Lovejoy 69790406151 grid coupling hub with a keyway is designed to attach to a shaft on one side and to a grid coupling on the other side, allowing seamless torque transmission between two shafts.
A. A grid coupling is designed to connect two rotating shafts and transmit torque between them while accommodating any misalignment that occurs during application.
A. A curved hub tooth profile in a Lovejoy hub creates progressive contact with the flexible grid spring as the application torque increases, providing efficient transmission of power in properly aligned couplings.
A. A keyway is a groove or slot cut into a shaft or other parts of a machine to accept a key. The keyway also prevents using the wrong key in the wrong slot.
