The principle and characteristics of precision gear shaping

Immediately beforePrecision gear hobbing, Now continue to share the relevant content of the characteristics of gear shaping processing principles, respectively as follows, for reference and understanding.

Precision gear shaping needs to be carried out on a gear shaping machine, and the machining accuracy is higher than that of gear hobbing. The principles and features are explained as follows:

XNUMX. Gear shaping principle:

Use a pairgearThe principle of meshing realizes gear shaping.

The gear shaper is a gear that has a cutting edge by grinding the rake angle and the back angle on the gear teeth.The envelope process of the tooth profile is shown in the figure.

5. Five characteristics of gear shaping:

1. Gear shaping is the same as gear hobbing. Gear shaping cutters with the same modulus can process different gears with the same modulus.Cylindrical gear.

2. The precision of gear shaping is higher than that of gear hobbing.

3. Gear shaping can process internal gears and multiple gears that are difficult to process with a hob, but it is not as convenient to process helical gears as hobbing.

4. When gear shaping, the gear shaping cutter cuts chips continuously along the full length of the gear teeth, so the tooth surface roughness is low.

5. The productivity of gear shaping is lower than that of gear hobbing.
