[0036] The present invention will be further described in detail below in conjunction with the drawings.
[0037] Such as Figure 1 ~ Figure 7 As shown, in the specific implementation, first use the on-machine measurement system to measure the standard gear corresponding to the gear to be measured, and determine the error value at each measurement point when the on-machine measurement system measures the tooth profile of the standard gear. The specific steps are as follows:
[0038] 1. Positioning probe coordinates
[0039] Such as figure 1 As shown, when measuring the tooth profile of a standard gear, the projection of the common normal of the tooth surface and the probe spherical surface on the end surface is the normal of the end surface involute, and the radius of the gear base circle is r b , The radius of the probe is r k , The helix angle of the standard gear is β b , The spread angle at any measuring point on the standard gear tooth profile is ε. The center point of the pro...
