SLIP RING INSTALLED BETWEEN A BODY AND A ROTATING TURRET}

The present invention relates to a slip ring assembly for a body-turret designed to continuously supply turrets and to continuously supply electric circuits between the body and the rotating turret, high pressure oil and low pressure filtered air.

Typically, slip rings include radar posts, turrets of tanks and self-propelled guns, heavy construction equipment, various industrial machinery, aviation equipment, electronic tracking devices, missile launchers, helicopter rotors, centrifuges, ultrasonic detectors. It is used to supply electricity or hydraulic pressure stably at high speeds such as wind turbine generators.

However, most of the slip rings used in such equipment generate a lot of noise due to friction during operation, and because the structure is complicated, manufacturing is difficult and the manufacturing cost increases accordingly.

The present invention for solving the above problems can improve the quietness by reducing the noise generated during friction, and the vehicle body designed to stably supply electric circuits, high pressure fluid and low pressure air to the rotating part It is an object to provide a slip ring assembly for a turret.

In order to achieve the above object, the body- turret slip ring assembly of the present invention includes a rotor rotatably disposed, and an upper manifold and a lower portion disposed at both ends of the tube and having hydraulic pressure flowing through upper and lower passages, respectively. A manifold, an upper body and a lower body coupled to the upper manifold and a lower manifold, respectively, and disposed between the upper body and the lower body, and having an intermediate body having an inner cylinder and providing a pneumatic passage therein. It is characterized by.

Hereinafter, with reference to the accompanying drawings will be described a slip ring assembly for a vehicle body turret according to a preferred embodiment of the present invention.

1 is a cross-sectional view showing the configuration of a slip ring according to the present invention, Figures 2 and 3 are side views, respectively, seen in the II and III direction of Figure 1, Figure 4 is a side view of the slip ring seen from another angle, FIG. 5 is a cross-sectional view taken along the line VV of FIG. 1.

As shown in these figures, the slip ring 1 according to the present invention is roughly provided with a tube rotatably mounted in the center, a bearing for rotatably supporting the brush block set and the upper manifold and a protective film for airtightness. It consists of. In addition, the slip ring is designed to continuously supply low-pressure air filtered between the turret cover of the tank and the rotating turret, as well as the electric circuit and high pressure fluid.

To this end, the slip ring 1 of the present invention includes a pneumatic inlet 12 and a pneumatic outlet 14 through which low pressure air flows in and out, a hydraulic supply inlet 18 through which high pressure fluid flows in and out, and a hydraulic pressure. Along with the return outlet 16, a plurality of electronic connectors 24 and 26 are provided. Plugs 20 and 22 are fitted into the hydraulic supply inlet 18 and the hydraulic return outlet 16.

Next, as shown in Fig. 5, when the configuration of the slip ring 1 according to the present invention, the tube 30 is rotatably arranged, and are disposed at both ends of the tube 30, respectively, the upper passage ( 70 and the upper manifold 32 and the lower manifold 42, through which hydraulic pressure flows through the lower passage 72, and the upper body coupled to the upper manifold 32 and the lower manifold 42, respectively. 50) and an intermediate body 52 disposed between the lower body 54 and these upper body 50 and the lower body 54, and providing a pneumatic passage 80 together with an inner cylindrical body 82 inside. Consists of

Here, the upper manifold 32 is rotatably supported by many bearings, and the tube 30 is fitted inside. In addition, brush block sets 56, 58, and 60 constituting the electric arc were formed to provide a protective film. A hydraulic sealing seal 46 is sandwiched between the tube 30 and the lower manifold 72, and a pneumatic sealing seal 62 for a similar purpose is sandwiched between the intermediate body 52 and the lower body 54.

The upper manifold 32 and the lower manifold 42 are covered with covers 34 and 44 for preventing the separation of the bearings and preventing the inflow of foreign substances.

In the slip ring 1 having such a configuration, while the upper manifold 32 rotates, the low pressure air is stably introduced and discharged through the pneumatic inlet 12 and the pneumatic outlet 14, and at the same time, the hydraulic supply inlet is provided. The high pressure fluid is stably supplied to the rotary turret through the 18 and the hydraulic return outlet 16. Similarly, it is stably supplied from the vehicle body to the rotating turret through a plurality of electronic connectors 24 and 26.

According to the present invention described above, it is possible to improve the quietness by reducing the noise generated during friction, and there is an advantage that the high-pressure fluid, including the electrical circuit, can be stably supplied to the rotating part of the low-pressure air or the like.
