Re: leadscrew bearings / machine design

Sorry about the size. I was concentrating on the issue at hand, and
should have thought about zipping the file. That reduced the size by
98% to less than 80k. The .bmp is the only generally readable format
that Autocad2000 supports. Tried to read the .bmp into Photoshop5.5,
and of course, it wouldn't read a .bmp. Appologies to all, and
thanks to those that helped massage it into a readable format.

As for the dwgs: It shows two different configurations for a FIXED
or RIGID lead screw installation. Showing only the end away from the
motor. These are my intrepretation of a textual description of what
is supposed to be common industry practice. Any and all comments are
welcome. I'm simply trying to figure out how to do it on my machine,
and assume that the dwgs probably do not exactly represent what the
original authors intended.

If I have drawn the bearings incorrectly, DOH! Each stackup is
intended to show two bearings (in keeping with RIGID and FIXED
definitions). Both the internal and external races are shown.

TIA, ron
