belt pully crowning
(OP)
Im building a drive system with sync. belting and I'm looking for some info about tracking. I know that a belt will try to find center on a crowned wheel but does it have to be radiused or can it just have a taper.





RE: belt pully crowning
Some of our timing belts (mounted on shafts with real good alignment) have had a noticeable tendency to "track" one way or another, and flipping the belt reduced or even reversed the tendency to track. I think the manufacturer's catalog mentioned flipping as sometimes necessary to correct tracking issues
Flat belt pulleys are often crowned a little for good tracking (specs in machinery handbook, among others) but I'm not sure timing belts, which tug on the pulley major diameter, would like
RE: belt pully crowning
I have a flanged drive pully but the two tention wheel are smooth and run on the back of the belt. the arrangement is for a linier drive with the belt stationary and the drive moving along it's length. I'm having trouble keeping the belt centered and tracking straight. I presently have guides on either edge of the belt to keep it in line. this is working well, but I'm concerned about wear to the belt edge over time and would like to find a more precise method. the tention wheels are turned from 120mm 6061 and are 40mm wide. I can place a slight taper to crown them but I don't have the tooling to radius them. I was wondering if anyone knew if this would work.
