What is dog clutch?

A dog clutch is a type of mechanical coupling used to connect two shafts, allowing for the transfer of torque between them. It consists of a series of interlocking teeth or "dogs" that engage to create a rigid connection when aligned, and disengage to allow for free rotation or separation. Dog clutches are commonly used in applications such as gearboxes and automotive transmissions, where quick engagement and disengagement of power are needed. They are valued for their simplicity and reliability in high-torque situations.
