定义
A specialized washer used in preload adjustment mechanisms to secure fasteners against rotational loosening caused by vibration, thermal cycling, and dynamic operational forces. It functions by creating frictional resistance or mechanical interference between the fastener and mating surface, ensuring consistent preload maintenance critical for precision machinery alignment and performance.
工作原理
Works by generating axial tension and radial expansion when compressed under a fastener, creating spring-like action that maintains clamping force. Some designs feature teeth or serrations that bite into mating surfaces, providing mechanical locking through deformation or interference fit.
材料
Typically made from spring steel (SAE 1070-1095)stainless steel (AISI 304/316)or alloy steel. May feature zinc platingphosphate coatingor dichromate treatment for corrosion resistance.
Hardness
HRC 40-50
Thickness
0.5-3 mm
Load Capacity
50-500 N
Inner Diameter
4-25 mm
Outer Diameter
8-50 mm
Temperature Range
-40°C to 250°C
标准
ISO 7085DIN 6796ANSI B18.21.1

常见问题

How does a locking washer differ from a standard washer?

Locking washers incorporate design features like teeth, serrations, or spring action to prevent rotational loosening, while standard washers primarily distribute load.

Can locking washers be reused?

Generally not recommended as deformation and wear reduce effectiveness. Single-use ensures optimal locking performance.
