Lovejoy L190 Standard Jaw Coupling Hub Iron 1 3/4 In Bore w 3/8 x 3/16 In Kw
This Lovejoy standard jaw coupling hub replaces hubs on Lovejoy L type jaw style flexible couplings and is made of cast iron for non-corrosive applications where strength and heat dissipation are factors and weight is not.
This hub transfers shock and misalignment from the shaft to the center element of the coupling assembly for reduced wear on the shaft assembly.
Lovejoy jaw style couplings are suitable for use in various industrial power transmission applications such as compressors, blowers, pumps, conveyors, mixers, and gear boxes, among others.
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.
I only need to put 14 more word in here, Im so close I can taste it.
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.
