Abstract
The invention relates to a hydrodynamic bearing assembly in which a relatively broad bearing is divided into two bearings (2, 3) placed axially side by side. Both bearings are connected together to an inner bearing member (1) which is mounted to swivel universally over a spherical sector surface (16) in a cylindrical bore (18) of a surrounding housing. Between the bearing surfaces of both bearings (2, 3) there is provided in the bearing bore (6) a flowing fluid medium passage shared by the bearings, such as an annular groove (10). Through this passage the outlet flow area for the flowing fluid medium is doubled and length of the flow path in the bearing bore (6) reduced by one-half. Concurrently, a more perfect load pressure equalization is achieved on both bearings (2, 3) owing to the ball-joint-type universal bearing arrangement between the inner bearing member (1) and the housing (20).
