Main structure parameters of small module gear shaping tools

The main structural parameters of the small module gear shaping tool are explained as follows, for reference and understanding.

Gear shaper cutters mainly have two structural forms: bowl, disc-shaped gear shaper and tapered shank gear shaper, as shown in the figure.

1. Small modulus gear bowl, disc gear shaper cutter:

2. Small modulus gear bevel shank gear shaper tool:

Small module gear bowl-shaped and disc-shaped gear shaper cutters have two nominal indexing circle diameters: φ40 and φ63.The main structural dimensions are shown in the table.

1. The structure parameters of the bowl-shaped and disc-shaped gear shaper cutter with the diameter of the index circle φ40mm:

2. The structure parameters of the bowl-shaped and disc-shaped gear shaper cutter with the diameter of the index circle φ63mm:

There are three kinds of nominal index circle diameters for small module gear bevel shank gear shaper cutters: φ12, φ16 and φ25.The main structural dimensions are shown in the table.
