Z = number of teeth h= thickness of the cog-wheel (gear) m= normal modulus.
Pitch diameter= z*m Outside Diameter = m*(z+2)
This cog-wheel (gear) have a circular hole of 2mm for the axis It’s a simple SPUR cog-wheel (gear)
/ ! \ 2 cog-wheels working together must have the same « m » (normal modulus) the ratio is given by Z1/Z2
If you didn’t find the cog-wheel you were looking for, send me a e-mail to : cube77-3D@hotmail.com with Z, h, m and other expectation
