Gates Corporation is offering free belt drive components to FIRST robotics teams during the 2011 FRC preseason. Visit **www.gates.com/drivedesign **to view catalogs, drive design manuals, and drive design tools, then fill out this form and email it to [email protected], with your team name, number and the word “FIRST” in the email subject heading. Parts will be ground shipped to the address you provide in the form free of charge. Gates does reserve the right to limit the style and quantity of parts provided to each team. If you have any questions or concerns, please call Gates Product Application Engineering at 303-744-5800 and select Option 2.
We ordered parts from Gates for our prototype this offseason. I’m not sure if there is a set limit for cost or quantity, but they reserve the right to not give you parts. We were given every item that we requested which included about 16 pulleys and 3 belts. My advice would just be to keep your orders within reason and not abuse the offer.
Gates will be honoring pre-season 2011 FRC orders up through December 15, 2010.
If you are stumped as to what parts to order, keep in mind Gates supplied **5mm PowerGrip GT2 **belts and sprockets for the 2010 FRC. These components should work very well for the FRC 'bots, but the sprockets are made out of steel. If you want to use aluminum sprockets, (with lower load ratings than GT2) you should use 5mm PowerGrip HTD belts and sprockets. You can download drive design manuals at Design Power™ to determine part #s.
Fill out the attached form with your desired part #'s, and then email to [email protected].
I ordered the 5mm HTD belts and aluminum sprockets. I was expecting to get sprockets that had the rims on them as the picture in the catalog showed. Instead, I received ones with no rims. I went through the catalog again to make sure I ordered the proper part number and did not see any mention of rim vs. rimless options. Did anyone else have a similar experience?
If you were able to get the ones with rims, please let me know how you did it.
Hi Raul; I hunted through the catalogs and I agree it is pretty confusing. It appears to me that the HTD belts do not come with a flange; If you look at the figures for the GT2 sprockets they call out a type “A” on the top of the picture for unflanged and type “AF” on the bottom of the picture where the flange is shown. In the HTD picture it shows the same flange on the bottom but doesn’t call out a different type; in the type columns for the HTD sprockets I don’t see any types with an “F” suffix.
Please let us know what you hear from Gates. I would love to use the belting donation this season, and would prefer to use the HTD profile (better interoperability with other manufacturers’ parts) over the proprietary GT2 profile - but if Gates doesn’t produce (aluminum) HTD pulleys with flanges, I will need to find another plan. I don’t trust a non-flanged pulley for many/any uses in FRC.
OK, I exchanged some emails with the Gates rep. He said that for Aluminum HTD sprockets with 5mm pitch and belt width of 9mm or 15mm, any sprocket with up to 34 teeth will come with flanges and any sprocket with more than 34 teeth with come without flanges. These are the only options.
