Title:
HYDRAULIC DEVICE AND DRIVE UNIT WITH SPEED REDUCTION MECHANISM
Document Type and Number:
Japanese Patent JP2017145851
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce, in a hydraulic device with a control shaft rotated around the axis by a drive motor, the size of the drive motor while preventing increase in the size with respect to the radial direction based on the axis of the control shaft.SOLUTION: A hydraulic device according to the present invention comprises: a control shaft tilting an output adjuster according to rotation around the axis; a drive motor generating rotational power for operating the control shaft around the axis; a drive shaft which is arranged on a reference axis of the same axis with the axis of the control shaft and is operatively driven around the axis by the drive motor; a speed reduction mechanism which reduces the speed of the rotational power operatively inputted from the drive shaft and outputs the same toward the control shaft; and a housing receiving a hydraulic rotor, an output adjuster, and the speed reduction mechanism. The speed reduction mechanism has a hypocycloid type speed reduction mechanism arranged on the reference axis.SELECTED DRAWING: Figure 2
