Abstract
The utility model provides a novel connecting device of a potentiometer. The novel connecting device of the potentiometer comprises a motor with a motor shaft and a potentiometer with a potentiometer shaft, and is characterized in that the motor and the potentiometer are fixedly connected together, a motor shaft gear is fixedly arranged on the motor shaft, a potentiometer shaft gear is fixedly arranged on the potentiometer shaft, and the motor shaft gear and the potentiometer shaft gear are engaged with each other. A mounting support is fixedly arranged on the potentiometer, a plurality of elongated mounting holes are arranged on the mounting support, and mounting screws are screwed in mounting screw holes arranged on the motor after passing through the elongated mounting holes to enable the motor and the potentiometer to be fixedly connected together. The novel connecting device of the potentiometer can use standardized potentiometers with the same number of coils, and adjusts gear radio of two gears by replacing the motor shaft gear and the potentiometer shaft gear, thereby enabling the motor shaft to produce different kinds of numbers of the coils, being beneficial for using of standardized potentiometers, reducing kinds of special potentiometers, and reducing making cost.
Description
Technical field
The utility model belongs to a kind of motor accessory, relates in particular to a kind of device that motor shaft is connected with potentiometer.
Background technique
Potentiometer is to have three Outlets; Resistance can be by the resistive element of certain Changing Pattern adjusting; Potentiometer usually by resistance body and movably brush form, when brush when resistance body moves, promptly obtain to become the resistance value or the voltage of certain relation with displacement amount at output terminal.Can be divided into individual pen and multiturn potentiometer according to the number of turns.Usually, the potentiometer shaft 2 of potentiometer 200 directly links (like Fig. 1) through coupling 300 with the motor shaft 1 of motor 100. and motor shaft revolves and turns around, and potentiometer shaft just turns around.Change the rotational position situation of grasp motor shaft that just can be indirect through the signal on the potentiometer.
Because the number of turns of potentiometer receives the restriction of structure.The generally held standard article are all made the specific number of turns.If adopt the conventional Placement of existing technology, because the potentiometer number of turns is limited, motor shaft rotating cycle to the left or to the right will receive very big restriction.And if the rotating cycle of increase motor shaft will carry out specific customization to potentiometer, so at first manufacture cost is than higher, and its Minor Cycles is many, and it is bigger that the volume of potentiometer is just done, and installs and uses for use and will receive very big influence.
The model utility content
The utility model provides a kind of novel connection set of potentiometer, its objective is to solve the shortcoming that existing technology exists, and reduces the use and the potentiometer size of special potentiometer, reduces manufacture cost.
The utility model solves the technological scheme that its technical problem adopted:
A kind of novel connection set of potentiometer; Comprise motor with motor shaft and potentiometer with potentiometer shaft; It is characterized in that: motor and potentiometer are fixed together; Be installed with generator shaft gear on the motor shaft, be installed with the potentiometer shaft gear on the potentiometer shaft, generator shaft gear and potentiometer shaft gear are meshing with each other.
Potentiometer is installed on the mounting bracket, and mounting bracket is provided with several long strip mounting holes, and mounting screw passes and is arranged in behind the long strip mounting hole in the installation screw set on the motor and motor and potentiometer are fixed together.
The usefulness of technique scheme is:
The motor shaft of the utility model does not directly connect with potentiometer shaft, but through indirect the linking together of the gear of two different numbers of teeth.The gear mesh of the different numbers of teeth just can produce different velocity ratios.Thereby the number of turns that makes the rotatable number of turns of motor shaft equal potentiometer multiply by gear ratio.So adopt the standardization potentiometer of the number of turns of the same race, regulate the gear ratio of two gears through changing generator shaft gear and potentiometer shaft gear, just can make motor shaft produce different types of number of turns.Therefore help the use of standardization potentiometer, reduced the kind of special potentiometer and the size of potentiometer, reduced manufacture cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the existing technology structural representation;
Fig. 2 is the utility model schematic appearance;
Fig. 3 is the utility model three-dimensional exploded view.
Embodiment
The structure of the utility model such as Fig. 2, shown in Figure 3,
External part at the motor shaft 1 of motor 100 has an installation panel 3, is connected it and motor 100 with 4 mounting screws 31.Be designed groove 30 parts on the installation panel 3, be used for ccontaining two gears of laying: generator shaft gear 10 and potentiometer shaft gear 20.One end of groove 30 corresponding motor shafts 1 has through hole 31, and motor shaft 1 just can be stretched from this through hole 31 like this.Generator shaft gear 10 just is installed on the motor shaft 1, is 90 jiaos with two fastening screw trip bolts 11 and is fixed on generator shaft gear 10 on the motor shaft 1.Mounting bracket 4 has four long strip slotted holes 40, passes through 4 mounting screws 41 in the screw 32 that is arranged in again behind the grooved hole 40 on the installation panel 3 and links to each other mounting bracket 4 with installation panel 3.Potentiometer 200 is installed on the mounting bracket 4 through locking nut 5.Like this, potentiometer 200 forms with motor 100 and is connected.Potentiometer shaft gear 20 is installed on the potentiometer shaft 2, also is 90 jiaos with two fastening screw trip bolts 21 and is fixed on potentiometer shaft gear 20 on the potentiometer shaft 2.Generator shaft gear 10 is meshing with each other with potentiometer shaft gear 20.Like this; The rotational drive motor shaftgear 10 of motor shaft 1; Generator shaft gear 10 drive potential device shaftgears 20, potentiometer shaft gear 20 drive potential device axles 2, thus motor shaft 1 is with the gear ratio driven potentiometer shaft 2 of generator shaft gear 10 with potentiometer shaft gear 20.
The gap can be through unclamping mounting screw 41 between generator shaft gear 10 and the potentiometer shaft gear 20, again because grooved hole 40 structures and can displacement mounting bracket 4 lock the mode of mounting screw 41 again and finely tune.When the size of generator shaft gear 10 and potentiometer shaft gear 20 changes and when needing to change the wheelbase of motor shaft 1 and potentiometer shaft 2, also can pass through said method adjusting axle distance.
