China Suppliers Factory Ruisu Spring Washers for Industrial Applications - Effective Stress Relaxation Solution
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.
Anti-Loose & Anti-Seismic: Specifically designed to counteract vibrational forces that cause fasteners to back out.
Opposing Thread Direction: Right-handed bolt threads pair with the left-handed spiral of the spring washer to secure the joint.
Elastic Reaction: The flattening of the washer maintains constant tension on the screw threads, compensating for structural gaps.
Frequently Asked Questions
Q: What are the primary benefits of using a spring washer?
A spring washer provides excellent anti-loose and anti-seismic effects, making it highly effective in preventing fasteners from loosening under vibration.
Q: How do the spiral and thread directions of the spring washer work?
Generally, the thread direction of the bolt is right-handed, whereas the spiral direction of the spring washer is left-handed, which helps resist loosening.
Q: What happens when the nut is tightened over a spring washer?
Once the nut is tightened, the spring washer flattens and generates an elastic reaction that continuously forces and secures the screw threads together.
Q: Why do fastener combinations loosen under vibration?
When subjected to the axial force of vibration, the elastic deformation of the connected parts can create temporary gaps, making the assembly easier to loosen.
Q: How does the oblique mouth of the spring washer prevent loosening?
The tip of the spring washer’s oblique mouth presses firmly against the supporting surface of the bolt or nut and the connected part, compensating for any instantaneous gaps and preventing rotation.
