What are Lovejoy gear couplings?
Lovejoy gear couplings connect rotating shafts of mechanical equipment by using gear mesh to accommodate inherent misalignment while transmitting power and torque between the shafts. There are caps on the flanks and exterior ring of the gear to allow angular movement between the gears. Gears automatically adjust proportionally to rotating splines with modified profiles. These Lovejoy gear couplings transmit power between the two ends of the coupling through the internal and external gears. Lovejoy gear couplings are very similar to flexible couplings and are capable of high torque transmission, making them ideal for heavy duty applications. They require periodic lubrication (grease) for optimum performance. These Lovejoy gear couplings feature a compact size for limited space applications.
Lovejoy gear couplings are commonly employed on large industrial machines such as pumps, blowers, compressors & mixers. They can be used in small motion control systems with a polymer sleeve, as a means of reducing backlash.
Lovejoy gear couplings are widely used in the steel industry. These couplings are suitable for applications requiring high torque to size ratio, as well as high speeds. Lovejoy gear couplings with continuous and flanged sleeves are ideal for applications involving extended distances between shaft ends, mill motors and limited end floats. Known for their durability, Lovejoy nylon sleeve gear couplings are best suited for light industrial applications such as generator sets, motor pumps, and motor / generator sets.
Lovejoy gear couplings transmit torque via hubs with crowned gear teeth that are in permanent mesh with the straight gear teeth of sleeves. This unique design provides the highest torque transmission for the smallest size. Lovejoy gear couplings run at high speeds, conform to the AGMA bolting pattern and compensate for angular, radial and axial shaft misalignments.
Continuous sleeve gear couplings (C, CMM, CSPCR, CCS & CSHP Types):
Flanged sleeve gear couplings (F, FRR, FARR, FMM, FFS, FSPCR, FSL FSLX, FSHP, FSHPB, FVX, FLEF, FLA, FLAFR, FLAMM, FLHD, FLHDFR, FA, FAFR & FAMM Types):
Nylon sleeve gear couplings (Nyflex, Mite & Dentex Types):

Getting the right coupling is quite important, as it lowers the stress on pumps and motors and also decreases the chances of flexibility or misalignment.
Non flanged couplings are used with two non coaxial shafts. Oldham couplings, universal couplings and cushion couplings are examples of non-flanged couplings.
Lovejoy gear couplings are available in two types - flanged sleeve and continuous sleeve. Flanged gear couplings consist of short sleeves enclosed by a perpendicular flange, in which one sleeve is set on each pole so that two flanges line up face to face. Continuous sleeve gear couplings have shaft ends coupled together and adjoined against one another, which is then enveloped by a sleeve.
Lovejoy gear couplings are manufactured to transfer torque between two shafts that are not properly positioned. These gear couplings attach the drive motor to the gearbox in hoist mechanisms, and can also connect the gearbox directly to small wire rope drums using a flanged half.
