Title:
HYDRAULIC PUMP STRUCTURE FOR WIND TURBINE GENERATOR OR TIDAL CURRENT GENERATOR AND METHOD OF MOUNTING HYDRAULIC PUMP
Document Type and Number:
WIPO Patent Application WO/2012/073280
Kind Code:
A1
Abstract:
An object of the present invention is to provide a hydraulic pump structure which improves the ease of mounting the hydraulic pump on the main shaft, and a method of mounting the hydraulic pump which can be performed in a simplified manner. A hydraulic pump unit 10 is formed by unitizing a cylindrical member 46 fit into an outer circumference of the main shaft 12 and a hydraulic pump body 76 arranged on an outer circumferential side of the cylindrical member 46. The hydraulic pump body 76 comprises a ring cam 52 mounted on the outer circumference of the cylindrical member 46, a pump bearing 54, a pump housing 34, a plurality of piston 58 housed in the pump housing 34 and actuated by the ring cam, and a plurality of cylinders 60 which guide the plurality of pistons in a radial direction and are arranged in a circumferential direction, and the hydraulic pump unit 10 is configured such that the pump unit 10 is insertably fixed to the main shaft 12 by the cylindrical member 46.
