Engineering Problem

[sam_t]

If the load is going to be a problem how about having the output from the gears drive the disk via a belt, and take a bit of the hurt out of the drivetrain.

an angle grinder gearbox would prbably be the simplest thing. they are designed for very high speed 1:1 gearing, but i dont have much of an idea about the shock at load they can take.

Just thought you guys might like to see what Im planning to put on the new machine. (Check profile) That is nearly 3Kgs of 6mm thick Chrome Vanadium steel 345mm in Diameter.

Oh no fair lol! S28-150 Magmotor and a 3Kg Pussycat type blade!

you burgled mr Gribble Geoff?

To be honest, Id ask a professional, well established engineering company to come up with a solution for you geoff, you could waste a lot of time/money trying some of the solutions above only to find they wont work.

Failing that, contact Red Bull racing and ask for a titanium differential gearset.... should be light enough and strong enough. bit of WD40 on to grease it.... lol.

I would go for the spiral bevel gears mod.2 or for helical gears. Also mod.2 Check this website, im sure they can give some advice.

If anyone is going to ask there for some prices, please ask for me the price of a toothed bar stock, 15 teeth, mod. 0,7 in brass and steel. This should be the same size of gears as in my cordless drill gearboxes. Then i can cut them to the lenght i want and put a bigger motor on the gearbox.

I would stop giving Geoff advice

Never mind that Ed, have you noticed Little Spinner yet? I hate to think what Graeme has come up with this time

How far did you get with this in the end Geoff?

It looks like somebody else had the same issue at around the same time but on the other side of the pond: http://www.buildersdb.com/botdetails.asp?botid=4290http://www.buildersdb.com/botdetails.asp?botid=4290
Dick got the power through 90degrees using friction drive with a colson on the mags output shaft. Given he destroyed everyone at Motorama I assume it worked quite well..
