Gearing Up- Bevel Gears

@ZooHead, I came across this video today...

@ZooHead, I came across this video today...

I've been following this guy ( Wintergatan ) for years. He has built a couple of versions of this device and video blogged each step - the latest version ( Marble Machine X ) using far less wood. Basically, he draws the parts he needs in various CAD applications and people from around the world have volunteered to machine them for him. It's programmed using peg boards/wheels, the same way looms were programmed a century ago.

@jdmac, Thanks for the video. like @MonkeyT, I have watched some of his later work.
Really fascinating machines.

 

[ZooHead]

Here's the latest version.
Soon I'll have to put in some screw heads.

 

[jdmac]

@ZooHead , is the punch-out pattern on 2 side panels part of the object (model) or a transparent section of the material?

 

[ZooHead]

@jdmac It's a PBR material with image based transparency.

@jdmac It's a PBR material with image based transparency.

I thought it is the case.
Thanks.

 

[ZooHead]

My plan is to replace the ZOOHEAD letters with a dot matrix style LED sign.

I used a time based material to animate a gradient for the "flicker" effect.
Here's my first test:

I found a little glitch in the current design.

That'll need more than a little extra grease.

I just had to reduce the size of all three gears.

This is the power output socket.

Now I'm just going over all the mounting plates and making a few changes to simplify the design.
Still waiting to add screw heads.

Although this isn't a bevel gear, it's part of a separate drive
system which will be under the Modular Motion Blocks.

I needed something which will produce high torque so the worm gear seemed to be a good choice.

Unlike standard straight cut gears, usually called a spur gears,
a worm gear produces thrust forces along the axis of both gears.

The thrust force is greatest on the worm gear, but because it's companion
gear is cut at a slight angle, it will experience some thrust force as well.

Fantastic stuff!

@ModellingGuy Thanks

I just finished placing 36 screw heads, using the particle mesh method.

Awesome!

 

[ZooHead]

I had to redesign the upper gear set a little for a number of reasons.
Now it's a little less cluttered.

 

[ZooHead]

I'm getting pretty close to finishing. I've gone over everything and either eliminated
all Booleans or made them editable. Booleans really tax the cpu so this is quite helpful.

Now I can work on the look of the "packaging".

 

[Charless]

Is there a spring of some sort to power the device? (did I miss it?) or a LIPO battery, solarpower

 

[ZooHead]

@Charless Power comes from underneath.
That was the post about the worm gear drive.
I still have to build it.
