How does it produce this energy? You haven't specified a source of work. |
|
| |
The objective of most engines is to translate linear or reciprocating motion into rotational motion. |
|
| |
Is this an idea, or a "Lookee here, at this cool thang I done foun' on th'innernet, Earl, Hyuk !" |
|
| |
You invented the Sphericon? |
|
| |
JesusHChrist, that wouldn't have a prayer. |
|
| |
Ms Christ, or may I call you Hellen?, I see from the links that sphericons roll in a straight line, but 'wobble'. When they roll against another sphericon, is the point of contact one dimensional or two? |
|
| |
Also, in your design, what holds the four sphericons in place - what is working against them? I'm tempted to bun this just for leading to the links. |
|
| |
Are you not simply using the sphericon as a swash-plate motor? If so, why? |
|
| |
Apologies, I got the idea confused with the second link. However, if your single sphericon is fixed, then the sharp edge traverses your contact bearings on each turn - this would lead to failure of the components pretty quickly. Better to have the contact bearings traverse the curved portion only (you could choose a path that varied the distance from the centre - introducing reciprocal motion) perhaps by use of some kind of elbowed rotating rod which would introduce a 'wobble motion', rather than a straight through one ? |
|
| |
We get that bit. The problem, as I see it, is the area of the contact surface. It's basically two dimensional, placing extreme load on that line. As [CF] points out, that sort of thing leads quickly to mechanical failure. |
|
| |
It was a major problem with early rotary engines (Wankel), that they started spewing oilsmoke as soon as there was any appreciable wear on the rotor seals. |
|
| |
I still don't see a purpose to this idea, either? If it's simply about translation of motion then I'll stick to a gearbox and differential. Elliptical gears do it quite well. |
|
| |
You might find an application in the "hip" joints of robotic quadrupeds, I'm guessing. |
|
| |
I don't even fully get what shape a sphericon is. I've read and re-read mathworld's description but it's not seeping in. I need to hold one in my hands, I think. |

Bristolz - to get the shape of the sphericon,
1. Go to the first link, JHC's website
2. Find the photo of the sphericon with the caption "a beautiful wood sphericon from someone else's website"
3. When you look at the photo, keep in mind that the back (hidden) side of the wooden sphericon looks exactly like the front (visible) side. Imagining that back-front symmetry should help. |

Thanks [robinism], I have finally understood the shape! |

[Bristolz] the fourth link will do the trick. |

is there a hamster inside that thing? |
