6929574, Aug 16, 2005

Filed:

May 3, 2004

Appl. No.:

10/838027

Inventors:

Nicholas J. Laufenberg - Darien IL, US
Peter J. Ungs - Bolingbrook IL, US

Assignee:

CNH America LLC - Racine WI

International Classification:

F16H061/00
F16H059/00

US Classification:

474 70, 474 73, 56 103

Abstract:

A two speed shift mechanism for a belt drive that includes a rotatable shaft with a first pulley, and a tube concentric with the shaft and rotatable therearound. The tube includes a shift hub supporting a second pushy in axially spaced relation to the first pulley for concentric rotation about the shift hub. The mechanism further includes a collar mounted around the shift hub for rotation therewith and for axial movement between a position adjacent the first pulley and a position adjacent the second pulley. In a first position, the collar and the first pulley include elements engageable for connecting the collar to the first pulley for rotation of the collar, the shift hub, and the tube. In a second position, the collar and the second pulley include elements engageable for connecting the collar to the second pulley for rotation of the collar, the shift hub, and the tube.

Abstract:

A grain delivery conveyor for a grain tank of an agricultural combine includes a first gear box including a first input connectable in rotatably driven relation to a rotatable power source for rotation about a first axis, and a first output rotatable about a second axis angularly related to the first axis by rotation of the first rotatable input; a second gear box including a second rotatable input connected in rotatably driven relation to the first output for rotation about the second axis, and a second output rotatably driveable about a third axis angularly related to the second axis by rotation of the second rotatable input; and an elongate conveyor assembly connected in rotatably driven relation to the second output, the second gear box and the conveyor being jointly pivotable about at least the second axis for varying a position of a free end of the conveyor relative to the grain tank.

International Classification:

F16H007/02

US Classification:

474/073000, 192/069910

Abstract:

A two speed shift mechanism for a belt drive, including a rotatable shaft including a first pulley mounted thereon for rotation therewith, a tube concentric with the shaft and rotatable therearound, the tube including a shift hub mounted around a portion thereof for rotation therewith, and the shift hub supporting a second pulley in axially spaced relation to the first pulley for concentric rotation about the shift hub. The mechanism includes a collar mounted around the shift hub in the space between the pulleys for rotation with the shift hub and for axial movement relative thereto between a position adjacent the first pulley and a position adjacent the second pulley. The collar and the first pulley include elements cooperatively engageable when the collar is in the first position for connecting the collar to the first pulley for rotation of the collar, the shift hub and the tube therewith, and the collar and the second pulley include elements cooperatively engageable when the collar is in the second position for connecting the collar to the second pulley for rotation of the collar, the shift hub, and the tube therewith, the mechanism further optionally including a releasable element for holding the collar in the first and second positions, respectively.

Assignee:

CNH AMERICA LLC - New Holland PA

International Classification:

F16H 37/06

US Classification:

74665 G

Abstract:

A gear box assembly for a twin rotor combine is provided. The gear box assembly includes a two speed gear box having a casing, an input shaft, an output shaft, and a two speed gear assembly housed within the casing and operatively connected between the input shaft and the output shaft. The gear box assembly also includes a splitter gear box operatively connected to the output shaft. The splitter gear box includes a housing, and a splitter gear assembly housed within the housing and configured to split a torque provided by the output shaft between a first output shaft and a second output shaft extending from the housing in a direction opposite a direction the output shaft extends from the two speed gear box. The two speed gear box is pivotable relative to the splitter gear box housing.

International Classification:

A01D 34/04

US Classification:

56 101, 56257

Abstract:

A slot driven low profile sickle drive has an input rotatable about an upstanding rotational axis and carries an eccentric captured in a slot in one end of a pivot arm pivotable about an upstanding pivotal axis. A power source is connected in rotatably driving relation to the input. The opposite end of the pivot arm connects to a knife assembly of a sickle. The input, eccentric and pivot arm are generally flat, and the power source is vertically coextensive therewith for incorporation in or below the floor of a header of a plant cutting machine. Rotation of the input causes epicyclical orbiting of the eccentric, resulting in sideward pivoting of the opposite end of the pivot arm and sickle knife. A second drive can oppositely drive a second sickle knife, such that opposite forces generated by operation of the drives will be largely canceled.
