LJJElastic Pin CouplingIt Is An Elastic Transmission Component With A Double Half Coupling Structure, Designed Specifically For Transmission Systems With Low To Medium Loads And Frequent Start Stop Requirements. Its Structure Consists Of Two Flanged Half Couplings, Nylon Elastic Column Pins, And Limit Plates. Half Couplings Are Often Made Of Forged 45 Steel Or Cast Iron, And Are Rigidly Connected To The Shaft Through Flat Keys. The Column Pins Are Evenly Distributed On The Circumference Of The Flange And Pass Through Multiple Sets Of Pin Holes To Achieve Torque Transmission.

During Operation, The Nylon Column Pin Utilizes Its Own Elastic Deformation To Compensate For Axial (≤ 3mm), Radial (≤ 0.3mm), And Angular (≤ 2 °) Offsets Between The Two Axes. It Has Stronger Tolerance For Deviations Than The LJ Type, And Can Absorb High-frequency Vibrations And Buffer Start-up Impacts. The Transmission Torque Range Is 125~50000N · M, And The Allowable Speed Is 4500~600r/min (increasing By Model), Suitable For Equipment With Certain Operating Conditions Such As Crushers And Mixers.

Compared To The LJZ Model, Its Brake Free Wheel Design Is Lighter And More Compact In Axial Size, Making It Suitable For Space Constrained Scenarios. Nylon Column Pins Are Wear-resistant And Lubrication Free, And Can Be Replaced By Simply Removing The Baffle, Resulting In High Maintenance Efficiency. However, Attention Should Be Paid To The Temperature Resistance Range Of The Column Pin (-20 ℃~80 ℃) To Avoid Contact With Strong Corrosive Media. During Installation, It Is Necessary To Control The Alignment Error Of The Two Axes To Prevent Premature Fracture Of The Column Pin Due To Unbalanced Load. This Is The Preferred Solution In Industrial Transmission That Balances Elasticity And Economy.
