FX Series CX Series FXL Series RA/RAHS Series The Reinvention of the Gear Coupling

Gear Coupling Selection Process Factors Affecting Selection The following is a list of the information necessary to assist in making a coupling selection. Not all of these items will come into play in all selection processes. These items include, but are not limited to: • Application details • Type of motor and driven equipment • Motor horsepower or KW • Operating/coupling speed • Shaft sizes and separation • Space and size constraints • Environment (temperature, chemicals, etc) • Balance requirements • Special modifications Steps In Selecting A Gear Coupling Refer to the gear coupling...

Notes: • 1 indicates: If people are transported, Lovejoy does not recommend and will not warranty the use of the coupling. • alues contained in the table should be used as a general guide and are to be applied to smooth power sources such V as electric motors and steam turbines. • or drives involving internal combustion engines add 1.0 to the values listed.

FX Series Flange Style Gear Coupling By incorporating the latest advances in Finite Element Analysis technology, Lovejoy has revolutionized the Gear Coupling. Increased nominal torque, larger maximum bore size and longer service life are just a few of the many advantages of the FlercuFlex coupling. Despite the advanced nature of these improvements, the FlercuFlex Gear Coupling still utilizes the standard AGMA flange interface to ensure field interchangeability. Key Features • Unequaled bore and torque capacity • 1.5° of misalignment per gear mesh • Improved fastener corrosion resistance •...

RA and RAHS Type Rigid Adjustable Couplings The RA and RAHS couplings are offered in two different styles. Type II coupling consists of two rigid hubs, adjusting nut and split ring and split ring for motor bub. Type IV coupling consists of two rigid hubs, adjusting nut, and split ring for motor hub and spacer. Key Features • Axial positioning of the pump impeller in vertical pump applications • Clearance fit bores allows for easy installation and maintenance for pump and/or motor • Easily adjustable for vertical clearance • Removable spacer for easy maintenance • AISI 1045 Steel • Stainless...

Ordering Information • Clearance fit bores with set screw are standard. • RA couplings meet standard tolerances. • Inch bore and keyway tolerances conform to AINSI / AGMA 9002-B04. • For metric bore and keyway tolerances, consult Lovejoy Application Engineering. • RAHS couplings conform to API 610 8th edition tolerances.

HERCUFLEX CONTINUOUS SLEEVE COUPLINGS HercuFlex Continuous Sleeve Gear Couplings Vertical Floating Shaft Type The upper coupling is a Standard Vertical Type coupling. The lower coupling has a hardened crowned button inserted in the plate of the lower hub and a hardened flat button inserted in the plate of the upper hub. The entire floating assembly rests on these two buttons which carry the weight of the floating assembly thus maintaining the spacing between the two lower hubs allowing for flexibility. The hubs on the floating shaft are flexible and the hubs of the driver and driven shafts...
