Curved Jaw Couplings
You’ve seen them all over on shaft-to-shaft applications – maybe even in your local hardware store. The addition of our Curved Jaw Coupling line has proven that you can rely on Hayes for all your couplings needs. Replacing existing couplings (of similar design) with the Hayes Curved Jaw Coupling may save you some $$
This three-piece curved jaw coupling design was specifically designed to reduce the edge pressure of the driving lugs to the insert. These curved jaw couplings are perfectly interchangeable with other German and Italian designs of the same type. Hubs are made in both aluminum, and steel.
The elements, or spiders, are made from variable durometer urethane. Available in 10 sizes, bores to 110mm (4.33). These couplings are great for electric motor driven pumps, gearboxes, conveyors, as well as applications with reversing loads, due to compression nature of the design. These curved jaw couplings are torsionally flexible and designed to dampen operational vibrations and shock loading.
With the teeth of the spider being crowed, to avoid edge pressure, it allows for greater shaft misalignment’s over couplings of a similar design (Straight Jaw). With the concave tooth design this coupling is subject to a pressure only load as compared to other straight jaw couplings, which are prone to a bending stress as well. Due to this difference in driving ability, the curved jaw coupling will withstand considerably higher loads.
