Chain Plate Wheels ISO606 simplex Simplex 1" ¼ x ¾" from z 8 to z 30

This folder contains the 3D models of the plate wheels for ISO 606 chains simplex 1" ¼ x ¾" with number of teeth ranging from z=8 to z=30.

All models are 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)
