Coupling DiaphragmIt Is The Core Force Transmission Component Of The Diaphragm Coupling, Usually Made Of 304, 316 Stainless Steel Or Titanium Alloy Precision Stamped Into A Circular Or Polygonal Star Shape, With A Polished Surface To Reduce Stress Concentration. Its Structure Is Composed Of Multiple Thin Sheet-like Membranes Stacked Together, Connected To Both Ends Of The Flange Through Bolts, Forming A Rigid And Elastic Force Transmission Structure.

During Operation, The Diaphragm Utilizes Its Own Bending And Twisting Deformation To Transmit Torque, Compensating For Axial (≤ 2mm), Radial (≤ 0.1mm), And Angular (≤ 0.5 °) Offsets, With Transmission Accuracy Much Higher Than That Of Tire Coupling Bodies. The Temperature Resistance Range Of Stainless Steel Material Is -200 ℃~300 ℃, And The Titanium Alloy Version Can Withstand High Temperatures Above 500 ℃, With A Torque Transmission Range Of 100~1000000N · M And A Permissible Speed Of Up To 15000r/min.

Widely Used In Scenarios That Require High Transmission Accuracy, Such As Steam Turbines, Aerospace Equipment, And Precision Machine Tools. The Advantages Are No Lubrication Requirement, Long Lifespan (up To 10 Years Or More), Corrosion Resistance, And No Performance Degradation Due To Aging; However, Strict Requirements Are Placed On Installation Accuracy, And Excessive Deviation Can Lead To Premature Fatigue Fracture Of The Diaphragm. During Maintenance, It Is Necessary To Regularly Check For Cracks In The Diaphragm, Which Is The Core Component Of High-precision And High-speed Transmission.
