Ratchet gear standard profiles

Ratchet gear standard profiles

Ratchet gear standard profiles

(OP)
I would like to know if anyone can point me in the right direction. I am looking for a or website that will have some data on standard tooth profiles for ratchet gears of varying types. I know that my machinist handbook has standard gear profile information but nothing on ratchet profiles.

RE: Ratchet gear standard profiles

Gears are standardized.
Ratchets are not.

You can buy ratchet/pawl pairs, but the vendors may be reluctant to reveal enough geometry to let you make your own or use another supplier.

You could roll your own. ... but it would be worth buying one of those 'how to design everything' books so you have someone else to bitch at when it doesn't work.

If you decide not to use someone else's proven design, don't put much money in tooling until you have worked the bugs out of yours. Fail early, fail fast.

Thank you Mike for letting me know that there are no standard designs for ratchets.

Do you Mike or anyone else know of specific manufacturer or suppliers who sell a variety of ratchets. I already have a few from McMaster but I would like something smaller than what they carry. I know that Pic Deisngs and Standard drive products has some off the shelf ratchet assemblies, but they are pretty basic and have very few options.
