Description
Technical field
The utility model relates to a kind of sensor, particularly relates to a kind of torque rotary speed sensor.
Background technology
Any plant equipment all needed the test carrying out mechanical transmission performance before enabling, if do not come into operation through the plant equipment of measuring mechanical property, caused reduction power transmission efficiency, also can cause the generation of mechanical fault.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of torque rotary speed sensor.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical matters adopts: this torque rotary speed sensor comprises stand-by motor, belt, support, sleeve, annular wheel, magnet steel, outer rotor, coil, end cap, torsion shaft and bearing, support upper end is provided with sleeve, the upper end of sleeve is provided with stand-by motor, stand-by motor connects belt, torsion shaft, annular wheel, magnet steel, outer rotor, bearing and coil is provided with in sleeve, annular wheel, magnet steel are fixed on end cap, and outer rotor is fixed in torsion shaft.
The beneficial effects of the utility model are: the structure of this torque rotary speed sensor is simple, can realize mechanical quantity and change into amount of electrons.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, stand-by motor, 2, belt, 3, support, 4, sleeve, 5, annular wheel, 6, magnet steel, 7, outer rotor, 8, coil, 9, end cap, 10, torsion shaft, 11, bearing.
Embodiment
Fig. 1 is structural representation of the present utility model, figure comprises stand-by motor 1, belt 2, support 3, sleeve 4, annular wheel 5, magnet steel 6, outer rotor 7, coil 8, end cap 9, torsion shaft 10 and bearing 11, support 3 upper end is provided with sleeve 4, the upper end of sleeve 4 is provided with stand-by motor 1, stand-by motor 1 connects belt 2, torsion shaft 10, annular wheel 5, magnet steel 6, outer rotor 7, bearing 11 and coil 8 is provided with in sleeve 4, annular wheel 5, magnet steel 6 are fixed on end cap 9, and outer rotor 7 is fixed in torsion shaft 10.
When annular wheel 5 and outer rotor 7 relatively rotate, because magnetic flux constantly changes, just induces in coil the induced potential of near sinusoidal ripple, the initial phase difference of two induced potentials is constant, consider positive back-loading, design is on about 180 ° of positions, when adding torsion, torsion shaft twists distortion.Within the scope of elastic force, external torque is directly proportional to mechanical twisting angle.When the moment of torsion of sensor is increased to ratings, thus realize the process that mechanical quantity changes into amount of electrons.
