Abstract
A micro-range dynamic torque sensor is formed by an input shaft, an output shaft, a torsion spring, an input photoelectric coding disc, an output photoelectric coding disc, an engine base and the like; one end of the input shaft is connected with the torsion spring while other end is connected with the output shaft; the photoelectric coding discs are respectively arranged on the input shaft and the output shaft; the integral input shaft and the integral output shaft are respectively arranged on front and rear end covers by a bearing; the front and rear end covers are fixedly arranged at two sides of the engine base; each of the front and rear end covers is provided with a photoelectric reading hole capable of reading the phase signal of a shaft. During measurement, the torque is sent to the torsion spring by the input shaft, the torsion spring sends the torque to the output shaft by the energy storing action of the torsion spring, and as the energy storing action of the torsion spring increases the phase difference of the input shaft and the output shaft, the limitation on the lowest range in the measuring is greatly reduced, the phase difference signal is convenient to read, and the precision for measuring the minimal range torques is improved.
Description
Technical field
The utility model relates to experimental measurement technical field, is specially a kind of dynamic torque field of measuring technique, particularly small range dynamic torque sensor.
Background technology
Moment of torsion is one of important indicator of driving member, is also the important content that mechanical output is measured.Because its measurement of singularity of moment of torsion is a technical barrier always.At present mostly the measurement of moment of torsion is to adopt the mode that sensing unit is directly set on transmission shaft, pulls foil gauge to realize the measurement to moment of torsion by the torsional deformation of transmission shaft.This mode actual measurement be the rigid deformation of transmission shaft, the rigidity that is all made of a steel itself due to transmission shaft is better, deflection in the time of transmitting torque is very little, this brings difficulty just to the small moment of torsion of measurement, simultaneously this measurement need to be on spindle unit its installation requirement of installing device very high, and can affect the normal work of spindle unit.So the torque sensor sensitivity that prior art is manufactured is low, and signal output inconvenience, the normal measurement of Shaft Torque affected.
Summary of the invention
From foregoing prior art, task of the present utility model is to provide a kind of device and structure for measure the dynamic torque of small range with simple methods.Technical problem to be solved in the utility model is to replace stiff shaft by a simple device, the phase angle difference that increases as much as possible transmission shaft input end and output terminal in transmitting torque has reduced the accuracy requirement of reading, is convenient to be inputted with the phase angle of two ends of output shaft and realized the dynamic torque of small range is measured by measurement.
The technical scheme that technical problem to be solved in the utility model adopts is: sensor is made up of input shaft, output shaft, torsion spring, two photoelectric coded disks of input and output, support etc., it is characterized in that input shaft one end connects the other end connection output shaft of torsion spring, torsion spring, a photoelectric coded disk of each installation above input and output shaft, input and output shaft entirety is arranged on respectively on former and later two end caps by bearing separately, former and later two end caps are fixedly mounted on support both sides, respectively have a photoelectric reading hole on front and rear cover.
Advantage of the present utility model and obtainable usefulness have: be divided into input and two of outputs for the transmission shaft of measuring, centre connects by torsion spring, and tested moment of torsion passes to input shaft, then passes to output shaft by torsion spring, finally passes to load; The phase differential that has pulled open input shaft and output shaft due to the elastic stored energy effect of torsion spring makes small moment of torsion also can between input and output shaft, cause larger phase differential, has realized the measurement of small range.
Accompanying drawing explanation
Accompanying drawing uses structural drawing of the present utility model, wherein: 1. input shaft, 2. bearing, 3. front end end cover, 4. input photoelectric reading hole, 5. front end end cover, 6. support, 7. input photoelectric coded disk, 8. torsion spring, 9. output photoelectric code-wheel, 10. rear end cap, 11. output photoelectric reading holes, 12. output shafts.
Embodiment
Consult on accompanying drawing input shaft 1 and be provided with and input photoelectric coded disk 7, input shaft 1 rear end is connected with torsion spring 8, whole input axis body is arranged on bearing 2, be arranged on above front end end cover 3 by bearing integral again, front end end cover 3 is arranged on support 6 fixing, and the other end of torsion spring 8 is connected with output shaft 12, and output photoelectric code-wheel 9 is installed on output shaft, integral installation the same as input shaft is on rear end cap 11 and be arranged on above support 6 fixingly, has reading hole 4 and 11 on former and later two end caps.
The front end of input shaft 1 is delivered in measured torque by shaft coupling, input shaft by moment of torsion deliver to torsion spring 8, torsion spring 8 by self distortion action by being delivered to after input torque phase delay on output shaft 12, be finally sent to load below by output shaft.Because two photoelectric coded disks of input and output are connected with input and output shaft respectively, so the photosignal on photoelectric coded disk represents respectively input and the phase signal of exporting two axle heads, the input of the read head of photoelectric reading equipment by former and later two end caps and output photoelectric reading hole are read photoelectricity phase signal and just can be calculated the phase differential of input and output signal, thereby measure moment of torsion.
Because photoelectric reading equipment is not at the protection domain of this patent, therefore its principle of work and process are no longer narrated.
