Great to see someone who knows the difference between a sprag and a roller clutch. The amount of people(specifically some "experts") that think the term "sprag" is a generic term for all oneway clutches is staggering.
a hundred and ninety one up-votes...?? twenty-six comments........? the RUclips algo is acting like a pal against your efforts & is shafting you guys. This is _amazing quality:_ Good explanations, demonstrations and gradually builds up my understanding (for free). Great pedagogy. Truly; THANK you.
Also there is a mechanical diode and the rocker style one way clutch where the plates are not serviced seperately as in the 08-10 ford 5r110w low one way,,reverse planet assy
Nice Information, could you please explain the uses means where it is applicable of sprag clutch and roller clutch? Also, what are the other similar components to these one-way clutch?
Want to ask a question. Seem confusion the rotation which way.thinking I want to mount a smaller tires as a fly wheel that free spinding as the car stop.. does this do it? Want to charge my battery somehow. So it all motor bike has a auto clutch bearing?
Great Video! I have a 2004 Honda Odyssey with a bad one way clutch (sprag style) in its automatic transmission. When coming to a stop it sometimes doesn’t engage but I can get it going with putting the gear in low or 2nd manually. I’ve been driving like this for 1 month. How long do you think this one way clutch failure can last ? Will it get worse and ultimately fail ?
Yeah, those 5-speed sprags wear into the inner race, then sometimes don’t grab. When you put it in low range, you are applying a low clutch that helps prevent the sprag from freewheeling. The clutch doesn’t have as many frictions, so it cannot hold a ton of engine torque, but if you don’t accelerate too hard, it’ll probably work like that forever.
A sprag clutch is more power dense than a roller-ramp type. Then, in general, a sprag cluch prefers the inner race to be the higher speed free-wheeling member. A roller-ramp prefers the outer race as the freewheeling member. There are exceptions as always. A sprag clutch will definately freewheel at higher rpm.
My u140f 4-speed automatic transmission is unable to shift into 4th gear, and I can figure out on my own what is causing that problem, but what is puzzling to me is that, apparently as a side-effect of that problem, I am now able to use my O/D button to engage/disengage engine braking. In other words, instead of the O/D button controlling whether or not the transmission is allowed to shift into 4th gear or not, now the O/D button instead controls engine braking. Anybody know how that might be possible?
Thank for the Video. Very Useful content. I understand this is used as One-way Clutch. Do you have something where clutch can be used for bi-directional rotation. I mean allows input torque transmission to output in both Cw and CCW direction but it stops transmitting from Output to Input. Basically to prevent Backdriving of Prime mover due to exteranl load on Output side?
I guess im asking the wrong place but does someone know a method to log back into an instagram account?? I was stupid forgot my password. I would appreciate any tricks you can give me
@Luke Beckham Thanks for your reply. I found the site on google and Im in the hacking process atm. I see it takes a while so I will reply here later when my account password hopefully is recovered.
If you check the auto trans playlist, you'll see more videos on basics and some in-depth videos on certain units. I cover the powerflow, hydraulics, and electronics on many transmissions.
@@siuautomotive could you do more videos about that trans or link some more videos about it. I’m trying to learn about it and ask companies to build a stronger transmission.
Many years ago I worked for a company that designed and manufactured turnstiles, the kind you might find in railway stations and football grounds. A new model turnstile was designed for a specific customer. In place of the traditional pawl-and-rachet the new design used a one-way bearing. Instead of the usual click-click sound this one was totally silent and could not be turned in the no-go direction, not even by the smallest degree. In applications where a mechanical device is used by thousands of people every day, even the remotest possibility of an accident is likely to become evident sooner or later. This became sadly true and resulted in the death of a child. Mechanical engineers, please be warned. The old pawl-and-rachet seems intrinsically safe. After each click, the turnstile can be rotated backwards by a small amount and provides a margin of safety under extreme conditions of use.

i was stuck with my homework, and you rescued my knowledge,
thank you sir!
Also there is a mechanical diode and the rocker style one way clutch where the plates are not serviced seperately as in the 08-10 ford 5r110w low one way,,reverse planet assy
Good explanation.thanks

Dear Sir, it is really a very nice explanation...I need an one way clutch along with sun gear...I don't know how can I get it from the market

what component that prevent planetary carrier from rotating in two direction of rotation?. in KF4A222 transaxle
Any disadvantages or limitations,such as power reduction etc

@Luke Beckham it worked and I finally got access to my account again. Im so happy!
Thank you so much, you saved my account !
@Reign Ray you are welcome :D
can you to power flow with charts like on and off solenoids

6F50 as in the 6f55? From ford
Yes, the same design. The 55 handles a little more torque.

Thanks for sharing. I can see how that sprag design could cause problems in a turnstile.
How did it kill a kid?
