Safety Warning When using Lovejoy products, you must follow these instructions and take the following precautions. Failure to do so may cause the power transmission product to break and parts to be thrown with sufficient force to cause severe injury or death. Refer to this Lovejoy Catalog for proper selection, sizing, horsepower, torque range, and speed range of power transmission products, including elastomeric elements for couplings. Follow the installation instructions included with the product, and in the individual product catalogs for proper installation of power transmission...

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. Horizontal Split Cover Design ■■Ideal for limited space ■■Allows easy access to the grid spring Lovejoy is pleased to be able to provide quality grid couplings covering a large number of industry standard sizes and lengths. The...

Selection Process Lovejoy Coupling Solutions Selection Example Application Description A company would like to use a grid coupling to connect a standard AC electric motor to a rotary lobe compressor. The electric motor is rated for 60 horsepower running at 1,760 RPM. The shaft size on the electric motor (driver) is 2-1/8 inches with a standard 1/2” square key. The shaft size on the compressor (driven) is 48 millimeters with a standard 14mm key. Both the motor and compressor shaft are 3 inches long and the gap (BSE) between the shaft ends is 1/8 inch. Step 6: Prior to finalizing the 1060...

Lovejoy Coupling Solutions Grid Spacer Style Performance / Dimensional Data Standard Grid Spacer and Half Spacer Style Couplings Horizontal Cover The Lovejoy Grid Spacer coupling is an ideal coupling for applications where there is a requirement for some vibration dampening in installations that are not close coupled. This means some amount of gap, or BSE exists between the driver and driven equipment shafts. All Lovejoy Grid Spacer Couplings are supplied with Horizontal Split Covers. The split cover design allows for quick access to the grid spring for ease of maintenance or grid...
