DMB type key connection single type elastic diaphragm coupling(Q/YP 22004X-2018)

DMB type key connection single type elastic diaphragm coupling(Q/YP 22004X-2018) is an advanced transmission device that integrates high precision and toughness. It stably couples two wheel hubs with a single metal diaphragm group through a precise key connection structure, designed to achieve efficient torque transmission while accurately compensating for comprehensive misalignment deviations in axial, radial, and angular directions. Compared with Snake Spring Coupling, which focuses on heavy load buffering, this product achieves an extremely long service life in an environment without lubrication due to its all metal stainless steel or alloy steel material. It also demonstrates excellent torsional rigidity and corrosion resistance. Its highest nominal torque can be carried up to 8100 kN · m, which can perfectly adapt to complex working conditions with strict requirements for operational accuracy from aerospace, power energy to petrochemicals.

Its compact and lightweight structural design significantly reduces rotational inertia, and effectively absorbs impacts and vibrations during operation by utilizing the elastic properties of the diaphragm. While ensuring smooth and quiet operation of the system, it greatly reduces the wear and maintenance frequency of key power equipment.
