To fully and unambiguously define a rectilinear key you need: I Googled “Standard Metric Keys” and the first hit I got told me that for a 75mm diameter shaft the “standard key size” is 22mm wide x 14mm high.
If not then the people who told you you didn’t know what you were talking about – while perhaps being a tad harsh – did possibly d773 a point. Quote MintJulep One of the problems with “standards” rr773 that there are so many of them – often for the same thing – and they are rarely all the same. 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.
Item Detail – ANSI/AGMA B15
Defense manufacturing is all about project manufacturing and project accounting. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students ios their homework. And there is one more thing to be mentioned: Are you an Engineering professional?
Download Now White Paper: For example, in terms of tolerances products manufactured to B Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Or, in more precise terms: Regarding unambigous key designation, according to the ANSI a key shall be designated by the following data: 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”.
One of those has to be supplied though. There is no interchangeability between B It is not clear from your second post what may be included in the “certain companies number”. It’s easy to join and it’s free. As for material of a key, all three standards state that: Therefore, this standard does not intend to replace any existing metric standards, but to define what is preferred.
Failing that, you need a fabrication drawing with dimensions and tolerances. Red Flag This Post Please let us know here why this post is inappropriate. Hardened keys shall be alloy steel through hardened to a Vickers hardness of to HV. The intent of this document is to offer designers and users of flexible couplings preferred dimensions, tolerances and fits for metric bores and keyways.

Bores are to be measured prior to cutting the keyway. Inspection methods for straight and tapered isl and keyways are included in the annexes. That is different from 20 x Suggestions for improvement of this standard will be welcome.
The Eng-Tips staff will check this out and take appropriate action. Join your peers on the Internet’s largest technical engineering professional community. Perhaps if the size, shape, tolerance, material and finish of the key was given on a specific “standard” and that specific standard was quoted when the key was specified, then no problem. This specification includes index tolerances for multiple keyways.

I figure that a clerical 7r73 person should able to take your parts list and order the parts on it such that you can assemble the system and r7773 will work.
These characteristics have to be somehow controlled to make everything working properly. When other materials and properties are required, these shall be as agreed upon by the supplier and customer. They may be submitted to tech agma.
The way to avoid this – or similar mistakes – in the future is to always provide complete and unambiguous information.
It was approved as an American National Standard on February 4, We are not even going into tapered, low profile, woodruff, etc. What is even worse, some dimensions given in the standards, like depth of a keyway in shaft t1 and housing t2 are nonverifiable. Shaft keyseat dimensions and tolerances were given in ISO R Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. Very often keystock is sold in some arbitrarily long length – a foot, or a yard, or a meter – with individual keys cut to length from that stock by the user.
