  • Publication number: 20260185605
    Abstract: A lubricating device for a planetary transmission includes a planetary carrier including two carrier webs, a bearing pin arranged on the carrier webs, a bearing arranged on the bearing pin, a planetary gear mounted via the bearing, and two thrust plates arranged on either side of the planetary gear. One of the carrier webs includes a first channel-like depression arranged on a surface facing the planetary gear and arranged to feed a lubricant from radially outside of the thrust plate to the bearing. The other carrier web includes a second channel-like depression arranged on a surface facing the planetary gear and arranged to discharge the lubricant from the bearing radially outside. The first depression is arranged offset and radially further inward than the second depression such that the lubricant flows via the first channel-like depression, axially through the anti-friction bearing, and is drained via the second channel-like depression.

  • Patent number: 12516728
    Abstract: An oil collecting pan for a planetary gearbox includes a pan body and a retaining plate. The pan body includes a channel-like oil collection space and axially protruding, hollow oil feed ports which communicate with the channel-like oil collection space. The retaining plate extends radially into the channel-like oil collection space and runs at least partially circumferentially through the channel-like oil collection space. The retaining plate forms an oil retaining space within the channel-like oil collection space.

  • Patent number: 12326191
    Abstract: A planetary gearbox includes a shaft, a planetary carrier, first and second planetary pins arranged on the planetary carrier, first and second planetary gears mounted on the planetary pins via respective bearings, and a lubricant collecting tray. The shaft has a shaft channel for radially conducting a lubricant to an outer face of the shaft and the planetary pins have respective pin channels for conducting the lubricant to the respective bearings. The lubricant-collecting tray has a collection space for collecting the lubricant supplied via the shaft channel and hollow feed ports that open into respective pin channels. The hollow feed port closest to the shaft channel, when viewed in a circumferential direction, has an opening cross-section that is less than an opening cross-section of the other hollow feed port.

  • Patent number: 10568271
    Abstract: A detection arrangement for detecting a state of wear of a chopping assembly comprises at least one magnet arrangement which includes a magnetic excitation arrangement and a flux-conducting device magnetically coupled thereto. The magnet arrangement provides a pole arrangement which forms at least one magnetic pole for outwardly conducting magnetic flux. At least one portion of the chopping blades moves past the pole arrangement during a rotation of the cutting cylinder, and forms an air gap arrangement including at least one air gap with respect to the pole arrangement and, as a result, at least one magnetic circuit excited by the excitation arrangement is closed via the chopping blade. At least one portion of the magnetic flux generated by the magnetic excitation arrangement is longitudinally guided in the chopping blade at least across one longitudinal portion of the chopping blade.

  • Patent number: 9738310
    Abstract: A steering system for an agricultural vehicle has at least one steering cylinder for changing a steering angle of the agricultural vehicle, a hydraulic main steering valve for pressurizing the at least one steering cylinder, a steering transducer for actuating the main steering valve, a steering boost for controlling an adjustment characteristic between the steering transducer and the at least one steering cylinder and a sensor system for detecting an external signal of the agricultural vehicle. The steering boost controls the adjustment characteristic on the basis of the detected external signal.
