In mechanical systems, a coupling is used to connect two shafts or rotating components in order to transmit torque, power, or motion. Couplings help in accommodating misalignments, absorbing shock loads, and protecting equipment from damage. Here are the main types of couplings commonly used in the petroleum and industrial sectors: --- 1. Rigid Coupling ⚙️ Principle: Provides a solid, fixed connection between two shafts, with no flexibility or movement. Application: Used in applications where sh
