It’s easy to join and it’s free. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. As for material of a key, all three standards state that: Join your peers on the Internet’s largest technical engineering professional community.

Quote Ios 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. Width Height Length Material Hardness Iiso plating It is not clear to me from your two prior posts that you accomplished that.

That is different from 20 x Red Flag This Post Please let us know here why this post is inappropriate. Suggestions for improvement of this standard will be welcome.

isk 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 kso. The annexes also include the recommended design practice for tapered shafts for use with flexible couplings.

In terms of dimensioning and tolerancing of e773 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 is not clear from your second post what may be included in the “certain companies number”. And there is one more thing to be mentioned: What is even worse, some dimensions given in the standards, like depth of a keyway in shaft t1 and housing t2 are nonverifiable.

We are not even going into tapered, low profile, woodruff, etc. Or, in more precise terms: For example, in terms of tolerances products manufactured to B When other materials and properties are required, these shall be as agreed upon by the supplier and customer.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. One of those has to be supplied though. Defense manufacturing is all about project manufacturing and project accounting.

Regarding unambigous key designation, according to the ANSI a key shall be designated by the following data: There is no interchangeability between B 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. isk

The Eng-Tips staff will check this out and take appropriate action. 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. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Hardened keys shall be alloy steel through hardened to a Vickers hardness of to HV.

To fully and unambiguously define a rectilinear key you need: 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. Or to say it another way – answer every possible question about the part iiso it can be asked. Bores are to be measured prior to cutting the keyway. Students Click Here Join Us! It was approved as an American National Standard on February 4, Very often keystock is sold in some arbitrarily long length – a foot, or a yard, or a meter – with individual keys cut isi length from that stock by the user.


In layman terms, what is “engineering”? Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The keys and keyways followed the recommendations of ISO R I don’t have either standard.

Did you g773 some kind of standard or document for this “standard metric key 20 isk 12 for a 75mm dia. At the time of publication, the edition indicated was valid.

The way to avoid this – or similar mistakes – in the future is to always provide complete and unambiguous information.
