Abstract
A rotary screen door assembly for a work vehicle includes a door configured to couple to an enclosure of the work vehicle for movement between a closed position and an open position, and a screen rotatably supported on the door and configured to filter air passing through an air inlet defined in the door. The rotary screen door assembly also includes a first shaft segment rotatably supported on the door and coupled to the screen, the first shaft segment having a first magnetic coupler configured to engage a corresponding second magnetic coupler of the work vehicle.
Claims10
A rotary screen drive assembly for a work vehicle, the work vehicle including a door movable between a closed position and an open position, and a screen rotatably supported on the door and configured to filter air passing through an air inlet defined in the door, the rotary screen drive assembly comprising:
- a first shaft segment having a first end configured to be coupled to the screen to drive the screen to rotate relative to the door, and having a second end affixed to a first magnetic coupler;
- and
- a second shaft segment having a first end configured to be coupled to the prime mover, and having a second end affixed to a second magnetic coupler configured to selectively engage the first magnetic coupler to rotatably couple the first shaft segment to the second shaft segment when the door is in the closed position;
- wherein each magnetic coupler defines an end face, and each magnetic coupler is configured such that, in the closed position of the door, the end faces of each magnetic coupler are oriented opposed and parallel to one another and are spaced apart from one another such that an uninterrupted gap is defined between the end faces.
