DOUBLE SIDED DOUBLE TELESCOPING DRIVE COUPLING

摘要

Embodiments of the invention provide a double-sided drive shaft with a telescoping end on each side, such that each telescoping end is able to extend and retract. The drive shaft is configured to transfer rotation from a rotational power source within an agricultural implement. The double-sided and double-telescoping drive shaft includes one or more shafts and one or more sleeves having an interior surface configured to transfer torque. In particular, the double-telescoping properties of the drive shaft may provide greater extension and retraction, flexibility, and freedom of movement than a standard drive shaft.

主权项

1. A drive coupling, comprising a center sleeve comprising an interior surface configured to transfer torque, and open left and right open ends opposite one another and communicating with the center sleeve interior surface;
a first intermediate sleeve slidingly received in the left open end and having a first exterior surface at least partially conforming to the center sleeve interior surface, the first intermediate sleeve comprising a first interior surface configured to transfer torque, and a first open end opposite the center sleeve and communicating with the first interior surface; a second intermediate sleeve slidingly received in the right open end and having a second exterior surface at least partially conforming to the center sleeve interior surface, the second intermediate sleeve comprising a second interior surface configured to transfer torque, and a second open end opposite the center sleeve and communicating with the second interior surface; a driving member having a driving shaft conforming to the first interior surface of the first intermediate sleeve and slidingly received in the first intermediate sleeve; and a driven member having a driven shaft conforming to the second interior surface of the second intermediate sleeve and slidingly received in the second intermediate sleeve.
