This Lovejoy C Type rigid hub is made of steel and is intended for use as a component of a Sier-Bath continuous sleeve gear coupling (not included).
This hub uses an interference fit and a keyway for a secure attachment to the shaft and is made of American Iron and Steel Institute (AISI) 1045 steel for strength and durability.
The hub teeth are fully crowned for larger contact area with the sleeve teeth and lower stress under misaligned conditions, which allows for angular misalignment of up to 1.5 degrees when mated to a flex hub.
The hub 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.
