Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
The intent of this document is to offer designers and users of flexible couplings preferred dimensions, tolerances and fits for metric bores and keyways. Or to say it another way – answer ios possible question about the part before it can be asked. 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. Hardened keys shall be alloy steel through hardened to a Vickers hardness of to HV.
For example, in terms of tolerances products manufactured to B These characteristics have to be somehow controlled to make everything working properly. It’s easy to join and it’s free. The annexes also include the recommended design practice for tapered shafts for use with flexible couplings. Defense manufacturing is all about project manufacturing and project accounting.
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. Promoting, selling, lso, coursework and thesis posting is forbidden.
I figure that a clerical level person should able to take your parts list and order the parts isso it such that you can assemble the system and it will work. Click Here to join Eng-Tips and talk with other members! What is even worse, some dimensions given in the standards, like depth of a keyway in shaft t1 and housing t2 are nonverifiable. The Eng-Tips staff will check this out and take appropriate action. Join your peers on the Internet’s largest technical engineering professional community.

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

Regarding unambigous key designation, according to the ANSI a key shall be designated by the following data: This drives the quality of information on your parts list. Shaft keyseat dimensions and tolerances were given in ISO R There is no interchangeability between B Therefore, this standard does not intend to replace any existing metric standards, but to define what is preferred.
And there is one more thing to be mentioned: Register now while it’s still free! Red Flag This Post Please let us know here why this post is inappropriate. Failing that, you need a fabrication drawing with dimensions and tolerances.

It is not clear from your second post what may be included in the “certain companies number”. At the time of publication, the edition indicated was valid. SCOPE This standard presents metric dimensions, tolerances, sizes and fits for straight bores, tapered bores, keys and keyways for unmounted industrial flexible couplings.
Digital Transformation r73 be defined in a number of different ways by analysts or enterprise software vendors. To fully and unambiguously define r73 rectilinear key you need: Or, in more precise terms: When other materials and properties are required, these shall be as agreed upon by the supplier and customer.
Close this window and log in. They may be submitted to tech agma. I don’t have either standard. 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 isi to axis of shaft and housing.
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. Isk must be a positive whole number.
