The use of disc-shaped modulus milling cutters or finger-shaped milling cutters to mill teeth belongs to the forming method, and the cross-sectional shape of the milling cutter teeth corresponds to the shape of the gear teeth. This method has low processing efficiency and processing accuracy, and is only suitable for single-piece small batch production.
Do you know the processing methods of gears? Let's follow the good price and quality Spur Gears editor for a brief understanding!
1. Milling teeth
The use of disc-shaped modulus milling cutters or finger-shaped milling cutters to mill teeth belongs to the forming method, and the cross-sectional shape of the milling cutter teeth corresponds to the shape of the gear teeth. This method has low processing efficiency and processing accuracy, and is only suitable for single-piece small batch production.
2. Form grinding
It also belongs to the forming method. Because the grinding wheel is not easy to dress, it is used less.
3. Hobbing
It belongs to the generation method processing, and its working principle is equivalent to the meshing of a pair of helical gears. The prototype of the gear hob is a helical gear with a large helix angle. Because the number of teeth is small and the teeth are very long, a worm with a small helix angle is formed around the shaft. Hob for cutting edge and clearance angle.
4. Shaving
Shaving is a commonly used finishing method for non-hardened tooth surfaces in mass production. Its working principle is to use the shaving cutter to freely mesh with the gear to be processed, and to shave off very fine chips from the tooth surface by means of the relative slip between the two to improve the accuracy of the tooth surface. The shaving teeth can also form drum-shaped teeth to change the position of the contact area of the tooth surface.
5. Gear shaping
Gear shaping is a gear cutting process commonly used in addition to gear hobbing using the generating method. When gear shaping, the gear shaping cutter and the workpiece are equivalent to the meshing of a pair of cylindrical gears. The reciprocating motion of the gear shaper is the main motion of the shaper, and the circular motion made by the shaper and the workpiece in a certain proportion is the feed motion of the shaper.
The above is the small series of good price and quality Spur Gears: a brief introduction to the knowledge of gear processing methods.
