Flange coupling

Flange couplings are mechanical devices used to connect two shafts together in order to transmit power or torque from one shaft to another. They have two flanges mounted on each shaft end to make a connection using nuts, bolts, and gaskets. Flange Couplings are specifically designed for applications where alignment accuracy, high torque transmission, and vibration resistance are crucial. Components of a Flange Coupling A typical flange coupling consists of two flanges, each attached to the end of a shaft. These flanges are then bolted together, with a gasket or a sealing mechanism in between. Refer to Fig. 1 below. The design of flange couplings can vary, but they generally consist of the following components: Flanges: These are the circular plates with holes for bolts. Flanges are typically made of materials like steel, cast iron, or aluminum for strength and durability. Bolts: Bolts pass through the holes in the flanges and are tightened to securely hold the two flanges together. Gasket or Seal: A gasket or seal is often used between the flanges to prevent leakage of fluids or lubricants and to maintain the alignment of the shafts Working of a Flange Coupling With the flanges securely bolted together, the two shafts become mechanically linked. When one shaft rotates, it transmits torque to the other shaft through the flange coupling. The gasket or seal between the flanges prevents any leakage of fluids or contaminants. Types of Flange Couplings There are three types of flange couplings that are widely used in industries. They are: Protected Flange Coupling Unprotected Flange Coupling, and Marine Flange Coupling
