1. a Novel special large gear on-position measure method, is characterized in that, comprise the following steps:

  • (1) gear on-position measure device is moved to by tested gear, be adjusted to the position being applicable to measuring the flank of tooth;

    (2) prototype gear tip cylinder, to measurement point matching cylinder, to obtain axial equation;

    Using the Z axis coordinate of this axial equation as tested gear;

    Prototype gear end face, to end surface measurement point fit Plane, will measure the intersection point of fit Plane and the fitting circle mast axis obtained, as the true origin of tested gear workpieces coordinate system;

    Measure the flank of tooth a bit, by this point in conjunction with described axis and fit Plane;

    Build super-huge gear workpieces coordinate system;

    (3) according to step (2) according to constructed tested gear workpieces coordinate system, each tooth of tested gear is measured in segmentation successively, can realize tested gear local the flank of tooth measurement;

    (4) mode adopting transposition to measure, moves to new measuring position by measurement mechanism ,repeat above step, until complete the measurement of tested gear institute geared surface.
