Description

Magnetostrictive resonators are known in which resonant rods are fixed at a nodal point, and the excitation coils are placed on two frames. In such devices, the magnetization is produced by permanent magnets, and the tuning of the oscillation frequency is achieved with the help of oxypher cores. However, the known resonators have low electromechanical parameters.

In the described invention, in order to improve the electromechanical parameters of the resonator, tubular permanent magnets with oxypher trimmers are used, which ensures a uniform magnetizing field in the resonant rod and high electromechanical parameters of the resonator.

The design of the magnetostrictive resonator is shown in the drawing.

A resilient washer 2 is put on the resonant rod / of the oxypher at the nodal point of the oscillations of the rod. A rod with a washer is clamped between the frames 3 of the excitation coils. One half of the frame is provided with a socket where the elastic washer is placed. The second half of the frame is screwed into the first half and clamps the washer 2, keeping the rod in a fixed position relative to the frame of the coil. Similar to the mounting structure of the rod has high electromechanical parameters (quality factor, the coefficient of electromechanical communication of the rod and the excitation coil). On the frame 3, there is Eistup, which is clamped by two tubular magnets 4 w. 5. The magnets have slots for providing a fixed position of the magnets relative to the coil frame.

Tubular magnets provide a uniform constant field in the resonator rod. An oxypher washer 6 is placed on the magnets, with a hole B of which is fitted with a trimmer 7, which allows the frequency of the resonator to be set to an accuracy of + 1 Hz. The magnets with the coil and the rod are located in the corneus 8. The output clamps are fixed on the sleeve 9, which is pressed against the case by the cover 10.

The described resonator can be used in filters, oscillator circuits, correction circuits, etc.
