What is a spider coupler?

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.

How do you replace a coupler on a log splitter?

Instructions

  1. Disconnect the spark plug wire. Disconnect the spark wire so there’s no chance that the log splitter engine could accidentally start.
  2. Remove the hydraulic pump.
  3. Remove the flexible pump coupler.
  4. Install the new flexible pump coupler.
  5. Reconnect the spark plug wire.
  6. Test the hydraulic pump operation.

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 a rubber spider coupling?

Rubber and Polyurethane Spiders are an Essential Component of Jaw Couplings. A jaw coupling is a power transmission coupling that can also be used in motion control applications, for example, a motor. It connects two shafts while minimizing vibrations and compensating for any parallel, angular, and axial misalignment.

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 component of the jaw and spider coupling should be replaced periodically?

Two hubs, and an elastomeric spider or insert. Jaw couplings are fail-safe. While you should periodically check your jaw coupling spiders for wear and replace them inevitably, someone will forget to check or service a jaw coupling and the spider will wear out or fail.

What is a coupling insert?

Flexible insert couplings are mechanical devices that feature metal hubs and a flexible polyurethane shaft coupling insert. This style of coupling connects two inflexible rotating shafts and transmits power from one shaft to the other while accommodating any misalignment.

Who makes Lovejoy couplings?

How do I know my 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 many types of coupler are there?

However there are two main types of couplings (Fig 1) which are (i) rigid couplings, and (ii) flexible couplings. Rigid couplings are used for shafts having no misalignment. Since these couplings cannot absorb any misalignment the shafts to be connected by a rigid coupling must have good lateral and angular alignment.
