So why don't we see the roll waves in artificial wave surfing facility's?
As you can see from the inlet on the top all the way down to the bottom of the valley of the wave the water is almost completely flat, and it is a pretty thick watersheet over the floor of the artificial wave:
And you can...
My application is not really a waterslide. That was just used as a example. My real application is in surfing and the depth is to accommodate some fins on the board so they dont just slide on the bottom plate, but actually function like they do in the open water.
How can i calculate the waterflow to maintain X level flowing down a flat inclined plane?
For example say you have a waterslide that is 1 meter wide with a incline of 30 degrees and want a sheet of water 10 cm deep flowing down the slide. How many m3/h of waterflow do i need to supply on the...
Yes as I say in the opening post I only need it to disengage when it is unloaded. Because the bike is standing still when i am going to roll it back to get it out of my basement or off the transport i'm on.
That would take up even more space than adding a additional clutch to disengage the...
My goal is to make my DIY ebike be able to roll backwards freely when the motor is not powered. On most crank / middrive ebikes there is a sprag clutch between the motor drive and the crank so one does not cause drag for the other. But this causes the motor to drag when trying to roll the bike...
All types of sprag overrunning clutches have some sort of spring to keep the rollers or sprags in contact with the running surfaces so they can engage and wedge to lock the two surfaces together when turning in the locking direction. But is there any kind of sprag clutch where you can...
The circular grove is what i mean when i say "collar" The front taper is there to give the collet support in front of the "circular groove" so you can for example clamp tools that is not sticking verry far into the collet.
As i said if you push the collet from the rear to release it there is no...
The reason for the front taper is because of the collar so you are able to pull the collet out from the front because the ER collets has a semi locking taper that needs to be pullet out with force to release. If it had been pushed in from the front, and pushed out from the back it would not need...
No it does not. A continuous OD taper along the whole clamping length works just fine to uniformly compress the collet. As demonstrated by morse taper collets. And it works even better like the design in the opening post shows pushing it into the taper rather than pulling it because then the...
That is what i was writing about the third style of collet. But this flexing to become parallell does require the part that is being held is supporting the ID the whole length of the gripping section of the collet. While a ER style collet will remain mostly parallell even if it is only supported...
The problem is that you have to close the slots in order for the collet to not be 3 separate pieces. So if you close the 3 slots in one end, and keep them open in the other the collet will just be able to clamp on the end with the open slots, and with a simple taper along the whole OD of the...
If you want to finish the ID before slitting it you would have to make an expanding lapping / grinding arbor, while if you slit it first you can use a fixed size lapping hex and use the collet to tighten it as you grind away material. So slitting it before finishing the ID seams like the...
