Abstract
A pure-rolling generating measurement method and device for gear helix artifact is proposed, which use a dividing table to accurately control the linear rail slide block assembly component to rotate according to the helix angle of different base circle. The height of the measuring point is the installation height of the working plane of generating rails, so as to ensure that the measuring point is always located on the dividing cylindrical surface of the gear helix artifact. When the gear helix artifact does pure-rolling motion, the slide block performs high-precision linear motion on the working surface of two fixed rails; the pure-rolling motion is proportional to the high-precision linear motion, so that the inductor micro-displacement probe can complete the measurement of the helix deviations of the gear helix artifact with different base circle helix angle.
