Abstract:
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, said metal intermediate ring being axially adjustable along said longitudinal axis with respect to said first metal connection element and a hollow spherical inner face on said intermediate ring, and at least one slot on a circumference of said intermediate ring; a pretensioned rotational rolling member bearing including a metal outer bearing ring 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 the 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; and a second connection element includes a cantilevered driving trunnion, which nests in the receiving bore.
