SWASH PLATE TYPE HYDRAULIC MOTOR AND SWASH PLATE TYPE HYDRAULIC PUMP

摘要

PROBLEM TO BE SOLVED: To provide a swash plate type hydraulic motor or a swash plate type hydraulic pump having a construction with which abrasion/cracking of the swash plate can be prevented, without applying a hardening process such as heat treatment to the swash plate.;SOLUTION: One embodiment of the present invention is a swash plate type hydraulic motor 1. A spherical surface part 8b is integrally formed on the swash-plate-side end face of a tilting piston 8. A plate member 10, which has a concave part 10a on the tilting-piston side having the same shape as the spherical surface part 8b and into which the spherical surface part 8b fits in a slidable manner, and a sliding surface 10b on the swash-plate side which slides on a second support surface 7b2, is arranged between the swash plate 7 and the tilting piston 8.;COPYRIGHT: (C)2013,JPO&INPIT
