Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 12458-2003 "Coupling classification". This standard compared with GB/T 12458-2003, in addition to editorial
The main technical changes are as follows.
--- 5.2, the title of the article changed to "the coupling of the group code, variety code, structure type code", the other part of the modified to 5.2
content;
--- modified the plum-shaped elastic coupling and elastic pin pin coupling type of classification.
This standard is proposed and assigned by the National Committee on Standardization of Machine Shaft and Accessories (SAC/TC109).
