Hi,
I'm working on my thesis and I need a way to 'connect' the axis of a pendulum to the axis of an encoder...
Since there is no space to mount the encoder on the same axis as the pendulum I figured the best way to make them perpendicular would be gears.
But, because the pendulum only makes very small movements (<20° from center) I thougt it would be best to use herringbone gears for there increased contact surface and at the same time I could 'multiply' the movement of the pendulum to get a better reading on the encoder.
I'm using Creo parametric 2.0 (student edition)
Everthing is set to mm...
These gears/files are intended to use for 3D printing
The only problem is that I don't have very much experience using Creo, I've certainly never worked with relations of parameters before.
I've managed to make a gear as in this tutorial: Helical gear in ProE - YouTube
But when I try to change the gear to the specifications I need, it fails to regenerate.
I hope that someone can either explain to me how to correctly scale this down or otherwise point me in a direction where I could find some pre drawn gears or a generator.
Otherwise if someone would be so kind as to draw some for me;
The smallest gear fits on to an axis of D=6mm, and can be as small as it can be made to fit on this axis, the larger gear can then be scaled up accordingly to get a transfer ratio of 2 or 3.
As stated before, I'm using Creo parametric 2.0 (student edition)
and the parts are intended for 3D printing (so the teeth can't be too fine)
Thanks in advance,
Niels
