HLL TypeElastic Column Pin Coupling With Brake WheelIt Is A Transmission Component That Integrates Braking Function Based On The HL Type, Suitable For Medium Load Systems That Require Emergency Braking. The Structure Includes A Double Flanged Half Coupling, Brake Wheels, Nylon Elastic Column Pins, And Metal Baffles. The Half Coupling Is Made Of Forged 45 Steel Or Cast Iron, While The Brake Wheels Are Made Of Forged Steel And Are Fixed To The Shaft Through Key Connections. The Column Pins Transmit Torque In A Circular Distribution.

Its Deviation Compensation Capability Is Consistent With The HL Type, With Axial ≤ 3mm, Radial ≤ 0.35mm, Angular ≤ 2 °, Transmitted Torque Of 160~50000N · M, Allowable Speed Of 3500~600r/min, Braking Torque Coverage Of 200~60000N · M, Suitable For Machine Tools, Lifting Equipment, Conveyors, Etc.

Compared To The HL Type, Its Advantage Is The Integrated Design Of The Brake Wheel And Coupling, Which Saves Installation Space And Has A Fast Braking Response. The Column Pin Is Made Of Ordinary Nylon, With A Temperature Resistance Of -20 ℃~80 ℃, And A Moderate Cost. Installation Should Ensure Alignment Accuracy, And Brake Wheels Should Be Regularly Checked For Wear (allowable ≤ 2mm). After Aging Or Wear Of The Column Pins, They Should Be Replaced In A Timely Manner, Which Is A Practical Choice That Balances Transmission And Safe Braking.
