Hello,
This is the mechanism in question, explanation follows:
The circles are gears.
The black part is controlled by a DC motor.
The red gear has a couple of sequential (?) teeth missing.
The gold part tightens (?) a spring.
When the toothless part of the red gear is at the gold gear, the mechanism fires.
My fear is that there is the possibility that the top lands of the red and gold gears will be pressed against eachother when the mechanism tries to fire again, and that this will break either the gears or the motor.
Let me know if you need more/better clarification.
My questions are:
Is this a good mechanism?
Is there a better (not too expensive) mechanism?
Is it possible to improve this mechanism?
I'm too scared to order the parts and try it out because the mechanism can break.
Thank you very much.
