Products Description
JSGHigh Speed Snake Spring CouplingIt Is An Upgraded Model Designed Specifically For High-speed Transmission, With Optimized Dynamic Performance Based On The JS Model, Meeting The Standards Of High-speed Transmission Equipment. The Structure Retains The Half Coupling With Trapezoidal Teeth And The Core Of The Serpentine Spring, But The Half Coupling Is Made Of 20CrMnTi Alloy Carburizing Steel, Which Has Been Quenched To Improve Surface Hardness (HRC58-62), And The Tooth Groove Accuracy Reaches IT6 Level, Reducing Centrifugal Force Fluctuations During High-speed Operation.
The Snake Shaped Spring Is Made Of High-strength Alloy Steel Wire, With An Optimized Arc-shaped Cross-section Design To Reduce Air Resistance At High Speeds. The Engagement Gap Between The Spring And The Tooth Groove Is Controlled At ≤ 0.05mm To Reduce Impact Noise. It Can Compensate For Axial (≤ 8mm), Radial (≤ 0.4mm), And Angular (≤ 1 °) Deviations, With A Torque Transmission Range Of 800~150000N · M And An Allowable Speed Increase Of 6000~1500r/min (far Exceeding JS Type), Suitable For Equipment Such As Steam Turbines, High-speed Pumps, Centrifugal Compressors, Etc.
The Shell Is Made Of Lightweight Aluminum Alloy And Has A Built-in Labyrinth Seal To Prevent Grease Leakage At High Speeds. The Working Temperature Is -40 ℃~150 ℃. Installation Requires Passing A Dynamic Balance Test (G2.5 Level Or Above), And Regular Inspection Of Spring Fatigue Cracks Is Necessary During Maintenance. It Is A Precise Choice For High-speed, Medium High Load Transmission.
