Quick Cold InstallationSerpentine Spring CouplingIt Is An Efficient Assembly Solution Optimized For Traditional Hot Assembly Processes, Suitable For Scenarios That Require Quick Replacement Or Emergency Maintenance. Its Core Is To Use The Principle Of Low-temperature Shrinkage To Cool The Serpentine Spring And Half Coupling Tooth Groove Through Dry Ice (-78.5 ℃) Or Liquid Nitrogen (-196 ℃), And To Achieve Rapid Assembly Of Interference Fit By Utilizing The Thermal Expansion And Contraction Characteristics Of Metal.

The Operation Steps Are Simple: First, Place The Spring And Half Coupling Tooth Groove Assembly Into A Low-temperature Container, Cool For 10-30 Minutes (depending On The Size), Wait For It To Shrink To The Assembly Gap (usually 0.1-0.3mm), Quickly Remove And Align It With The Shaft End, And Push It. At Room Temperature, The Material Can Rebound To Complete The Fastening. No Heating Equipment Is Required Throughout The Process, And The Assembly Time Is Shortened By More Than 60% Compared To Hot Installation.

This Process Can Avoid Material Performance Degradation Caused By Hot Fitting, Especially Suitable For The Assembly Of 60Si2MnA Spring Steel, And Can Maintain Its Fatigue Resistance Characteristics. Attention Should Be Paid To Wearing Low-temperature Protective Equipment During Cold Installation To Avoid Frost Formation Caused By Contact Between Components And Humid Air, Which May Affect The Accuracy Of Fitting. After Cold Installation, It Is Necessary To Let It Stand For 30 Minutes Until The Temperature Is Balanced, And Then Check The Meshing Status Of The Teeth. This Is An Efficient Choice For Emergency Maintenance Of High Load Equipment.
