摘要: A garage door operator is disclosed to have a front coupling for a threaded screw of the operator and the rotor of the motor. The coupling includes a first coupling device that is a unitary coupling member with opposing recesses for receiving each of the rotor shaft and an end portion of the screw. The unitary coupling member thereby connects the screw to the motor for torque transmission from the motor. The second coupling device includes a thrust containment device that is supported on the screw, and an intermediate assembly disposed between the thrust containment device and an end portion of the guide rail of the door operator. A retainer component of the intermediate assembly restricts expansion of the thrust containment device.
