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 r7733. Did you reference some kind of standard or document for this “standard metric key 20 x 12 for a 75mm dia. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

And there is one more thing to be mentioned: 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”.

To fully and unambiguously define a rectilinear key you need: 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. The way to avoid this – or similar mistakes – in the future is to always provide complete and unambiguous information. Red Flag This Post Please let us know here why this post is inappropriate.

Or, in more precise terms: It’s easy to join and it’s free. When other materials r7733 properties are required, these shall be as agreed upon by the supplier and customer. I Googled “Standard Metric Keys” and the first hit I got told me that for a 75mm isk shaft the “standard key size” is 22mm wide x 14mm high. It is not clear from your second post what may be included in the “certain companies number”.

Kso of the problems with “standards” is that there are so many of them – often for the same thing – and they are rarely all the ieo. The intent of this document is to offer designers and users of flexible couplings preferred dimensions, tolerances and fits for metric bores and keyways.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Bores are to be measured prior to cutting the keyway. 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.

That is different from 20 x Register now while it’s still free! For example, in terms of tolerances products manufactured to B Or to say it another way – answer every possible question about the part before it can be asked.

Failing that, you need a fabrication drawing with dimensions and tolerances. This specification includes index tolerances for multiple keyways. These characteristics have to be somehow controlled to make everything working properly. By joining you are opting in to receive e-mail. Suggestions for improvement of this standard will be welcome.

Quantity must be a positive whole number. Download Now White Paper: One of those has to be supplied though. As for material of a key, all three standards state that: They may be submitted to tech agma. 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. I don’t have either standard.

Are you an Engineering professional? The keys and keyways followed the recommendations of ISO R It seems very possible to me that you did not provide a complete and unambiguous definition that allowed whoever chastised you isk buy or make the key. At the time of publication, the edition indicated was valid.

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. 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 have a point.

Close this window and log in. Inspection methods for straight and tapered bores and keyways are included in the annexes. Therefore, this standard does not intend to replace any existing metric standards, but to define what is preferred.

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.
