I've been tasked with spec'ing out an automatic winder for large-ish stators(~2.5 ft dia) for 2 AC generators. I'm putting a contact list together to start, but I'm unfamiliar with manufacturers that make these. Do you have any suggestions on whom I should contact when looking for quotes?
Thanks!
Being rather fresh to the ME workforce, I recently applied for membership with ASME for career development and possible mentoring. I wanted to toss out a few questions in the spirit of making the most of the experience:
[tab]What have you found most valuable about ASME (or any professional...
It is a large, ~3" nut that holds a rotor on a shaft of an aircraft generator. It is magnetic, HRc = 28, and has a spark consistent with a low carbon steel. I would assume it's a simple 1000 series steel alloy, but since it is going on an aircraft I do not want to assume anything :P.
We do...
Recently, I have run into a GE print (ca 1962) of a part that we need to have made. It lists several options for material, but under a General Electric material specification (B5F15B and B5F7H2 to be exact). Has anyone had any experience with this specification? It seems like an internal...
WL/4Z is derived from Mc/I...
The section modulus is defined as Z = I/c
Also, (for a beam of length L, simply supported on each end with a load, W, applied at the center) the maximum moment is
M = WL/4 (at dist = L/2)
If we insert these into your standard Mc/I equation, this leads to the...
I've been searching for possible thrust bearing solutions to be used in a steel media blast bay. This place just eats bearings for lunch. Is there a thrust bearing that can hold up in this environment?
Magnetic bearings? (I assume that steel blast media may interfere with these, but I've...
CURIOUSMECHANICAL,
METENGR is right about ASM. I actually have the ASM Handbook, Vol. 1, "Properties and Selection: Irons, Steels, and High-Performance Alloys" sitting in front of me. It has about 150 pgs. of hardenability data for carbon and low-alloy steels. It contains material selection...
I would have to say no. The inch unit in torque refers to the distance that the tangent force is from the rotation axis.

The definition that you have sounds closer to a work equation, which is force through a distance, but using the word 'torque' in place...
winpop123,
ASME Standard "B18.2.8 - 1999 Clearance Holes for Bolts Screws and Studs" may have what you need. This covers "close", "normal", and "loose fit" holes for bolt sizes from #0 to 1.5" and M1.6 to M100.
As for the chart relating the positional tolerance, you could do a simple...
If I understand you correctly, you are wanting to know about annular snap-fit joints. There was a great article in the January '05 issue of Machine Design.

I know that in other drawing packages there are ways to create custom symbols and add them to the general library. Is this possible in SW? If so, how? If not, what is/are the best option/s to insert a custom symbol into a text field?
Currently, I have simply sketched the symbol and must...
Thanks for getting back so quickly...
I'll take a step back... I am trying to create overlay templates for inspection of these complex parts on an optical comparitor. There are some profile callouts on the print that reqire me to offset them X amount, bilaterally, creating the visual boundary...
I am fighting SolidWorks to create boundaries of the profiles of complex parts within a .SLDDRW file.
I have been semi-successful in being able to hide tangent edges and select SOME profile edges, which are then bilaterally offset to make the profile boundary. Unfortunately, there are some...
I just was searching for a solution for this in SW 2005. Just as an update to this thread... You can apply a cosmetic knurl by...
modifying surface texture --> metals --> machined -->knurl1 or knurl2
hope this helps down the road.
