The illustratively course of work of torque detecting apparatus of the present invention below：
Step S1：Press reset key, controller assigns instruction and allows the automatic running-in of detection device, and first sensor 12, second senses
Device 13a, 3rd sensor 13b and torque sensor receive command adapted thereto and carry out self-test, and motor 4 receives controller output
Driving signal rotation, drives lead screw 11 to rotate, so that the operation of nut 10 to the position P2 stops, waiting and instructing in next step.At this point, even
Extension bar 9 has run through measurement nut 8.
Step S2：Start travel button key, the driving signal that motor 4 receives controller output rotates clockwise, and drives silk
Thick stick 11 and nut 10 rotate clockwise, while nut 10 is mobile from right direction of the position P2 into Fig. 1, until moving to first
Stop at the position P1 where sensor 12.In motion process of the nut 10 from the position P2 to the position P1, since motor 4 is up time
Needle rotation, therefore 16 under tension of torque sensor acts on, and then the torque during the detection of torque sensor 16 position P2 to P1,
And will test result and be transmitted to controller, controller therefrom extracts a maximum of T 1max（That is maximum static lotus）Peaceful peak value T1d
（That is dynamic loading）.
Step S3：When nut 10 moves to the position P1, first sensor 12 detects nut 10, and will test signal biography
To controller, after controller receives the detection signal of first sensor 12, output drive signal makes 4 inverse time of motor to motor 4
Needle rotation, drives lead screw 11 and nut 10 to rotate counterclockwise, while nut 10 is mobile from left direction of the position P1 into Fig. 1,
Stop at the position P2 where second sensor 13a up to moving to.In motion process of the nut 10 from the position P1 to the position P2,
Since motor 4 is to rotate counterclockwise, the effect of being under pressure of torque sensor 16, and then torque sensor 16 detects P1 to P2
Torque during position, and will test result and be transmitted to controller, controller therefrom extracts a maximum of T 2max（It is i.e. maximum quiet
Load）Peaceful peak value T2d（That is dynamic loading）.
Step S4：When nut 10 moves at the position P2, second sensor 13a detects nut 10, and will test letter
Number it is transmitted to controller, after controller receives the detection signal of second sensor 13a, disconnects torque sensor 16, completed primary（One
A cycle T）It measures and records（Storage）.
If necessary to carry out the measurement of multiple cycle Ts, as long as controller circulation executes above-mentioned steps S2-S4.
It exits if necessary, presses conclusion button, after the measurement for completing a cycle T, i.e., nut 10 is in the position P2
When place, controller continues to output driving signal and makes motor 4 continue to rotate counterclockwise to motor 4, drives lead screw 11 and nut 10
It rotates counterclockwise, while nut 10 is mobile from left direction of the position P2 into Fig. 1, until moving to 3rd sensor 13b institute
The position P3 at stop, terminate measurement.At this point, connecting rod 9 has been detached from measurement nut 8.
Testing result such as Fig. 5（By taking the testing result of the position from P2 to P1 of nut 10 as an example）It is shown, finally to measurement result
It is averaged and obtains initial torque, by taking the detection of a cycle T as an example, initial torque maximum value（That is maximum static lotus）：
Tmax=（T1max+T2max）/2-T3；The flat peak value of initial torque（That is dynamic loading）：Td=（T1d+T2d）/2-T3.Wherein, T3 is
Bearing frictional torque, bearing frictional torque can drive empty run to measure in the case where dismantling lead screw 11 and nut 10 by motor 4.
