Paul,

I'm starting to model a rotary in my spare time, and I am in need of
some accurate dimensions for the 13B and/or RENESIS engine. I've
drawn the trochoidal housing and rotor shapes from Yamamoto's
equations and numbers published in his book, but I don't have an
example around that I can measure for the other dimensions.

What I need mostly at this point are critical dimensions like rotor
housing depth, center housing depth, thickness of the rotor housing
wear surfaces, locations/spacing of the tension bolt holes, major
e-shaft dimensions, stationary gear height and diameters, and so
on...

My purpose is to design new housings and possibly rotors that can be
used with the mazda e-shaft, gears, bearings, etc.


I've seen pictures of your models... are they detailed to this
level, or are they mostly just for mock up?

I have a iges of a rotor housing. Can your email handle a zip file?

Paul Lamar




Yes, zip is just fine.

Josh


Here it is.

Hey Paul,

If you rename the zip file thus:

rotor_housing2-igs.zip
rotor_housing2-igs.piz

it will not be filtered out by email agents that filter out zip files.
When your correspondent receives the file all they need to do is rename
the file from piz to zip again.

Windows is too stupid to know that the file is a zip file if you change
the file extension.  Just make sure that you explain what you've done to
your recipients so they know they have to rename the file.
