US Patent 11168781 Lubricant feed in a vertically mounted gearbox

An arrangement includes a structure fixed to a housing, a bearing, and a planet carrier rotatably supported in the structure fixed to the housing via the bearing and an oil feedthrough ring. The oil feedthrough ring forms a lubricant-conducting connection between the structure fixed to the housing and the planet carrier. The structure fixed to the housing, the oil feedthrough ring, the bearing and the planet carrier together form a first cavity. The planet carrier forms at least one lubricant line which opens into the first cavity.
