Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 5272-2002 "Plum-shaped elastic coupling". This standard compared with GB/T 5272-2002, in addition to editorial
The main technical changes are as follows.
--- increase the maximum torque of the coupling;
--- modified the coupling model of the representation;
--- removed LMD type and LMZ-Ⅱ type structure;
--- modified part of the LML-type coupling structure type;
--- modified part of the LMS-type coupling size;
--- increased the LMP type structure;
--- modified the physical and mechanical properties of the elastomer;
--- Added coupling selection instructions (see Appendix B).
This standard is proposed and assigned by the National Committee on Standardization of Machine Shaft and Accessories (SAC/TC109).
