Carbon gearbox anyone?

[chuntington101]

... Well not a totally carbon gearbox but an interesting idea for strengthening a stock gearbox. a 5mm 'sink' of carbon fiber!

So Andy / Tony / Tux, when you going to get around to trying this?

Looks like that thing is up here in Aberdeen, crazy idea but it might just work! Imagine doing that to our Noble box's!!

I think it would work. You are basically adding material to the case, which should make it stronger and help reduce flexing of the case.

Never seen it before so thought i would post it.

we usually use the same system on M3 ,S2000 driveshaft with good results....

we have 2 options : full carbon wich is the lightest,and machining lightened with carbon wrap wich is the cheaper option....

speaking about gearbox I think will work in the same way ....I'm planning various carbon reinforcement on the nob or kevlar to protect chassis from temperatures

Er, what?

Unless you can layup the carbon weave direction to match the shaft loading direction, and close enough to the source of those loads, what you are doing is just making a "thicker" casing, that is no stiffer (where it actually matters) but is heavier and a lot of pfaff!

Much better to machine internal steel "cross shaft" plates to take the gear loads. And of course, once you make the casing stiffer, then you need to increase the shaft stiffness and the gear root strength to be able to "use" that extra strength.

Sorry, but what it adds up to from an engineering perspective is a total waste of time / money!

That's nothing compared to this:

I'm not entirely agree....ok,is not the final solution to make our boxes bulletproof,but in union with shoot peening and other reinfrcement of the gears,may help


I've worked on costruction of big turbines and turbo fans...and increase the thickness was the first step,whe the housing of the turbine or the transmission showed weakness or resonance
plus the strenght of the carbon may reduce the resonance (would have to be tested how much)

..you can also combine different directioned layers of carbon or carbo/kevlar
