A Half Gear Coupling is a type of flexible coupling used to connect two shafts with limited axial movement while transmitting torque and rotational motion between them. As the name suggests, a half gear coupling covers only half of the circumference of the connected shafts, providing a semi-enclosed coupling arrangement. This consists of two halves, each with a semi-circular gear profile. When the two halves are bolted together, they form a complete gear that covers half of the circumference of each shaft. Half Gear Coupling is commonly used in various industrial application s, such as pumps, compressors, generators, and other machinery that require torque transmission while allowing some misalignment compensation.
