Product Description

This Lovejoy 1000 series grid coupling assembly spacer hub hardware set replaces worn hardware on existing Lovejoy 1000 series grid couplings and is made of lightweight, die-cast aluminum to resist corrosion and tarnishing. Grid couplings, a type of flexible coupling, use a flexible grid that fits into slotted hubs to transmit torque and offset rotational misalignment. The serpentine shape of the grid absorbs impact energy, reduces vibration, and transmits torque from one hub to the other through the grid. This grid is suitable for horizontal-style coupling designs and uses imperial unit measurements for industry consistency and interchangeability. It has an operating temperature range of -40 to 250 degrees F (-40 to 121 degrees C). Together with the other component parts of the coupling assembly, the grid supports constant angular misalignments up to 0.25 degrees. It meets International Organization for Standardization (ISO) 9001 for quality assurance. Lovejoy 1000 series grid couplings are suitable for use in various industrial power transmission applications such as pumps, mixers, crushers, fans, compressors, conveyors, pulverizers, and other equipment found in the steel, pulp, paper, mining, aggregate, and construction industries.

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.
