Abstract
The invention provides a waveguide switch with a separating-integrating guide rotor. The waveguide switch comprises a guide rotor and a guide stator. The guide rotor comprises a rotation shaft and a plurality of guide bodies. The plurality of guide bodies are combined to form a body structure of the guide rotor and can move relative to the rotation shaft to enable the rotation gap between the guide rotor and the guide stator to increase or decrease. According to the waveguide switch, the guide rotor outer diameter size is changeable, the outer diameter size is reduced when the guide rotor rotates, the guide system rotation gap is increased, and accordingly, the rotation reliability is improved; when the guide rotor is static, the outer diameter size is increased, the guide system rotation gap is reduced, and accordingly, the microwave transmission performance is improved, the waveguide switch machining cost is reduced, and the reliability is improved.
Description
Technical field
The invention belongs to electric mechanical switch field, particularly relate to a kind of waveguide switch with separating-closing type leading rotor.
Background technology
Waveguide switch is as a kind of electromechanical integration assembly, be mainly used in switching between the selection in microwave signal transmission path, the break-make of waveguide energy or passage, be widely used as the radar of high-power output and the change over switch for subsequent use of communication transmitter, in the Microwave emission equipment being simultaneously also widely used in Satellite Communication System and microwave observing and controlling engineering.The switching being commonly used to realize antenna in the 1:1 backup of core microwave equipment or microwave power signal and unloading between passage is one of critical component of satellite-signal emission system.
Traditional waveguide switch is mainly rotary structure, is made up of electromagnetic system and navigation system.The navigation system of waveguide switch is made up of leading stator and leading rotor, and leading rotor does the rotation of finite angle in the cavity of navigation system, thus realizes the switching of microwave transmission passage.
The problem of prior art is, in order to obtain good microwave transmission performance, the rotary gap between leading rotor and leading stator designs very little, causes that the part processing precision demand of leading stator and leading rotor improves, machine work cost significantly improves.Meanwhile, rotary gap very little making easily interferes in navigation system rotation process, rubs, and causes rotating clamping stagnation.Rotation clamping stagnation is the topmost failure mode of waveguide switch, therefore the reliability of waveguide switch reduces.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of waveguide switch with separating-closing type leading rotor, very little with the gap overcome between leading rotor in waveguide switch of the prior art and leading stator, cause the problem that machine work cost is high, reliability is low.
Technical scheme of the present invention is: the invention provides a kind of waveguide switch with separating-closing type leading rotor, comprises leading rotor and leading stator, and leading rotor comprises rotating shaft and polylith leading main body, and polylith leading body combination forms the agent structure of leading rotor; Polylith leading main body can be moved by relative rotation axi, makes the running clearance between leading rotor and leading stator increase or reduce.
Leading rotor also comprises multiple support bar, and support bar connects on the rotary shaft, and leading main body is slided along support bar respectively.
In polylith leading main body, correspondence arranges electromagnetic assembly; Electromagnetic assembly drives leading bulk motion.
In polylith leading main body, correspondence arranges permanent magnet; Permanent magnet drives leading bulk motion.
Polylith permanent magnet magnetic force repels each other, and drives the counter motion each other of polylith leading main body, the running clearance between leading rotor and leading stator is reduced.
The suction-combining force of electromagnetic assembly "on" position is greater than the opposing magnetic force of permanent magnet, drives polylith leading main body to move toward each other, the running clearance between leading rotor and leading stator is increased.
The present invention's advantage is compared with prior art:
Leading rotor diameter variable dimension of the present invention, when leading rotor rotates, outside dimension reduces, and navigation system running clearance increases, rotation reliability improves, when leading stationary rotor, outside dimension increases, and navigation system running clearance reduces, and microwave transmission performance improves; Thus reduce the machine work cost of waveguide switch, improve reliability.

Embodiment
The invention provides a kind of waveguide switch with separating-closing type leading rotor, be made up of electromagnetic system and navigation system, navigation system is made up of leading stator and leading rotor, and leading rotor comprises rotating shaft, support bar, electromagnetic assembly, permanent magnet, leading main body.
The leading rotor of separating-closing type of the present invention is made up of rotating shaft, support bar, electromagnetic assembly, permanent magnet, leading main body, by the compound action power of electromagnetic assembly and permanent magnet, two lobe leading main bodys to be slided and adhesive, leading rotor diameter reduce when leading rotor needs to rotate along support bar, when leading stationary rotor by electromagnetic assembly and the compound action power of permanent magnet make two lobe leading main bodys along support bar slide and be separated, leading rotor diameter increases.
Shown in Fig. 1, Fig. 2, waveguide switch of the present invention forms primarily of electromagnetic system 1, navigation system 2, wherein navigation system 2 comprises leading rotor b and leading stator a, traditional integral type leading rotor b ' difference shown in leading rotor b and Fig. 3 in the present invention is, traditional leading rotor b ' for integral type inseparable, and leading rotor b of the present invention comprises rotating shaft c, support bar d, electromagnetic assembly e, permanent magnet f, leading main body g; Wherein polylith leading main body g is combined to form the agent structure of leading rotor b, and they can move relative to rotating shaft c, bringing together or separation.
Shown in Figure 4, leading rotor b is the main function components of waveguide switch, comprises rotating shaft c, support bar d, electromagnetic assembly e, permanent magnet f, two lobe leading main body g.Rotating shaft c is support frame and the power-transmitting part of leading rotor, support bar d is the sliding channel of two lobe leading main body g, two lobe leading main body g slide along support bar d relative rotation axi c, the suction-combining force that electromagnetic assembly e produces is the power resources of two lobe leading main body g move toward one another, and permanent magnet f homopolarity is the power resources of two lobe leading main body reverse motions relatively.
Operation principle of the present invention as shown in Figure 5,6, when the leading rotor b of waveguide switch is static in the cavity of leading stator a, electromagnetic assembly e no power, without the suction-combining force, two lobe leading main body g do counter motion along support bar d under the repulsion of permanent magnet f, running clearance h between leading rotor b and leading stator a is reduced, microwave transmission performance optimization.When waveguide switch needs change state, namely when leading rotor b needs to rotate in the cavity of leading stator a, electromagnetic assembly e is energized, produce the suction-combining force, and the suction-combining force is larger than the generation repulsion of permanent magnet f, two lobe leading main body g do move toward one another along support bar d under the effect of making a concerted effort, running clearance h between leading rotor b and leading stator a is increased, and the possibility producing clamping stagnation during rotation reduces, and the reliability of waveguide switch improves.
