摘要： A bearing for a gearbox, the bearing having a cylindrical body. The cylindrical body defines a hollow interior chamber. The cylindrical body has a gear supporting section. The gear supporting section has a cross-section formed by three lobes equally distributed around a circumference of the cylindrical body. Each of the lobes has a land portion having a first radius over at least 20% of the lobe. Each lobe also has a tapered portion that gradually slopes from the first radius of the land portion to a reduced radius region that is smaller than the first radius. The tapered portion is formed over less than 80% of each lobe. Each lobe also has an opening formed in the reduced radius region and a flow passage fluidly connecting the hollow interior of the cylindrical body with the opening formed in the reduced radius region.

摘要： A hydrodynamic plain bearing has a bearing shell with an inner surface forming a bearing surface for a rotating shaft or the like. The bearing surface, in order to form a bearing having a multi-wedge bore, has a plurality of surface segments arranged one after the other in the circumferential direction and each forming a circle segment having a radius R by way of the inner circumference of the surface segments. The center point of the circle segment of each surface segment is shifted relative to a center point of the bearing shell by an eccentricity. The bearing shell has two halves, each extending over 180° of the bearing surface and joined in a joint plane. At least one surface segment is offset from the center point of the bearing shell along an offset plane at an angle to the joint plane in the circumferential direction of the bearing shell.
