Re: pic: Team 192's 2013 Gearbox
I was waiting to see this. Always love 192's gearboxes. Can't wait to see this things in-person at SVR.
Just curious - why the tiny output shaft? That looks like it could barely hold a sprocket. |

Wow. That's absolutely beautiful. I assume you're using bevel gears?

Ah, that makes a lot more sense.

Re: pic: Team 192's 2013 Gearbox
Is it a worm drive inside or plain bevel gears?

More specs, two speed shifting 17fps and 6fps Cim to cluster shaft is 3mm GT2 Belt and yes, there is a bevel gear in there. |

Re: pic: Team 192's 2013 Gearbox
Just wondering, do you have any idea about the gearbox's efficiency? Just looking at all those shafts makes me wonder if you're loosing some power through all those reductions.
But seriously, that looks like a marvel of smart design and good machining. So many bends and bearing holes, all lining up perfectly... |

Re: pic: Team 192's 2013 Gearbox
How are you getting such high efficiency per stage?

Re: pic: Team 192's 2013 Gearbox
The main reductions are spur and bevel gears, which, when alined properly with accurate tooth profiles and proper lubrication are extremely efficient. Once again I have no measured data to support these estimates, they are based on subjective observations and engineering manuals (mostly engineering manuals).
