Abstract
The invention relates to a triple synchronous potentiometer which solves the problems that the manufacture difficulty is high and the process is complex due to three adjustable resistors coaxially arranged in the traditional triple potentiometer, and the three-phase nonlinear error is large and the precision is low when the traditional triple potentiometer is used. According to the triple synchronous potentiometer, three single potentiometers with the same resistance are arranged on one base plate, gears with the same tooth number are arranged on rotating shafts of three single potentiometers respectively and are used as driven gears, and teeth with the number being less than that of teeth of the driven gear by multiple times are formed on a driving rotating shaft, so that when the driving rotating shaft rotates one circle, the driven gear moves for a short distance, and no shaking phenomenon is ensured during adjustment; besides, the adjusting precision and the synchronism are ensured due to the same resistance of three potentiometers.
Description
Technical field
The present invention relates to electric utility, particularly relate to a kind of three synchronizing potential devices.
Background technology
At present in electric utility, adjust three potentiometers that three-phase voltage current uses, have another name called three adjustable resistors, what adopt is three adjustable potentiometers to be housed on coaxial, adjust while changing resistance, spin axis is adjusted in rotation, and rotary contact is installed respectively in spin axis, slides and change its resistance size in contact on ring resistance.This traditional potentiometer manufacture difficulty is large, and complex process is rotated spin axis shake greatly when use, produced the non-line error of three-phase large, is difficult to ensure three-phase synchronous and precision, the shortcomings such as manufacturing cost height.
Summary of the invention
The present invention is exactly in order to solve traditional three gang potentiometer manufacturing process complexity, cost is high, poor stability when use, the large defect of the non-line error of three-phase, invent a kind of three synchronizing potential devices, adopt the simply connected potentiometer of three similar resistance, utilize planetary mode, three synchronizing potential devices of composition, have thoroughly changed the defect of traditional three potentiometers.
For achieving the above object, a kind of three synchronizing potential devices of the present invention are installed three simply connected potentiometers that resistance is identical on a substrate, in the adjustment spin axis of three simply connected potentiometers, same gear are installed respectively.
The preferential technical scheme of the present invention is, be provided with substrate, the simply connected potentiometer of three equal resistances of installation of decile on the circumference of substrate, three same gears are installed respectively in the adjustment spin axis of simply connected potentiometer, initiatively spin axis is installed in the middle of three same gears, the initiatively gear engagement same with three of the gear in spin axis, forms planetary mechanical system.
The present invention further preferred technical scheme is, three potentiometers that gear has been installed belong to passive mechanical structure, and its active mechanical structure is the adjustment spin axis being provided with for tooth.
The present invention more further preferred technical scheme is that the number of teeth in the gear ratio active accommodation spin axis of installing on three simply connected potentiometers is many.
A kind of three synchronizing potential devices of the present invention, are in fact the simply connected potentiometers three similar resistance from function, install gear, then are provided with the active spin axis for tooth, are assembled on a substrate, form a complete synchronous planetary operating state.
Further aspect of the present invention, by the description of following embodiment, is clearly recorded.
Brief description of the drawings

Fig. 2 is simply connected potentiometer of the present invention and gear schematic diagram;
Fig. 3 is the active spin axis schematic diagram of the present invention for tooth.
Reference numeral explanation:
1, potentiometer gear; 2, potentiometer spin axis; 3, active spin axis; 4, driving gear; 5, substrate; 6, potentiometer.
Embodiment
As shown in drawings, three synchronizing potential devices are provided with substrate 5, three (A, B, C) potentiometers 6 of installation of decile on circumference on substrate 5, the gear 1 of the equal number of teeth is installed respectively in the spin axis 2 of three potentiometers 6, to in the active spin axis 3 for tooth, pack in the middle of the gear 1 of three potentiometers again, gear 4 on driving shaft 3 is engaged with the tooth on three potentiometers, form planetary mechanical system.
Three potentiometers 6 that gear 1 has been installed belong to passive mechanical structure, and its active mechanical structure is to adjust spin axis 3, in adjustment spin axis 3, is provided with gear.
The number of teeth than in active accommodation spin axis 3 of the gear 1 of installing on three simply connected potentiometers 6 is many.
In the present embodiment, the gear 1 of installing on three simply connected potentiometers 6 is the adjustment number of turns ratio according to the diameter of potentiometer 6 and active accommodation spin axis 3, decides its number of teeth separately.
Below the course of work of the present embodiment is illustrated:
In the course of work, adjust initiatively spin axis 3, make gear 4 in spin axis 3 initiatively engage rotation on the gear 1 of three simply connected potentiometers 6, because the number of teeth in active spin axis 3 is less than the multiple number of teeth of driven gear 1, so initiatively spin axis in adjustment, revolve turn around and driven gear just by the multiple very little segment distance of walking, so just there is not shake, the resistance of other three potentiometers is identical, just ensures three-phase synchronous.
