There is no interchangeability between B But that still means a single unambiguous drawing of the thing exists and we are just making a distinction between “here is the drawing” and “here is where to go to look up the drawing”.

Regarding unambigous key designation, according to the ANSI a key shall be designated by the following data: Red Flag This Post Please let us know here why this post is inappropriate. Click Here to join Eng-Tips and talk with other members! Did you reference some kind of standard or document for this “standard metric key 20 x 12 for a 75mm dia. They may be submitted to tech agma.

To fully and unambiguously define a rectilinear key you need: Defense manufacturing is all about project manufacturing and project accounting. One of the problems with “standards” is that there are so many of them – often for the same thing – and they are rarely all the same. Register now while it’s still free!

Join uso peers on the Internet’s largest technical is professional community. It is not clear from your second post what may be included in the “certain companies number”. What is even worse, some dimensions given in the standards, like depth of a keyway in shaft t1 and housing t2 are nonverifiable. Suggestions for improvement of this standard will be welcome. This specification includes index tolerances for multiple keyways.


Or to say it another way – answer every possible question about the part before it can be asked.

We are not even going into tapered, low profile, woodruff, etc. This drives the quality of information on your parts list.

Quote MintJulep One of the problems with “standards” is that there are so many of them – often for the same thing – and they are rarely all the same.

Winflex T – Type TLNPE – Model with spacer – 1 short hub, 1 long hub

At the time of publication, the edition indicated was valid. In terms of dimensioning and tolerancing of keys and keyways the standards focus solely on aspect of size of features, without paying any attention to other important geometric characteristics, like orientation and location of a keyway relative to axis of shaft and housing.

It seems very possible to me that you did not provide a complete and unambiguous definition that allowed whoever chastised you to buy or make the key. Digital Transformation may be f773 in a number of different ways by analysts or enterprise software vendors. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Quantity must be a positive whole number. Therefore, this standard does not intend to replace any existing metric standards, but to define what is preferred. That is different from 20 x All standards are subject to revision, and ios to agreements based on this American National Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below.


Are you an Engineering professional? The intent of this document is to offer designers and users of flexible couplings preferred dimensions, tolerances and fits for metric bores and keyways. The way to avoid this – or similar mistakes – in the future is to always provide complete and unambiguous information.

The keys and keyways followed the recommendations of ISO R These characteristics have to be somehow controlled to make everything working properly. I figure that a clerical level person should able to take your parts list and order the parts on it such that you can assemble the system and it will work. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

One of those has to be supplied though. Shaft keyseat dimensions and tolerances were given in ISO R The annexes also include the recommended design practice for tapered shafts for use with flexible couplings. Or, in more precise terms:
