BEARING ASSEMBLY FOR A
RETRACTABLE AUGER FINGER
BackArvund of the Invention 1. Field of the Invention This invention relates to a bearing assembly for a retractable finger in a conveying auger and in particular to a bearing assembly with two identical bearing halves coupled together by integral coupling structures in place of a pivot pin.
RETRACTABLE AUGER FINGER
BackArvund of the Invention 1. Field of the Invention This invention relates to a bearing assembly for a retractable finger in a conveying auger and in particular to a bearing assembly with two identical bearing halves coupled together by integral coupling structures in place of a pivot pin.
2. Description of Related Art It is common in platforms for harvesters to assist the transfer of crop material into a feeder conveyor with a crop converging auger that contains spiral flighting to move crop material from the ~nds of the platform to the platform center to the feeder i5 conveyor. The center portion of the auger immediately forward of the feeder conveyor is provided with a rotating and retracting finger arrangement in which a finger crank shaft is fixed inside of and eccentric to the rotating auger tube.
Elongated fingers journaled on the finger crank shaft extend generally radially through guide slots in the surface of the tube so that as the tube rotates, the fingers are rotated about their shaft and reciprocated in the guide slots due to the eccentricity of the finger crank shaft with respect to the auger tube. The arrangement is timed so that the fingers extend to engage crop material and sweep it under the tube, into the feeder conveyor and retract to assist in releasing the material into the feeder conveyor.
The bearing assembly for. each finger includes first and second bearing halves. The bearing halves are coupled together by a pivot pin or hinge pin to allow the bearing halves to rotate between open and closed positions. in the open position, the bearing halves can be placed around the finger shaft. The bearing assembly is then closed on the shaft and upon a finger and fastened to the finger to prevent the bearing assembly form being opened.
It is possible for the hinge pin to work out of the bearing halves, allowing the assembly to corns apart inside the auger tube. It is then necessary to stop operation of the harvesting machine to re-assembly the bearing before extensive damage 1s done to the auger.
Summary of the Invention Accordingly, it is an object of the invention to provide a bearing assembly that can be assembled without the need for a hinge pin.
The bearing assembly of the present invention consists of two bearing halves that are identical to one another. The bearing halves can be joined together with the bearing halves in an open position relative to one another_ From this open position, the bearing halves can be rotated about a hinge axis to a closed position in which t0 the bearing halves form a cylindrical bore for the finger shaft. In the closed position, the bearing halves are locked together and cannot be separated from one another at the hinge. Once assembled and an auger finger is installed, the bearing halves are bolted together to prevent rotation of the bearing halves back to the open position where the two halves can be separated at the hinge portion.
t5 The bearing halves each have an inner semi-cylindrical bearing surface such that when the two halves are mated in a closed position, they define a cylindrical bore journaled on the crankshaft. A hinge portion extends from the bearing portion and consists of a pair of pivot sections spaced from one another along a hinge axis that is parallel to the axis of the cylindrical bore formed by the two bearing surfaces.
20 The pivot sections are axially spaced a distance approximately equal to the axis!
thickness of each of the pivot sections. One pivot section has a tab extending axially therefrom. The other pivot section has a center recess extending axially into the pivot section on one face and a radial slot extending radiaily outward from the recess. The slot is aligned with the tab of the other pivot section such that when two bearing 25 halves are mated together, the tab of one bearing half passes through the slot on the other bearing half and into the recess. Once the tab is inserted into the recess, the two bearing halves can be rotated relative to one another with each tab rotating within the recess in the other bearing half. Once the two bearing halves are mated i;n a closed position, the tabs are no longer aligned with the slots such that the tabs are 30 held within the axial bore.
The two bearing halves can pivot relativ~ to one another by the hinge axis but can only be separated when they are in an open position. This eliminates the need for a hinge pin.

Description of the Preferred Embodiment The invention is embodied in the platfom~ auger of the otherwise conventional grain-cutting platform 12 of a combine shown in side elevation in Fig. 1.
Platform 12 is mounted to a combine feederhouse 14. The platform 12 consists of a basic open front structure defined by a floor 18, a rear wall 20 and opposite side sheets 22. A
cutterbar 24 extends forward from the floor to sever the standing crop. A reel rotates above the cutterbar 24 to control the movement of crap material onto the cutterbar 24 and over the forward portion of the floor 18, into engagement with a platform auger 28.
The cutting platform 12 is much wider than the feederhouse 14 and the platform auger 28 converges, or laterally transfers, aop material from the cutterbar to the center of the platform. There the crop material is delivered to the feederhouse ~
where it is engaged by the feederhouse conveyor 3d and moved rearwardly and upwardly over the feederhouse floor 32 for delivery to the combine threshing cylinder (not shown).
