem in complicated undercarriage movement locus, leads to oil and sealing effect is good, solves and selects hydraulic hose movement Torsion problem in the process.
The novel multi-channel rotary joint of the present invention, for being transmitted to a plurality of oil circuit, including rotary body and set casing Body is equipped with union elbow on rotary body, and several free flow couplings are equipped in fixed shell, and the rotary body includes integral type Connector connecting seat and rotary shaft, the rotary shaft there is oil outlet in axial different location, connecing on the connector connecting seat Mouth is connected with corresponding oil outlet by internal oil passages;There is spaced seal groove and oil groove in the fixed shell, Sealing ring is installed in seal groove, the rotary shaft is inserted into so as to which each oil groove be isolated in sealing ring, and the oil outlet with it is each From oil groove correspond to connection;Each oil groove is connected by the oil circuit inside fixed shell with several free flow couplings.
Further, cover board is installed in the outer end of the fixed shell, by screw by the rotary body and set casing Body connects.
Further, the free flow coupling and union elbow are fixed respectively by locking nut.
Further, on the rotary body and the joint face of fixed shell and on the joint face of fixed shell and cover board Plastics baffle ring is installed.
Further, it is locking by lead sealing between the screw.
Further, there is the blocking of sealing oil circuit in the outer end of the connector connecting seat.
Further, the quantity of the free flow coupling and union elbow is 4 groups.
A kind of novel multi-channel rotary joint provided by the present invention is the high-pressure and hydraulic rotation for Multi-oil circuit rotary transfer Adapter, good airproof performance, string oil mass is small between each oil circuit, external No leakage, ensures the Multi-oil circuit of undercarriage motion process Transmitting.
Description of the drawings
Fig. 1 is the structure diagram of Multi-channel rotating joint of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the oblique view of fixed shell;
Fig. 5 is the oblique view of rotary body.
Specific embodiment
With reference to specific attached drawing, the invention will be further described.
Multi-channel rotating joint includes rotary body 1, fixed shell 2, sealing ring 3, cover board 4, screw 5, locking nut 6, straight Connection for bbreather pipe 7, locking nut 12, plastics baffle ring 13, lead sealing 14, blocks 15 etc. at union elbow 8~11.
As shown in Figure 1, the present invention includes rotary body 1 and fixed shell 2;The rotary body 1 is provided with different size everywhere Union elbow 8~11, for realizing four oil circuits arrangement in a limited space, union elbow 8~11 passes through locking nut 12 Fitted seal circle is fixed on rotary body 1;Rotary body 1 can be fixed on by four screws on moving component, follow moving component Realize 360 ° of movements;Free flow coupling 7 everywhere are set in 1 fixed shell 2 of rotary body, for connecting four oil circuits;The fixation The end face of housing 2 is equipped with cover board 4, is fixed in fixed shell 2 by screw 5 at three, is set between cover board 4 and fixed shell 2 Plastics baffle ring 13 enters valve inner for completely cutting off external contamination;2 relative rotation body 1 of fixed shell is static;It is set in fixed shell 2 It puts annular groove at 9 and is respectively used to during exercise the sealing between unicom oil circuit and oil circuit always, prevent string oil.
As shown in Fig. 2, at screw 5 set lead sealing move it is locking.
As shown in figure 3, the rotary body 1 sets four through-holes in circumferencial direction, and is sealed with blocking 15.
The rotary body 1 and fixed shell 2 are using clearance seal, and good airproof performance, leakage rate is low, and hydraulic work system is steady It is fixed, reliable.
The present invention operation principle and the course of work, as shown in Figure 1, fluid media (medium) such as hydraulic oil by oil inlet ozzle 8~ 11 enter rotary body 1, and the annular groove for flowing into fixed shell 2 is exported via rotary body 1, when rotary body 1 and fixed shell 2 are opposite During rotation, fluid is remained to be connected with coming oil, is excluded via four road free flow couplings 7;Because rotary body 1 and fixed shell 2 Using clearance seal, a small amount of string oil is had between four oil circuits.2 contact surface of rotary body 1 and fixed shell, fixed shell 2 and lid 4 contact surface of plate is equipped with plastics baffle ring 13, and for moving when prevents foreign from entering accessory internal, and prevent the contact surface Mutually abrasion.
