OK, I have been spending countless hours combing the internet for viable suppliers of gearbelt pulleys. Here is a list of all the links I have come across. Please feel free to add to the list if anybody knows of others. :wink:

Nice list :) Would love to have a pulley setup on my trike but sourcing the corect sizes pulleys/belts is a pain in da ass...i would prefer buying local so i can see the the items but have had no luck finding anything remotely close for the larger pulley, motor size pulleys no probs...

Cheers

why does the link for SDP/SI have a sad face? that's where I get my sprockets, pulleys, and belts from and they've been great.
here's a better link though: https://sdp-si.com/eStore/
 
Dammit Mud! Where has that link been? I was not aware that they had an e-store that any schmuck could order from, thanks. :roll:
 
OK, I have found a source for 5mm pitch GT pulleys in 102-143 tooth arrangement. It's kinda pricey, and he is just cutting from pulley stock, so you will at the very least have to drill a hole. But he can also machine anything for a price. Is Napersville, Ill. near you Matt?

Check out his outboard bearing enclosure on that super Kart, that is some trick shiot! 8)

What's kinda pricey?

He seems to be a ContiTech agent.

Worth bearing in mind that Conti have a greater range of belt lengths in 5M pitch than Gates.

Conti belts are HTD tooth form, not GT (though there's not much difference).

Yup, Nperville is 60 minutes south of me. :D

Hi,

Great work.

How about merging this thread into the existing one titled "Resources" ?
Click to expand...

Or making it a sticky (please).

Also (anyone) feel free to add sources for #25 and #219 sprockets.
 
Hey Miles,
Feel free to move this thread to the resources area, obviously it should have started its existence there. I don't know what the little bastard is doing out here with the "normal" threads. :wink:
 
Hi Etard,

I'm trying to keep the Resources thread as compact as possible, in order to make it easier to actually get at the info. I think it's better to keep it as a series of links. I've posted a link to this thread there, but if you want to repost all the links from this thread, that would also be great.
 
found another place for drive components... and robots :D http://www.robotcombat.com/store.html
 
Found this good supplier in the UK:

https://www.powertransmissiononline.co.uk/ :)
 
another good resource http://www.hpcgears.com/

no min. order, based in UK, but deliver anywhere.
 
I have been researching pulleys and toothed-belts recently (sometimes referred to as "timing pulleys/belts"), and I want to share the results.

A common method of shaft attachment is to purchase a metal pulley with a shoulder that has a threaded hole for a set-screw, which would press against a flat spot that had been ground into the side of a shaft. Changing pulley tooth-counts in the future was expensive, and attaching a pulley to a motor shaft sometimes involved buying a pulley with a smaller hole, and drilling it out to the motor-shaft bore, taking care to make the new hole as concentric as possible.

Recently there have been some very successful builds using a 5mm-HTD pulley and belt. 5mm is the distance between the peak of one tooth and the next (the pitch). There are several different common tooth shapes, HTD works well for electric-bike builds. Ensure that all of the pulleys and belts ordered have the same pitch and tooth-profile.

The belts and pulleys come in several widths. When ordering, take care to ensure the belt width is the same width (or narrower) than the pulley track. 15mm (0.6") wide is common.

SDP-SI sells the "Shaft-loc" coupler. It is an expanding compression-bushing that connects a smooth-bore pulley to a smooth round shaft. The Shaft-loc is one of several ways to connect one family of pulleys to various shaft diameters.

Shaft-loc pulleys are cast plastic, with a metal center. The ones I am interested in have a 3/4" (0.750") smooth bore. There are parts available to attach these to an 8mm, 10mm, 12mm, or 1/2" shaft.

There is a wider choice of pulley tooth-counts available if you only need a flange (guide-plate) on one side of the pulley (rather than 2, one on each side). The Gates pulley tutorial stated that if one of the pulleys has only one flange, then the belt is easily loosened for changing with a tiny shaft-mount adjustment, rather than the motor or jack-shaft needing to be moved a lot. Also, it is common to have one pulley with a single flange on one side, and the other pulley also having a single flange, but its flange is mounted opposite of the first one.

If using the Shaft-loc system, you can add a wide washer/disc on one side to create a second flange if desired. There is a 19 different tooth-count range of 5mm-HTD Shaft-loc pulleys with a metal 0.750" dia bore. (20T, 22T, 24T, 28T, etc)

20-tooth, 1.25" diameter, $16 (plus tax and shipping)
80-tooth, 5.00" diameter, $23

$23...Shaft-loc 0.500"ID-0.750"OD compression-bushing
$6...0.500" OD-to-Metric ID "bore reducer" sleeve for attaching to an 8mm, 10mm, or 12m shaft

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Case-hardened 1/2" diameter shafts (12" long or shorter, pre-cut to size in one-inch increments) are available from McMaster-Carr for less than $7 each (plus tax & shipping).
