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

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

A drive unit for oscillatingly driven mowing sickles has a first transmission unit {} with a first housing () defining a first axis (). A rotor () is rotationally supported in the first housing () around the first axis (). A first internal gear wheel () is fixed in the first housing () and provided with internal teeth. A toothed pinion () is rotationally supported in the rotor () around a second axis (). The second axis () is radially off-set to the first axis (). The toothed pinion () forms the output element of the drive unit and meshes with the first internal gear wheel (). A second transmission unit () has an output () non-rotationally connected to the rotor () of the first transmission unit (). The second transmission unit () is formed as a step-down gear. A motor (), with an output shaft (), rotationally drives the second transmission unit (). The rotational speed Nis reduced by the second transmission unit (), formed as a step-down gear, to the rotational driving speed Nof the first transmission unit ().
