KEYWAY SPECIFICATIONS

KEYWAY SPECIFICATIONS

KEYWAY SPECIFICATIONS

(OP)
Can anyone provide standard keyway specifications for documation purposes?  Inch sizes are most importain at this time.  I am looking for a basic formular, unlike the information in the machinist handbook.  

Thank You

RE: KEYWAY SPECIFICATIONS

Any good text book on machine design should contain all the theoretical information on keyway. Try a college/university bookstore or library for these books.

RE: KEYWAY SPECIFICATIONS

My first bit of advice would be to look up the standard on keys and keyways.  Since you are focusted mostly on inch sizes, try ANSI B17.1-1967 & B17.2-1967 which is now available through ASME @ 345 E. 47th St. New York, New York, 10017 or at www.ansi.org.

The standards, I believe, have been updated though.  You could try these from the ANSI webstore (httP://webstore.ansi.org) (http://webstore.ansi.org/ansidocstore/find.asp?).

NASM35756-1998  KEY, WOODRUFF, STEEL, ALLOY, WITH KEYWAY AND KEY SLOT DIMENSIONS (SUPERSEDING MS35756E)  $14.50  
NA0139-1993  KEYWAY AND KEY SLOT DIMENSIONS METRIC  $14.50  
ISO 3912:1977  Woodruff keys and keyways  $26.00  
ISO 3117:1977  Tangential keys and keyways  $26.00  
ISO 2492:1974  Thin taper keys with or without gib head and their corresponding keyways (Dimensions in millimetres)  $26.00  
ISO 2491:1974  Thin parallel keys and their corresponding keyways (Dimensions in millimetres)  $26.00  
ISO 2490:1996  Single-start solid (monobloc) gear hobs with tenon drive or axial keyway, 1 to 40 module - Nominal dimensions  $26.00  
ANSI/AGMA 9002-A86 (R1995)  Bores and Keyways for Flexible Couplings (Inch Series)  $43.00

Other than that, since I don't own the standard, can only give you what the Machinery's Handbook has to offer, but in a more condensed format.

P.S.

You may also want to post your question on the ANSI and ASME forums.
