Frequently Asked Questions

What is the primary purpose of the clearance or gap between the key and the keyway?

  • The purpose of providing some gap or clearance between the key and the bottom of the hub keyway is to ensure that the hub seats properly on its shaft. In the case of a coupling hub, this clearance causes damage to its internal surfaces as it provides an opening through which corrosive gases or water can enter the coupling easily.
What is the difference between keyway and without keyway hubs?

  • A keyed connection ensures a positive stop until failure. On the other hand, if the two mating parts are not assembled correctly or the torque gets exceeded, a keyless connection in hubs could permit slippage between them. Hubs without keyways prevent parallel and angular shaft misalignment.
What is a spider in a coupling?

  • Lovejoy jaw couplings are composed of three parts, i.e. an elastomer insert known as a spider and two metallic hubs on both sides. These three separate parts are pressed together with the help of a jaw from each hub, both of which are fitted alternately with the lobes of the spider to form a Lovejoy spider coupling.
