Internal gear is a gear with its teeth cut in the internal surface of a cylinder and meshes with spur gears. In its manufacturing, the usual hobbing machine used in spur gear production cannot be used because of its shape. Generally, it is made with a gear shaper (or gear shaping machine) equipped with a pinion cutter.

Pinion Shaping
Pinion shaping is the process of cutting internal teeth in gears using a pinion shaping machine. This method involves using a pinion cutter that is shaped to match the internal teeth of the gear.
Hobbing, Rack Planning, and Milling
- Hobbing is a gear cutting process that is used for external teeth, not internal teeth.
- Rack planning is a process used to cut straight teeth on a gear rack, not internal teeth in gears.
- Milling can be used for both internal and external gear teeth, but pinion shaping is specifically designed for cutting internal teeth in gears.
Advantages of Pinion Shaping
- Pinion shaping allows for precise cutting of internal gear teeth, ensuring a high level of accuracy.
- The process is efficient and can be used to produce gears with complex internal tooth profiles.
- Pinion shaping machines are designed to handle a wide range of gear sizes and types, making them versatile for various applications.
Conclusion
In conclusion, the correct method for cutting internal teeth in gears is pinion shaping. This process is specifically designed for internal gear teeth and offers advantages such as precision, efficiency, and versatility.
