China Spring Washers from Reliable Suppliers | Industrial Open Gaskets Manufacturer Factory
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
Q
What are the primary benefits of using a spring washer?
A spring washer provides excellent anti-loose and anti-seismic effects, helping to secure fasteners and prevent them from loosening under vibration.
Q
What is the relation between the thread and spiral directions of a spring washer?
Generally, the thread direction of the bolt is right-handed, while the spiral direction of the spring washer is designed to be left-handed to ensure proper locking action.
Q
How does a spring washer apply force to prevent loosening?
Once the nut is tightened, the spring washer is flattened. This creates an elastic reaction force that continuously compels the screw threads together, maintaining tension.
Q
Why do fasteners become loose under vibration, and how does the washer help?
Vibration exerts axial forces causing elastic deformation in the fasteners, which can create temporary gaps. The spring washer prevents loosening by instantly compensating for these gaps with its stored elastic energy.
Q
What role does the oblique mouth of a spring washer play?
The tip of the spring washer's oblique mouth presses firmly against the supporting surface of the bolt, nut, and the connected part. This physical contact makes up for any instantaneous gaps, preventing the assembly from backing off.
