Description

A composite slip ring

technical field

The invention relates to a rotary connection device, in particular to a composite slip ring.

Background technique

On rotating equipment, composite slip rings are widely used. For example, electric slip rings are used to transmit power on radar, optical fiber rotary connectors are used to transmit information data, and water hinges are required to transmit cooling fluid to cool the equipment. Considering the factor of installation space, most of the current composite slip rings integrate the three together, that is, the rotary connector and the stator and rotor of the water hinge are generally integrated together. However, it is difficult to disassemble and assemble this integrated composite slip ring. When any slip ring fails, the entire composite slip ring needs to be disassembled, which is very troublesome to operate and extremely poor in maintainability. When adjusting the parameters of a slip ring, it is necessary to redesign the entire compound slip ring, which is very inconvenient to use.

Contents of the invention

The purpose of the present invention is to provide a composite slip ring, which is used to solve the problem of inconvenient use when the existing composite slip ring rotary connector and water hinge are integrated together.

In order to solve the above-mentioned technical problems, the composite slip ring of the present invention adopts the following technical scheme: a composite slip ring includes a rotary connector and a water hinge, the stators of the rotary connector and the water hinge are both sleeved on the outer periphery of the rotor, and the rotating The connector and the water hinge are set separately. The stator of the water hinge is provided with a first water passage, and the rotor of the water hinge is provided with a second water passage that is in communication with the first water passage when it rotates relative to the stator. On the rotor of the connector, there is a first connector on the end facing the water hinge, which transmits the signal of the rotary connector. Two connectors, the stator of the rotary connector and the stator of the water hinge are detachably connected.

There is a certain floating gap in the circumferential direction when the first connector and the second connector are plugged together.

There is a certain floating gap in the radial direction when the first connector and the second connector are inserted.

The rotary connector is a photoelectric hybrid rotary connector, and the first and second connectors are photoelectric hybrid connectors.

The first connector is provided with a guide pin extending toward the second connector, and the second connector is provided with a guide hole that fits with the guide pin guide.

The rotary connector stator and the water hinge stator are detachably connected through flanges provided at opposite ends.

The rotary connector and the water hinge of the composite collector ring of the present invention are arranged separately, and when the rotary connector or the water hinge needs maintenance and replacement, it can be easily disassembled. The stator of the rotary connector and the water hinge can be detachably connected, and the rotor is connected through the first and second connectors. When the parameters of the rotary connector or water hinge change and need to be replaced, only the first and second adapters need to be connected. It only needs to be installed on the two connection ends of the rotary connector and the water hinge respectively, and there is no need to redesign the structures of the rotary connector and the water hinge.

Furthermore, when the first and second connectors are plugged together, there is a certain floating gap in the circumferential direction and the radial direction, and the assembly tolerance can be stably compensated when the rotor of the rotary connector and the rotor of the water hinge transmit torque, absorbing equipment Deformation and deflection, better stability and safety when using.

Further, the cooperation of the first and second connectors through the guide pin and the guide hole can facilitate the plugging process and axial alignment, and at the same time, the guide pin and the guide hole can also play the role of torque transmission.
