FCL TypePin Coupling With Elastic SleeveIt Is An Elastic Transmission Component That Meets Industry Standards, With Optimized Structural Adaptability Based On The TL Type, Widely Used In Small And Medium-sized Power Transmission Systems. Its Core Structure Includes Two Flanged Half Couplings, Elastic Sleeves (made Of Rubber Or Polyurethane Material), And Column Pins. Half Couplings Are Often Made Of HT200 Cast Iron Or 45 Steel And Are Fixed To The Shaft Through Key Connections. The Column Pins Pass Through The Elastic Sleeves And Cooperate With The Pin Holes Of The Two End Half Couplings To Transmit Torque.

During Operation, The Elastic Sleeve Undergoes Elastic Deformation Between The Column Pin And The Pin Hole, Which Can Achieve Flexible Torque Transmission And Compensate For Axial (≤ 2mm), Radial (≤ 0.15mm), And Angular (≤ 1 °) Offsets Between The Two Shafts. At The Same Time, It Absorbs Vibrations, Buffers Start-up Impacts, And Reduces Equipment Operating Noise. Its Transmission Torque Range Is 16~16000N · M, And The Allowable Speed Decreases Step By Step With The Increase Of The Model. The Minimum Allowable Speed Of The Model Can Reach 8000r/min, And The Maximum Model Is About 950r/min. It Is Suitable For Medium And Low Speed Transmission Of Motors, Pumps, Fans And Other Equipment.

The Significant Advantage Of This Coupling Is That It Is Easy To Install And Maintain, And The Elastic Sleeve Can Be Replaced Separately After Wear, Without The Need To Disassemble The Half Coupling; Compact Structure And Low Cost, The Cast Iron Material Version Has Outstanding Cost-effectiveness, Suitable For Scenarios With High Economic Requirements. However, It Should Be Noted That The Temperature Resistance Range Of The Elastic Sleeve Is Limited (-30 ℃~60 ℃), And It Is Prone To Aging In Oil Stains Or High Temperature Environments For A Long Time. It Is Necessary To Regularly Check Its Cracks Or Hardening Condition. When Selecting, The Material Should Be Chosen Based On The Shaft Diameter, Rated Torque, And Working Condition Medium. During Installation, The Alignment Accuracy Of The Two Shafts Should Be Ensured To Avoid Premature Failure Of The Elastic Sleeve Due To Unbalanced Load.
