Definitions

  • the invention relates to a waveguide switch with a housing, on the circumference of which at least two waveguide connections are provided and a rotor arranged in the housing which contains at least one waveguide element for connecting the at least two waveguide connections in a specific rotor position, a motor for driving the rotor and a locking member is provided for fixing the rotor in a specific rotor position.
  • a waveguide switch with four waveguide connections and a rotor, which has three waveguide connecting paths, is known.
  • the switch enables a cross connection for two RF signals to be connected simultaneously when the rotor is in a first or middle position. There are also two positions that differ by 45 °, in which two adjacent connection points are connected to each other.
  • a stepper motor is provided for rotating the switch, which rotates the rotor into the switch positions. Locking elements, for example screws, are used to determine the position of the rotor.
  • the object of the invention is to provide a waveguide switch in which the rotor is turned into the switching positions with high accuracy and with a short switching time and electrical losses are avoided.
  • This object is achieved in that - by means of the motor, the rotor is rotated close to the desired rotor position and the locking member is designed such that it rotates the rotor into the specific rotor position by means of magnetic attraction forces.
  • the invention ensures that the rotor does not swing into the specific rotor position or switch position and is locked after the end of the transient process, but is moved into the switch position by the motor due to the magnetic attraction forces and at the same time is locked by the generated forces.
  • the latching element in the manner of a rocker arm which is held in the tilted position by means of an electromagnet during a rotor movement caused by the motor.
  • the easiest way to do this is that the motor is connected in series with the electromagnet and a motor current flows until the rocker arm is tilted out of the locked position.
  • the motor current is switched off, ie when it is reached the position predetermined by the control of the motor - as a motor, for example, a stepping motor or a simple torque sensor is advantageous - the locking member tilts into the locking position by spring force, so that magnetic attraction forces can be effective.
  • the rotor can only be fixed using magnetic attraction forces are carried out.
  • permanent magnets or a permanent magnet and a yoke moment are arranged radially opposite one another on the rotor and stator and separated by the air gap. If the rotor is brought into a position in which there is mutual attraction between the magnetic parts of the rotor and the stator, then the magnetic forces bring about an exact alignment of the rotor in the desired position.
  • several magnets on the circumference several positions of the rotor can be fixed in this way.
  • a modular structure in order to adapt any components and thus to ensure high accuracy in every application and, for example, to significantly simplify the replacement of a component.
  • a storage unit as an individual component.
  • This bearing unit serves the switch unit as a rotor bearing, and the drive motor or its rotor part can also be attached to this bearing unit.
  • a particular advantage of the invention is also seen in coupling additional switch parts to the switch part by means of adapter surfaces, which switch parts are then switched simultaneously with a drive motor.
  • a waveguide switch as shown in Fig. 1 has the task of connecting or disconnecting different waveguide paths and is required, for example, to switch reserve microwave devices in a system to replace a defective device if such a measure for reasons of Operational security is required. For safety reasons, there is a need to provide reserve devices that can be put into operation by means of waveguide switches, particularly in the case of spacecraft.
  • the waveguide switch consists of a housing 1 with four symmetrically arranged waveguide inputs AD.
  • a rotor 2 arranged in the housing is rotatably arranged in the housing and has three waveguide passages.
  • switch housing 1 In order to combine the inputs as required, four switch positions I-IV are required, with the inputs AC in position I, the inputs AB and CD in position II, the inputs BD in position III and the inputs BC, AD in position IY. Due to the cube-shaped design of the switch housing 1 can several switches can be coupled in any way, so that any switching combination can be realized. It has been shown that a high positional accuracy of the rotor is required to achieve low transmission losses. Conventional stepper motors do not show the required accuracy due to the step angle hysteresis. A locking member is therefore used to lock the rotor in a switching position, the basic structure of which is shown in FIG. 2.
  • the latching element 3 works in the manner of a magnetic switch and consists of a U-shaped iron core 4 with a coil 5 fastened to the housing 1.
  • the cross spring joint 6 is a friction-free and play-free bearing, which simultaneously generates a return spring force and moves the yoke 4 against a stop in the position shown.
  • the rotor 2, which is not shown here, is locked in the de-energized state, ie in the position shown.
  • the coil 5 is supplied with current, as a result of which the yoke 7 is attracted and the rotor is released.
  • Fig. 3 the locking of the rotor 2 is shown in more detail.
  • the rotor 2 is shown here in a detail with two position stops or cams 8, 9. These cams consist of a base body 38, a magnetic plate 10 made of a permanent magnetic material and an impact plate 11.
  • cams 8 consist of a base body 38, a magnetic plate 10 made of a permanent magnetic material and an impact plate 11.
  • the yoke 7 is shown in this position. Switching off the stepper motor simultaneously switches off the coil 5, causing the yoke to close is next moved in the radial direction by the cross spring joint.
