操作器
摘要：
本发明提供一种具有可手动操作调节阀的阀轴且可固定在所期望的位置的奇异行星齿轮机构的操作器。该操作器(100)的特征在于，包括：恒星齿轮(3a)，其接收驱动马达(2)的转动力而转动；固定内齿轮(5)，其以包围恒星齿轮的形态固定配置，在其内周面具有轮齿；多个行星齿轮(4_1～4_3)，它们配置在恒星齿轮与固定内齿轮之间，与恒星齿轮和固定内齿轮啮合，一边在恒星齿轮的周围公转一边自转；可动内齿轮(6)，其与固定内齿轮同轴配置，在其内周面具有与行星齿轮啮合的轮齿，设置为能转动；输出轴(7)，其与可动内齿轮连结，用以转动调节阀的阀轴；以及手动操作机构(3b、8)，其通过从壳体(1)的外部施加的力来转动恒星齿轮或行星齿轮。
摘要（英）：

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.
