Z = number of teethh= thickness of the cog-wheel (gear)m= normal modulus.
Pitch diameter= z*mOutside Diameter = m*(z+2)
This cog-wheel (gear) have a circular hole of 2mm for the axisIt’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
