The manufacturing technology of spiral bevel gear is closely related to the progress of machining machine tools. Since the appearance of spiral bevel gear machining machine tool, the tool inclination method has been introduced into gear machining, which is a major breakthrough in gear machining and manufacturing technology. With the optional variable mechanism of machining machine tool, the machining and manufacturing technology of spiral bevel gear is becoming more and more perfect, and some advanced gear meshing principles are also realized in practical machining. The centennial development history of Gleason technology comes from the emphasis on scientific research, especially the promotion of the development of computer technology. Before the 1970s, Gleason developed a complete set of new spiral bevel gear processing machine tools every 20 years. Among them, the mechanical gear milling machine represented by No.116 reached the top of its technology.
In the late 1970s, we developed numerical control gear milling machines no.2010, no.ll6cnc, etc. These machine tools are essentially the numerical control transformation of mechanical gear milling machines. Since 1985, mechanical gear milling machine stopped production and was replaced by CNC machine tools. In 1989, a brand-new Phoenix I CNC gear milling machine was successfully developed. The five axis linkage machine tool with X, y, Z, a and B coordinate axes replaced the previous shaking table structure and tool tilting and turning mechanism, which was an epoch-making revolution of Gleason machine tool. However, the overall layout of Phoenix I machine tool does not get rid of the pattern of No.116 special machine tool. At the beginning of this century, Gleason launched the column Phoenix II CNC machine tool. The advent of Phoenix II machine tool is another epoch-making revolution of Gleason technology, which shows the latest achievements of Gleason technology. Phoenix II machine tool adopts single column structure design, which makes the machine tool more compact and more rigid. It is at the top level in the world in terms of milling performance, ergonomics and maintainability of spiral bevel gears.
Matched with Gleason Phoenix, Gleason began to launch its advanced digital bevel gear manufacturing technology, Gleason bevel gear manufacturing expert system (GEMS). Gems system is an integrated manufacturing system based on computer network. It integrates the existing software modules of Gleason company, such as cage tm4win, g-agetm4win, summary manager, FEA and umctm, and realizes the information exchange and sharing between engineering workstation and Gleason CNC machine tool. Gems provides an efficient, seamless and collaborative bevel gear manufacturing system, provides an optimal solution for circular arc gear manufacturing, and represents the highest achievement in the field of circular arc bevel gear manufacturing. The development of Gleason technology is aimed at the automobile industry with mass production on the one hand, and the high-precision gears dominated by aviation and aerospace industry on the other hand. The gear grinding accuracy of Gleason spiral bevel gear grinding machine can reach above agmal 3. As shown in the figure, Gleason Phoenix series spiral bevel gear milling machine and gear grinding machine.
