国外 齿形齿向的测量方法

有哪位高手知道呀？谢谢

1.    PURPOSE : TJIS DWG PROVIDE FOR RULESABOUT GRADE OF COMPLETE CURVE AND LEAD FOR GEAR TOOTH.
2.    GEAR GRADE MEASUREMENT
2-1.MEASUREMENT POSITION
1)CURVE
TO MEASURE THE CURVES PROFILE OF 4 TEETH(LOCATED BEING OFF QUARTER ANGLE TO EACH OTHER) OF A GEAR AT THE MIDDLE OF FACE WIDTH AND IN ONLY ONE TOOTH OF 4 TEETH,TO MEASURE THE TOP AND BOTTO CURVES PROFILE POSITIONED BEING OFF 15% OF FACE WIDTH FROM EACH END (FRONT SIDE BE MARKED TO “TOP” AND REAR SIDE TO “BOTTOM”)
2) TO MEASURE LEAD PROFILE OF CURVE PROFILE MEASURE 4 TEETH ON THE OPERATING PITCH CIRCLE AND IN ONLY 1 OF 4 TEETH ALSO MEASURE TA THE TIPAND ROOT POSITION OF TOOTH PROFILE MEASUREMENT POSITION : ( TIP=   )  (ROOT= )
(TIP BE MARKED TO “TOP” AND ROOT BE MARKED TO “BOTTOM”)
2-2.MOUNTING DIRECTION OF GEAR FRONT DIRECTION OF TOOTH IS MOUNT TO UPPER DIRECTION OF MEASURING MACHINE.
2-3.DEFINITION OF DRIVE AND COAST SIDE.
3.CURVE ERROR
    1) CURVE PROFILE ERROR EXCLUDING PRESSURE ANGLE ERROR BE WITHIN THE LIMIT OFBELOW FIGURE AND CURVE PROFILE BE SMOOTH SHAPE.
    2)PRESSURE ANGLE ERRORIS MEASURED BY RELATIVE ERROR OF EQUAL AREA LINE BETWEEN 2 BASIC POINTS AND THE AVERAGE OF MEASURED VALUE OF 4 TEETH IS WITHIN THE SPECIFIED TOLERANCE DESCRIBED IN THE TABLE. HOWEVE, THE RANGE OF BIAS BE LESS THAN 11μm.
*NOTE
TOOTH TOP MUST BE ABOUT 5μ DOWN IN RELATION TO POINT b.
4.LEAD ERROR
1)LEAD PROFILE ERROR EXCLUDING HELIX ANGLE ERROR BE WITHIN THE LIMIT OF BLOW FIGURE
2)HELIX ANGLE ERROR IS MEASURED BY RELATIVE ERROR OF EQUAL AREA LINE BETWEEN 2 BASICPOINTS AND THE AVERAGE OF MEASURED VALUE OF 4 TEETH IS WITHIN THE SPECIFIED TOLERANCE DESCRIBED IN THE TABLE. HOWEVER, THE RANGE OF BIAS BE LESS THAN 12μm.

没有谁遇到过吗？谢谢了，如果谁遇到过类似的，请告知！

这是什么？什么测量仪器的测量报告，测量什么齿轮的
也不介绍清楚
看到英文就头大，

想帮忙，可惜是洋文
