part feature vocabulary 4

[TerryR1]

Has anyone come across a list of words to describe part features? I'm making some pretty complicated parts and have run out of words to describe them and their features.

Some examples of what I'm looking for:
gusset
pilot
countersink
race
flange
lobe

Specifically - what is a good word for the a turned protrusion on a shaft (think opposite of a groove)?

Thanks!

Hi TerryR1

protrusion on a shaft:- stub diameter, step diameter,stub.

desertfox

Hi TerryR1

Thought of another:- spigot

turned protrusion, opposite of a groove: shoulder, collar

Yeh it is something between a shoulder and a collar haha... I'll use collar thanks Ted!

Has anyone see a list of these words anywhere?

 

[EngineerTex]

Try skirt, rim, bell, ring, girdle, hoop, upset, band, radial protuberance or concatenated washer.

I know that this isn't the grammar forum, but the word "race" is not a protrusion. The race is the groove cut into a bearing housing where the rolling elements run.

Engineering is not the science behind building. It is the science behind not building.

 

[TerryR1]

What if I were to tell you that it was a race? =)

Noted about the wrong forum thing... I wasn't sure where to post. Can you suggest a better place? I still want to find a good list of terms. Regular Thesaurusi (haha) don't seem to list mechanical meanings for the terms. =(

 

[KENAT]

This forum is as good as anywhere since you are asking for a technical term rather than a more general grammar issue.

EngTex was I think just pointing out that race is the wrong sex, if you catch my drift.

KENAT is right. There's nothing wrong with posting your question here. I was perhaps being a little overzealous with my own apologetic paragraph regarding the word "race."

I will also give kudos for your proper use of the subjunctive, TerryR1.

Engineering is not the science behind building. It is the science behind not building.

Terry,

I would see if there is an ISO or ANSI/ASME standard that covers standard terminology/vocabulary/nomenclature for mechanical components, drawings, etc. I am familiar with a number of ISO standards for vocabulary, but not on this particular point. A quick search of the ISO standards website returned 418 standards that include the word vocabulary:

TerryR1,

In manufacturing, parts are identified by part number. The name of the part is just a description. If your part name is unique on the parts list, it is good enough.

A turned protrusion on a shaft is a flange. You can call it FLANGE, and some one or two word description indicating its function. This should be good enough.

I hate it when people make up long, $64,000 part names. There is no need to describe your assembly tree. You need to have consideration for manufacturing types to type by hunting and pecking, or who have to write things out by hand. If they do not like your name, everyone will make up colourful nicknames for your part. Beware of acronyms.

The opposite of a groove is a ridge.

TVP, I don't think there's anything like that, closest is probably ASME Y14.38 abbreviations. Something like 14.5 may implicitly define some terms like counter bore, countersink, counter drill etc. but not as an exhaustive list.

While it's not completely clear what application the OP is using these for, be it part/drawing naming or perhaps naming 'features' in the CAD feature tree or some kind of tech pubs applications, I have to generally agree with Drawoh - it's the part/drawing number that's really important.

Hmm looks like CoryPad and Clyde38 schooled all of us... Thanks & sorry for not finding that forum earlier. This thread should be moved or closed I suppose.

@KENAT - I was looking for good words mostly for use in discussion and presentation. These words aren't used anywhere on the drawings, which as you said rely on numbers.

I've been working on a photo glossary of descriptive terms. In repair manuals these descriptive terms are used. Sometimes no one but the author knows what in heck they are talking about:

my examples:
cheek - as in "crankshaft cheek"
land - as in piston land
shank
journal
port
