标准简介
OVERVIEW中文简介
该标准规定了波形弹簧垫圈的尺寸、公差、技术要求及标记方法。它适用于与性能等级低于5.8的紧固件配合使用的螺栓/螺母组件,旨在防止因沉降效应导致的松动,但不适用于承受变化径向载荷的场合。
English summary
This standard specifies the dimensions, tolerances, technical requirements, and designation for wave spring washers. It applies to bolt/nut assemblies with fasteners of property class less than 5.8, intended to counteract loosening caused by settling effects, but is not suitable for assemblies under varying radial loads.

1 Scope and field of application
Spring lock washers as covered in this standard are deemed to be spring washers designed for use with bolt/nut assemblies involving fasteners of a property class less than 5.8, as specified in DIN EN 20 898 Part 1. They are intended to counteract the effect of setting which results in bolt/nut assemblies working loose (see DIN 267 Part 26). They do not effectively prevent loosening of the assembly under varying radial load and are designed for use with short bolts predominantly subject to thrust.

1) The diameter tolerances specified apply to spring washers when pressed flat. The tolerance on coaxiality between d1 and d2 (related to d2) shall be ½ IT 14.
2) Values to be complied with in the spring force test as described in DIN 267 Part 26 have not as yet been specified for this size.
3 Technical delivery conditions
Spring washers shall be made of spring steel (FST) as specified in DIN 267 Part 26, which shall also apply with regard to the technical delivery conditions.
4 Designation
Designation of a type B washer of nominal size 8, made of spring steel (FST)1):
Spring washer DIN 137 – B8 – FSt
The DIN 4000 – 3 – 3 tabular layout of article characteristics shall apply to spring washers as covered in this standard.
Standards referred to
DIN 267 Part 26 Fasteners; technical delivery conditions; steel spring washers for bolt/nut assemblies
DIN 4000 Part 3 Tabular layout of article characteristics for washers
DIN EN 20 898 Part 1 Mechanical properties of fasteners; bolts, screws and studs (ISO 898-1:1988)
Previous editions
DIN 137: 12.43, 07.53, 10.63, 12.70, 10.87.
1) FST shall also apply where no material has been specified in existing documentation.
2
Amendments
The following amendments have been made to the October 1987 edition.
a) Type A is no longer specified.
b) Nominal sizes 39, 42, 45, 48 and 52 have been dropped.
Explanatory notes
By maintaining a sufficiently high preloading in a bolt/nut assembly, spring washers are designed to prevent loosening of the assembly, which may be caused, for instance, by the effect of settling. The specification of residual spring forces given in DIN 267 Part 26 has made it possible for the first time to assess the performance of such washers.
Although type A spring washers are no longer specified, the designation 'type B' has been retained so as to indicate that the design of this type has not been changed.
