Abstract
The utility model discloses a differential transformer structure. The differential transformer structure comprises a hollow coil framework, wherein a differential transformer is arranged on the coil framework; the differential transformer structure also comprises a rotating shaft which is rotationally and glidingly installed in the coil framework; mounting holes are respectively formed in two ends of the rotating shaft; an iron core is eccentrically installed on the rotating shaft positioned on a shaft section in the coil framework. The differential transformer structure can be used for measuring rotation and axial movement information of the rotating shaft, is high in measurement accuracy, and has good measuring sensitivity.
Description
Technical field
The utility model relates to field transformer, is specially a kind of differential transformer structure.
Background technology
Differential transformer is a kind of transformer device structure commonly used, and it oppositely is connected in series secondary coil, between primary and secondary coil, iron core is set, and can be used for measuring the mobile displacement information that waits of iron core.Differential transformer can be used for static measurement, also can be used for kinetic measurement, has advantages of highly sensitive.But the differential transformer structure of still for rotation and the axial endplay of rotation axis, not measuring.
The utility model content
The purpose of this utility model is to provide a kind of differential transformer structure, and prior art is not rotated rotation axis and the problem of the differential transformer that axial endplay is measured to solve.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
a kind of differential transformer structure, include hollow coil rack, and the insulation sides seat that is connected to the coil rack two ends, it is characterized in that: in the middle of on described coil rack, position is wound with primary coil, be wound with respectively secondary coil on the coil rack on primary coil both sides, twice the level coil forms differential transformer with primary coil after differential concatenation each other, also include the rotating shaft of rotating and being slidably mounted in coil rack, stretch out from both sides insulation sides seat respectively at described rotating shaft two ends, and the rotating shaft two ends are respectively equipped with installing hole, described rotating shaft is positioned at bias on the shaft part of coil rack iron core is installed.
Described a kind of differential transformer structure is characterized in that: be respectively arranged with spacing ring flat-plate on the rotating shaft shaft part of each insulation sides seat both sides.
In the utility model, rotation axis one end to be measured is arranged in rotating shaft shaft part installing hole in coil rack, and keep rotation axis and rotating shaft to be total to central shaft, when rotation axis to be measured rotates, to rotate and the motion state such as axial endplay is passed to rotating shaft in coil rack, in rotating shaft, the eccentric iron core of installing, with rotating shaft rotation and axial endplay, changes the electromotive force of secondary coil output, can obtain rotation axis to be measured by the electromotive force of measuring secondary coil output and rotate and axial endplay information.
The utility model can be used for measuring rotation and the axial endplay information of rotation axis, and certainty of measurement is high, and has and measure preferably sensitivity.
Description of drawings
Fig. 1 is the utility model structural representation.
