Custom Clutch Gear

[nxtstep101]

I was recently playing around with gears, and geartrains and came up with a simple yet effective way to make a custom clutch gear:

I was really pleased with its effectiveness, and simplicity.

Note: The more you gear it down, the harder it is to stop it.

Enjoy!

I have always been confused what a clutch gear is used for...is it not just a diff?

Here is a TechnicBrick's post about the clutch gear: http://www.technicbr...nic-clutch.html It will explain how it works in more detail then

I could.

Thank you! So a clutch gear is just really a torque limitation, right? but...I really like your design!

[nxtstep101]

Yes, that is basically all it is. Thanks!

That really doesn't seem like it would be effective or have much use since it has very very little friction other than the bushings holding it which probably wouldn't last very long.

[nxtstep101]

It may not seem effective but it really is, It gains a lot more friction when you gear it down (as I did in the video). The bushings actually will not wear out fast since there is barely any pressure on them.

Sorry, but its not a good idea. Bushings will in time due to vibrations and forces spread apart, just look at motorized models, where the unsecured axles tend to slide sideways out of gears.

This is definitely true. I can imagine using a spring from a shock absorber pushing the against gears to generate some friction. But as a serious solution it still somehow not durable enough.

Any part, in time will break! And the bushings don't really vibrate at all. I have been using it for quite awhile and have had not problems yet.

True a shock absorber would also work, I would try it but I don't have any yet.

What exactly are you using it for?

Read post 2 and 3.

Yeah and.....? I know what a clutch gear is. But where in either one of those posts does it specify what this clutch mechanism is being used for? It obviously cannot be used to drive a vehicle or be used under much torque.

Maybe a small machine, such as a walker?

Nice job, but it looks a little weak. I built a clutch that used pneumatics to variable adjust the resistence, it could hold up to a lot.
