Coupling

An industrial work vehicle in the form of an agricultural work vehicle, comprising:

• a frame;
• a first bearing;
• a second bearing;
• a third bearing;
• a coupling comprising a first connection, a second connection, and a spline connector;
• a first shaft rotatably connected to the frame via the first and second bearings, and the spline connector of the coupling is connected to the first shaft via a spline connection;
• a second shaft rotatably positioned in line with the first shaft and connected to the first shaft via the coupling, the second shaft being further connected to the third bearing;
• a fourth bearing adapted to support a radial load and to accommodate an axial rotation and an angular misalignment of the first shaft with respect to the second shaft, and the fourth bearing is a spherical bearing;
• and
• one or more flange elements interconnected via an intermediary element adapted to transmit a torque and to accommodate a misalignment of the first shaft with respect to the second shaft,
• wherein the first connection of the coupling connects the first shaft to the second shaft via the fourth bearing, and
• wherein the second connection of the coupling connects the first shaft to the second shaft via the one or more flange elements, wherein movements resulting from the misalignment of the first shaft and the second shaft are accommodatable by both the fourth bearing and the intermediary element such that a wear on the spline connection is decreased.
