A drive in an agricultural machinery driveline has a drive housing (), which forms an interior (), and is at least partially filled with lubricant. A first shaft () is rotatably supported in the drive housing () around a longitudinal axis () and is guided out of the interior (). First longitudinal teeth () connect, in a rotationally fast way, to a second shaft () via a second longitudinal teeth () formed to complement the first longitudinal teeth (). One of the two shafts () has a receiving bore () arranged coaxially relative to the longitudinal axis (). The bore () has longitudinal teeth () which enable insertion of the other shaft () by its longitudinal teeth (). A lubricant guiding mechanism () is in the first shaft () or in the drive housing (). In the connected condition of the two shafts (), the guiding mechanism connects the interior () to the receiving bore (), as well as a valve (). The valve () is integrated into the lubricant guiding mechanism () and can be set between a closed position, closing the lubricant guiding means (), and an open position. The valve () is transferable from the closed position into the open position by connecting the first shaft () to the second shaft ().

Drive

A gear drive has a drive housing () with a driveshaft () exiting the drive housing () through a bore (). The driveshaftis rotatably supported in the drive housing () around an axis of rotation X&#x2014;X. A connecting shaft () is arranged inside the drive housing (). The connecting shaft () is connected in a rotationally fast way to a drive gear (). A torque limiting coupling () is arranged inside the drive housing (). The input end of the torque limiting coupling () is connected to the driveshaft (). The output end of the torque limiting coupling () is connected to the connecting shaft (). The driveshaft () and the connecting shaft () are supported relative to one another by a radial bearing (). The gear drive ensures that the driveshaft () and the connecting shaft () can more easily accommodate bending moments and transverse forces.

Gear drive with integrated torque limiting coupling

An angle drive, especially for agricultural implements, has a housing with two housing portions (1, 2). The two housing portions (1, 2) abut one another at a right angle. The angle drive is provided with a first bevel gear (11) arranged in the first housing portion. A second bevel gear (27) is arranged in the second housing portion. The two bevel gears (11, 27) are each supported by rolling contact bearings (16, 17, 33). The housing interior is sealed by seals (20, 20') between the first bevel gear (11) and the first housing portion (1) and between the second bevel gear (27) and the second housing portion (2). The two housing portions (1, 2) which concentrate on merely covering the outlines of the two bevel gears (11, 27) and provide an aperture (25) in the region of abutment between the two housing portions (1, 2), in which the two sets of teeth (14, 18) engage one another, produce a compact unit with a small enclosed volume. Thus, a little space is required and the required amount of lubricating oil is also small.
