Abstract
The utility model relates to a low-cost rotary angle detector, which comprises a rotating shaft. The low-cost rotary angle detector is characterized in that a gearbox composed of multi-stage gears is connected to the rotating shaft; the gearbox composed of the multi-stage gears is connected with a resistance changing shaft of a precision potentiometer which is connected to a detection circuit. The variable speed ratio of the gearbox composed of the multi-stage gears is matched with a rotary angle of the rotating shaft and a rotary angle of the resistance changing shaft of the precision potentiometer. The utility model has the advantage that the made rotary angle detector has simple structure and low cost.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of rotation angle detecting device cheaply.
Background technology
Angle detection device commonly used at present is more to be to adopt photoelectric encoder, the circuit more complicated of its detection, and the cost of photoelectric encoder is also higher relatively, so utilize the structure more complicated of the Turn Angle Control System that photoelectric encoder makes, cost is too high, can't be applicable to that some simply, use on the product cheaply.
Summary of the invention
The purpose of this utility model is to solve the available technology adopting photoelectric encoder to carry out rotational angle and detect the too high problem of existing cost, and a kind of rotation angle detecting device cheaply is provided.A kind of rotation angle detecting device cheaply of the utility model design, comprise rotating shaft, it is characterized in that: be connected with the wheel box that multi-stage gear is formed in rotating shaft, the wheel box that multi-stage gear is formed connects the change resistance axle of a precision resistor, and precision resistor inserts testing circuit.The angle of rotation of the angle of rotation of the gear ratio coupling rotating shaft of the wheel box that multi-stage gear is formed and the change resistance axle of precision resistor.The utility model has the advantages that and make that the rotation angle detecting device of making is simple in structure, with low cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Comprise rotating shaft 1 among the figure, it is characterized in that: be connected with the wheel box 2 that multi-stage gear is formed in rotating shaft 1, the wheel box 2 that multi-stage gear is formed connects the change resistance axle 5 of a precision resistor 3, and precision resistor 3 inserts testing circuit 4.The angle of rotation of the angle of rotation of the gear ratio coupling rotating shaft 1 of the wheel box 2 that multi-stage gear is formed and the change resistance axle 5 of precision resistor 3.When in common low-value product, using the utility model, be connected with the wheel box 2 that multi-stage gear is formed in the rotating shaft 1 of its rotational angle that needs can be detected, can be according to concrete actual conditions, comprise that precision resistor 3 becomes the complete rotation angle of resistance axle 5 and rotating shaft 1, set the gear ratio of the wheel box 2 of the multi-stage gear composition that is fit to, be converted into the complete rotation angle that precision resistor 3 becomes resistance axle 5 as complete rotation angle with rotating shaft 1, thereby the rotational angle of rotating shaft 1 is directly changed into the variation of the resistance of precision resistor 3, thereby obtain an electric signal, as this electric signal Access Control circuit 4 just being finished the acquisition of the rotational angle of rotating shaft 1, if control circuit 4 connects the rotation that a driving circuit 6 removes to control the motor 7 that drives rotating shaft 1 again, then finish the control of a closed loop.
Claims (2)
1, a kind of rotation angle detecting device cheaply comprises rotating shaft, it is characterized in that: be connected with the wheel box that multi-stage gear is formed in rotating shaft, the wheel box that multi-stage gear is formed connects the change resistance axle of a precision resistor, and precision resistor inserts testing circuit.
2, by the described a kind of rotation angle detecting device cheaply of claim 1, it is characterized in that: the angle of rotation of the angle of rotation of the gear ratio coupling rotating shaft of the wheel box that multi-stage gear is formed and the change resistance axle of precision resistor.
