Foreword
This section is one of the "spring washers" series of standards GB/T 94. The series includes.
--- GB/T 94.1-2008 spring washers spring washers;
--- GB/T 94.2-1987 toothed spring washers, serrated lock washer;
--- GB/T 94.3-2008 saddle-shaped spring washers, wave spring washers.
This section is GB/T Part 1 94.
This Part replaces GB/T 94.1-1987 "spring washers spring washers."
Section compared with the GB/T 94.1-1987 The main changes are as follows.
--- Modify reference standard (Chapter 2);
--- Adjustment "heat treatment" provisions (see Table 1);
--- The "toughness" to the term "reverse", the technical requirements to read. "4.2 gasket should torsion test, spring steel, stainless steel and
Can not fault phosphor bronze washers to 90 ° when twisted "(see 3.2.2).
--- Spring steel washer surface treatment increases "the non electrolytic zinc coating sheet" (see Table 1);
--- Increase a torsional view (see Figure 1).
This part is proposed by China Machinery Industry Federation.
This part of the National Standardization Technical Committee fasteners (SAC/TC85) centralized.
