Motion control Couplings

SAFETYWARNING

When using Lovejoy products, you must follow these instructions and take the following precautions. Failure to do so may cause thepower 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 productcatalogs for proper installation of power transmission products. Do not exceed catalog ratings.During start up and operation of power transmission product, avoid sudden shock loads. Coupling assembly should operate quietly andsmoothly. If coupling assembly vibrates or makes beating sound, shut down immediately, and recheck alignment. Shortly after initialoperation and periodically thereafter, where applicable, inspect coupling assembly for: alignment, wear of elastomeric element, bolttorques, and flexing elements for signs of fatigue. Do not operate coupling assembly if alignment is improper, or where applicable, ifelastomeric element is damaged, or worn to less than 75% of its original thickness.For variable speed drives, variable speed pulley rim speeds must never exceed 10,500 feet per minute. Companion pulley speedsbeyond the ratings contained in this catalog are not recommended. For Fixed Center Drives, do not start until a torque arm bracket isinstalled. Failure to install torque arm bracket will cause torque arm to rotate rapidly and may cause severe injury from moving parts. Donot attempt to disassemble spring loaded pulley because parts may be thrown with sufficient force to cause injury or death.Do not use any of these power transmission products for industrial elevators, man lifts, or other devices that carry people. If the power transmis-sion product fails, the lift device could fall resulting in severe injury or death.For all power transmission products, you must install suitable guards in accordance with OSHAand American Society of MechanicalEngineers Standards. Do not start power transmission product before suitable guards are in place. Failure to properly guard these prod-ucts may result in severe injury or death from personnel contacting moving parts or from parts being thrown from assembly in the eventthe power transmission product fails.If you have any questions, contact the Lovejoy Engineering Department at 1-630-852-0500.
