Re: Timing belt in drive success

This fall our team is looking into designing a few custom chassis utilizing newfound resources and skills our team as acquired. One of the areas I have been looking into is WCDs and more recently I am looking into using belts instead of chains.

My question for teams who use belts is: how do you attach the pulleys live axles? Do you hex, key, or use set screws ( )?

Additionally, is there a healthy range of movement for your bearing blocks when using belts? I understand chain stretches overtime and I heard pulley aren't known to stretch but do you leave extra room to make taking belts on and off easier?

Sorry for all of the questions, our team is small and young but we are trying to absorb as much as possible!

Thank you!

BrendanB
