1、中文 3900 字 Bevel gear of the latest developments in measurement technology 1 Overview Bevel gear drive mechanism in the car, helicopter, machine tools and electric tools manufacturing industry, has been widely used. The use of different performance of the bevel gears are also different quality requir

2、ements, can be summarized including: a good contact area, can be a reliable torque transmission power； good match geometry, a smooth transfer of the movement, in order to ensure uniform load , transmission smooth, vibration small, noise low. Factories are usually small devices and dual-spot detectio

3、n of rolling contact tester to control the quality of bevel gear, but in reality it is very difficult to determine accurately the performance of the bevel gear. Bevel gear and the precision of measurement of cylindrical gears similar, can generally be classified into three types: Coordinate Geometry

4、 Analysis of measurement type. That is, the bevel gear as a geometric entity, its geometric elements, respectively, the geometric precision of individual measurements； Gear Measuring Center is the main measuring instruments. Comprehensive engagement measurement accuracy. That is, the bevel gear tran

8、 as the geometric precision of the individual. Therefore, the overall error of measurement of bevel gear is a measurement of the first two methods of integration and development. With the coordinate measuring technology, computer control and measurement technology, in recent years, the overall error

9、 of measurement of bevel gear technology research development soon. Gear Measuring Center as a result of multi-cylinder coordinates, such as multi-function measurement instrument performance, data-processing capacity, bevel gear-type coordinates of analytic geometry measurement technology, has been

10、the development of a single geometric error of measurement to the overall error of measurement of bevel gear, improved cone gear design, processing, quality testing to determine the accuracy and the use of the forecast performance of the bevel gear, such as the level of manufacturing technology. By

11、Chinas own development, based on the control point movement - geometric measurement principle on one side of the bevel gear meshing point scanning technology and technology development based on the overall error of the bevel gear measuring instrument, it is more towards the production of the first l

13、a straight bevel gear-type coordinate measuring instrument there earlier products to represented KP42-type, but the complex structure of high accuracy. Since 1990, both before and after, CNC Gear Measuring Center to the market, coordinates arc bevel gear-type geometry of measurement error is the rap

14、id development and popularization and application. Todays market, Gear Measuring Center from abroad, whether it is Klingberg Germanys P63, or the United States Gleason / mar the GMX275, M & Ms Sigma 3, have been measured with the function of bevel gear. These instruments have reached VDI / VDE level

15、 provided a space measuring uncertainty for more than 2 microns； bevel gear on the geometric error of a single test, such as pitch deviation (including single pitch deviation, the cumulative pitch deviation , total cumulative pitch deviation), tooth profile deviations (including a total deviation of
