About Lovejoy 03980 Size FA 3.5E Sleeve Component For

This Lovejoy FA Type flanged sleeve is made of low-alloy steel, comes with an O-ring seal, and is intended for use as a component of a Sier-Bath flanged sleeve gear coupling (sold separately). This sleeve is made of American Iron and Steel Institute (AISI) 4140 alloy steel for strength and durability and the precision location of its mounting bolt holes maintains concentricity when bolting sleeves together. A Buna-n O-ring seal is located between the sleeve and the flex 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 Celsius (-40 to 212 degrees Fahrenheit). The sleeve teeth mesh with the hub teeth to allow for angular misalignment of up to 1.5 degrees per hub. The sleeve also accommodates parallel and axial misalignment of the attached shafts. 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.
