l error of the bevel gear measuring instrument, it is more towards the production of the first line, so that China Bevel Gear measurement theory, the practical application of measurement technology has been further improved and developed. main bevel gear precision measurement method and apparatus Coordinatestyle geometric measurement and analysis equipment Machinery Exhibition into a straight bevel geartype coordinate measuring instrument there earlier products to represented KP42type, but the plex structure of high accuracy. Since 1990, both before and after, CNC Gear Measuring Center to the market, coordinates arc bevel geartype geometry of measurement error is the rapid development and popularization and application. Today39。s Sigma 3, have been measured with the function of bevel gear. These instruments have reached VDI / VDE level provided a space measuring uncertainty for more than 2 microns。 the other for the matingtype movement measurement geometry (ie, meshtype scan measurement point, the method for our first), the apparatus used for singlesided meshing bevel gear tester, equipped with a dedicated measurement bevel gear and measurement software package. (1) coordinate the overall bevel geartype pointtopoint measurement error Gear Measurement Center in, along with threedimensional measurement of bevel gear tooth profile and tooth to the two directions, according to a predetermined interval, the detection of the measured points of the tooth surface (usually the 5 tooth profile, tooth up 9 a total of 45 points) for the geometry error of measurement of points. This method can be avoided and the measured threedimensional probe in the measurement of tooth surface when the impact of friction and the measurement results. The measurement method is based on direct measurement principle, concrete steps are: first bevel gear in accordance with the adjustment of machine parameters and tool geometry parameters to be processed by calculating the large and small bevel gear tooth surface ideal geometric processing parameters。 measurement path can have a wide range of choices, usually tooth number and tooth number of each to the three, a total of six。 by the putation of the corresponding deviations workers Bureau data (that is, relative to the workpiece bevel gear partial cone base Gear indicator of the corresponding deviations of the accuracy). And then measured in accordance with the Public Works Bureau deviation of the accuracy of data and indicators for the development of tolerance, to determine the bevel gear of the level of quality and interchangeability. Bevel gear overall error measurement method is simple, fast and reliable measurement informationrich, especially for mass production. As a result of measurement must be measured using special gear, so this method should not be used for a single measurement of small quantities. However, since the bevel gear at the same time the overall error of measurement also has a rolling bevel gear tester, so it can be used for singlepiece and smallbatch precision bevel gear Deputy prehensive detection and production of the test workpiece and cutting tool debugging. 3 Conclusion Through the bevel gears in recent years the field of measuring the status of technology research and development, both at home and abroad to highlight the overall error of measurement of bevel gear technology, methods and development of the corresponding equipment.
