I have a question about friction in these one-way roller and and one-way sprag type clutches. There doesn't seem to be much rolling going on. This appears to be because the rollers/sprags are static (non-rolling), unlike in a regular bearing, where they roll along both the inner and outer race. So are these (both roller and sprag type) one-way clutches just very high friction? Thank you for any answer. I greatly appreciate it. Cheers mate!
i would like to know this as well! Compared to a normal bearing (of the same size) how much harder is it to rotate this One-Way Roller Clutch? Its a shame that after a year no one has answered this :(
ok so even though its been a long time since this comment was posted i will answer the question for future visitors. I just bought a few one-way bearings and tested them. The ones i got are smaller than the one in the vid but the mechanism is the same. They are not high friction at all, they roll just as easily and smoothly as their normal bearing counterparts (of the same size).
Lets say the outer race of this clutch is attached to a rotating piece, a wheel for example. And the inner race is being driven by a motor shaft. If the wheel spins faster than the motor (say the wheel is rolling downhill for instance), will the centrifugal force cause the rollers to disengage from the outer race assuming the centrifugal force is stronger than the resistance applied by the accordion springs? Thank you in advance!
I don't get it. Are the rollers moving tangentially to the inner race or just spinning in place? If they are moving then why wouldn't they move past the wide part and jam on the back side of it where it narrows down? Or do they go from moving laterally to spinning in place once in the wider part, and stop moving laterally and just spin?
@Swim Fan I don't understand does this croller clutch disable that small gear can rotate only in one direction? Or roller clutch prevent that engine when get started doesn't spin starter in high RPM?
Why rollers don't start rotation on their own center under lubrication when turning to wedged side like running on log in water in cartoons? Sorry for bad reference
Do you see those little ridges or grooves inside the inner ring of this beautiful bearing? Those are called the "inner spline". They will mesh with the external spline of a mating shaft for the purpose of transferring torque. This arrangement will preclude your "running on a spinning log just before the waterfall" situation...
Thank you, for taking the time to explain this.
Excellent explanation
why dont the inner race just slide without rotating the middle rollers ? genuine question , plz answer
Similar logic is used in security tags in stores👍👍
Great explanation. Thank you!

So I'm either super confused or there are balls in there that we can't see and they're slightly touching the rollers as they move
@@tay5901 i believe that particular bearing uses cylinders instead of balls, has the same effect.

What about maintenance? Do they need oil to extend lifetime, or will they stop working with less friction?

That is all correct 👍
thanks ma bro have a good one
Excellent stuff!
What are the features and benefits of one-way clutch?
It can allow torque to be applied in one direction, and when torque stops being applied, the rotating member continues to move freely.
1:11 lmao you said "counter clock ways". that's a first for me.
Interesting, well explained...
Great explanation thank you
What is the model of clutch you are demonstrating with?
just iwant another type please?

Can you explain what is function of this roller clutch in car starter?
