# Chain Plate Wheels ISO606 simplex Simplex 2" x 1" ¼ from z 8 to z 30
This folder contains the 3D models of the plate wheels for ISO 606 chains simplex 2" x 1" ¼ with number of teeth ranging from z=8 to z=30.

The model is parametric and the values are contained in the spreadsheet `Data`.
The parameters refer to the plate wheel dimensions as in the drawing below:

### Table of dimensions in millimeters:
P (Pitch)|Wc (Chain width)|Dr (Roller diameter)|Tr (Tooth radius)|Rw (Radius width)|Wt (Tooth width)|z (Number of teeth)|De (External Diameter)|Dp (Pitch diameter)|D (Hole diameter)|H (Total height)

The 3D model configuration of each plate wheel can be dynamically retrieved using a preset `Configuration table`.
The file name of the 3D model containing the `Configuration table` is **`Plate Wheel simplex 2 x 1 ¼.FCStd`**.
To obtain the 3D model of the desidered plate wheel, click the spreadsheet `Data` in the Tree View and then select the `Teeth Number` in the property editor. If nothing changes try to `Refresh` the model.
See the following image for details

### Notes for developers
If you add a row in the `Configuration table` of the `Data` spreadsheet, then add that row in the above table of this `README.md` file, without the first cell.
