Lovejoy 00216 Size F 4 Sier-Bath Flanged Sleeve Features

• Flex hub component of a Sier-Bath flanged sleeve gear coupling

• AISI 1045 steel for strength and durability

• Engages with another flex hub ('F' flex-flex) for parallel and angular misalignment

• Single engagement with rigid hub ('FFR' flex-rigid) for angular misalignment only; suitable for floating shaft applications

• Crowned teeth for larger contact area with sleeve and lower stress under misaligned conditions

About Lovejoy 00216 Size F 4 Sier-Bath Flanged Sleeve

This Lovejoy F Type flex hub is made of steel and is intended for use as a component of a Sier-Bath flanged sleeve gear coupling (sold separately). This hub comes either with a rough stock bore or uses an interference fit, with or without a keyway, for a secure attachment to the shaft. It is made of American Iron and Steel Institute (AISI) 1045 steel for strength and durability. The hub teeth are fully crowned for a larger contact area with the sleeve teeth and lower stress under misaligned conditions. When mated with another flex hub, the coupling allows for angular misalignment of up to 1.5 degrees per hub and accommodates parallel and axial misalignment of the attached shafts. When mated with a rigid hub, the coupling allows for angular misalignment only and is suitable for floating shaft applications. 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.
