CNC machine tool couplings are typically classified according to their structural form, size specifications, and application scenarios. Common structural forms include diaphragm couplings, swivel-shaped flexible couplings, and bellows couplings. Each structural form has its unique advantages and applicable range.
Diaphragm Couplings: These couplings transmit torque through a metal diaphragm, possessing high torsional stiffness and compensation capability, suitable for high-speed, high-precision CNC machine tools. Their models are usually named according to the number, size, and connection method of the diaphragms.
Swivel-Shaped Flexible Couplings: Swivel-shaped flexible couplings utilize the deformation of elastic elements to compensate for the relative displacement between two shafts, featuring simple structure and convenient installation. Their models are usually distinguished by the shape, size, and material of the elastic element.
Bellows Couplings: Bellows couplings transmit torque and compensate for displacement through the elastic deformation of the bellows, suitable for applications requiring large compensation amounts. The model number is named according to the material, number of corrugations, and connection size of the corrugated pipe.
