High-Quality 1 Inch Spring Washer from China Suppliers - ANSI Open Gasket Spring Pad Factory
The spring washer has good anti-loose effect and anti-seismic effect.
Thread Direction & Elastic Reaction
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
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
Q1: 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 securing fastener combinations under stress.
Q2: Why do the thread and spring washer spiral directions differ?
The general direction of the thread is right-handed, while the spiral direction of the spring washer is left-handed. This opposing design helps prevent the nut from backing off.
Q3: How does the tightening of a nut activate the spring washer?
After tightening the nut, the spring washer is flattened. This flattening generates an elastic reaction force that tightly compels the screw threads together.
Q4: Why do fasteners tend to loosen under axial vibration?
When subjected to the axial force of bolt vibration, the elastic deformation of fastener parts under stress can create temporary gaps, making them more prone to loosening.
Q5: How does the oblique mouth of a 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. This design compensates for instantaneous gaps between fasteners to prevent loosening.
