A companion flange is a type of flange that is commonly used in mechanical systems, particularly in the transmission of power from a motor to a driven component such as a pump or generator. The companion flange consists of two flanges that are bolted together, with one flange attached to the output shaft of the motor and the other flange attached to the input shaft of the driven component.
Companion flanges are designed to transmit torque and axial forces between the motor and driven component, while also allowing for some misalignment between the two shafts. They are typically made from materials such as steel or aluminum and are available in a range of sizes and configurations to suit different applications.
One advantage of using companion flanges is that they can be easily replaced if they become worn or damaged, without the need to replace the entire shaft assembly. They are also relatively simple to install and can be used in a variety of different mechanical systems, making them a popular choice in many industries.
