Abstract
The utility model discloses a torque detection assembly for an electric executer, comprising measuring shafts for outputting the deformation amounts of force output shafts, wherein the rotating angles of the measuring shafts are corresponding to the deformation amounts of the force output shafts one by one. The torque detection assembly for an electric executer is characterized in that: measuring pinions are connected to the measuring shafts, an encoder is disposed aside the measuring pinions, and the measuring pinions are mutually engaged with the pinions of the encoder. The torque detection assembly for an electric executer disclosed by the utility model can accurately measure the output torsional torque of the electric executer, as well as is stable and reliable in use, and low in cost.
Description
Technical field
The utility model relates to a kind of YE that is used for valve control, what be specifically related to is a kind of moment detection components of YE.
Background technology
YE is mainly used in the automatic control of valve, can be on the spot or long-range valve is controlled automatically through it, use very extensively in oil, chemical industry and other field.An output torque that key parameter is exactly a force-output shaft of YE; Present YE; The structure of its moment detection components is such: it comprises a measurement axis that the force-output shaft deflection is exported, and the rotational angle of measurement axis is corresponding one by one with the deflection of force-output shaft, and the force-output shaft deflection has corresponding relation with force-output shaft moment again; The rotating band moving cam of measurement axis; The keying of the displacement control moment microswitch through cam, but this kind structure is regulated trouble, precision is low, cannot show the moment state; A kind of in addition structure is: adopt pressure-sensitive electronic devices and components; Pressure through detecting on the pressure-sensitive electronic devices and components changes the output torque state that demonstrates mechanical axis; Thereby force-output shaft moment is set, be very easy to damage but the shortcoming of this kind structure is pressure-sensitive electronic devices and components, peripheral circuit is complicated; Cost is high, and temperature influence is bigger.
Summary of the invention
In view of the problem that present known technology exists, the technical matters that the utility model will solve is to be to provide that a kind of measurements is accurately high, use is reliable and stable, the moment detection components of the YE that cost is low.
For solving the problems of the technologies described above, the utility model takes following technical scheme to accomplish:
The moment detection components of YE; Comprise the measurement axis that the force-output shaft deflection is exported; The rotational angle of measurement axis is corresponding one by one with the deflection of force-output shaft; It is characterized in that: be connected with the measurement pinion wheel on the said measurement axis, the next door of measuring pinion wheel is provided with scrambler, and the pinion wheel of measuring pinion wheel and scrambler is meshing with each other.
The beneficial effect of the utility model is: with encoder applies to the rotational angle that detects measurement axis; Because the rotational angle of measurement axis and force-output shaft moment have relation one to one; So just can accurately demonstrate the output torque state of mechanical axis in real time through the output of scrambler, moreover scrambler uses reliable and stable; Cost is low, receives extraneous thermal effect little.So the moment detection components of the utility model has the accurate height of measurement, use is reliable and stable, the advantage that cost is low.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the D-D view of Fig. 1 amplifies.
Embodiment
Accompanying drawing has been represented the technical scheme and the embodiment of the utility model, combines accompanying drawing to further describe each relevant details of embodiment below again.
With reference to accompanying drawing 1,2, the moment detection components of this kind YE comprises the measurement axis 1 that the force-output shaft deflection is exported; The rotational angle of measurement axis 1 is corresponding one by one with the deflection of force-output shaft, and force-output shaft deflection and force-output shaft moment have corresponding relation, is connected with on the said measurement axis 1 to measure pinion wheel 2; The next door of measuring pinion wheel 2 is provided with scrambler 4, and the pinion wheel 3 of measuring pinion wheel 2 and scrambler is meshing with each other, and the base plate 5 that scrambler is installed is rotatably connected on the ramuscule post 8 that fixedly installs through screw 6; One end of torsion spring 7 is located on the ramuscule post 8, and the other end is located on the said base plate 5, like this; Under the effect of torsion spring 7; The pinion wheel 3 of scrambler closely reclines with measuring pinion wheel 2, effectively eliminates the back lash, improves accuracy of detection.
