Magnetic Coupling Non-contact High Torque Permanent Magnet Disc Coupling Planar Magnetic Plate Connector DC
Disc type magnetic couplings consist of two opposing discs with powerful rare earth magnets. The torque applied to one disc is transferred through an air gap to the other disc. Because of its simple flat design, you can have angular misalignment of up to 3º or parallel misalignment up to ¼” and still transmit nearly full rotational torque. You could also fabricate an inexpensive flat barrier to separate the atmospheres or fluids surrounding the two discs. This is our simplest and most versatile coupling.

Introduce Magnetic Disk Couplings.
Torque may be transferred without touch using magnetic couplings. To prevent corrosive, poisonous, or combustible substances from leaking into the atmosphere, they are often utilized in pumps for seal-less applications. Simple Concept: Opposite Poles Attract.

Magnetic disk couplings transfer torque from one magnetic hub to another via this attraction. Torque is transferred magnetically to the other magnetic hub by driving the first magnetic hub. The inner magnetic hub may be completely isolated from the outer magnetic hub by doing this via the air or a non-magnetic containment barrier like stainless steel or fiberglass. No contacting components exist.

Disc-type couplings have two opposed discs that are strongly magnetized using rare earth elements. Through an air gap, the second disc receives the torque given to the first disc. Due to its straightforward flat design, you can transfer virtually all of the rotating torque with angular misalignment up to 3º and parallel misalignment up to ¼”. You may also create a low-cost flat barrier to divide the fluids or atmospheres around the two discs. Our most straightforward and adaptable connection is this one.

Disadvantages of magnetic disk couplings

Since the magnetic disk couplings rely on suction to transmit torque, the bracket that fixes the gear needs to withstand the suction and may deform over time.Therefore, for the protection of fixed brackets, magnetic shaft couplings will be better.

Ameridrives Disc and Diaphragm Couplings: Characteristics and Benefits
In the world of high-performance machinery, disc, and diaphragm shaft couplings play a crucial role in transmitting torque and accommodating misalignment between equipment shafts. These non-lubricated couplings rely on the flexure of metallic membranes to handle angular and axial misalignment, ensuring efficient operation and longevity of the machinery. In this article, we will discuss the two principal types of couplings, their characteristics, benefits, and considerations, with a specific focus on Ameriflex diaphragm coupling.

disc couplings utilize the flexure of metallic discs to transmit torque. These couplings consist of thin, metallic rings stacked together, typically in a circular, hex, or scalloped shape. The driving bolts pull the driven bolts, with the disc material at a constant bolt circle, enabling torque transmission. To maintain the integrity of the coupling, the discs are clamped together with washers using bolts attached alternately to the driving and driven flanges. Disk High Torque Magnetic Coupling for Gearbox

Disc Couplings Misalignment

While disc couplings offer a long service life, they are not infinite-life couplings. During misalignment, the flexing of the discs can lead to surface rubbing between adjacent discs, resulting in fretting and wear. This fretting can create a favorable environment for corrosion to attack the disc material, leading to corrosion fatigue and potential fatigue failure. However, proper design considerations, such as disc shape (e.g., scalloping) and thickness, can help mitigate fretting corrosion to some extent.

To enhance the finite coupling life of disc couplings, some manufacturers apply coatings to the discs. However, studies have shown that most coatings have a negative impact on the endurance strength of the base material. Therefore, it becomes crucial to carefully evaluate the impact of coatings on the overall performance and durability of the coupling.  Pump Motor Magnetic Disc Couplings
