The annexes also include the recommended design practice for tapered shafts for use with flexible couplings. Students Click Here Join Us! 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. As for material of a key, all three standards state that: Close this window and log in.

I don’t have either standard. What is even worse, some dimensions given in the standards, like depth of a keyway in shaft t1 and housing t2 are nonverifiable. It is not clear from your second post what may be included in the “certain companies number”. Download Now Defense manufacturing is all about project manufacturing and project accounting. Failing that, you need a fabrication drawing with dimensions and tolerances.

Or, in more precise terms: This specification includes index tolerances for multiple keyways. Defense manufacturing is all about project manufacturing and project accounting. When other materials and properties are required, these shall be as agreed upon by the supplier and customer.

Red Flag This Post Please let us know here why this post is inappropriate. 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. 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.


Suggestions for improvement of this standard will be welcome.

Parallel keys ISO R773

To fully and unambiguously define a rectilinear key you need: This drives the quality of information on your parts list. The intent of this document is to offer designers and users of flexible couplings preferred dimensions, tolerances and fits for metric bores and keyways.

Quantity must be a positive whole number. Posting Guidelines Promoting, selling, r77, coursework and thesis posting is forbidden.

Therefore, this standard does not intend to replace any existing metric standards, but to define what is preferred. It was approved as an American National Standard on February 4, Promoting, selling, recruiting, coursework and thesis posting is forbidden. Perhaps if the size, shape, tolerance, material and finish of the key was given g773 a specific “standard” and that specific standard was quoted when the key was specified, then no problem.

In layman terms, what is “engineering”? And there is one more thing to be mentioned:
