This Lovejoy LF30 Drive Coupler is a key part of the LF Series Torsional coupling system. It specifically addresses problematic torsional vibrations common in diesel engine equipment. The coupling’s core is the LF30 flexible elastomeric element. This element is torsionally tuned to shift harmful resonance frequencies outside the operating range. The LF30 handles a nominal torque of approximately 4,400 in·lb (500 Nm).
Product Quality and Function
Stark Industrial Products supplies only high-quality drive couplings. We guarantee every unit is Original Equipment Manufacturers’ (OEM) equipment. We use only OEM, unless we match a discontinued item.
- The coupling protects coupled equipment from dangerous torsional vibrations, shock loads, and reaction forces.
- Its simple, effective design ensures fail-safe operation. Radial screws connect the element to the cylindrical hub; axial screws attach the element to the flanged hub.
- Available element materials, such as Hytrel, resist oil, heat, and corrosion. This makes the coupling ideal for harsh environments like combustion engine and hydraulic pump applications.
- The design is maintenance-free, needs no lubrication, is electrically insulating, and handles substantial shock, vibration, and misalignment (angular, parallel, and axial).
Industry Applications and Brands
Our couplings suit many industrial power transmission applications. They focus strongly on equipment driven by combustion engines and electric motors.
- The versatility of the LF Series allows for configurations such as shaft-to-shaft and engine flywheel-to-shaft (Model 1). We often use it with SAE-standard flywheels.
- Optional S-Style bolts permit “blind” assembly installations, such as inside a bellhousing, and also handle free end float.
- Some of the leading equipment and heavy machinery brands we supply drive couplings for include LOVEJOY (a Timken Company), REICH-KUPPLUNGEN, Guascor, Caterpillar, MAN, MTU, ZF, Allison, and other major engine-driven machinery manufacturers.
