 Disc CouplingsLovejoy takes great pride in being able to offer a wide variety of superior disc coupling products in models designed to meet the application needs of today’s worldwide power transmission market. Lovejoy has developed an innovative disc pack profile design revolutionary to traditional disc pack designs found in the market. /Asset/DiscFamilyPhoto.png Torsional CouplingsLovejoy offers a wide range of torsional couplings engineered to solve torsional vibration problems found in diesel engine driven equipment and other applications where torsional vibrations are prevalent. These include all internal combustion engines, reciprocating pumps and compressors, as well as variable frequency drives (VFD).Lovejoy torsional coupling are designed to dampen torsional vibrations and tune, or adjust the system’s critical speeds away from the application’s operating range. With the proper information, Lovejoy engineers can perform a Torsional Vibration Analysis or TVA for your application to assist in the selection of a torsional coupling. /Asset/torsionalproductsfamilyphoto.png  Universal JointsLovejoy has been manufacturing industrial universal joints for over 45 years. Lovejoy's industrial universal joint product line is well established and provides you with a wide range of standard and specialized products. The shape of the yoke is a special feature which results in exceptionally high strength, yet allows full, free movement of the joint. This accounts for the high horsepower capacity at high speeds. /Asset/d303-type-ujoint.jpg Shaft Locking DevicesLovejoy Shaft Locking Devices connect hubs solidly to shafts, using a keyless mechanical interference fit, to transmit torque or to withstand axial thrust. This mechanical interference fit utilizes screw tension in the Shaft Locking Device, converted into radial pressure via an inclined plane. This pressure expands the Shaft Locking Device to eliminate the gap between the hub and the shaft. The Shaft Locking Device uses the friction bond between the Shaft Locking Device and the shaft/hub to create a zero backlash connection. This connection is easily releasable to remove the mechanical interference fit.Lovejoy Shaft Locking Devices expand to fill the gap between the shaft and hub, allowing for easy installation and removal, saving time over traditional interference fit techniques. The contact pressures created using a Shaft Locking Device can be greater than traditional interference fit pressures, allowing for more torque to be transmitted or shorter hubs to be used. The easy installation also allows the hub to be positioned more accurately on the shaft, and can facilitate angular timing of the hub. /Asset/ShaftLockDevice.jpg  Grid CouplingsLovejoy is pleased to be able to provide quality grid couplings covering a large number of industry standard sizes and lengths. The Lovejoy grid style coupling has proven itself in performance and popularity over a wide range of applications.Lovejoy's grid style coupling design has demonstrated its ability to dampen vibration by as much as 30% and can cushion shock loads that could cause damage to both the driving and driven equipment. The tapered grid spring design absorbs impact energy by spreading the energy out over the full length of the grid spring thus reducing the magnitude of the torque spikes. The Lovejoy design uses a curved hub tooth profile which creates a progressive contact with the flexible grid spring as the application torque increases. This feature provides a more effective and efficient transmission of power in properly aligned couplings. Lovejoy's versatile design of industry standard hubs and grid springs for both horizontal and vertical cover styles allow Lovejoy couplings to be interchangeable with other industry standard grid couplings and components. Proper grid coupling installation and maintenance can add to a longer coupling life. Grid spring replacement is simple and can be performed at a fraction of the cost and time of a complete coupling. /Asset/a1425.jpg  Rigid Compression Couplings(18) Rigid Compression CouplingsResists Breakage, Built for Strength and Toughness The design of the rigid compression couplings is ideal for tough applications where strength and affordability are important. The cast steel couplings are an excellent choice for joining two shafts of the same size. This type The kind of coupling is also known as a "rigid clamp style" coupling. Made from cast steel, castings are first rough machined. A 1/16" spacer is placed between the coupling halves which are bolted together for final boring. The spacer is removed and the result is a compression clamp on the shaft. Choose from standard sizes for shafts 1-7/16" through 5". /Asset/GD-Coupling2.jpg  Coupling ConfiguratorThis tool is designed to provide those on the front lines (distributors, end users, field reps) the ability to quickly size Lovejoy’s most popular couplings. The quick reference feature does not ensure a given coupling fully meets an application’s required needs, but will validate torque & RPM. To ensure a proper selection, you must reference the product specific catalog and rely on Lovejoy’s Application Engineers for technical assistance. The coupling types included in this configurator do not represent Lovejoy’s full offering. If there is a coupling type you are interested in but do not see, please contact Lovejoy directly.Begin by entering:
