Abstract
A hydraulic rotary machine includes a plurality of pistons, a cylinder block accommodating the pistons, a shaft penetrating through the cylinder block, a swash plate making the pistons reciprocate to expand and contract a capacity chamber of the cylinder, a casing accommodating the cylinder block, a front cover closing an opened end of the casing, an extending portion formed in the front cover and extending along the shaft towards the cylinder block, and a first slide bearing provided between the extending portion and the cylinder block. The first slide bearing is fixed to the extending portion or the cylinder block by a pin member.
Claims8
A hydraulic rotary machine comprising:
- a plurality of pistons;
- a rotatable cylinder block including a plurality of cylinders for accommodating the pistons;
- a shaft penetrating through the cylinder block and coupling to the cylinder block;
- a swash plate configured to cause reciprocation of the piston in accordance with the rotation of the cylinder block so as to expand and contract a capacity chamber of the cylinder;
- a case member supporting one end of the shaft and accommodating the cylinder block;
- a cover member through which the other end of the shaft is inserted, the cover member closing an opened end of the case member;
- an extending portion formed in the cover member, the extending portion extending along the shaft towards the cylinder block;
- and
- a first slide bearing provided between the extending portion and the cylinder block, wherein
- the first slide bearing is fixed to the extending portion or the cylinder block by a fixing means.
