Also hypoid gears are used in the trunk transmission of automobiles. As a result, the design and manufacturing of spiral bevel and hypoid gears occupy an important position in the machinery manufacturing area. The processing design of spiral bevel gears is paratively plicated, and meanwhile, the owners of the technology, such as Gleason corporation, are engaged in a technological monopolization Therefore, many countries are prompted to the technology research and exploration, and the spiral bevel gear drive in the design, manufacture and testing technology has been very active in the field of gear manufacturing. While domestic enterprises have developed several different series of spiral bevel gear NC Machines, the control kernel is the foreign NC systems, such as SIEMENS, FANUC and so on. It makes that the domestic spiral bevel gear design, manufacturing and other areas is still subject to few number of foreign monopolies, seriously hindering our manufacturing development. Combined with the home and abroad study of the spiral bevel gear tooth surface characteristics to milling machine can understand the mechanism 清華 大學(xué) 機(jī)械工程系 畢業(yè)設(shè)計(論文) III characteristics. through the study of existing machine tools and the tooth surface processing methods to explore, in accordance with the principle of meshing gears, I pleted to simplify the design part of the movemen of spiral bevel gear milling machine cutter axlet, as well as make some improvements of the traditional CNC spiral bevel gear milling machine body.
