KC Roller Chain Chain CouplingIt Is A Rigid Movable Coupling That Relies On Chain Meshing Transmission, Consisting Of Two Half Couplings With Chain Wheels, Roller Chains, And Protective Covers. The Half Coupling Is Forged With 45 # Steel, And The Sprocket Tooth Profile Meets The GB/T 1243 Standard. It Is Connected To The Shaft Through A Flat Key. The Roller Chain Is Made Of High-quality Alloy Steel, And The Chain Links Are Treated With Carburizing And Quenching To Improve Wear Resistance.

During Operation, The Chain Meshes With The Sprockets At Both Ends To Transmit Torque. The Clearance Between The Chain And Sprockets Is Used To Compensate For The Radial (≤ 0.15mm) And Angular (≤ 1 °) Offset Between The Two Shafts. The Axial Offset Should Be Controlled Within 2% Of The Chain Pitch. The Transmission Torque Range Is 50~10000N · M, And The Allowable Speed Decreases With The Increase Of The Model (the Minimum Model Reaches 3000r/min, The Maximum Is About 500r/min), Suitable For Medium And Low Load Equipment Such As Fans, Water Pumps, And Machine Tools.

The Advantage Lies In Its Simple Structure, Low Cost, Easy Disassembly And Assembly, And The Ability To Replace The Chain Separately After Wear And Tear; However, The Transmission Stability Is Poor And There Is Some Noise During Operation, Which Requires Regular Lubrication. Working Temperature -20 ℃~100 ℃, Not Suitable For High-speed Or Frequent Forward And Reverse Working Conditions. During Installation, It Is Necessary To Ensure The Parallelism Of The Two Sprocket Axes, And The Protective Cover Should Be Firmly Fixed, Which Is A Common Choice For Economical Transmission.
