Connection arrangement between a drive of a mowing sickle and a mowing sickle

Abstract

A connection arrangement between a mowing sickle drive and a linear reciprocating mowing sickle has a first metallic connection element (4). The first connection element (4) forms either one component with the mowing sickle (1) or serves to connect the same. The first connection element (4) is at least partially formed annularly and includes a circular cylindrical bore (6), which defines a longitudinal axis (5). The first connection element (4) is slotted and includes a clamping mechanism (11) to change the cross-section of the bore (6). A metallic ring (14) has a circular cylindrical outer face (19) to nest in bore (6). A hollow spherical inner face (18) is on the intermediate ring (14). The intermediate ring (14) has at least one slot on its circumference. A rotational rolling member bearing has an outer metallic bearing ring (20) and is closed in a circumferential direction. The outer bearing ring (20) has a spherical outer bearing face (21), which is formed into the inner face (18) of the intermediate ring (14) and enclosed by the intermediate ring (14). The outer bearing ring has at least one outer race (22). At least one metallic inner bearing ring (23), closed in a circumferential direction is positioned inside of said outer bearing ring (20). The inner ring (23) includes at least one inner race (24) and has a through extending receiving bore (26). Rolling members (25) are arranged between the outer race (22) and the inner race (24). A second connection element (27), which includes a driving trunnion (29), rests in the receiving bore (26).

Claims

1. A connection arrangement between mowing sickle drive and a linear reciprocating mowing sickle comprising: a first metal connection element forming either one component with the mowing sickle or serving for connection with the mowing sickle, said first connection element being at least partially annularly formed and including a circular cylindrical bore defining a longitudinal axis, said first connection element including a slot and a clamping mechanism for changing the cross-section of the bore;a metal intermediate ring including a circular cylindrical outer face adapted to nest with said bore, a hollow spherical inner face on said intermediate ring, and at least one slot on a circumference of said intermediate ring;a rotational rolling member bearing including a metal outer bearing closed in a circumferential direction, said outer bearing ring including a spherical outer bearing face, formed fitting into the inner face of the intermediate ring and being enclosed by the intermediate ring, at least one outer race formed on said outer bearing ring, at least one metal inner bearing ring closed in circumferential direction, said inner ring including at least one inner race and a through extending receiving bore, rolling members are arranged between the outer race and the inner race; anda second connection element includes a driving trunnion, which nests in the receiving bore.

2. The connection arrangement according to claim 1, wherein the rotational rolling member bearing is formed as a double taper roller bearing.

3. The connection according to claim 1, wherein the first connection element has a first front face and a second front face along the longitudinal axis and said first connection element is interrupted by a first slot, which extends between the first front face and the second front face.

4. The connection arrangement according to claim 3, wherein lugs are formed at both sides of the first slot on the first connection element, said lugs have through holes with at least one clamping screw.

5. The connection arrangement according to claim 1, wherein the intermediate ring has a first end face and a second end face along the longitudinal axis and said intermediate ring is interrupted by a second slot extending between the first end face and the second end face.

6. The connection arrangement according to claim 1, wherein the intermediate ring has a first end face and a second end face along the longitudinal axis and second slots are provided on a circumference, said second slots extending from one or both end faces with their ends, respectively, in front of the other end face.

7. The connection arrangement according to claim 6, wherein the second slots, starting from different end faces, are alternately arranged over the circumference of the intermediate ring.

8. The connection arrangement according to claim 5, wherein the second slot, projected onto the longitudinal axis, extends parallel or intersects the longitudinal axis.

9. The connection arrangement according to claim 6, wherein the second slots extend parallel to the longitudinal axis.
