As shown in Figure 10, the calibration steps of a kind of machinery being applied to torque sensor calibration, step is as follows:
1. force transmitting board 1, sensor to be calibrated 2, contiguous block 3, standard transducer 4 being connected in series by screw, be connected by screw with the calibration clamp main shaft 13 assembled, inserted in U-shaped support 19 force transmitting board 1 one end, U-shaped support 19 is fixed on a position；
2. test starts, crank handle 6, and worm screw 10 drives main shaft 13 to rotate, force transmitting board 1 synchronous axial system, because force transmitting board 1 is fixed by U-shaped support 19, force transmitting board 1 is provided the active force of an opposition, this opposition and worm screw 10 to produce moment of torsion one by one on main shaft 13 by U-shaped support；
3. because force transmitting board 1, sensor to be calibrated 2, contiguous block 3, standard transducer 4 are cascaded, sensor 2 to be calibrated is identical with standard transducer 4 reading theory, worm screw 10 has latching characteristics, often rotate an angle, record one group of data torque by treating that school sensor digital display meter 2-1, standard transducer digital display meter 4-1 read, comparative reading, finally draws correlation curve figure, it is judged that whether sensor 2 to be calibrated meets instructions for use.
Two sensors of series connection on main shaft 13, a higher standard transducer 4 for 0.01N/M of accuracy class, another precision precision is the sensor to be calibrated 2 of 0.1N/M.
This machinery theoretical foundation is that the moment of torsion on same axle is identical, and the sensor reading of series connection is theoretically identical.The cardinal principle of this calibrating installation is by turbine and worm mechanism, and the rotation in horizontal direction is converted to the upper rotation of vertical direction.Turbine and worm mechanism has the function of self-locking simultaneously, and after handwheel transmission, main shaft will not turn round, it is possible to more accurate reading, contrast.The calibration range of this machinery is 0～200N/M, is 1:3 because selecting the gear ratio of turbine and worm, so just can reach the needs calibrated with less power, this is also one of the advantage of this calibrating installation.
