China Suppliers Factory Ruisu Spring Washers for Industrial Applications - Prevent Bolt Stress Relaxation
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.
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.
Q1 What primary functions do spring washers provide?
Spring washers provide a highly effective anti-loose and anti-seismic performance when integrated into fastener assemblies.
Q2 What is the relationship between the thread and spiral directions?
Generally, the thread direction is right-handed, while the spiral direction of the spring washer is left-handed to ensure proper locking functionality.
Q3 How does the spring washer interact with screw threads upon tightening?
Once the nut is tightened, the washer flattens and generates an elastic reaction that directly compels the screw threads to maintain tension.
Q4 Why do fasteners loose their grip under vibration?
Under axial vibration forces, the elastic deformation of the stressed parts can create structural gaps between the fasteners, making them highly susceptible to loosening.
Q5 How does the oblique mouth design prevent loosening?
The tip of the spring washer’s oblique mouth presses firmly against the supporting surface of the bolt, nut, or connected component. This action compensates for any instantaneous gaps, preventing the assembly from backing off.
