摘要： A door operator for a reversibly operable door, such as a garage door, includes a frame and a carriage movably mounted on the frame and attached to a door for moving the door between open and closed positions. A flexible drive member, such as an endless chain, extends on the frame and is capable of moving the carriage. A drive train is on the frame connected for moving the flexible drive member. A motor housing is mounted on the frame within the motor housing and connected to the drive train. The motor has a shaft extending from the motor housing and engaging the drive train. A bearing assembly that includes metal thrust bearings is on the shaft adjacent to the motor. The metal thrust bearing assembly increases the performance of the electric motor, and thus provides a more powerful motor without changing to a larger motor or otherwise modifying the motor design. The motor is mounted on the frame so as to allow the shaft freely to move axially relative to the motor to permit the shaft to self-align. The rotor thus seeks its position of least resistance and maintains this position without manual adjustment, providing an improvement in motor performance.

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.

摘要： A door operator for a reversibly operable door includes a frame and a carriage movably mounted on the frame and attached to a door for moving the door between open and closed positions. A drive member, specifically a roller chain, extends along the frame and moves the carriage. A drive train is provided within a housing and is connected for moving the drive member, and a control circuit is provided for controlling the drive train to open and close the door. A pair of limit switches is mounted within the housing and connected to the control circuit for stopping the drive train when the door has reached a completed position. A pair of limit cams are adjustably mounted on a limit wheel within the housing and separate from the carriage for engaging the limit switches. The limit wheel, which is separate from the drive member, is connected to the drive train to rotate when the drive train moves the carriage. The placement of limit switches and associated connecting wiring along the frame in the garage ceiling is eliminated. The limit cams can be easily and automatically positioned on the limit wheel by pushing a single switch without any manual movement of the limit switches or of the movable cams that contact the limit switches.
