Research on Measuring the Gear Surface of the Worm Pair

Abstract

The profile error of the gear surface of worm produces a great impact to gear characteristic. So, it is necessary to calculate the profile error of the gear surface. In order to develop the manufacturing accuracy of the complex tooth surface of the worm pair, a method to measure the error of the worm was designed in this paper. The profile error of the worm can be calculated based on geometrical operation. To meet the need of quality-controlling and the intelligent machining, the 3-D measuring technology method was adopted to measure the surface of the worm. And through the calculation, analysis and reconstruction, the real outline of the worm pair is redrew. A whole theoretical solid model of worm’s meshing surface with grid can be obtained based on the mathematical modeling. And it is possible to give the data of the recorrection and the feedback by analysing the profile error.
