Drive mechanism for a fluke drive and method for installning the same

A drive mechanism for a fluke drive, the drive mechanism being arranged to convert a rotary movement into a pivoting movement, the drive mechanism, comprising:

• a first part;
• a second part comprising a second-part engagement means;
• a third part comprising a third-part engagement means;
• and
• a rod part comprising a first end and a second end,
• wherein the second part is rotatable in relation to the first part along a rotary axis that is common to the first part and the second part,
• wherein the third part is reciprocatingly pivotable in relation to the first part about a first pivot axis that is not parallel to the rotary axis,
• wherein the first pivot axis is fixed in relation to the first part,
• wherein the second-part engagement means is arranged eccentrically with respect to the rotary axis,
• wherein the first end engages with the second-part engagement means,
• wherein the second end engages with the third-part engagement means, and
• wherein the third-part engagement means is pivotally connected to the second end so that the second end can pivot in relation to the third part about a second pivot axis, the second pivot axis being perpendicular to the first pivot axis.
