2 Overview Jaw Type Couplings USA Standard Elastomer-in-Compression The Jaw Type couplings from Lovejoy are offered in the industry s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications. Other features and benefits include: Fail-safe will still perform if elastomer fails. No metal to metal contact. Resistant to oil, dirt, sand, moisture and grease. More than 850,000 combinations of bore sizes. Most types available from stock in 24 hours. L COUPLING Applications include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers, and conveyors. Lovejoy s Jaw Type couplings are available in 24 sizes from a minimum torque rating of 3.5 in lbs to a maximum torque rating of 170,004 in lbs and a bore range of.125 inches to 7 inches. Lovejoy s standard bore program covers AGMA, SAE, and DIN bore/keyway and spline bore combinations. LC COUPLING The Lovejoy Jaw Type coupling is available in a variety of metal hub and insert materials. Hubs are offered in sintered metal, aluminum, bronze, steel, stainless steel, and ductile iron. L Type This coupling offers standard shaft-to-shaft connection for general industrial duty applications. Standard L type coupling hub materials are either sintered iron (L035 - L150) or cast iron (L190 - L276). LC Type This is the basic L coupling, except the insert is a snap wrap elastomer with retaining collar. Designed for easy elastomer replacement without disturbing the hubs, this coupling type is suited for applications over 1750 RPM. AL Type The aluminum construction means this coupling is light weight with low overhung load and low inertia. The AL type also offers excellent resistance to atmospheric conditions, so it is perfect for corrosive environment applications. SS Type New SS type stainless steel hubs available for applications needing maximum protection against harsh environmental conditions. Sizes SS075-SS150 available from stock. Other sizes available on request. RRS Type The center drop out section of this coupling provides proper shaft separation while also allowing easy elastomer installation without disturbing the hubs or requiring realignment of shafts. Designed for the pump industry, it accommodates American and European industry standard pump/motor shaft separations. The drop out spacer is made of glass reinforced plastic, cast iron or aluminum. SW Type This coupling is the standard L Type with a snap wrap elastomer with retaining ring. It is well suited for standard shaft-to-shaft connection in general industrial purpose applications under 1750 RPM. C & H Types These couplings provide standard shaft-to-shaft connection for medium (C) and heavy (H) duty range applications. The standard C coupling hub is made of cast iron, while the H is constructed of ductile iron. -2 AL COUPLING SS COUPLING RRS COUPLING SW COUPLING C & H COUPLINGS The new Jaw In-Shear coupling is presented in the next section of this catalog, labeled JIS on the page tabs

3 Overview Elastomers-in-Compression Lovejoy offers four types of elastomer designs to allow for additional flexibility in addressing specific application requirements. One piece designs are used in the L and AL models (referred to as spiders) and multiple part load cushions are used in the C and H model couplings. The load cushions are in sets of 6 to 14 pieces depending on coupling size. Solid Center Spider The solid center design is the most commonly used in general power transmission applications when the shafts of the driver and driven can be kept separate by a standard gap. Open Center Spider The open center spider design allows the shafts of the driver and driven to be positioned within a short distance. Open center spiders offer shaft positioning flexibility but have a lower maximum RPM capability. (1750 RPM max. for NBR, 3600 RPM max. for Urethane/Hytrel.) Cushions The cushion design is available exclusively for the Lovejoy Types C and H jaw couplings. The load cushions are held in place radially by a steel collar which is attached to one of the hubs. This design allows for easy installation and removal of the load cushions. The cushion design has the same engineering purpose as the spider designs but is more effective in the heavy duty applications that Types C and H couplings address. Snap Wrap Flexible Spider The snap wrap flexible spider design allows the spider section of the coupling to be easily installed or removed without disturbing the coupling hubs. This design also allows for close shaft separations all the way up to the hubs maximum bore, which is not possible with open center spiders. Maximum RPM is 1750 with retaining ring, but if used in LC Type (with collar) the normal RPM rating of the coupling size applies. This style is available in NBR and Urethane only, and in limited sizes. NOTE: Complete technical data for the new Jaw In-Shear elastomer is contained in the next section of this catalog, labeled JIS on the page tabs. Spider Materials SOX (NBR) Rubber Nitrile Butadiene (Buna N) Rubber, a highly flexible insert material that is oil resistant, is our standard elastomer. It resembles natural rubber in resilience and elasticity, and operates effectively in temperature ranges of - 40º to + 212º F (-40º to +100ºC). (Also applies to SXB Cushions.) Urethane Urethane has 1.5 times greater torque capability than NBR and offers good resistance to oil and chemicals. However, this material provides less dampening effect and operates at a temperature range of -30º to +160º F (-34º to +71ºC). Hytrel Hytrel is a flexible elastomer designed for high torque and high temperature operations. Hytrel can operate in temperatures of -60º to +250º F (-51º to +121ºC) and has an excellent resistance to oil and chemicals. It is best used in continuous load applications rather than cyclic or on/off service. Bronze Bronze is a rigid, porous, oil-impregnated metal insert exclusively for low speed (max. 250 RPM) applications requiring high torque capabilities. Bronze performance is not affected by water, oil, dirt, or extreme temperatures operates in temperatures of -40º to +450º F (-40º to +232º C).!

