SWASH PLATE TYPE PISTON PUMP MOTOR |
摘要 |
<p>[Object] Increase abrasion resistance and seizing resistance of a slide surface of each of a swash plate and a swash plate support while improving productivity. [Means to Achieve Object] A swash plate type piston pump motor 1 is configured such that: a plurality of pistons 10 are arranged in a circumferential direction in a cylinder block 9 configured to rotate with a rotating shaft 5; the pistons 10 reciprocate such that tip end portions 10a thereof are guided by a smooth surface 26a of a swash plate 12; and the swash plate 12 is slidably supported by a concave surface 22 of a swash plate support 4 of a convex surface 32 to be able to tilt with respect to a rotating axis L, and concave surfaces 21 and 22 of the swash plate support 4 include quenched portions 21a and 22a, respectively, which are partially quenched by laser light.</p> |
