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 Spider in coupling?

Jaw couplings are composed of three parts: two metallic hubs and an elastomer insert called an element, but commonly referred to as a “spider”. The three parts press fit together with a jaw from each hub fitted alternately with the lobes of the spider.

What’s a love joy 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 does a Lovejoy Coupling work?

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.

How do you calculate coupling size?

Calculating The Inside Diameter With A Digital Caliper

  1. Place the inside tips of the caliper on the inside of the bowl (coupling)
  2. Expand the tips of the caliper until they’re fully extended to the bowl size.
  3. This will give you the correct size of the bowl needed.
  4. 1.75 is equivalent to a 1 3/4 size bowl.

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.

What is a jaw coupling spider?

Jaw and Spider Couplings. Jaw & Spider (or Jaw-Type) couplings are a common type of shaft coupling in the industry. They are designed to transmit torque and rotation between two shafts, accept shaft misalignment, and help protect components from damage by damping shock and vibrations.

How do you determine coupling size?

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.

How do you design a coupling?

Design Documents (Shaft Couplings)

  1. Design Procedure. Calculate the Design Torque.
  2. Calculate the Design Torque. Select the overload factor Ko from [Table 1] and obtain the design torque.
  3. Select the Size.
  4. Check the Maximum Shaft Hole Diameter and Maximum Rotation Speed.
  5. Conclusion.

What is the maximum torque of a Lovejoy jaw coupling?

Lovejoy’s Jaw Type couplings are available in 24 sizes from a minimum torque rating of 3.5 in–lbs (0.4 Nm) to a maximum torque rating of 170,004 in–lbs (19209 Nm) and a bore range of .125 inches (4.45mm) to 7 inches (178mm). Lovejoy’s standard bore program covers AGMA, SAE, and DIN bore/keyway and spline bore combinations.

What kind of iron is Lovejoy line jaw coupling made out of?

Lovejoy L line jaw coupling hubs through size L150 are manufactured out of sintered iron. This is a well proven technology that has been used by Lovejoy for decades and can be re-bored locally similar to other standard coupling hub materials.

What kind of couplings do Lovejoy cars use?

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 are spiders key to jaw coupling performance?

Spiders are Key to Jaw Coupling Performance. One of the most widely applied types of flexible couplings is an elastomeric design known as the jaw coupling. This design is characterised by two hubs, each having two or more thick, stubby protrusions around their perimeters, called jaws, pointing toward the opposing hub.
