Do you know the principle and characteristics of precision gear shaping? Let's discuss it together today.
What is the principle of gear shaping?
Gear shaping is achieved by meshing a pair of gears. This process uses special gear shaping cutters, which cut the front angle and back angle on the tooth surface of the gear to form a gear with a cutting edge. The cutting edge of the gear shaping cutter cooperates with the enveloping process of the tooth profile to complete the processing of the gear tooth profile.
What are the characteristics of gear shaping?
1.Modulus compatibility
Gear shaping cutters can process cylindrical gears with the same modulus but different numbers of teeth, which is similar to the hobbing process, so they have good adaptability.
2.High precision
Gear shaping has a higher precision than hobbing, which can ensure the application of gears under high precision requirements.
3.Adapt to complex shapes
Gear shaping can efficiently process internal gears and multi-gears, which are difficult to process using the hobbing process.
4.Smooth tooth surface
During the gear shaping process, the gear shaping cutter continuously cuts along the entire length of the gear tooth surface, so the tooth surface roughness is low, and a smoother tooth surface quality is obtained.
5.Lower productivity
Compared with gear hobbing, gear shaping has lower productivity and is suitable for situations where high precision is required but the production quantity is relatively small.
Through the above analysis, we can see that although gear shaping has higher precision, it is inferior to gear hobbing in production efficiency, so it is suitable for precision gear processing with some special requirements.
