Abstract

See full text

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.
