Staton 3.11 on a GEBE

Timming Belt Drivetrain

Yes I'm putting together drivetrain using Metric Timing Belts. photos can be seen at this link http://www.motoredbikes.com/showthread.php?t=7580&page=3 The system begins with a clutch from Max-Torque that has a 23t 5mm HTD driver attached to the clutch bell instead of a chain driver. this drives an 86t pulley on a jackshaft that also has a 20t driver that then drive the final 96t rear pulley on the rear hub. The belts are 25mm wide. The larger pulleys are from an outfit called Pfeifer Industries. Based on the HP generated by your engine I'd think that if you wanted to go with a toothed belt drive you would be better served using 8mm HTD rather than 5mm http://pfeiferindustries.com has a full range of pulleys, drivers, and belts that would make such a drivetrain possible. They are a big supplier to the go-kart racing industry.

hello appye thank god i found your post what else do you know about the 3 to 1 staton gb?

especially where are the output sprockets on the staton website??
 
Yeah, I basically created a new post because I am wanting to mount it on a GEBE. As far as the sprockets, I would get them elsewhere from staton, just because staton does not seem to have much for the driven sprocket as the ratios would be too low. The largest they have is like 40 teeth or something.

ocsully, that is definately an interesting build. A lot more complicated than what I would want to venture into though at this moment. I like rack mount solutions a lot more because I like that they are more universal in the sense that you can move them from one bike to another pretty easily without too much modification to the bike. Yours will be one serious machine though.
 
ocsully: agree with appye.. but serious pionts for CUSTOM.

appye: no probs but what about the output sprocket for the staton gb. any ideas?

I wasn't trying to say that the system I 'm working on was the answer to what you are trying to accomplish. I was trying to point out that there a parts available to keep a belt drivtrain rather than having to switch to chains, if you so desired. 8mm HTD X 20mmwide belt would handle the HP from the 460 motor and putting an 8mm HTD driver on the 3.11 gear box would be simple then all you would need is the approiate size pully for the rear wheel. I'm really partial to the Metric Timing Belt type of drivetrain as they are so much quiter, cleaner and I feel transfer power better than chains. I think that what GEBE offers is a great system but is right at the edge of what a 5mm HTD 9mm wide belt can handle with the motors they offer. When you double the HP the belt becomes a very short lived item.

Amen to the teensy belt for a gp460...

Anyway, I was not saying that your build was a solution to my project, so much as I was complimenting you for your work. I am still considering the idea of a bigger belt and a hub mounted pulley of some kind. I definitely recognize the advantage of belt systems. I will admit that I was not able to get too far with pfeifferindustries.com though, as the whole website seems to be a bit incomplete.

There is one big disadvantage to a belt system that may or may not be such a big deal though. I would think that belts are much more sensitive to misalignment than a chain would be. Flexible chains are designed to be able to work fine when the drive and driven sprockets do not line up perfectly, whereas belts are not. I am thinking that is a big reason my first belt shredded so quickly, because it was not aligned so perfectly, and that put a lot of lateral tension that the belt did not like. Keeping things lined up correctly may not be such a problem with a smaller pulley that is so much closer to the hub though.

The Pfeifer web site is not the easiest to navagiate your way aroundr, but there is alot on information there, and if you contact them by either e-mail or phone they are great to deal with and have alot of experience doing custom one off drive systems. The contact people at Pfeifer are eithe Jim Donavan Jr. or Brian. Contact them with a brief discription of what you want to do and they will be more than willing to help. Be sure and mention the HP of the engine you are using. The bulk of the information about what Pfeifer has is located in their Technical section. Here is there listing of what pulleys they have in 8mm HTD http://www.pfeiferindustries.com/pdfs/timingbeltpulley/8mm_HTD_PD_OD.pdf The two large pulleys for my project were purchased from Pfeifer and they cost approx $45.00 each. The smaller steel drivers are about $20.00 more. But you can get less expensive drivers from McMaaster Carr
 
hmmm. only 8mm? That does not seem like much of an improvement in strength over the GEBE belt. I am wanting something that is like a solid inch wide or something. I guess I would be getting in the way of the stays with that though...
