Lovejoy Motion Control Couplings

The process of selecting the appropriate Motion Control coupling commences with the choice of the coupling design that best suits the specific application demands. Lovejoy's Motion Control Coupling Quick Reference Chart, found in the Motion Control catalog, offers a systematic approach for evaluating the performance attributes of various couplings, including Beam, Bellows, Mini-Disc, Oldham, Mini-Soft, Curved Jaw, and Mini-Jaw. These couplings are comprehensively compared in essential categories such as material, torque, torsional stiffness, bore capacity, maximum RPM, misalignment tolerance, maximum temperature, and moment of inertia.

Once a design is picked, the next step is determining the suitable size based on that design's capabilities. For the Beam, Bellows, and Mini-Disc designs, which feature single-piece construction, only one part requires selection. In contrast, the GS curved jaw, Oldham, Mini Soft, and Mini Jaw designs comprise three parts, including two hubs and an insert. The hub selection is dictated by whether the driver and driven shafts share the same diameter or differ in size.

The following information is essential when choosing a motion control coupling:

• The horsepower (HP) and revolutions per minute (RPM) of the driver.

• The shaft size of both the driver and driven components.

• The specific application requirements.

• Environmental factors, such as extreme temperatures, corrosive conditions, and space constraints.

• Spatial limitations, encompassing factors like the maximum outside diameter and overall length of the coupling
