It is believed that the meshstyle points based on scanning the overall error of measurement of bevel gear technology, the establishment of precision bevel gear bulk products database, it is very possible to adopt in accordance with the use of puterassisted measurement technique to achieve automatic arc bevel gear pair quickly. 錐齒輪測量技術的最新進展 1 概述 錐齒輪傳動機構在汽車、直升飛機、機床及電動工具制造業(yè)中， 得到了廣泛的應用。 the actual processing of the large gear tooth surface with the ideal gear tooth surface processing pare measurements to detect gear tooth profile and the relative deviation upward。 reengagement model in accordance with TCA analysis, calculated by the bevel gear pair integrated deviation and tangential contact conditions, test whether or not to meet the requirements. If necessary, the corresponding software will be based on the measurement results, recalculate and adjust the machining parameters in order to retry all they can be processed into a more satisfied with the quality of products. (2) coordinates of point scanning type bevel gear of the overall measurement error Seiki, Osaka, Japan recently proposed using twodimensional measurement of bevel gear tooth surface measurement to point scanning method has been satisfactory and reliable results. This method has the following characteristics: the workpiece by controlling the rotation, the parallel displacement of probe movement, to avoid the probe and the tooth surface friction between the adverse effects of measurement。 through the use of acceleration sensors, pickup of vibration and noise measured on the tooth scan frequency harmonic detection. This method is quasidynamic measurement method, which bevel gear for the accuracy of detection is far from plete or accurate enough. Optical encoder used as the base point of view, to cut bevel gears for the accuracy of detection of the integrated singlesided meshing bevel gear tester, such as Germany39。s P63, or the United States Gleason / mar the GMX275, M amp。 Gear Measuring Center is the main measuring instruments. ② Comprehensive engagement measurement accuracy. That is, the bevel gear transmission as a ponent, the accuracy of their transmission, contact spots, a prehensive measurement of the vibration noise. The measuring instruments are mainly onesided meshing bevel gear tester, bevel gear meshing twosided bevel gear measuring and inspection machine rolling. Bevel Gear ③ the overall measurement error. It will bevel gear transmission as a function for the realization of the geometric entities, or by coordinate measuring method in accordance with the geometric precision of a single measurement to measure the overall error of bevel gears, beve
