Abstract Radial slide bearing in the form of a three wedge bearing includes a bearing shell formed of an upper and a lower longitudinal half shell, a bearing bushing mounted in the shell and formed with shaft-bearing surfaces on the inner periphery thereof, the bearing shell and bearing bushing being comprised of three radial wedge segments with respective sickle-shaped spaces distributed over the inner periphery for building up therein wedges of lubrication for lubricating a rotary shaft receivable in the bearing bushing, the sickle-shaped spaces each having a leading edge in direction of rotation of the shaft, oil inlet channels formed in the bearing shell and the bearing bushing and communicating with the respective spaces at the leading edges thereof, and oil outlet channels also formed in the bearing shell and the bearing bushing and communicating with the respective spaces at a location thereof downstream from the leading edges thereof, one of the three wedge segments being located at the top of the bearing shell and extending over the bearing surface at the upper half shell substantially concentrically to the vertical axial plane of the bearing shell, the upper wedge segment including an adjusting segment wherein the respective sickleshaped space of the upper wedge segment is formed, the adjusting segment being adjustably mounted in the bearing shell for adjusting lubrication clearance between the bearing surface thereof and the shaft receivable in the bearing bushing so as to vary oil pressure forces exertable on the upper part of the shaft.
Radial slide bearing in the form of a three wedge bearing comprising a bearing shell formed of an upper and a lower longitudinal half shell, a bearing bushing mounted in said shell and formed with shaft-bearing surfaces on the inner periphery thereof, said bearing shell and bearing bushing being comprised of three radial wedge segments with respective sickle-shaped spaces distributed over said inner periphery for building up therein wedges of lubrication for lubricating a rotary shaft receivable in said bearing bushing, said sickle-shaped spaces each having a leading edge in direction of rotation of the shaft, oil inlet channels formed in said bearing shell and said bearing bushing and communicating with the respective spaces at said leading edges thereof, and oil outlet channels also formed in said bearing shell and said bearing bushing and communicating with the respective spaces at a location thereof downstream from said leading edges thereof, one of said three wedge segments being located at the top of said bearing shell and extending over the bearing surface at the upper half shell substantially concentrically to the vertical axial plane of said bearing shell, said upper wedge segment including an adjusting segment wherein the respective sickle-shaped space of said upper wedge segment is formed, said adjusting segment being adjustably mounted in said bearing shell for adjusting lubrication clearance between the bearing surface thereof and the shaft receivable in said bearing bushing so as to vary oil pressure forces exertable on the upper part of the shaft.
