Jaw coupling hubs and spiders connect two drive shafts to transfer power while absorbing shock and vibration and accommodating misalignment. This helps to protect the components from damage. Jaw coupling assemblies consist of two hubs and a spider insert with a jaw from each hub fitted alternately with the lobes of the spider.

Apr 28, 2015· The disc coupling solution reduced the maintenance nightmare, and the plant has been experiencing success for more than a year with the original installation. Plant management approved the proposal to convert all gear couplings on 24 coal pulverizers to Lovejoy disc couplings, based upon the proven benefits and demonstrated cost savings.

Victaulic's patented Installation-Ready™ couplings provide fast, easy pipe connections, and reduce the number of loose parts to drop or misplace. The single-unit design allows an installer to assemble the coupling or fitting simply by inserting it onto the grooved end of a pipe and tightening the nuts.

Jaw Coupling Spiders help to dampen shock between coupling hubs and accommodate small amounts of angular, parallel, and axial misalignment. A complete assembly requires one .

TB Wood's engineers recommended switching to a Form-Flex floating shaft coupling to mount between the drive motor and the fan. The custom coupling was modified with limited end float features to keep the sleeve bearing motor rotor from being damaged.

Axial misalignment: This is the variation in the distance between the machinery shafts in relation to the neutral length of the coupling. Angular misalignment: This is the effective angle between the two machinery shafts and is usually quantified by measuring the angle between the center lines of the shafts if they were extended to intersect.

The coupling transmit torque and accommodate both angular, offset and axial misalignment between shafts, with a coupling comprised of shaft mounted hubs connected through flexible disc packs with spacer or sleeve assemblies.
