A crank-operated packer mechanism includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings. The connection further includes a locking feature for locking the connection, such as a locking nut screwed onto a threaded outer end of the crank pins when inserted into the opening. Fixing of rotary bearings onto the crank pins is done by a fixing nut which at the same time serves as a disassembling aid for the spline connection. The crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced about its central rotation axis. Also a baler including the aforementioned packer mechanism.

Crank-operated packer mechanism for an agricultural baler

A crank-operated packer mechanism includes a crank shaft including crank pins and crank arms. At least some of the crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced. The arms may, for example, be curved or hook-shaped. The crank shaft further includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings.

An industrial work vehicle including a frame and a first shaft rotatably connected to the frame via first and second bearings. The work vehicle further includes a second shaft rotatably positioned in line with the first shaft and connected to the first shaft via a coupling. The second shaft is further connected to the frame via a third bearing. The coupling includes a first connection and a second connection. The first connection connects the first shaft to the second shaft via a fourth bearing adapted to support a radial load and to accommodate an axial rotation and an angular misalignment of one shaft with respect to the other shaft. The second connection connects the first shaft to the second shaft via flange elements which are interconnected via an intermediary element adapted to transmit a torque and to accommodate a misalignment of one shaft with respect to the other shaft.
