摘要： A swash plate type hydraulic rotating machine includes: a rotating shaft; a valve plate; a swash plate; a cylinder block on the outside of the rotating shaft slidingly contacting the valve plate; cylinders provided in the cylinder block having axially movable pistons therein; shoes on a distal end of respective pistons; an annular keep plate between the swash plate and the cylinder block supporting the shoes having a plain bearing within the inner periphery of the keep plate, the plain bearing supporting the keep plate to push the keep plate toward the swash plate side; and set springs biasing the plain bearing and the cylinder block toward the opposite sides in the axial direction. The swash plate type hydraulic rotating machine is configured such that, when in an assembled state, a gap in the axial direction between the cylinder block and the plain bearing is 0 or a fine gap.

摘要： A squeeze film damper for a bearing and a vibration damping mechanism capable of damping the vibration of a rolling bearing are provided. The squeeze film damper is small in construction and can be easily made by mass production. The vibration damping mechanism is capable of damping both radial and axial vibrations. A bearing housing 15 is provided with a bearing holding bore 16 of a diameter greater than the outside diameter of the outer ring 14 of a bearing, and an oil hole 19 through which oil is supplied into the bearing holding bore 16. A vibration damping mechanism 1 is formed by inserting a thin, flat sheet 17 provided with slits into an annular space formed between the inner wall of the bearing holding bore 16 and the outside surface of a bearing held in the bearing holding bore 16 so as to surround the bearing. Parts of the thin, flat sheet extending between the adjacent slits serve as elastic beams. The elastic beams center the bearing and support the centered bearing elastically. The vibration of the bearing is damped by the squeeze film effect of an oil film formed by supplying oil into the annular space.
