I met two guys in UK who are young mechanical engineers using a networking app called SHAPR.

I’ve just asked both of them via email if either of them could run a motion study on the design.

Here's where the number 8 arm would appear to first fall. You may need to make a clearance at the end of the arm nearest the center to clear arm 7. Also if arm 8 slides down, it may not turn at all if it hits the red retaining pin. The other issue might be that at this point in the rotation, most of the mass is on the left and may slow or stop the rotation?

I’ve not drawn it yet but how about each arm has the fulcrum that is in front of its path as part of the arm.

So basically like a guide roller being part of the arm as the fulcrum.

[soundiceuk]

I’ve just come up with a new design that makes the pivot the fulcrum at the same time and it works both ways.

The slot in the arm is rectangular but opens out at end furthest from axle to allow rotation.

I’ll have to draw when I have time to explain.

i'm starting to learn spaceclaim, the good part is that it has a physics simulator and seems quite easy to use overall.

I'll be able to transform some of these ideas into computer simulations.

The bad part is that i think i'll be in hospital for several days, i might go through a surgical procedure, minor. Hopefully everything will go well and i'll recover fast but still have other health issues.

Here is a picture to convey the new design feature which replaces the fulcrums with a new arm slot that works as a fulcrum, guide and pivot.

Working on the basis of 10mm slot.



There may be a better way to do this but for now this is what I've come up with.

Luck forward to seeing any simulations.

A great tool for tuning I'm sure!

Good luck with your ongoing health issues

Modified arm and pivot design to allow arm to be fulcrum.

Hahaha, I've drawn it backwards..... I will correct

[soundiceuk]

The corrected drawing.

Thanks to your input, here are some images of the new design.

Straight up noon

Hi,

What causes the swinging arm to become vertical at 12:00?

The center of gravity is moved far away from the center of the axle.

The wheel acts like constantly tipping, balance scales

The previous arms hit each other and lever the arm until gravity takes over and the arm falls down the slot and onto the square peg.


The mass of the wheel stores enough energy from the decending pendulum/levers to ensure the wheel turns fast enough to bring the next pendulum into play.

There is constantly more weight on one side of the wheel. It seeks equilibrium but never finds it.

Hopefully this explains it better!
