This Lovejoy C Type accessory kit consists of the two O-ring seals and snap rings required for a specific Sier-Bath continuous sleeve gear coupling (not included), and is suitable for assembling that coupling. One of the Buna-n O-ring seals is located between the sleeve and each hub to retain the coupling lubricant. Steel reinforcement of the O-ring inner lip helps make the seal more durable, and the O-ring seal has an operating temperature range of -40 to 100 degrees C (-40 to 212 degrees F). Hardened spring steel snap rings at each end of the sleeve hold the seals and hubs in place and resist up to 100,000 pounds of end thrust. Gear couplings, a type of flexible coupling, use gear teeth on hubs and sleeves to transmit torque and offset rotational misalignment, and are suitable for use in applications involving extended distances between shaft ends, such as metal rolling mills and paper mills.
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 other transmission and mechanical power products. The company, founded in 1900, is headquartered in Downers Grove, IL.
