SWASH PLATE-TYPE HYDRAULIC ROTARY MACHINE AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2015/166629

A1

A swash plate-type hydraulic rotary machine is provided with a first movement restriction mechanism (80) for restricting the movement of a spherical bush (8) to one axial side relative to a rotating shaft (3). The first movement restriction mechanism (80) is, for example, a restriction member provided to the rotating shaft (3) so that the one axial side of the spherical bush (8) comes into contact with the restriction member. The swash plate-type hydraulic rotary machine is further provided with: a stopper (35) mounted to the rotating shaft (3) so that, outside a casing (2), the stopper (35) axially faces a bearing (26); and a gap adjustment member (36) provided between the bearing (26) and a gap adjustment member (36). The gap adjustment member (36) is inserted into a gap (G3) that is formed between the stopper (35) and the bearing (26) when the spherical bush (8), a pressing plate (7), a shoe (6), and a swash plate (5) are axially in close contact with each other, and thus, the gap adjustment member (36) restricts the movement of the rotating shaft (3) to the one axial side relative to the casing (2).
