Document Type and Number:
Japanese Patent JP6887239
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric-motor direct connected type fluid pressure pump device enabling a standard fluid pressure pump of a fluid pressure pump manufacturer to be connected to a standard electric-motor of an electric-motor manufacturer and enabling simplification of management on it by reducing the type of the electric-motor without preparing any exclusive electric-motor.SOLUTION: This invention comprises an electric-motor 1 having a rotatable output shaft 5 protruded at one end side in an axial direction; a fluid pressure pump 7 for sucking and discharging working oil through rotational driving of an input shaft 8 protruded at one end side in an axial direction; a spacer member 13 connecting the electric-motor 1 with the fluid pressure pump 7; and a connecting member 15 stored in the spacer member 13. The spacer member 13 causes the electric-motor 1 and the fluid pressure pump 7 to be fitted and connected. The connecting member 15 connects the output shaft 5 of the electric-motor 1 fitted to the spacer member 13 with the input shaft 8 of the fluid pressure pump 7, the connecting member 15 is formed with a filling chamber 19 at a connecting part where the output shaft 5 is connected to the input shaft 8, and working oil lubricating the connected part is filled in the filling chamber 19.SELECTED DRAWING: Figure 1