Failure to follow the instructions and precautions can result in severe injury or death. -3

4 Selection Process Jaw Type Coupling Selection Process The selection process for determining the proper jaw coupling size and elastomer requires using the charts shown on the following pages. There are three components to be selected, two hubs and one elastomer. When the shaft size of the driver and driven of the application are of the same diameter, the hubs selected will be the same. When shaft diameters differ, hubs selected will differ accordingly. Information necessary before a coupling can be selected: HP (or KW) and RPM or Torque of driver Shaft sizes of driver and driven equipment and corresponding keyways Application description Environmental conditions (i.e. extreme temperature, corrosive conditions, space limitations) List of Charts provided for Selection: Chart 1 Application Service Factors (pg. -6) Chart 2 Spider Performance Data (pg. -7) Chart 3 Coupling Nominal Rated Torque (pg. -7 or -20) Formulas: Nominal Torque = in-lb = Nm = (HP x 63025) RPM (KW x 9550) RPM Design Torque = Nominal Torque x Application Service Factor Steps In Selecting A Jaw Coupling Step 1: Determine the Nominal Torque of your application by using the following formula: Nominal Torque = in-lb = (HP x 63025) RPM Nm = (KW x 9550) RPM Step 2: Using the Application Service Factors Chart 1 (pg. -6) select the service factor which best corresponds to your application. Step 3: Calculate the Design Torque of your application by multiplying the Nominal Torque calculated in Step 1 by the Application Service Factor determined in Step 2. Design Torque = Nominal Torque x Application Service Factor Step 4: Using the Spider Performance Data Chart 2 (pg. -7), select the elastomer material which best corresponds to your application. Step 5: Using the Coupling Nominal Rated Torque Chart 3 (pg. -7), locate the appropriate elastomer material column for the elastomer selected in Step 4. Scan down this column to the first entry where the Torque Value in the appropriate column is greater than or equal to the Design Torque calculated in Step 3. Once this value is located, refer to the corresponding coupling size in the first column of the Coupling Nominal Rated Torque Chart 3 (pg. -7). Refer to the maximum RPM value (pg. -20) for this elastomer torque capability to ensure that the application requirements are met. If the requirement is not satisfied at this point, another type of coupling may be required for the application. Please consult our Lovejoy application engineers. Step 6: Compare the application driver/driven shaft sizes to the maximum bore size available on the coupling selected. If coupling bore size is not large enough for the shaft diameter, select the next largest coupling that will accommodate the driver/driven shaft diameters. Refer to Chart 3 (pg. -7). Step 7: Using the Item (UPC) Number Selection charts (pgs. -9 and -10), find the appropriate Bore and Keyway sizes required and locate the Lovejoy Item (UPC) number. -4

5 Selection Process Selection Example A coupling is needed to connect a 20 HP standard electric motor rated at 1800 RPM to a rotary pump. The shaft size of the electric motor (driver) is 2.0 inches and the pump (driven) is 1.75 inches. There are no special environmental conditions and the general operating temperature is normal room temperature of 72º F. Less than 1º of misalignment is expected. Step 1: Determine the Nominal Torque: Nominal Torque = (HP x 63025) RPM = (20 x 63025) 1800 = in-lb Step 2: Using the Application Service Factor Chart 1 (pg. -6), select the service factor which best corresponds to your application. The Application Service Factor for an electric motor with standard torque driving a rotary pump is The value of 1.25 is found under the application category Pumps, Rotary, column: Electric Motor w/standard Torque in Chart 1. shaft sizes. Therefore, the proper coupling size for this application is a Lovejoy L190 with an NBR elastomer. Step 7: Using the Item (UPC) number Selection charts, locate the appropriate Lovejoy Item (UPC) numbers. The L Type Coupling Elastomer chart (pg. -8), and the L Type Coupling Inch Hubs chart (pg. -10), provides easy reference to the Lovejoy Item (UPC) numbers. Locate the L Type Couplings Elastomer chart (pg. -8). The elastomer is selected by scanning down the type column and locating the NBR (Solid) entry. Read across to the L190 column and locate the Lovejoy Item (UPC) number of This number should be prefixed with the Lovejoy Item (UPC) number of Locate the L Type Coupling Inch Hubs selection chart (pg. -10). Step 3: Calculate the Design Torque of your application: Design Torque = Nominal Torque x Application Service Factor = x 1.25 = in-lb Step 4: Using the Elastomer Performance Data Chart 2 (pg. -7), select the elastomer material which best corresponds to your application. Since there are no special environmental conditions, the operating temperature is 72ºF and less than 1º of angular misalignment is required, the NBR elastomer material is selected. The first bore size to be located is for the 2 inch shaft on the electric motor. Scan down the Bore/Keyway column to the 2 inch bore entry. Read across to the L190 column to locate the Lovejoy Item (UPC) number of This number should be prefixed with the Lovejoy Item (UPC) number of The second bore size to be located is for the 1.75 inch shaft on the pump. Scan down the Bore/Keyway column to the 1 3 / 4 inch bore entry. Read across to the L190 column to locate the Lovejoy Item (UPC) number of This number should be prefixed with the Lovejoy Item (UPC) number of Step 5: Using the Coupling Nominal Rated Torque Chart 3 (pg. -7), the NBR elastomer column is used to determine the proper coupling size. Scanning down the NBR column, the first entry to accommodate the Design Torque value of in-lb is the size L150 with a nominal torque rating of 1,240 in-lb. Referring to page -20, the maximum RPM of 1800 on the electric motor of the application does not exceed the 5000 RPM maximum allowed for the L150 size coupling with an NBR elastomer. Step 6: Compare the application driver/driven shaft size to the maximum bore available in the coupling selected (pg. -7). The electric motor (driver) of this application has a shaft size of 2.0 inches and the pump (driven) has a shaft size of 1.75 inches. The L150 coupling has a maximum bore less than the driver shaft size. Continuing down the Maximum Bore column, in Chart 3 (pg. -7), the L190 size is found to have a maximum bore size of and is able to accommodate the driver/driven -5
