This is a gear with 15 straight teeth, normal module 4, pressure angle equal to 20° (external toothing)
The gear has an hexagonal hole that permits to join it to an hexagonal shaft to recive or to give motion transmission.
Teeth profile accomplishes to technical norms: involute profile permits to this part to be successfully coupled to other gears of the same module (Mn=4).
Robotics as for any project that requires motion transmission needs customized gears. Ask for Your personal needings: Studio BitLab will generate the project and supply the physical object printed by Shapeways.
