What is a Lovejoy coupling?

What is a Lovejoy coupling?

The Jaw Type couplings from Lovejoy are offered in the industry’s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications.

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.

How do I choose a Lovejoy coupling?

Primary factors that will affect the type and size of coupling used for an application include, but are not limited to: horsepower, torque, speed (RPM), shaft sizes, environment conditions, type of prime mover, load characteristics of the driven equipment, space limitations and maintenance and installation requirements …

What is a coupling used for?

A coupling is a mechanical element part that connects two shafts together to accurately transmit the power from the drive side to the driven side while absorbing the mounting error (misalignment), etc. of the two shafts.

How do you pick a jaw coupling?

How to select couplings

  1. Select the coupling type suitable to the intended usage.
  2. Select the material of the coupling in line with the environment of usage.
  3. Select the coupling size fitted to the torque, space and bore size required.
  4. Select the fastening method between the shafts and the coupling.

How does a jaw coupling work?

In jaw couplings, the element is loaded in compression between the jaws of mating hubs. These jaws operate in the same plane, with the driving hub jaws pushing toward the driven hub jaws. Legs of the elastomeric spider transmit and cushion the force between the driving and driven jaws by being compressed between them.

What is a Curvic coupling?

Curvic Couplings In essence, the curvic coupling is a ring of precision ground face splines that are meshed after index. The splines, or radial teeth, are ground in such a manner that on one member the sides of the teeth surfaces that meshed are convex and on the other member the sides are concave.

What is a spider coupling?

The spider coupling concept gives a reliable, smooth power transmission without torsional oscillation / vibration and so protects the connected machinery. The puncture proof spider coupling can be loaded extremely high since the elastic elements are submitted to compression and not to bending moments of force.

What is L type coupling?

Industry’s standard shaft coupling. Accommodates for angular and parallel shaft misalignment. Fail-safe (will still perform if elastomeric “spider” fails) No metal to metal contact.

How do I choose a coupling?
