7、- und Gleitlager (Rolling Bearings and Plain Bearings Standards Committee). Amendments This standard differs from DIN 5406:1993-02 as follows: a) the standard has been editorially revised; b) information on masses has been deleted from Tables 1 and 2; c) types have been added by analogy with ISO 298
8、2-2; d) symbols have been largely brought into line with ISO 2982-2; e) further information on design has been added; f) the normative references have been updated. This standard contains the following corrections to DIN 5406:2009-05: a) The shaft groove width b3and the associated width of inner tab
9、 b2for bore diameters d1from 160 mm to 280 mm have been corrected.

38、Annex A (informative) Explanatory notes Lockwashers according to this standard largely conform to ISO 2982-2. This standard differs from ISO 2982-2:2001 in the following aspects: a) Tables 1 and 2 of this standard only show dimensions for the locking elements of locknuts according to DIN 981. b) Thi
39、s standard also includes the symbols for the locking elements that have been successfully used in practice. c) The dimensions for the relevant locknuts are given in a separate standard (see DIN 981); only the designation of the matching locknuts is included in the tables. d) This standard also conta
