Foreword
关于梦想的作文800字This document has been prepared by Working Committee NA 026-00-02 AA Tellerfedern of the Normen -ausschuss Federn, Stanzteile und Blechformteile (NAFS) (Springs, Stamped Parts and Moulded Parts Standards Committee) in DIN.
Since this edition is a corrected edition of DIN 2093:2006-03, the Amendments clau from the 2006
edition is reproduced here. In the meantime, the ISO 31 ries of standards has been replaced by the ISO 80000 ries.
Further information about NAFS can be found at www.nafs.din.de. Amendments
This standard differs from DIN 2093:1992-01 as follows:
a) examples of designation for springs produced by turning (G) and for springs produced by fine blanking (F)
are no longer included (e Clau 4); b) Clau 4 now includes the assignment of springs to ries A, B or C bad on the h 0/t ratio;
c) in Clau 7, new values of and of stress OM III II σσσ,, have been specified;
d) the standard has been editorially revid to take account of the new style rules for standards. Quantities,
symbols, units and signs have been aligned with the International System of Units (SI) as in ISO 31. The following corrections have been made to the DIN 2093:2006-03 edition: a) Corrigendum 1 from July 2007 has been incorporated;
b) in Figure 6 (Fatigue life of not shot peened disc springs with 1,25 mm ≤ t ≤ 6 mm) the maximum stress has
been corrected to 1 250 MPa; c) the drawings have been reworked to reflect the new principles on which they are bad; d) normative references have been updated.
财务总结The following corrections have been made to the DIN 2093:2013-02 edition:
a) in Table 1, column “III σ”, the value 1 419 for D e 25 disc springs in Group 2 has been corrected to 1 091; b) in Table 1, column “OM σ”, the value −1 562 for D e 25 disc springs in Group 2 has been corrected to
−1 622; Previous editions

This standard specifies the t of requirements that ensure the correct functioning of disc springs. The include requirements relating to the materials and manufacturing process, tolerances on dimensions and spring forces, and also the permissible relaxation and fatigue life of such springs as a function of stress. All requirements specified here are minimum requirements. This standard covers three dimensional ries of disc springs.

3 Terms and definitions
Disc springs are annular coned elements that offer resistance to a compressive load applied axially. They may be designed as single disc springs or as disc springs stacked in parallel or in ries, either singly or in multiples. They may be subjected to both static and fatigue loading, and may have flat bearings.
In this standard, disc springs are divided into three groups and three dimensional ries. Classification into groups is bad on the manufacturing process, which is a function of the material thickness. The assignment of disc springs to dimensional ries is governed by the h 0/t ratio.

6 Spring material
Springs complying with this standard shall be made from steel as specified in DIN EN 10083, DIN EN 10089 or DIN EN 10132-4. Carbon steel shall only be ud for the manufacture of group 1 springs (e also Table 4).
聊胜于无是什么意思NOTE The design of disc springs made from steel as above shall be bad on a modulus of elasticity E of 206 000 MPa.
The modulus of elasticity and strength property of other materials (e.g. stainless steel for springs in accordance with DIN EN 10151, copper alloys (spring bronze) in accordance with DIN EN 1654) will likely be different. The values given for F and σ in Tables 1 to 3 then cea to apply. In such cas it is recommended the spring manufacturer be consulted.
