適用范圍：This standard specifies requirements and methods of test for conical spring washers which are intended foruse with bolt/nut assemblies as dealt with in the following standards:-- DIN 6796 Conical spring washers for bolt/nut assemblies DIN 6908, Conical spring washers for screw and washer assembliesIt is recommended that this standard also be applied for conical spring washers for bolt/nut assemblies whichhave not been standardized.Conical spring washers made from materials other than spring steel are not covered by this standard.NOTE Conical spring washers serve to counteract the loss in inherent tension caused by setting and creep of abolt/nut assembly provided that-- they are sufficiently resilient to increase the overall resilience of the assembly;-- their inherent spring force can compensate for any loss in tension so that the clamping force required to ensure the reliability of the assembly is maintained.There may be relative movement between bolt and nut if the friction between the clamped components isovercome by transverse forces. If this does occur, loosening of the assembly cannot usually be prevented byspring washers.Thus, when using these components, it should be checked whether the spring washers may usefully beemployed as the elements maintaining the clamping force.
