Anti-Loose & Anti-Seismic Function
The spring washer has good anti-loose effect and anti-seismic effect. The general direction of the thread is right-handed, and the spiral direction of the spring washer is left-handed. After tightening the nut, the elastic reaction generated by the washer flattening compels the screw threads.
Vibration & Gap Compensation
At the same time, when the fastener combination is subjected to the axial force of the vibration of the bolt, due to the elastic deformation of each part after the stress, sometimes there will be a gap between the fasteners, which is easier to loose. The tip of the spring washer’s oblique mouth is against the supporting surface of the bolt or nut and the connected part, which can make up for the gap between the instantaneous fasteners and prevent loosening.
Frequently Asked Questions
What are the primary benefits of using a spring washer?
Spring washers provide excellent anti-loose and anti-seismic effects, helping to maintain the integrity of threaded fastener connections under dynamic loads.
How does the spiral direction of a spring washer prevent loosening?
Since standard screw threads are right-handed, the spring washer features a left-handed spiral direction. This opposing orientation creates resistance that helps prevent the nut from turning loose.
What mechanism keeps the screw threads tight?
When the nut is tightened, the spring washer is flattened. This flattening action generates a continuous elastic reaction force that tightly compels the screw threads together.
How does vibration affect fasteners, and how does the washer help?
Vibrations exert axial forces that cause elastic deformation, creating temporary gaps between fasteners. The spring washer instantly compensates for these gaps through its spring tension, keeping the assembly secure.
What role does the oblique mouth of the spring washer play?
The tip of the washer's oblique mouth presses directly against the supporting surface of the bolt, nut, or connected part. This physical bite prevents rotation and compensates for any instantaneous gaps.
