6. turning axle phase differential calibration system according to claim 4, be characterised in that: the demarcating steps or the calibration process of this calibration system are: demarcate under turning axle rotates: 1.. when this calibration system carries out the phase differential timing signal to instrument or the device of measuring the turning axle phase differential, at first install the instrument of measurement turning axle phase differential or the sleeve A of device, sleeve B just has a phase differential between the two, thereby this phase differential provides a high-precision phase signal promptly to demarcate phase difference value to rack-mount, on the sleeve A, the instrument or the device of the measurement turning axle phase differential of being demarcated part on the sleeve B; 2.. turn motor knob, will show on the motor display panel that is set a tachometer value, starter motor is by setting the tachometer value rotation, note the turning axle upper bush A of this settings tachometer value and the phase difference measurement value between sleeve B give rack-mount, sleeve A goes up, instrument or the device of being demarcated measurement turning axle phase differential partly on the sleeve B; 3.. by 1.., 2.. step or process make rack-mount, sleeve A goes up, the instrument of the measurement turning axle phase differential of being demarcated part on the sleeve B or the phase data that device will obtain one group of high-precision demarcation and measurement; 4.. the rotation dividing head, the urceolus rotation of control sleeve B, the urceolus that makes sleeve B with the relative turn of inner core a phasing degree, making has a new phase differential again between sleeve A, sleeve B, thus this phase differential provide another high-precision phase signal promptly demarcate phase difference value to rack-mount, sleeve A go up, the instrument or the device of the measurement turning axle phase differential of being demarcated part on the sleeve B; 5.. 4.. repeat 4. under step or the process., 2.., 3.. step or process, make instrument or the device of measuring the turning axle phase differential obtain the many groups of phase datas of demarcating and measuring, need handle the many groups of phase datas of demarcating and measuring by demarcating regulation, thereby instrument or the device of measuring the turning axle phase differential are demarcated.
