BP Machine MMC Nov-Dec 2011

Post by Finis » 14 Nov 2011, 04:39

To make gears I started with a cylinder. Then I selected some of the faces around the edge in point edit mode and used point edit scale to move them in or out. That made the teeth. The detail on the sides is from moving some faces and using bevel in point edit.

oh ya, i forgot, i should mention the plugin named Gear Generator - geargen :) Maybe that can speed things up. but its not too complicated to make gear anyway.

So far very nice start, we need more gears! :)

I'm not sure if I found the geargen you wrote about Bitkar. I found a geargen plugin for Rhino and this http://woodgears.ca/gear_cutting/template.html" onclick="window.open(this.href);return false;. I made a few screen grabs from the online one. The download demo makes distorted images and dxf files. The paid version looks good if you make money from 3D gears or just can afford it as a toy.

I'll model a few gears with radial arrays of teeth and various inner wheels or discs. Here is a gear with spokes and a prototype machine. The prototype helped with overall style, spacing, and sizing of components. It also revealed some mechanical flaws.

This will get steampunk details and textures.

Those are amazing gears. Is the second gear made by hand? Or did the Rhino plugin also do that one?

Thanks Draise. All of these gears are hand made. I don't have Rhino so I didn't get the plugin.

I made the orange gear using the reference image shown. The image is a screen grab from the online gear thing at the link above. I made a tooth and then a radial array of teeth. Then I point edited a cylinder for the beveled inner disc. Then I made a shape to cut the spaces between spokes, radial arrayed it, and Booleaned it from the disc. That way I can make several disc designs and put the same teeth on them. I'll do that for a few more gears.

The earlier gears are from cylinders with point editing to push, pull, and bevel faces.

The prototype machine had too many gears and couldn't have functioned. Its bars connecting the discs on the ends would hit each other or the axles. Next is a new prototype with those corrected. The final might get chain drives instead of discs and bars.

Thanks Bitkar. I'll try the plugin. Where did you get it? If I can make many different types of gears with it then I might use many different ones.

Here is an improved prototype machine and a massive one made with copies. The regular one is the one for the project.

Geargen crashed TS 7.6 and TS 5. A warning said it was for TS 4 so I guess this plugin meant it.

Here are Gears 1A, 1B, and 2A.

Then do.

These are probably the teeth for the gears. Each gear is a group with teeth and a disk. I'll make a few different disks/spokes and mix them with the teeth rings for variety. One gear has a bump map border. I'll apply bumps for style.
