Comparison of the characteristics of common and full-cut gear hobbing methods for small module gear hobbing

The comparison of some characteristics of the ordinary gear hobbing method and the full-cut gear hobbing method of the small modulus gear hobbing method is as follows, for reference and understanding.

First of all, according to the different hobs used, there are two kinds of small-modulus gear hobbing methods, which are the ordinary hobbing method and the full-cut hobbing method.

1. Features of common hobbing method:

The top edge and side edge of the rolling door are used for cutting, the tooth tip circle of the workpiece is not hobbed, and the original size of the hair is still maintained.

2. Features of full-cut hobbing method:

For the hob used, the top edge, side edge and bottom edge of its teeth all participate in hobbing.

Full-cut gear hobbinggear, Its addendum circle is shaped by one-time hobbing of its tooth profile, so its gear accuracy is higher than that of ordinary gear hobbing.

However, for full-cut gear hobbing, because the bottom edge participates in the cutting, the cutting load increases, which increases the difficulty of hobbing and hob manufacturing.

The above is a comparative description of the characteristics of common and full-cut gear hobbing methods for small module gear hobbing, including but not limited to, if you have more questions or related needs, you can consult EP free of charge.
