LJDElastic Pin CouplingIt Is An Elastic Transmission Component Optimized For High Load Transmission Design. The Structure Consists Of A Double Flange Half Coupling, High-strength Nylon Column Pins, And Anti Loosening Baffles. The Half Coupling Is Forged From 45 Steel And Undergoes Quenching And Tempering Treatment To Improve Impact Resistance. It Is Connected To The Shaft Through Splines Or Flat Keys, And The Column Pins Are Distributed In A Circular Array To Transmit Torque More Evenly.

Its Core Advantage Lies In Enhancing The Deviation Compensation Capability, With Axial Compensation Of ≤ 4mm, Radial Compensation Of ≤ 0.4mm, And Angular Compensation Of ≤ 2.5 °, Which Is Superior To The LJJ Type And Can Adapt To More Complex Shaft Deviation Conditions. The Transmission Torque Range Is Extended To 500~1000000N · M, With A Permissible Speed Of 3000~500r/min, Suitable For Heavy Equipment Such As Mining Machinery And Metallurgical Rolling Mills.

Compared With Similar Products, The LJD Pin Is Made Of Modified Nylon, With A Temperature Resistance Range Of -30 ℃~100 ℃ And An Aging Resistance Of More Than 30%. During Installation, Specialized Fixtures Are Required To Ensure Alignment Accuracy. During Maintenance, Only The Baffle Needs To Be Removed To Replace The Column Pin, Without The Need To Disassemble The Shaft System. It Is Necessary To Avoid Using In Strong Acidic And Alkaline Environments, Regularly Check The Wear Of The Column Pin, And Replace It In A Timely Manner When The Diameter Decreases By 5%. This Is A Reliable And Economical Choice In Heavy-duty Transmission Systems.
