A washing machine coupler can perform different functions depending on whether it is found as part of the agitator or as part of a direct-drive motor. As part of the agitator, the coupler is located between the agitator and the transmission shaft, connecting the two.
A washing machine coupler can also be found as part of the direct-drive motor. This coupler is made up of two plastic drive forks and a central rubber coupling. The function of the direct-drive motor coupler is to connect the transmission to the motor, transferring power between the two. The rubber coupler absorbs the torque energy generated by the motor to prevent the plastic portions from breaking.