The auger 28 is conventional in many respects and its general form in mounting is described only briefly herein. Such augers and their operation are well known. As indicated in Fig. 2, the platform auger 28 is supported by and joumaled on a shaft assembly 34, including opposite coaxial auger shaft portions 36 and an offset or eccentric finger crank shaft portion 38 rigidly connected to the auger shaft portions 36 by a pair of cranks 40. The auger shaft portions 36 at the opposite ends of the auger 28 are mounted and secured against rotation in the side sheets 22 of the platform 12, as is conventional but not shown in the dra~ivings.
The auger structure includes an elongated cylindrical tube 42, concentrically mounted and journaled on the auger shaft portions 36 by means of bearings 44 carrying spiders or bulk heads 46 rigidly attached to the inside of the auger tube 42.
Helical auger flighting sections 48 and 50 of opposite hand, r~spectively, cooperate with the platform floor 18 and rear wall 20 as the auger rotates to convey crop material to a central portion of the auger 28. A plurality of finger bearing assemblies 52 are joined an the finger crankshaft 38. Each bearing assembly 52 carries a finger 54_ Each finger 54 extends through a guide assembly 56 mounted in the wall of the 2o auger 42. Removable covers 58 provide access to the inside of the auger 252, for example, servicing the bearing assemblies 52. Suitable, conventional drive means, not shown, are provided for rotating the auger 28 on the shaft portions 36.
Each bearing assembly 52 is comprised of two identical bearing halves 60.
Each bearing half 60 consists of a bearing portion 62 having an internal, semi cylindrical bearing surface 64. At one side of the bearing portion and extending radially of the semi-cylindrical bearing surface 64 is a finger retaining portion B6. The finger retaining portion 66 has a recfiangular shaped recess 88 and a semi-cylindrical recess 70 adjacent thereto leading to a distal end surface 72. A bore 74 extends through the finger retaining portion 66 in the recess 88.
With reference to Figure 6, the fnger 54 has a square head 78 at one end with a through-bore 78. The finger head is placed in the recess 68 when the bearing halves 60 are closed upon the finger- A nut and bolt assembly 80 extends through the bores 74 in the bearing halves and the bore 78 in the finger to both retain the bearing halves in the closed position and to fasten the finger to the bearing assembly as shown in Figure 5. Other fasteners can be used to held the bearing halves together such as a sleeve or cap surrounding the finger retaining portion with a spring clip, etc. to hold the sleeve in place. The closed bearing assembly is shown in Figure 5 surrounding the finger crank shaft 38.
Each bearing half has a hinge portion 82 extending from the bearing portion 62 in the opposite direction from the anger retaining portion 66. The hinge portion 82 of each bearing half includes a pair of pivot sections 84 and 86. As described below, the pivot sections define a hinge axis 88 far each bearing assembly. The hinge axis 88 is parallel with the axis 65 defined by the semi-cylindrical bearing surface 64. The two pivot sections are axially spaced along the axis 88 by a distance approximately equal to the axial thickness of each pivot section. The pivot section 86 has one axial face 90 that is formed with a circular recess 92 concentric with the axis 88_ A radial slot 94 extends outward from the recess 92_ The other pivot section 84 has a face 96 from which axially extends an elongated tab 98. The tab 98 has a length "L"
shown in Fig. 3 that is slightly less than the diameter of the recess 92 in the pivot section 86.
The tab 98 is aligned lengthwise with the slot 94 and the thickness of the tab 98 is 2Q slightly less than the width of the slot 94.
Two bearing halves 80 are joined together by first orienting the bearing halves as shown in Figure 3. There, the tab 98 of one bearing half is aligned with the slot 94 of tt~e other bearing half. The bearing halves are moved together by inserting the tabs 98 through the respective slots 94 and Infio the recesses 92 of the other bearing 2s half to the position shown in Figure 4. This is the open position of the bearing assembly- The two bearing halves rotate relatNe tv one another about the hinge axis 88, in a clam shell fashion, to the closed position shown in Figure 5. The bearing halves rotate approximately 10tJ° relative to each other such that the tabs 98 are no longer aligned with the respective slots 94 in the other bearing half as shown in 30 Figure 5.
The structure of the hinge portions 82 with the tabs 98 and the respective slots 94 and recesses 92 enable the bearing halves to be joined together and to rotate about a hinge axis without the need for a separate hinge pin. Unless the two bearing halves are rotated to the open posltlon of Figure 4, the bearing halves cannot be separated from one another. The pivot sections $4 and 86, together with their tabs 9$, recesses 92 and slots 94 farm integral pivot means for coupling the bearing halves together for rotation about a hinge axis between open and closed positions, wherein in the open position, the bearing halves can be separated from one another and in the closed position. The pivot means couple the bearing halves together.
The invention should not be limited to the above-described embodiment, but should be limited solely by the claims that follow.
