Abstract
The utility model relates to a torque sensor, in particular to a strain type torque sensor. The strain type torque sensor comprises a base, a jacket is fixed above the base, end covers are fixed in the front and rear of the jacket, a shaft penetrates through centers of the end covers, a strain gauge sticking patch is arranged on the shaft, and a support disc is arranged on the outer side of a shaft portion in the jacket. Compared with torque sensors in prior art, the strain type torque sensor has the advantages that the design is reasonable, the structure is simple, the size is small, and the measuring accuracy is high.
Description
Technical field
The utility model relates to a kind of torque sensor, particularly a kind of strain-type torque sensor.
Background technology
The torque sensor range of application is very extensive, almost be applied to the detection of all devices output torque and power, existing domestic a large amount of employing phase differential torque sensors or sliding ring type torque sensor, the phase differential torque sensor is inconvenient under low speed is measured, sensor bulky and heavy, sliding ring type torque sensor operating rate is low and can not long time continuous working.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of strain-type torque sensor, it adopts contactless transfer mode, uses the principle of work of wireless power and wireless output, has solved alternate manner and has measured the drawback that dynamic torque exists.
The technical scheme that the utility model adopts is as follows:
A kind of strain-type torque sensor comprises base, and described base top is fixed with overcoat, and described overcoat front and back are fixed with end cap, and the end cap center is interspersed with axle, is provided with the foil gauge paster on the described axle, and the shaft portion arranged outside of described overcoat inside has supporting disk.
Be provided with bearing between end cap and the axle.
Be fixed with large gland on the end cap inwall.
Strain-type torque sensor of the present utility model, axle two with keyway is two input/output terminals of sensor, the strain section is pasted in the square district in the middle of the axle, the foil gauge paster is set, axle is contained in the overcoat by bearing, two is fixed by end cap, signal processing part is divided on the base, by the wireless power mode power supply is offered strain bridge, the signal of strain bridge outputing to Displaying Meter by the wireless receiver of signal processing with signal amplification and pressure/frequently conversion, the stationary plane of base or sensor and equipment keeps the stable of sensor.The supporting disk part links to each other with turning axle, has the function of measuring rotating speed.
Strain-type torque sensor of the present utility model, it adopts electric measurement technique of strain gage, forms strain bridge at elastic shaft, provides power supply can record the electric signal that this elastic shaft is turned round to strain bridge.After this strain signal amplification, through the voltage-frequency conversion, be transformed into the frequency signal that is directly proportional with moment of torsion.
Strain-type torque sensor of the present utility model, it compared with prior art has characteristics reasonable in design, simple in structure, that volume is little, measuring accuracy is high.
Description of drawings
Fig. 1 is the structural front view of strain-type torque sensor of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to the structure cut-open view.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Shown in accompanying drawing 1,2, a kind of strain-type torque sensor, comprise base 1, described base 1 top is fixed with overcoat 2, described overcoat 2 front and back are fixed with end cap 3, end cap 3 centers are interspersed with axle 4, are provided with foil gauge paster 5 on the described axle 4, and the axle 4 part arranged outside of described overcoat 2 inside have supporting disk 6.
Be provided with bearing 7 between end cap 3 and the axle 4.
Be fixed with large gland 8 on end cap 3 inwalls.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
