SETTING/OPERATING DEVICE

摘要

A setting/operating device including: a sun gear that is rotated by a rotational force from a drive motor; a fixed internal gear fixedly disposed to surround the sun gear and having teeth on an inner peripheral surface; a plurality of planetary gears disposed between the sun gear and the fixed internal gear that rotate in engagement with the sun gear and the fixed internal gear while revolving around the sun gear; a movable internal gear disposed coaxially with the fixed internal gear, having teeth that come into engagement with the planetary gear on an inner peripheral surface, and provided so as to be rotatable; an output shaft coupled to the movable internal gear and configured to rotate the valve stem of the regulating valve; and a manual operation mechanism that rotates the sun gear or the planetary gear by a force applied from the outside of a housing.

1. A setting/operating device comprising:
a sun gear configured to rotate upon reception of a rotational force from a drive motor; a fixed internal gear fixedly disposed to surround the sun gear and configured to have teeth on a fixed inner peripheral surface; a plurality of planetary gears disposed between the sun gear and the fixed internal gear that rotates in engagement with the sun gear and the fixed internal gear while revolving around the sun gear; a movable internal gear disposed coaxially with the fixed internal gear, said movable internal gear being configured with teeth on a movable inner peripheral surface that come into engagement with the planetary gears and being configured to be rotatable; an output shaft coupled to the movable internal gear and configured to rotate a valve stem of a regulating valve; a housing that accommodates the sun gear, the fixed internal gear, the planetary gears, and the movable internal gear; and a manual operation mechanism configured to rotate one of the sun gear and the plurality of planetary gears by an external force.
