Introduction to the Applications of Disc Couplings

Disc coupling is a metal flexible coupling that can transmit torque while compensating for displacement deviation. The core component is a disc group composed of stainless steel thin plates stacked together, which compensates for angular, lateral, and axial deviations by relying on the elastic deformation of the diaphragm

Classification of Disc coupling

Disc coupling are classified by material: the main material is aluminum alloy or 45 steel, and the diaphragm material is mainly stainless steel, such as 304 stainless steel, 316 stainless steel, SUS301CSP, CrNi stainless steel, etc. The most commonly used main material for KUDOSWORLD is 45 steel, and the most commonly used diaphragm material is 316 stainless steel.

Disc coupling can be classified into single Disc coupling and double Disc coupling according to the number of diaphragms. The main difference between single Disc coupling and double Disc coupling is that double Disc coupling can compensate for larger deviations. KUDOSWORLD recommends selecting the appropriate diaphragm coupling based on the application scenario.

Disc coupling can be classified according to their structural types, including those with intermediate shafts and stepped couplings.

Application of Diaphragm Coupling

Diaphragm coupling is a key component of power equipment, mainly used in large-scale petrochemical process pumps, boiler feed pumps, blowers, compressor units and other process power equipment in industries such as petrochemicals, printing and papermaking, plastics, electricity (such as high-speed turbine drives, generators, pumps), refrigeration, and ships. KUDOSWORLD supplies a large number of Disc coupling for various pumps.

In the field of precision transmission and automation, Disc coupling are used for servo motors, stepper motors, and general-purpose motors, commonly used for connecting motors with gearboxes, ball screws, encoders, measuring and testing machines, etc.

In the field of industrial automation, Disc coupling are mainly used in robots, automated production lines, etc.

In the aerospace field, Disc couplings are mainly used for power transmission between the engine accessory casing of fixed wing aircraft and the aircraft accessory casing, as well as between the engine and gearbox, and between the gearbox and the tail transmission system of rotary wing aircraft.

In the field of new energy, Disc coupling are applied in the drive system of electric vehicles, used to connect motors and transmission shafts, as well as the transmission system of wind turbines.

In addition, membrane couplings are also used in agricultural machinery, engineering machinery, electronic equipment, machine tool equipment, medical equipment, ships and other fields.
