Machining Technology of High Precision Spiral Bevel Gear

The processing principle of high-precision spiral bevel gear: the simulation wheel is the processing gear, and the unified chuck is the imitation gear tooth. When the simulated wheel is combined with the breaking element, the cutter head cuts off the gear teeth. How to deal with large and small wheels, calculating the correct value is the main problem that needs to be solved. Many experts and scholars at home and abroad have done a lot of research and published a lot of papers and professional work, especially for arc bevel gears and reduced-tooth hypoid gears. Since the large and small wheels are processed into flat-top production wheels, their orientation and curvature need to be calculated, and the contact analysis is very complicated, and it is difficult to obtain ideal results in reality. With the popularity of controllable gear machine tools and grinding technology, the processing methods of gear systems in my country have developed rapidly. They both use high teeth, like cycloids, with simple calculations and better contact area than constriction. The results show that the use of circular arc contour teeth is an ideal choice in the processing of small batch products, especially in the processing of high-precision spiral bevel gears.

Theoretically speaking, the machining of high-precision spiral bevel gears is completely universal, so theoretically there is no need to calculate the direction and curvature of the vector, and its complexity is equivalent to the axis value. Therefore, simply comb three gears with the basic condition of the same height as the arc wheel, also known as the arc wheel. Viewed from the side, it is a flat gear. Its research and development principle is to polish the high teeth on the basis of the swing arc. In the process of processing, the factory usually cuts a small amount of gear "contact area" in production mode according to the plane of the gear as a starting point, and combines the cutting machine with the shaft to realize the processing of shrinking gears.

Theoretically speaking, large-scale high-precision spiral bevel gear processing technology requires three necessary conditions, namely, the determination of the pressure part, the determination of the helix angle and the cutting of the tool radius. They are the basic structure of gears. As far as the radius of the cutter head is concerned, attention should be paid to the installation position. The installation of the cutter head is mainly based on the rotation of the cutter body, and the slash is the side view. The movement of the knife is also an important part. This is a technical method of a parallel device with the eccentric roller as the core. Particular attention should be paid to the position of the tool. This is based on the axial handling of the fan turntable and the moving parts box as the carrier. It is also important to adjust the position of the cutter head. Each knife face has a balanced cross-section, and the position of the cross-section point is the center of the machine, which carries the processing gear. The manufacturer should move along the axis of the bed base and install the entire fan shape on the rollers. The installation standard should adjust the angle of the bell gear according to certain parameters. This parameter is mainly obtained from the mechanical gear on the milling machine. We use designed gear.
