GearPro internally uses a new 3D model of the entire gear. This robust model
makes it possible to carry out measurements without complex path control
systems, because the tooth flank is always evaluated as a spatial surface and
never as an intersection. As far as the machine accuracy is concerned, gear
measurements are also possible with manually operated measuring machines. BR>
The basic idea of the surface model is to measure the tooth flank, comparable to
any other form element (e.g. cylinder), with a sufficient number of points and
to model it as a geometric substitute element via the best-fit calculation
method. Based on the measuring points, the compensating flank surface or also
the entire toothing (in the case of involute spline) is calculated via the
compensating calculation method according to Gauss, minimum zone or
circumscribed or inscribed conditions.
From the parameters of the involute surface, all derived gear parameters (ball
dimensions, span widths, pressure angles,….) can be calculated via the exact 3D
calculation method. Furthermore, this considerably facilitates measurements of
profile, tooth trace and pitch deviations.
