Frequently Asked Questions (FAQs)

1. Is Spider coupling flexible?

These spider / jaw mechanical power transmission couplings are torsionally flexible shaft couplings, the operating characteristics of which are two hubs with concave claws, transmitting the torque by meshing with an elastic involute gear ring.

2. 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.

3. Why are spiders used in couplings?

Just as coupling designs differ to satisfy different application criteria, so do the spiders in jaw 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.

4. What is a flexible coupling used for?

The purpose of a flexible coupling is to transmit torque from one piece of rotating equipment to another, while accepting at the same time a small amount of misalignment. Flexible coupling misalignment is expressed, as an order of magnitude, in thousandths of an inch.
