The utility model provides a potentiometer based stepless regulator which comprises a knob type potentiometer and a casing. A big gear and a small gear which are mutually meshed are installed inside the casing, a knob is installed on a rotating shaft of the big gear, the small gear is connected with a regulating rod of the potentiometer, the knob is rotated to rotate the adjusting rod of the potentiometer by that the big gear drives the small gear, and then small angle rotation of the knob is embodied as large angel rotation on the potentiometer, thereby increasing the adjusting accuracy of the potentiometer at specific gears.
Description
Technical field
The utility model relates to a kind of stepless regulator, more particularly, relates to a kind of stepless regulator based on potentiometer.
Background technology
Thereby potentiometer is to obtain a magnitude of voltage at the two ends of divider resistance by the size of regulating its divider resistance, because the divider resistance of potentiometer is to change continuously within the specific limits, the voltage at its divider resistance two ends also is to change continuously within the specific limits, this voltage of continually varying within the specific limits can be used as the signal input of step-less adjustment, so potentiometer is used as the trim in the stepless regulator widely.
The knob potentiometer changes the different magnitude of voltage that the divider resistance value produces by rotating its adjusting rod, the revolvable angular range of adjusting rod institute is near 360 degree, regulate for convenience, the dial of a collar plate shape is set toward contact around adjusting rod, indicates residing gear when adjusting rod rotates to this position on it.But some product is for the needs of outward appearance or other reasons, its dial only is distributed in the circular arc of semicircle or 1/3rd circles, or even littler circular arc in, the gear scale of this little radian makes adjusting rod also only rotate having within the scope of scale, so the true adjustable range of potentiometer divider resistance be its maximal regulated scope half or 1/3rd even littler, in so less adjustable range, divide the gear of similar number, can make adjacent two grades of pairing resistance values more approaching, the voltage of divider resistance two ends output is also more approaching, be easy to generate bigger error when transferring the files, cause degree of regulation poor.
The utility model content
The technical problems to be solved in the utility model is, when only being distributed in the scope of a bit of circular arc at the gear scale of existing potentiometer, the adjustable range of the divider resistance of potentiometer is its maximal regulated scope sub-fraction, thereby make adjacent two grades of pairing magnitudes of voltage more approaching, be easy to generate bigger error during adjusting, the problem of degree of regulation difference, and provide a kind of stepless regulator based on potentiometer, this kind adjusting device also is to carry out stepping in the divider resistance maximal regulated scope of potentiometer in the gear scale only is distributed in a bit of circular arc scope the time, widen the difference of adjacent two grades of pairing potential values, thereby improve degree of regulation.
The technical scheme that its technical problem that solves the utility model adopts is: propose a kind of stepless regulator based on potentiometer, comprise the knob potentiometer, also comprise a housing, a pair of intermeshing gear wheel and pinion are installed in the described housing, installing one knob in the rotating shaft of described gear wheel, described pinion is connected with the adjusting rod of potentiometer.
In the stepless regulator based on potentiometer described in the utility model, the axis part of described pinion one side is provided with an axis hole, and the end of the adjusting rod of described potentiometer is complementary with described axis hole and sleeve forms not rotatable being connected with pinion in axis hole.
In the stepless regulator based on potentiometer described in the utility model, described axis hole is a semicircle orifice.
In the stepless regulator based on potentiometer described in the utility model, described axis hole is a hexagonal hole.
In the stepless regulator based on potentiometer described in the utility model, the rotating shaft of described gear wheel and knob are split-type structural, described knob is provided with semicircle or hexagonal axis hole, and match with described axis hole in the termination of the rotating shaft of described gear wheel and sleeve forms a fixed connection with knob in described axis hole.
In the stepless regulator based on potentiometer described in the utility model, the rotating shaft and the knob of described gear wheel are structure as a whole.
The stepless regulator based on potentiometer in the utility model is compared with existing potentiometer adjusting device, has following advantage:
1, when the gear scale only is distributed on a bit of circular arc, the pairing resistance value distribution of gear on the scale is in the adjustable maximum magnitude of the divider resistance of potentiometer, remain in the adjustable maximum magnitude of potentiometer divider resistance and carry out stepping, make the difference of the resistance value of adjacent two grades of pairing divider resistances reach maximum, guarantee the adjusting high accuracy of potentiometer.
2, adopt gear drive, relative slip can not take place, can make precision keep stable.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is based on the structural representation of the stepless regulator of potentiometer in the utility model.
Embodiment
Fig. 1 shows a kind of more excellent execution mode of the present utility model.
See also shown in Figure 1, the stepless regulator based on potentiometer in the utility model comprises a knob potentiometer 1, housing 3, knob 5, a pair of gear wheel that is meshed 6 and pinion 4 are installed in the housing 3, gear wheel 6 is 4 with the gearratio of pinion 4, knob 5 is rotating shaft 7 integrative-structures with gear wheel, in the specific implementation, the rotating shaft of gear wheel and knob also can be made split-type structural, be provided with semicircle on knob or hexagonal axis hole this moment, the termination of the rotating shaft of gear wheel match with axis hole and sleeve in axis hole with the realization rotating shaft of gear wheel and fixedlying connected of knob.The axis part of pinion 4 one sides is provided with the axis hole 8 of a semicircle, and the end and the semicircular axis hole 8 of the adjusting rod 2 of potentiometer are complementary, and adjusting rod 2 sleeves form not rotatable being connected with pinion in this axis hole 8.
Its knob of traditional potentiometer is to be directly installed on the adjusting rod, for the gear scale on the circular arc that is distributed in quadrant, be adjusted to when the most high-grade from shelves of the end, about adjusting rod only revolves and turn 90 degrees, the adjustable range of its divider resistance is 1/4th of a maximal regulated scope, and the adjusting device in the present embodiment, when knob 5 rotations 1 are spent, drive pinion 4 by gear wheel 6, make adjusting rod rotation 4 degree of potentiometer, when the deep low gear of knob from the gear scale rotates to when the most high-grade, adjusting rod 2 has rotated 360 degree nearly, if the gear that is divided is identical, then in the present embodiment, the difference of two pairing divider resistances between adjacent two grades is 4 times of traditional potentiometer adjusting device, and correspondingly the degree of regulation of the adjusting device in the present embodiment on concrete gear also is 4 times of traditional potentiometer adjusting device.
Gear wheel in the present embodiment and the gearratio between the pinion are 4, in the specific implementation, can determine according to the pairing radian of gear scale, for example, when the gear scale was distributed on the semi arch, the gearratio of gear wheel and pinion then was 2, when being distributed on 1/3rd circular arcs of justifying as if the gear scale, the gearratio of gear wheel and pinion then is 3, by that analogy.
