Title:
ELECTROMECHANICAL DEVICE, MOVABLE BODY AND ROBOT PROVIDED WITH THE SAME, AND TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2016201996
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve a reduced size and improved rigidity of an electromechanical device having a transmission mechanism.SOLUTION: An electromechanical device comprises: a first electromechanical mechanism section, a transmission mechanism section, a second electromechanical mechanism section and a load connection section for connecting a load to the transmission mechanism section, which have an identical central shaft as a center of rotation; and a housing body for housing them. A first housing space that is open at one side of the central shaft in an axial direction is formed at an inner peripheral side of a first rotor included in the first electromechanical mechanism section. A second housing space that is open at both sides of the central shaft in the axial direction is formed at an inner peripheral side of a second rotor included in the second electromechanical mechanism section. The transmission mechanism section is housed in the first housing space and the second housing space. Further, the transmission mechanism section comprises: a rotation input section integrally formed with the first rotor; a rotation output section integrally formed with the load connection section; and a rotation control section integrally formed with the second rotor for controlling a relationship between a number of rotations of the rotation input section and a number of rotations of the rotation output section in a variable manner.SELECTED DRAWING: Figure 30
