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...

Using advanced design techniques, implementation of Finite Element Analysis, and extensive testing of materials, Lovejoy has developed an innovative disc pack profile design revolutionary to traditional disc pack designs found in the market. This disc pack, which can accommodate 1/2° to 1-1/2° of angular misalignment and is used in all Lovejoy disc coupling products. The design and manufacture of Lovejoy disc couplings is integrated into a certified Quality System according to ISO-9001 to fulfill the high quality requirements of Lovejoy customers. Lovejoy couplings are offered in a variety...

Lovejoy Disc Coupling Overview Industrial SU Type The SU Type coupling has a single flex plane with two hubs and a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are often combined with a shaft to make a floating shaft coupling. The shaft can be hollow for long light weight floating shaft couplings. This is the standard coupling type that includes two hubs, a stock length spacer designed to meet industry standard lengths, and two unitized disc packs. The coupling has two flex planes, one at each disc pack, allowing this coupling to accommodate...

The following is a sample application used to illustrate the standard process for selecting a Lovejoy Disc coupling. Any resemblance to any existing company’s application is neither intentional nor meant to resemble that company’s actual application. handle the selection torque calculated in step 2. The SX202-6, however, will not support the 92mm shaft size. The next larger size coupling, the SX228-6, will support the 92mm shaft size and the shaft separation dimension (BSE) is 6.88 inches, very close to the application’s desired 7 inch separation. The SX228-6 is rated at 62,000 in-lbs which...

Lovejoy Coupling Solutions Disc Application Service Factors Selection Data Selection Procedure 1. Select the coupling type. 2. Select the driven machine service factor SFa from Table 1. 3. Select the driving machine service factor SFd from Table 2. Care should be taken when the driving machine is other than a standard electric motor or turbine. Some engines will impose extra fluctuations on the drive system and allowance should be made accordingly. Please refer to Table 2. A torsional coupling may be required for diesel drives. The two service factors SFa and SFd must be added resulting in...

Lovejoy Coupling Solutions SU-6 Type Industrial Coupling The SU Type coupling is a 6 bolt single flex plane coupling which consists of two hubs and one disc pack kit. It is only suitable for the specified axial and angular misalignment and does not accommodate parallel misalignment. It is often combined with solid shafts to make floating shaft couplings. See Page D-28 for a picture of an SXFS Type floating shaft coupling. Features ■ Unitized disc pack ■ Infinite life when properly aligned ■ Torsionally rigid without any back lash ■ No need for lubrication or maintenance ■ No wearing parts...

Lovejoy Coupling Solutions SX-6 Type Industrial Coupling The SX-6 Type is a standard coupling with two hubs, a spacer, and two disc pack kits. The coupling has two flex planes (one at each disc pack) so it can accommodate parallel misalignment by the angular misalignment in each disc pack. This configuration will also accommodate axial misalignment within the specified limits. Features ■ Unitized disc pack ■ Infinite life when properly sized and aligned ■ Accommodates angular, axial, and parallel misalignment ■ Torsionally rigid without any back lash ■ No need for lubrication or maintenance...
