  • Patent number: 7261636
    Abstract: A drive in an agricultural machinery driveline has a drive housing (1), which forms an interior (18), and is at least partially filled with lubricant. A first shaft (4) is rotatably supported in the drive housing (1) around a longitudinal axis (13) and is guided out of the interior (18). First longitudinal teeth (8) connect, in a rotationally fast way, to a second shaft (9) via a second longitudinal teeth (10) formed to complement the first longitudinal teeth (8). One of the two shafts (4) has a receiving bore (5) arranged coaxially relative to the longitudinal axis (13). The bore (5) has longitudinal teeth (8) which enable insertion of the other shaft (9) by its longitudinal teeth (10). A lubricant guiding mechanism (19, 22, 29) is in the first shaft (4) or in the drive housing (1). In the connected condition of the two shafts (4, 9), the guiding mechanism connects the interior (18) to the receiving bore (5), as well as a valve (25).
