Abstract
The utility model belongs to the electro-dynamic actuator field, which particularly belongs to the regulating valve positioning mechanism field. A continuous adjusting positioning device of an electro-dynamic actuator is characterized in that the utility model comprises an upper positioning gear wheel and a lower positioning gear wheel, a spring 4 is arranged between the two gear wheels, both ends of the spring respectively contact with an upper positioning gear wheel 6 and a lower positioning gear wheel 5 to form a corresponding forced relationship, and the upper positioning gear wheel and the lower positioning gear wheel are simultaneously geared with an output wheel 1. The utility model has the advantages that because the utility model adopts a structure that the spring is added between the upper positioning gear wheel and the lower positioning gear wheel, the existing of the mating gaps of the original gear wheels is overcome, and position control is more accurate.
Description
Technical field
The utility model belongs to the electric actuator field, specifically belongs to modulating valve positioning means field.
Background technique
Common adjustment type electric valve positioning means is as shown in Figure 1: the outgoing position angle of final controlling element characterizes by the rotation angle of output wheel, output wheel 1 and Positioning Gear 2 engagements, driving Positioning Gear 2 rotates, Positioning Gear 2 is connected with potentiometer 3, and then potentiometer also rotates thereupon, and the different resistance signal of potentiometer output has just characterized the rotation angle of output shaft (being final controlling element), by resistance signal, we just can control final controlling element makes output wheel turn to the angle of requirement.
But because there is the gap in the engagement of gear 1 and gear 2, when forward or reverse, because the existence in gap, identical resistance signal will be different at its output shaft rotation angle, and then bring error for the accuracy of control like this.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of electric actuator to regulate positioning device continuously, solves because the existence of gear backlash brings the problem of error for the accuracy of control.
The purpose of this utility model is achieved in that a kind of electric actuator regulates positioning device continuously, it is characterized in that: comprise two Positioning Gears up and down, in the middle of two Positioning Gears, be provided with spring 4, the two ends of spring contact with following Positioning Gear 5 with last Positioning Gear 6 respectively, form corresponding stressed relation, Positioning Gear meshes with output wheel 1 simultaneously up and down.
Working principle:
Positioning Gear forms corresponding stressed relation under the effect of middle springs up and down, has clamped output wheel at the position of engaging gear, has overcome the existence in gap.
Compared with prior art, the beneficial effects of the utility model are: owing to adopted the middle structure that adds spring of Positioning Gear up and down, overcome the existence of original gear backlash, made positioning control more accurate.
Description of drawings
Fig. 1 is traditional position structure schematic representation, wherein, and 1 output wheel, 2 Positioning Gears, 3 potentiometers.
Fig. 2 is the utility model structural representation, wherein, and 1 output wheel, 3 potentiometers, 4 springs, 5 times Positioning Gears, Positioning Gear on 6.
Fig. 3 is a kind of embodiment structural representation of the utility model, wherein, and 4 springs, 5 times Positioning Gears, Positioning Gear on 6,9 spring stationary axle, 10 spring action axle A, 11 spring action axle B.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 2, a kind of electric actuator is regulated positioning device continuously, comprise two Positioning Gears up and down, in the middle of two Positioning Gears, be provided with spring 4, the two ends of spring contact with following Positioning Gear 5 with last Positioning Gear 6 respectively, form corresponding stressed relation, Positioning Gear meshes with output wheel 1 simultaneously up and down.Positioning Gear 2 is connected with potentiometer 3, and then potentiometer also rotates thereupon, and the different resistance signal of potentiometer output has just characterized the rotation angle of output shaft (being final controlling element), by resistance signal, we just can control final controlling element makes output wheel turn to the angle of requirement.
As shown in Figure 3, detailed structure view for Positioning Gear: following Positioning Gear 5 is provided with spring stationary axle 9, U type spring 4 is fixed on it, spring one end touches to dial goes up the spring action axle B11 that sets on the Positioning Gear 6, the trend that Positioning Gear is had rotate counterclockwise, the other end of spring is dialled down the spring action axle A10 that sets on the Positioning Gear 5, makes down the oriented trend that clockwise rotates of positioning disk gear; Following Positioning Gear and last Positioning Gear can rotate around jack shaft.Opposite rotation trend has overcome the existence of back lash when making Positioning Gear output wheel engagement up and down, guaranteed accuracy, the uniqueness of control angle.
