LJZ Elastic Column Pin CouplingIt Is A Transmission Component That Integrates Brake Wheels Based On The LJ Type, With Both Elastic Transmission And Safety Braking Functions, Suitable For Medium And Low Load Systems That Require Emergency Parking. Its Structure Includes A Flanged Half Coupling, Brake Wheel, Nylon Elastic Column Pin, And Baffle. The Half Coupling Is Made Of 45 Steel Or Cast Iron, And The Brake Wheel Is Made Of Forged Steel Material, Fixed To The Shaft Through Key Connections. The Column Pin Passes Through The Pin Holes Of The Half Coupling At Both Ends To Transmit Torque.

During Operation, The Nylon Column Pin Undergoes Deformation Compensation For Axial (≤ 2mm), Radial (≤ 0.2mm), And Angular (≤ 1.5 °) Offsets, Providing Vibration Absorption And Buffering; The Brake Wheel Achieves Emergency Braking Through Friction Components, With A Braking Torque Covering 100~25000N · M. The Transmitted Torque Is 63~25000N · M, And The Allowable Speed Is 5000~750r/min (depending On The Model), Suitable For Equipment Such As Motors, Cranes, And Conveyors.

Compared To The LJ Type, Its Advantage Is The Integrated Braking Design That Saves Space And Has A Fast Braking Response; Nylon Column Pins Are Lubrication Free And Easy To Replace. But The Brake Wheels Need To Be Regularly Checked For Wear (allowable ≤ 2mm), And The Column Pins Are Resistant To Temperatures Ranging From -20 ℃ To 80 ℃, As High Temperatures Are Prone To Aging. Installation Requires Ensuring Alignment Accuracy And Avoiding Column Pin Bias, Which Is A Practical Choice In Industry That Balances Transmission And Safety.
