For a project im doing in school i have to make a can crusher that works off a 9v motor.9v's seems a bit low to me but my teacher said its been done b4 of course he wont help me ha.ive searched online but thers very few exampes some youtube videos but i cant make out how they work.anybody know how i would go about making this?im thinking of using the motor attached to a high ratio gear train to push a piston against the can and the flat side of what im calling the crushing chamberwill this work?is ther away of getting more linear force out of a 9v motor?any help would be great thanksalso the device cannot exceed 300mm in any dimension.
The only other suggestion I'd have is do the math first. Figure out how much force it takes to crush the can once the side has been caved in, and how much torque the motor can produce, so that you know what your gear ratios need to be before you start building.
do you know how to connect a pump to motor? i would do something like that. not a real pump, just the pushing part of it, i would connect it to a wheel or something like that, which would connect to the motor. of course you have to lead the end of the pipe in tube. so it goes like this. you cut out a wheel of aluminium or wood. you connect the centre of the wheel to the motor. you take a stick, you fix it to the front side, near to the edge of the wheel. you make sure that the stick can turn around of its fixed point. to the other end of the stick you fix a wheel which is the size of the can. you hang the stick into a tube which can have a door for the can or something. you fix the whole thing, you have to do some math to know the geometry but no force or something i think it should work perfectely
