Spider Performance

Spider Performance

Nitrile Butadiene (Buna N) Rubber is a flexible elastomer material that is oil resistant, resembles natural rubber in resilience and elasticity and operates effectively in temperature range of -40° to 212° F (-40° to 100° C). Good resistance to oil. Standard elastomer. (Also applies to SXB Cushions.)

Elastomers in Compression

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 commonly used design when shafts of the driver and driven equipment can be kept separate by a standard gap Open Center Spider The open center design allows for 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 RPM capacity (1,750 RPM maximum for NBR, 3,600 maximum for Urethane/Hytrel®) Cushions Used exclusively for the C and H Type couplings Load cushions are held in place radially by a steel collar which is attached to one of the hubs Snap Wrap Flexible Spider Design allows for easy removal of the spider without moving the hubs Allows for close shaft separation all the way up to the hubs maximum bore Maximum RPM is 1,750 RPM with the retaining ring, but if used with the LC Type (with collar) the normal RPM rating of the coupling applies Style is available in NBR and Urethane only, and in limited sizes

NBR standard shore hardness is 80A ±5A – Except L035=60A. Other softer or harder designs are available in NBR material; consult Lovejoy.

Lovejoy L150 Solid Type Jaw Coupling SOX/NBR Rubber Spider

 

This Lovejoy solid type jaw coupling elastomer spider replaces solid center elastomers on Lovejoy jaw style flexible coupling assemblies and is made of Nitrile rubber for transferring and absorbing shock load.

The solid center design keeps the shafts of the driver and driven equipment separate by a standard gap. It can operate in temperatures ranging from -40 to 212 degrees F (-40 to 100 degrees C).

Lovejoy 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.
