Geared vs. Gearless Ratcheting Mechanism

[dede2897234]

After reviewing the thread on Toptul's gearless ratchet by "Auto-x fil", I was wondering what makes a gearless socket ratchet stronger than a geared ratchet? How does a gearless socket ratchet work?

Thanks,

Dave

Notice there are four relatively large rollers in the gearless, versus one or two relatively small pawls in most of the geared.

thnx, jack vines

A gearless ratchet reminds me of those new constant variable ratio transmissions - I don't think I could get used to either one.

I've worked with linear bearings that looked similar, but they would only turn one way. Not sure exactly how they worked, but they were installed on packaging machines that operated thousands of cycles a day. The bearings would fail about once a year.

yeah.. Chrysler already use it on compass as CVT transmission.. it is very interest for me to work on it but problem is other tech cant disassembly the transmission so he said transmission need to be replacement... so warranty was covered...

I would not draw that conclusion from such a simple test.

It's possible that a gearless ratchet is stronger - the camming action forces the rollers out against the housing, so the weak link is probably the housing cracking. On a geared ratchet the pawls can shear off, which may be weaker.

I don't read many stories of people breaking ratchets on this board. I've broken a Craftsman (huge breaker bar on a 3/8"), and I've broken a few super-cheap Chinese ones. But a quality ratchet, being used appropriately? I don't think overall strength is really a limiting factor.

Are these like one way roller bearings that are used in fishing reels? Like Shimano's "Supper Stopper" bearing?

Who makes a good one of these socket wrenches?

I have a Britool 3/8 gearless ratchet that was my go to ratchet for many years. I found it to be both very strong and smooth in action. The only drawbacks were that the head is quite bulky and therefore too big for tight clearance jobs. The other thing is that it doesn't have a reverse lever, and instead uses a push through square drive, although that never really bothered me.

Do they still make such a wrench?

Any idea on where to purchase one?

I think they are still made, but not by Britool per say. I believe they are now made by Rotar in Taiwan and then stamped Britool.
If you are after an original Britool ratchet you could try www.trademarquetools.co.uk , as i think they bought most of the old Britool stuff when production was moved oversees. The part number for the 3/8 version is MRC 200P. Hope this helps Jon

I have had mine for a couple years and no problems at all, the heads are big and these do reverse.
