Products Description
Plum Blossom Elastic CouplingIt Is A Transmission Component That Relies On Elastic Elements To Achieve Flexible Connections. The Core Structure Consists Of Two Metal Half Couplings With Protruding Claws (commonly Made Of 45 Steel, Cast Iron, Or Aluminum Alloy) And A Plum Blossom Shaped Elastic Body In The Middle, Named After The Plum Blossom Shaped Structure And Significant Elastic Properties Of The Elastic Body.
Its Core Working Mechanism Is To Transmit Torque Through The Meshing Of Elastic Body And Half Coupling Claw, While Using The Reversible Deformation Of Elastic Body To Absorb Vibration And Buffer Instantaneous Impact, Which Can Effectively Compensate For The Axial (≤ 5mm), Radial (≤ 0.5mm) And Angular (≤ 1.5 °) Deviations Between The Two Shafts, Avoiding Damage To The Equipment Caused By Rigid Connection.
Elasticity Is The Key To Determining Its Performance And Is Often Made Of Polyurethane Or Nitrile Rubber. Polyurethane Elastomers Have High Hardness And Strong Wear Resistance, Making Them Suitable For Stable Transmission Under Low To Medium Loads; Rubber Elastomers Have Better Flexibility And Outstanding Shock Absorption Effect, Suitable For High-frequency Vibration Conditions.
This Coupling Combines The Buffering Property Of Elastic Connection With The Practicality Of Compact Structure. It Does Not Require Lubrication, Is Easy To Install And Maintain, And Has A Moderate Cost. It Is Widely Used In Transmission Systems Such As CNC Machine Tools, Servo Motors, Packaging Machinery, Textile Equipment, Etc. With Low To Medium Speeds (≤ 3000r/min) And Requirements For Shock Absorption And Deviation Compensation.
It Should Be Noted That The Lifespan Of Elastomers Is Affected By Temperature (-30 ℃~80 ℃) And Chemical Media. Long Term Use Requires Checking For Aging Or Wear, Timely Replacement To Maintain Elastic Performance, And Avoiding Use In Ultra-high Temperature, Ultra-high Pressure, Or Extreme Corrosive Environments.
