Star Shaped Coupling Elastic BodyIt Is The Core Elastic Element Of The Star Shaped Coupling, With A Plum Blossom Or Star Shaped Structure, Usually Molded From Polyurethane, Nitrile Rubber Or Silicone Rubber Materials. Its Center Is Connected To The Flange, And Multiple Convex Claws Are Evenly Distributed On The Outer Edge, Which Are Fitted Into The Grooves Of The Half Couplings At Both Ends Of The Coupling To Form A Flexible Force Transmission Structure.

As A Key Component For Torque Transmission, Elastomers Achieve Power Transmission Through Their Own Deformation, Compensating For Radial (≤ 0.3mm), Angular (≤ 1.5 °), And Axial (≤ 1mm) Offsets, While Absorbing Vibrations, Buffering Impacts, And Reducing Equipment Operating Noise. Polyurethane Material Elastomer Has Excellent Wear Resistance And Adjustable Hardness (Shore A 60~90), With A Temperature Resistance Of -30 ℃~80 ℃; Rubber Material Has Better Elasticity And Is Suitable For High-frequency Vibration Conditions, But Its Oil Resistance Is Slightly Inferior.

The Service Life Of Elastomers Is Usually 1500~3000 Hours. It Is Necessary To Avoid Long-term Exposure To Ozone And Strong Acids And Bases. During Installation, It Is Necessary To Ensure That The Protrusions And Grooves Are Not Stuck To Prevent Local Overload Tearing. Suitable For Precision Transmission Systems Such As CNC Machine Tools, Servo Motors, Packaging Machinery, Etc., It Is The Core Guarantee For Flexible Connection Of Star Couplings.
