Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 11616-1989 "belt size" compared with the GB/T 11616-1989, the main technical changes are as follows.
--- Increasing the specific values \u200b\u200bshown and pitch line differential (see Figure 1 and Table 1);
--- Increased tape length and bandwidth requirements double sided tape (see 3.3 and Table 6);
--- Deleted XXL belt length code (see 1989 edition Table 6).
This standard uses redrafted law revision using ISO 5296.2012 "pitch belt drive models MXL, XXL, XL, L, H,
XH and XXH belt metric and inch dimensions. "
This standard and ISO 5296. compared to 2012 in the structure of the order of the clauses were adjusted.
This standard and ISO 5296.2012 is a technical difference.
--- Increasing the specific values \u200b\u200bshown and pitch line differential (see Figure 1 and Table 1);
--- Added Section line length formula [see equation (1)].
The standard proposed by China Machinery Industry Federation.
This standard by the National Standardization Technical Committee of the pulley and the belt (SAC/TC428) centralized.
This standard was drafted. Ningbo Fulong Synchronous Belt Co., Ltd., machine Productivity Promotion Center, Ningbo Kai Chi Belt Co., Ltd., Ningbo Bei
