Ned Posted November 3, 2011 Author Share Posted November 3, 2011 That is a valid plan and i will see what to do. I can also make it smaller etc if i mount them scank on crank which is a likely candidate ATM Quote Link to comment Share on other sites More sharing options...
Truenotch Posted November 3, 2011 Share Posted November 3, 2011 I had a bit of an idea that involves a large shaft with multiple sprockets - would require spinning all the motors 90'. Motors mounted in thin air, but you get the idea. Left hand side will tension the bottom of the chain, right hand side will tension the top or visa versa.

Ned Posted November 3, 2011 Author Share Posted November 3, 2011 Still a large amount of side loading and makes the motor a lot larger but a valid idea will think of it some more Quote Link to comment Share on other sites More sharing options...
stingray Posted November 3, 2011 Share Posted November 3, 2011 Ahh the woes of transmission design. String all the motors together that you desire however, getting the power to the ground... Chains suck and clutches suck. Design it properly for intended use. Use belts that tighten under load. Akin to a ride on mower blade engage except use a uC Ned, you can.

flyingbrick Posted November 3, 2011 Share Posted November 3, 2011 Truenotch has the right idea! Quote Link to comment Share on other sites More sharing options...
grunta Posted November 3, 2011 Share Posted November 3, 2011 thats a super good idea!!! would be sweet abount of chain noise!!! there has to be some side loading in any setup u have ! all facing forward , jeah! Quote Link to comment Share on other sites More sharing options...
isnowi Posted November 4, 2011 Share Posted November 4, 2011 Tis a shame the crankshaft is not supported in both ends of the crankcase, could then couple all of the motors in one long line, no side loading then.. Quote Link to comment Share on other sites More sharing options...
sentra Posted November 4, 2011 Share Posted November 4, 2011 ^ then you end up with the last crank taking all 310 mighty cc's again /its a showpony engine, just strengthen / support what you have. even if it runs on the bench and never goes in a bike we wil think your cool.

anglia4 Posted November 4, 2011 Share Posted November 4, 2011 I had a bit of an idea that involves a large shaft with multiple sprockets - would require spinning all the motors 90'. Motors mounted in thin air, but you get the idea. Left hand side will tension the bottom of the chain, right hand side will tension the top or visa versa. I think this might be the only way it will work. This way each engine is individually loaded rather than the end motor seeing all the torques EDIT: But I think it might need a big more than an angle grinder gearbox. This thing should have massive stacks of grunt. Quote Link to comment Share on other sites More sharing options...
Truenotch Posted November 4, 2011 Share Posted November 4, 2011 Grinder box would be worth a go. I even have a second hand one sitting in the garage that I pilfered to turn into a tiny diff at some point. There's a guy around here who is big on scale model trains - he uses these as the CWP behind a petrol engine of some sort and tugs trailers around his property, so they can stand up to a bit of load. Possibly not 310cc and 100KG + though... Quote Link to comment Share on other sites More sharing options...
xsspeed Posted November 4, 2011 Share Posted November 4, 2011 Fuck Markku now you have me pondering uses for "that big old grinder thats too massive to use for >30secs" thats in my garage. Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted November 4, 2011 Share Posted November 4, 2011 Go to your local hobby store and buy 10 big model plane props and get hubs and spinners machined up by your machinist friends...then make something like this but with ten motors out front.
