Title:
RADIAL PISTON TYPE HYDRAULIC MACHINE AND WIND POWER GENERATION DEVICE
Document Type and Number:
Japanese Patent JP2014129783
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radial piston type hydraulic machine in which a cylinder block body has high endurance, and a wind power generation device.SOLUTION: A radial piston type hydraulic machine comprises: a plurality of pistons 22 arranged in radial directions; a plurality of cylinder sleeves 40 for guiding the plurality of pistons 22; a cylinder block body including a plurality of sleeve holes into which the plurality of the cylinder sleeves 40 are inserted respectively; and a cam 29A opposed to the plurality of pistons 22. Piston guide portions of the plurality of cylinder sleeves 40 are inclined with respect to the radial directions respectively so that the circumferential positions of the cylinder sleeves 40 on the end side closer to the cam 29A is shifted to the downstream side in the rotation direction of the cam 29A with respect to their circumferential positions on the other end side. The angles of cylinder center axes of a plurality of cylinders with respect to the radial directions are larger than the angles of sleeve center axes of the plurality of cylinder sleeves with respect to the radial directions respectively.
