Title:
HYDRAULIC ELECTRIC MECHANISM AND HYDRAULIC ELECTRIC SYSTEM
Document Type and Number:
Japanese Patent JP2015151973
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic electric mechanism and a hydraulic electric system capable of transmitting heat from a rotator of an electric rotary machine to a hydraulic rotary machine side.SOLUTION: A hydraulic electric mechanism 18 is equipped with a hydraulic motor 19 and an electric generator 20. A rotary shaft 191 of the hydraulic motor 19 and a rotary shaft 201 of the electric generator 20 are spline-coupled. In the rotary shaft 191 of the hydraulic motor, a hydraulic fluid passage 191b for circulating a hydraulic fluid from a drain chamber 198a is provided. The hydraulic fluid is supplied into a clearance between teeth of a male spline portion and teeth of a female spline portion of a spline-coupling portion of the rotary shafts 191 and 201, through the hydraulic fluid passage 191b. The heat of a rotor 202 of the electric generator 20 is transmitted to the hydraulic motor 19 through the rotary shafts 191 and 201 in which the clearance of the spline-coupling portion is filled with the hydraulic fluid.
