The Curved Jaw Design.

The Curved Jaw Design

Three piece design that is easy to assemble.
The curved jaw design incorporates both radial and axial curvature (crowning) to the elastomer (spider).
Hubs are offered in sintered iron, steel, aluminum, cast iron and nodular iron materials.
Three different urethane elastomers available.
No metal to metal contact and no lubrication required.
Fail safe design due to the jaw in compression design (continues to function after the elastomer fails).
The CJ series covers a torque range of 67 to 247,800 in-lbs.

Elastomer Characteristic.

Elastomer Characteristic

Four types of spiders are available for the CJ Series of couplings.
Urethane spiders provide high abrasion resistance and elasticity, along with good damping characteristics.
The spiders are offered in a variety of shore hard nesses, each providing a different level of torque capacity, damping, and chemical resistance.
The 92A shore insert (yellow in color) is the standard, offering excellent torque carrying capacity.
The 80A shore insert (blue) offers the best damping characteristics.
The 95/98A shore spider (red) offers higher torque than the standard 92 shore, but retains greater damping capacity compared to the 64D shore insert (green).
The 64D shore insert is offered for high humidity environments, higher temperatures, and offers the highest torque capacity.
The standard curved jaw spider design has a hole in the center to accommodate small between shaft end measurements.
The 80A, 92A, and 95/98A shore spiders have a temperature capacity of 212° F.
The 64D shore spider has a temperature capacity of 230° F.
The curved jaw spider’s urethane material also resists oil, dirt, sand, grease, moisture, many solvents, as well as atmospheric effects of ozone.

Application Types Requiring.

Application Types Requiring

High Torque Requirements.

Notes

Maximum bore may be achieved through the use of a shallow keyway.
Maximum bore refers to maximum straight bore with keyway allowed in hub.
Outside Diameter is equal to Dimension HD for B style aluminum sizes: 19, 24, and 28.
S = Solid hub with no bore
Spider Outside Diameter (Dimension A) is equal to Outside Diameter
The values regarding displacement are provided assuming normal operating conditions (i.e. temperature, torque with nominal rating of the coupling, speed/ RPM rating of the coupling, and misalignment).Careful installation (i.e. alignment) and periodic inspection should be provided to provide the optimum life of the coupling. Special consideration should be given as to the position of the shafts and the amount of axial movement the coupling will be exposed to.The more accurate the alignment of the coupling, will result in greater life of the elastomer. A coupling guard and rotating equipment safety procedures should always be followed.Please consult the Lovejoy web site at www.lovejoy-inc.com for assembly instructions of the curved jaw coupling.

Lovejoy CJ 55 Curved Jaw Coupling Urethane Spider 98 Shore A Red

This Lovejoy curved jaw coupling spider replaces the spiders on Lovejoy curved jaw style flexible spider coupling assemblies and is made of urethane for transferring and absorbing shock load.

This center element, also known as a spider, absorbs shock and misalignment within the coupling assembly for reduced wear on the shaft assembly.

Lovejoy curved jaw style couplings are a type of flexible coupling suitable for use in various industrial power transmission applications such as compressors, blowers, pumps, conveyors, mixers, and gear boxes, among others.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other.

Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts.

Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another.

Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Lovejoy manufactures flexible couplings, universal joints, variable speed drives and various other transmission and mechanical power products.

Their products meet the standards of the International Organization for Standardization (ISO), the Deutsches Institut für Normung (DIN), the American National Standards Institute (ANSI), the American Gear Manufacturers Association (AGMA), the Society of Automotive Engineers (SAE) and Japanese Industrial Standards (JIS) for quality assurance.

The company, founded in 1900, is based in Downers Grove, IL.
