How do I know what size my Lovejoy coupling is?
How do I know what size my Lovejoy coupling is?
Scan down the Bore/Keyway column to the 2 inch bore entry. Read across to the L190 column to locate the Lovejoy UPC number of 12303. This number should be prefixed with the Lovejoy UPC number of 685144. The second bore size to be located is for the 1.75 inch shaft on the pump.
What is the purpose of a Lovejoy coupling?
A flexible coupling connects two shafts, end-to-end in the same line, for two main purposes. The first is to transmit power (torque) from one shaft to the other, causing both to rotate in unison, at the same RPM. The second is to compensate for minor amounts of misalignment and random movement between the two shafts.
What is the purpose of a jaw coupling?
A jaw coupling is a type of general purpose power transmission coupling that also can be used in motion control (servo) applications. It is designed to transmit torque (by connecting two shafts) while damping system vibrations and accommodating misalignment, which protects other components from damage.

Where are Lovejoy couplings made?
Lovejoy’s world headquarters is located in Downers Grove, Illinois, USA. Our USA manufacturing operations are based in Downers Grove, Illinois, and South Haven, Michigan.
Why are spiders used in couplings?
The spider determines the coupling’s torque rating. It also affects the coupling’s response to vibration, temperature, chemicals, misalignment, and high speed, as well as its ease of installation. Selecting the right type of spider is just as important as selecting the right type and size of coupling.
What is a grid coupling?
Grid couplings are multi-piece mechanical shaft couplings used to transmit torque and rotation between shafts in mechanical power transmission assemblies. Their design allows them to accommodate the slight variations in alignment that occurs between connected shafts, while also absorbing shock loads.
What is a spider coupler?
Jaw-Type Couplings. Jaw-Type (Jaw & Spider) couplings feature two aluminum alloy hubs with protruding lugs known as “jaws” and an elastomer “spider” insert between the hubs. Aluminum keeps the jaw coupling lightweight and decreases the moment of inertia on start and stops.
Does Timken own Lovejoy?
NORTH CANTON, Ohio, July 8, 2016 /PRNewswire/ — The Timken Company (NYSE: TKR; www.timken.com), the world leader in tapered roller bearings, today announced that it has acquired Lovejoy, Inc., a manufacturer of premium industrial couplings and universal joints, for approximately $66 million.
Is Lovejoy a brand?
The Lovejoy brand is recognized around the world as the premier supplier of flexible shaft couplings and other power transmission components. The key to Lovejoy’s continued growth and success lies in the dedication to our customers.
How does an Oldham coupling work?
Oldham couplings transmit torque by mating the slots on the center disk to the drive tenons on the hubs. They accommodate angular and axial misalignment, and are especially useful in applications where parallel misalignment is present.
What is elastomeric coupling?
Elastomeric couplings are essentially a coupling made from a flexible elastic material that transmits torque. This specific type of coupling is designed to allow the elastic to wear out before the actual metal components wear out.
Which is the most accurate method of coupled shaft alignment?
For most of us, laser alignment is considered the most accurate and effective. But shaft alignment can be done with reverse dial indicator sets, or dial indicators and chain-type brackets, or a straightedge, feeler gauge, and an outside caliper.
What is a Bibby coupling?
The Coupling consists of two flanges or hubs specifically mounted on the drive and the driven shafts respectively. These hubs contain axial grooves cut on their circumference. The two couplings are joined or held together by means of a specially designed grid spring.
Are grid couplings flexible?
The Lovejoy Grid coupling reduces vibration by as much as 30%, and cushions shock loads to safeguard your driving and driven equipment. The flexible nature of the spring-like grid absorbs impact energy by spreading it out over time, thus reducing the magnitude of the peak loads.
Why spider is used in coupling?
Where are spider couplings used?
Spider / jaw mechanical power transmission couplings can be used for horizontal as well as for vertical shaft connections, for reversing, intermittent service and are electrically insulating.
What is a Lovejoy disc coupling?
Lovejoy disc couplings utilize unitized disc packs with 4, 6 or 8 bolt designs. While the 8 bolt design can transmit greater torque than the 6 or 4 bolt design, it is not able to accommodate as much angular misalignment. Lovejoy couplings can also be fitted with overload bushings to protect the disc pack during momentary torsional overloads.
Who makes Lovejoy coupling products?
Lovejoy, a business unit of The Timken Company (NYSE: TKR; www.timken.com), a world leader in engineered […] Lovejoy is pleased to announce it has redesigned its S-Flex Shear Type coupling product to make it the highest quality and longest lasting offering available in the marketplace. Lovejoy engineers […]
What is the backlash of a coupling?
If one half of a coupling is held rigid and the other half can be rotated a slight amount (with very little force), you have some amount of backlash. The freedom of movement, or looseness, is the backlash and may be expressed in degrees. Backlash is not the same as torsional stiffness.
