# Chain Sprockets ISO606 simplex 1/4" x 1/8" from z 8 to z 40 This folder contains the 3D models of the sprockets for ISO 606 chains simplex 1/4" x 1/8" with number of teeth ranging from z=8 to z=40. ![Image](screenshot.png "Sprocket Simplex") All models are parametric and the values are contained in the spreadsheet `Data`. The parameters refer to the sprocket dimensions as in the drawing below: ![Drawing](drawing.png "Drawing") 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 (Hub diameter)|D (Hole diameter)|H (Total height) ---|---|---|---|---|---|---|---|---|---|---|--- 6,35|3,18|3,3|6,4|0,7|2,9|8|9,4|16,58|10|6|12 6,35|3,18|3,3|6,4|0,7|2,9|9|21,4|18,56|11,5|6|12 6,35|3,18|3,3|6,4|0,7|2,9|10|23,3|20,55|13|6|12 6,35|3,18|3,3|6,4|0,7|2,9|11|25,3|22,54|15|8|13 6,35|3,18|3,3|6,4|0,7|2,9|12|27,3|24,53|17|8|13 6,35|3,18|3,3|6,4|0,7|2,9|13|29,3|26,53|17|8|13 6,35|3,18|3,3|6,4|0,7|2,9|14|31,3|28,53|17|8|13 6,35|3,18|3,3|6,4|0,7|2,9|15|33,3|30,55|20|8|13 6,35|3,18|3,3|6,4|0,7|2,9|16|35,3|32,55|22|8|14 6,35|3,18|3,3|6,4|0,7|2,9|17|37,3|34,55|22|8|14 6,35|3,18|3,3|6,4|0,7|2,9|18|39,4|36,56|25|8|14 6,35|3,18|3,3|6,4|0,7|2,9|19|41,4|38,58|25|8|14 6,35|3,18|3,3|6,4|0,7|2,9|20|43,4|40,58|25|8|14 6,35|3,18|3,3|6,4|0,7|2,9|21|45,4|42,6|30|8|14 6,35|3,18|3,3|6,4|0,7|2,9|22|47,4|44,62|30|8|14 6,35|3,18|3,3|6,4|0,7|2,9|23|49,4|46,63|30|8|14 6,35|3,18|3,3|6,4|0,7|2,9|24|51,4|48,64|30|8|14 6,35|3,18|3,3|6,4|0,7|2,9|25|53,3|50,66|30|8|14 6,35|3,18|3,3|6,4|0,7|2,9|26|55,5|52,67|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|27|57,5|54,69|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|28|59,5|56,71|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|29|61,5|58,73|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|30|63,6|60,75|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|31|65,6|62,76|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|32|67,6|64,78|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|33|69,6|66,8|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|34|71,6|68,82|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|35|73,6|70,84|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|36|75,6|72,85|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|37|77,7|74,87|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|38|79,7|76,89|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|39|81,7|78,91|30|8|16 6,35|3,18|3,3|6,4|0,7|2,9|40|83,7|80,93|30|8|16