  • the rotor rotates in the direction of the yoke until it bears against the impact plate. This ensures that the switch position is reached with high accuracy.
  • the rotor 2 is turned further into a new switching position by switching on the coil 5, whereupon the yoke 7 is tightened in the radial direction and releases the rotor 2. It can be seen that for this purpose not a force corresponding to the attractive force of the magnetic plate 10, but only the corresponding shear force must be applied in order to move the yoke 7.
  • the stepper motor then turns the rotor close to the new switching position.
  • the stepping motor 14 consists of stator-side motor coils 16 which are distributed over the circumference of the stator in such a way that when a specific motor coil is actuated, the rotor is rotated into one of the switch positions assigned to it.
  • a pair of coils can also be provided and the motor magnet 17 arranged on the rotor can be designed with two poles with an axial direction of magnetization. In the first case, the motor magnet 17 consists of an axially directed permanent magnet.
  • the motor coils 16 are applied to a yoke carrier 18.
  • the yoke carrier 18 is mounted with fastening elements 19 on a housing cover 20, which in turn is arranged on the end face of the housing 1.
  • -Di-e rotor bearing 12, 13 is machined with deep groove ball bearing provides the interposition of bearing sleeves 21, 22 are pushed onto axle pieces of the rotor and are biased via an adjusting nut 23.
  • the latching element is connected to the stator by means of locating pins 24, 25. This ensures an exact assignment to the switch positions.
  • FIG. 5 An alternative embodiment of the detent by means of a rocker arm is shown in FIG. 5.
  • a waveguide rotor arrangement with a magnetic detent is shown.
  • the rotor body 26 is fastened in a known manner by means of a bearing in the stator body 27.
  • the HF channels as well as the bearing and the motor for rotating the rotor body are not shown in this top view.
  • the rotor body carries a permanent magnet 28 which is surrounded by a yoke part 29.
  • a first inference element 30 and a further inference element 31 are arranged on the stator. In the position shown here, the yoke element 30 with the yoke part 29 forms a closed magnetic circuit which is only interrupted by the air gap between the rotor body 26 and the stator body 27.
  • a further yoke element 31 which is arranged at 45 ° to the first one, enables the rotor body 26 to be set in a position rotated at 45 ° to the starting position.
  • the rotor body is rotated in a known manner.
  • the drive torque of the motor must overcome the pull-off torque of the permanent magnet 28.
  • the end stops 32, 33 are also constructed to be magnetically active and each have a permanent magnet which exerts an attractive force on the rotor as soon as it is located with one of the ferromagnetic yoke plates in the vicinity of the permanent magnets.
  • the exact assignment of the rotor position to the stator is given when one of the yoke plates 34 or 35 rests on one of the stop surfaces 36 or 37.
  • the rotor body 26 can thus be moved into four defined positions.
  • the number of switch positions is variable, as is the angle of rotation. In the example shown here, the positions 0 °, 45 °, 90 ° and -45 ° can be fixed.
  • the modular waveguide switch shown in FIG. 6 consists of the switch unit 101, the detailed structure of which is known from the main patent, the motor 102 and the bearing unit 103, which is arranged between the motor and the switch unit.
  • the motor is designed so that it encloses the bearing unit, of course, a simple axial connection of the components is also conceivable. If a further switch unit 104 is to be switched with the same motor, it can be attached to the end face of the switch unit 101.
  • the bearing unit 103 can contain both ball bearings and another form of storage. A decisive factor when mounting a waveguide switch is above all a low static friction and a low bearing torque in order to ensure the necessary accuracy.
  • FIG. 7 shows the individual components in a detailed design.
  • the switch part 101 consists of the housing 105, which is provided with the corresponding waveguide openings, the rotor 106 located therein and a front cover 107.
  • the rotor has a pin-shaped extension 108, which effects the adaptation with the bearing unit 103.
  • the bearing unit 103 consists of a bearing housing 109, a bearing ring 110, axially clamped shoulder ball bearings 111, 112, a shaft 113 and a clamping ring 114.
  • the motor 102 consists of the stator part 116 with the coil carrier 117 and the coils 118.
  • the stator part is fastened within a cup-shaped opening in the bearing housing 109.
  • the rotor part 119 of the motor 102 consists of a magnetic carrier 120 and permanent magnetic segments 121.
  • the rotor part 119 is fastened directly on the shaft 113 of the bearing unit 113 by means of a screw connection 122.
  • the arrangement of the coils 118 and the segments 121 and the actuation of the coils is described in the main patent and need not be explained in more detail here.
  • the motor 102 and the bearing unit 103 are closed on the front side with a cover plate 123 and thus effectively protected against external influences.
  • the modular design of the waveguide switch makes it easy to replace the individual elements without losing accuracy.
  • the switch can be adapted to any application by selecting the individual elements.
