China Spring Washers Factory - Industrial Open Gasket Suppliers for Bolt Stress Relaxation Solutions
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.
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 main functions of a spring washer?
A spring washer provides excellent anti-loose and anti-seismic effects, helping to keep bolted connections secure under dynamic loads and vibrations.
How does the thread and spiral direction prevent loosening?
While the general direction of the thread is right-handed, the spiral direction of the spring washer is left-handed, which physically resists the loosening rotation of the nut.
What happens when the nut is tightened over a spring washer?
Tightening the nut flattens the spring washer, which generates a continuous elastic reaction force that compels and secures the screw threads.
Why do fasteners loosen during vibration?
When subjected to the axial force of vibration, the elastic deformation of fastener parts can temporarily create gaps, making the assembly prone to loosening.
How does the oblique mouth of the spring washer work?
The tip of the spring washer's oblique mouth presses firmly against the supporting surface of the bolt, nut, or connected part. This mechanical bite compensates for instantaneous gaps and prevents loosening.
