"A" Belt timing pulleys?
« on: June 07, 2009, 07:11:36 PM »
I've found a great place in California for treads for larger scale robots: California Industrial Rubber! :D They gave me a low price quote and they have some really good stuff! They do robot treads and even did treads for a profession Wall-E robot, they've told me.

One question though with the quote they gave me: They said to guide the treads on my robot they use an "A" belt attached on the inside of the treads. The "A" belt they showed me on the inside of the treads has notches in it, which I assume go with timing pulleys. The problem is, I can't find any timing pulleys with "cogs" to pull the "A" belt.

Do these kinds of pulleys exist? Did I misunderstand the quote? The "A" belt did have notches in it, but...no timing pulleys for "A" belt to go with notches... ???
I think the chauffeur did it.

sounds similar to a standard belt those notches are probably just to allow it to flex around the pullys without causeing stress in the belt a lot of belts have them that don't have cogs in the pullys

Thanks madchimp. I went back to California Industrial Rubber and they said that's what the notches were for. They're going to give me a new quote tomorrow, this time with a timing belt down the middle of the rubber treads and two V-belts on the sides for guiding. :)

Thanks again.
