Oldham couplings are mechanical devices designed to connect two misaligned shafts, transmitting rotation between them. Featuring a middle disc that compensates for misalignment between the connected shafts, these couplings are known for their ability to absorb parallel and angular misalignments while transmitting torque. Oldham couplings are favored for their affordability and versatility across various applications.
Oldham couplings are commonly employed in machinery where precision alignment isn't possible or cost-effective. Their primary applications include:
Comprising two hubs and a central disc, Oldham couplings allow the connected shafts to move independently. The disc, slotted to engage with grooves on each hub, slides to accommodate misalignment. This design ensures smooth torque transmission across misaligned shafts without significant efficiency loss or wear.
Oldham couplings offer several benefits, including:
Selection criteria for Oldham couplings involve considering the application's torque requirements, the degree of shaft misalignment, and environmental factors. Material choices for hubs and discs vary, with options like aluminum for lightweight applications and stainless steel for higher torque or corrosive environments. Maintenance needs, particularly disc replacement due to wear, also influence the choice of coupling.
