There is no interchangeability between B Exceptions This standard does not apply to: Join your peers on the Internet’s largest technical engineering professional community. Register now while it’s still free! As for material of a key, all three standards state that: For example, in terms of tolerances products manufactured to B In layman terms, what is “engineering”? The intent of this document is to offer designers and users of flexible couplings g773 dimensions, tolerances and fits for metric bores and keyways.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Suggestions for improvement of this standard will be welcome.
Parallel keys ISO R773
Close this window and log in. 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. Or, in more precise terms: Width Height Length Material Hardness Finish plating It is not clear to me from your two prior posts that you accomplished that.
Quantity must be a positive whole number. Shaft keyseat dimensions and tolerances were given in ISO R To fully and unambiguously define a rectilinear key you need: Bores are to be measured prior to cutting the keyway. Are you an G773 professional? 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.
In terms of dimensioning and tolerancing of keys and keyways the standards focus solely on aspect of size of features, without paying any r737 to other r773 geometric characteristics, like orientation and location of a keyway relative to axis is shaft and housing.
Or to say it another way – answer every possible question about the part before it can be asked. At the time of publication, the edition indicated was valid. Download Now Defense manufacturing is all about project manufacturing and project accounting. This specification includes index tolerances for multiple keyways.
When other materials and properties are required, these shall be as agreed upon by the supplier and customer.
This drives the quality of information on your parts list. And there is one more thing to be mentioned: Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. These characteristics have to be somehow controlled to make everything working properly.
That is different from 20 x 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 annexes also include the recommended design practice for tapered shafts for use with flexible couplings. All standards are subject to revision, and parties 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.

Defense manufacturing is all about project manufacturing and project accounting. We are not even going into tapered, low profile, woodruff, etc.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. The way to avoid this – or similar mistakes – in the future is to always provide complete and unambiguous information. 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.
It is not clear from rr773 second post what may be included in the “certain companies number”. The keys and keyways followed the recommendations of ISO R 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.
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 iwo key was specified, then no problem.
The Eng-Tips staff will check this out and take appropriate action. They may be submitted to tech agma. I don’t have either standard. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
