    Introduction

    TL350-2 torque limiter is a mechanical overload protection component designed to restrict transmitted torque in rotating drive systems. When shock loads, sudden overloads, or mechanical jams push torque beyond a preset threshold, controlled friction slipping occurs to prevent damage to motors, gearboxes, and transmission elements. Once the overload condition disappears, normal torque transmission automatically resumes without manual resetting. This adjustable friction‑type coupling serves as a reliable safeguard for industrial motion assemblies, conveyor drives, automated machinery, and experimental mechanical systems where stable torque control and equipment protection are essential.




    Adjustable Friction Torque Protection

    A spring‑loaded friction plate mechanism allows precise presetting of slip torque. Adjustment is achieved by tightening or loosening a nut or bolt that controls spring compression, which changes the friction force between plates. Once torque demand exceeds the configured threshold, controlled slipping occurs to absorb excess load and protect connected components. This friction‑based torque limiting method provides reliable mechanical protection in systems vulnerable to sudden overload conditions.


    Flexible Integration in Drive Assemblies

    The mechanical torque control unit functions as a central connection element within a power transmission chain. Sprockets, gears, sheaves, or flange plates can be mounted between friction surfaces, enabling integration into many drive configurations. The compact mechanical structure supports installation in industrial automation equipment, transmission test rigs, and motion control mechanisms that require a dependable overload protection coupling.


    Applications include conveyor protection systems, automated production machinery, drivetrain testing platforms, mechanical power transmission assemblies, and robotics motion experiments where drivetrain safety and controlled torque limiting are necessary for reliable operation.
