Designing a gearbox
Hi,
I am currently designing a squential gearbox for a high revving single seater racing car. The main internal parts are going to be taken from an old GP500 bike and the external casing is being designed from scratch. Does anyone have much knowledge on gearbox design? If so any tips on getting the design off the ground, what to investigate first, and possibly any good books or websites on the subject. |

Yes there are some good books specifically on the subject of making gearbox casings. One is called Gearboxes for Beginners Cant remember the auther but I think it was by Joe King or alternately go to how stuff works http://auto.howstuffworks.com/sequential-gearbox.htm

Further reading see "My first Gearbox" by F. Price. Hope this helps.

Have you considered dry sumping it to reduce the losses? I've just been looking over a range of really nice boxes that are all dry sumped, can save weight and size that way perhaps.

The engine its going to be attached to is a V twin.
Yeah dry sump is an idea we are looking at, centainly an advantage to reducing weight and losses. Any other tips? Thanks for the ideas on books, particularly the one by Joe King, i cant seem to find them on amazon have you got links to where i can get them please team78 and tone83?? |

I've also seen a very neat and light weight pneumatic shifter.

If you look on Amazon there are lots of books on gearboxes. below is a link to Mecanno Gearboxes. which you may find useful.
http://www.amazon.co.uk/exec/obidos/...927546-3256645 Have you thought about CVT? There are also articles in Race Car Engineering with regards to Gearbox design. Good luck |

Ideas from the loony bin suggest - Hydrostatic drive - so no gearbox in the classic sense...

How many gears are needed for the event? if only three then ditch the others as their simply being inertia being spun up. Ask your mum he should know

Thanks for the tips on areas to look at. Does anyone know where i can find or perhaps have any detailed drawings of any current or relatively new GP500/MotoGP gearboxes or similar designs?
Thanks |

http://www.kisssoft.ch/doku/kisssys/...geardesign.pdf
http://widget.ecn.purdue.edu/~me452/...all%202005.doc or try ingenta http://www.ingentaconnect.com/search...15&search.y=12 or http://uk.geocities.com/mikebull2001/veryfirstpage.htm I know the links are not directly linked to motorsport but they can guide you through how to approach the problem. couldnt find anything on the internals. try the manufacturer direct. thats your only real hope. |

kisssoft software is easy to use.
but what type of gears are sequential gearboxes? not the normal ones, or? gearbox calculation is mostly a lifetime problem i think. who long for example you need the first gear full loaded in your car? i think 1st gear in a normal streetcar is calculated about 30Min full load and many cars get very old with that |
